Science and technology "leading" strong support to stabilize grain and expand beans and double harvests

In winter, the land of Jianghuai is busy, and the soybean and corn belt compound planting of Jiangsu Agricultural Reclamation Agricultural Development Co.
, Ltd.
(hereinafter referred to as Suken Nongfa) ushered in the highlight of
"cross-rolling".
In the first year of stabilizing grain and expanding beans, Suken Agricultural Development effectively played the role of the "national team" to ensure national food security and the effective supply of important agricultural products, coordinated the adjustment of grain and oil planting structure, fully promoted new technologies and new models of soybean and corn belt compound planting, and fully implemented the target task
of 100,000 mu issued by the provincial government 。 Suken Agricultural Development Co.
, Ltd.
has made collaborative innovation in the whole process of variety selection, technical support, agricultural machinery agronomic collaboration, etc.
, deeply explored the potential of soybean and corn intercropping to increase yield and comprehensive benefits, effectively overcome the contradiction of grain and oil land competition, and made the harmonious symbiosis and coordinated production increase of grain and beans become a reality, truly achieving the expected goal
of "corn yield does not decrease, harvest one more season of beans".

Layer by layer refinement

Ensure that the planting area is on the ground

In order to comprehensively improve the self-sufficiency rate of soybean oil and promote the compatible development of soybean and corn, Suken Nongfa promoted soybean corn belt compound planting according to local conditions, and shouldered the responsibility of state-controlled modern agricultural listed companies
.

In mid-February 2022, after receiving the task, the company immediately established a working leading group composed of the main leaders of Jiangsu Agricultural Reclamation Group, and dispatched crack forces to establish three technological innovation and promotion working groups of cultivation, plant protection and agricultural machinery; In just 50 days, 43 cultivation, plant protection and agricultural machinery technology seminars and work arrangement meetings were intensively held, and the soybean and corn belt compound planting work plan and cultivation and plant protection technical regulations, test and demonstration work plans were quickly introduced.
Establish the "4+4 model" (4 rows of single flour corn and 4 rows of soybeans) as the company's main planting mode
.
As the saying goes, "thyme, thyme beans" refers to the smaller adaptation range of soybean varieties
.
According to its own geographical and climatic conditions, the company chose "Suyu 34" and "Qi Huang 34" as the main cultivars of corn and soybean respectively, and showed good suitability and yield in the later stage
.

The company selected Huaibei as the main planting area, and Huainan took the task of trial planting, concentrated 6 branches such as Dongxin, Gangbu and Binhuai with strong strength to participate in planting, and coordinated the construction of
10,000 mu area, 1,000 mu area and 100 mu area.
Each family has reserved 50-15,000 mu of reserve additional area to cope with various force majeure
.
Each strengthened linkage and rationally allocated planting area to ensure that 100,000 mu of soybean corn was sown on
schedule.

Do not fight unprepared battles
.
To improve the quality of sowing, the key is to have supporting hardware support
.
The sowing needs of corn and soybeans are different, and the company actively produces and modifies the matching sowing equipment to solve the problem
of inorganic availability or insufficient equipment for compound planting.
In April 2022, the design, trial production and selection of the seeder were completed, and the air curtain special plant protection machine was independently developed to accelerate the docking with enterprises and produce prototypes
.
The agricultural machinery innovation and promotion team designed and developed a closed special plant protection machine according to its own agricultural characteristics, and overcame the problem of
plant protection.
In addition to the "hardware" factor of the supporting tools, the sowing quality is also closely related
to the "software" factor of the operation of the agricultural machine.
The company has repeatedly carried out management and technical training for technicians, drivers and grass-roots management personnel of the branch, and done a good job in technology promotion
.
At the same time, the company also introduced the "Soybean and Corn Belt Compound Planting Labor Competition Program" to promote promotion, create an atmosphere of catching up with and surpassing learning, and stimulate the enthusiasm and motivation
of cadres and employees.

Focus on the hard points

The "troika" escorted the whole process

The company adheres to the model of supporting good seeds and methods, combining agricultural machinery and agronomy, and disaster prevention and mitigation coordination, so that the "troika" of seeds, technology and agricultural machinery can give full play to its advantages
.

We should grasp the procurement of corn and soybean seeds as early as possible, and strictly carry out preliminary inspection and processing
.
In view of the main promotion of the "4+4 model", we continue to improve the technical plan, arrange relevant tests in advance for the technology that is still not clear, and specially build greenhouses for closed removal and safety tests, and strictly control food security
.
Actively carry out all kinds of technical training, determine the general idea of "selecting varieties, expanding the light, shrinking the plant confidentially", and organize expert lectures, internal training, on-site observation, etc.
; Adhere to the combination of online and offline training and guidance, hold planting technology video training meetings on demand, strengthen technology promotion, and improve the level of
seed management.

From March to April 2022, affected by the multi-point spread of the epidemic, the company encountered multiple problems such as the inability of factory technicians to enter the field, the obstruction of the transportation of agricultural machinery technical transformation accessories, and the difficulty of agricultural material transportation, and there was no agricultural machinery such as seeders and plant protection machines that met the needs on the market.

Extreme weather is frequent, and the company is based on proactive disaster response
.
In view of the problems of pre-sowing drought and soil compaction, increase the number of rotary tillage and grasp the sowing quality; In summer, the rain and waterlogging disaster was serious, and the company mobilized more than 4,000 people to clean ditches and drain water; Purchase piggyback fertilizer spreaders, timely carry out chemical removal and fertilization, and ensure that the seedling stage is not missed; In mid-August, soybean corn flowering suffered the most serious high temperature and heat damage, the company timely organized irrigation to replenish moisture, spray foliar micro-fertilizer, improve the field microclimate, enhance corn and soybean resistance
.

Break through and conquer the pass

The results of "one place, two harvests" are gratifying

"Soybean rattle"
.
In the autumn and October, the soybean and corn belt compound planting in Suken has entered the harvest season, and "one field, two harvests" has become a different scenery
on the fields in the autumn of 2022.
Can be different plant height, different row width, how to "unite" the machine harvest? The cadres and employees of the branch that undertake the task of compound planting of soybeans and corn give up holidays, stick to it day and night, exert ingenuity and vigor, and do not let the harvest
be rushed.

The management personnel of Xincao Agricultural Machinery Terminal and Shuguang Production Area made full use of the high temperature weather to rush (test) to harvest 200 mu of soybeans, accurately grasp the harvest timing of the two crops, and repeatedly debug the harvesting equipment to the best state
.
All the staff of Yuntai Branch work hard in the field, formulate the harvesting progress and sequence according to the maturity of the field, see the sewing needle, harvest one piece when mature, and rake one piece to ensure that the pellets are returned to the warehouse
.
Binhuai Branch boldly adopts technical transformation, installing a profiling plate under the header to harvest the fallen soybeans into the header, and put the header to the minimum, reduce the leakage phenomenon caused by bumps, and effectively control the harvest loss rate
。 Huanghai Branch urgently handled insurance for soybean harvesters and corn ear pickers, actively contacted customers, and exported more than 1 million jin of corn during the National Day in 2022; Urgently hold the "three autumn" work promotion meeting, focusing on the distribution of corn and soybean harvesters, harvesting and seeding before rain, and field management; The rush to harvest and plant 6,000 mu of corn and soybeans is the result of
all cadres and workers sticking to the ground day and night.
During the National Day period, Dahua Seed Group made every effort to ensure the safety of the seed source of its own varieties, vigorously grasped the miscellaneous work, reasonably organized workers to work overtime, set up a field inspection team, and inspected the impurity removal situation at irregular times every day to ensure the quality of
the seeds in the warehouse from the source.

As the agricultural proverb goes, "Corn with soybeans, ten years and nine years without leakage"
.
But with more links and increased costs, can the comprehensive benefits be "overcharged"? No matter how the planting model is adjusted, the beneficial model is the good model
.
Despite repeated natural disasters during the growth period, the first year yield benefit target
was successfully achieved.
Among them, the Gangbu branch achieved a corn yield of more than 800 jin, and the soybean yield of Xincao branch exceeded 160 jin, which strengthened the confidence
to win the battle of corn and soybean belt compound planting.

While increasing income, the effect of pest control is more obvious
.
Comparative data show that soybean corn planted in the same field increases biodiversity, the incidence of pests and diseases is significantly reduced, the frequency and amount of pesticide application are reduced by 2-3 times and 25%, respectively, and the incidence of soybean diseases and pests is reduced by more than 30%, which can effectively reduce the use of pesticides and promote the green development of
agriculture.
At the same time, through "one season and double harvest", the combination of
planting and breeding can also be realized.
Soybean with nitrogen fixation, alternating crops with corn belts every other year, can improve soil fertility and soil looseness, and several branches participating in the early pilot have tasted the sweetness
.

The autumn grain harvest is in hand, the warehouse is sufficient, and the overall situation is stable
.
Promoting soybean and corn belt compound planting is a strategic means to ensure national food security, and is an important technical measure
for land use and land cultivation and to promote sustainable agricultural development.
Under the background of stabilizing grain and expanding beans, Suken Nongfa grasped the opportunity of planting structure adjustment, optimized the planting mode and stubble layout, promoted the compatible and coordinated development of soybean and corn belt compound according to local conditions, and did everything possible to improve planting efficiency and production efficiency, and embarked on a new path
of stable grain and bean expansion with Suken characteristics 。 "To ensure grain for the country and increase production for the people", the next step of Suken Agricultural Development will be based on the goal of consolidating the foundation of food security in an all-round way, focusing on optimizing the structure of grain and oil planting, accelerating the promotion of applicable varieties and technologies, exploring a symbiotic and coordinated development model, continuing to promote the upgrading of the whole industrial chain of grain and oil crops, and making greater contributions
to ensuring national food security and improving the self-sufficiency rate of soybean oilseeds.
