Extending the life of sugarcane roots, cane farmers' income turned into a profit

Recently, in the dry land near the vegetable garden tun of Hemu Village, Hemu Town, Rongshui Miao Autonomous County, Guangxi, the vigorous sugarcane is like a green sea, swaying in the wind and making a "rustling" sound
.
In more than ten days, the sugar cane in the field will be harvested into the sugar factory to press the sugar
.

"You see, sugarcane grows tall, the replanted sugarcane should not be wrong this year's harvest, which expert invented the direct replanting technology of seeds, really thank him!" Looking at the 50 acres of sugarcane in front of him, Wei Kuanming, a big sugarcane planter, grinned at the corner of his mouth and laughed
.

From less than 2.
88 tons per mu in the 2020/2021 crushing season to more than 7 tons per mu in the 2021/2022 crushing season, faced with the dilemma of lack of cane and broken ridges, the Lao Wei family used the new technology of sugarcane seed stems to directly replant Sugen and extend the life of Sugen, which achieved increased sugarcane production and income, and staged a "counterattack"
to turn losses into profits.

"Sugarcane can only be harvested if it has mush", local cane farmers have been farming for many years and know this truth
.
"The new technology of direct replanting of sugarcane seeds and stems to extend the age of cedar roots developed by our team effectively solves the problem of insufficient effective stems caused by the lack of cane plants and ridges, improves the yield of cane and greatly reduces the production cost
of sugarcane planting.
" You Jianhua, science and technology commissioner and researcher of the Sugarcane Research Institute of the Guangxi Academy of Agricultural Sciences, said
.

Sugarcane cultivation urgently needs to extend the life of the cedar roots

In Guangxi, the sugar industry is a traditional advantageous industry, and it is also an important industry
in ethnic areas to consolidate the achievements of poverty alleviation and effectively connect rural revitalization.

Lack of cane plants and broken ridges is a problem
faced by many sugarcane farmers.
"Sugarcane is a crop that has been harvested for many years at a time, and it is inevitable to encounter the harm of pests and rats, low temperature weather and frost during the growth period, coupled with the influence of human and animal trampling, machine crushing, drought and other factors during the harvest period, the underground cane buds are damaged to varying degrees, resulting in the lack of cane ridges and ridges becoming more and more serious
.
" You Jianhua said
.

At present, the production cycle of sugarcane planting in Guangxi and even China is generally 3 years, and the fourth year is replanted, while the sugarcane root life of major sugar-producing countries such as Brazil is 5 to 8 years
.
"Sukan cane is an important part of sugarcane production, and extending the life of cedar root is one of the
most effective ways to reduce costs and increase efficiency in sugarcane planting.
" You Jianhua said
.

You Jianhua told reporters that the traditional method of transferring dense and thinning and seedling transplanting is to use the same source and relatively consistent growth period of cane seedlings for transplanting and replanting to extend the age of the root, but there are many drawbacks of long "rejuvenation period" and heavy reliance on water sources as a guarantee, and the operation requires a lot of manpower, material resources and financial resources, and more than 70% of sugarcane in Guangxi is planted in dry slopes lacking water sources, so it has little effect, it is difficult to form effective stems to achieve the purpose of making up for the lack of plants and ridges, and it is difficult to adopt large-scale
。

How to deepen research on cultivation techniques to extend the life of the roots? This has become an urgent problem to be solved in China's sugarcane industry, and it has also become a topic
that You Jianhua's team has been tackling for many years.

New technology enables enterprises and cane farmers to achieve a "win-win" situation

A gentle breeze blows, and the green sugarcane forest ripples
.
In Xintun, Yolou Village, Hemu Town, Rongshui Miao Autonomous County, Jia Zhaoxiong, a major sugarcane planter, walked through a narrow and sharp sugarcane forest to check the growth of sugarcane using the new technology of direct replanting of
sugarcane stems to extend the age of Sugen.

"Without this new technology, the cane fields would have been forced to be replanted in early 2020, and after adopting this technology, the cane fields have been extended for three years and can maintain a yield of more than
6 tons per acre.
" Jia Zhaoxiong said
.

The use of new technology to remediate Sugen cane land has turned cane farmer Liao Jinying into a profit
.

After carrying out replanting in accordance with the technical plan, Liao Jinying strengthened the management and protection of the field, and the growth of cane plants was generally good
.
In the 2021/2022 crushing season, Liao Jinying cut more than 353 tons of raw cane, minus the cost of replanting cane seeds and labor and other expenses of more than 8,000 yuan, and her net income reached 100,000 yuan
.

"Last year, we increased production and income, and this year we continue to micro-replant, while applying fertilizer and weeding early, and now the sugarcane is growing very well, and we expect to cut more than
350 tons of raw cane in the 2022/2023 season.
" Liao Jinying said
.

You Jianhua introduced that under the joint funding of the relevant national sugar industry technology system post expert project and the Guangxi Agricultural Key Science and Technology Plan Project, their team developed the core cultivation technology of Sugen cane production, and the supporting self-selected sugarcane seed "Gui Hui 98-296" solved the problem of lack of extensive supplementation of seed sources, and also broke the traditional mode of single planting of sugarcane varieties in China, which effectively increased the yield of Sugen cane, greatly reduced the cost of sugarcane planting and production, and extended the age of Sugen by more than 2 years
。

The comprehensive results of the former Guangxi Department of Agriculture organizing expert production testing and acceptance and many years of demonstration, production and application in various places showed that the yield of sugarcane area directly replanted with the new technology of direct replanting of sugarcane stems to extend the life of Sugen was not lower than that of the previous stubble cane, which was more than 30% higher than
that of the control (no replanting, the natural state of Sugen cane).

Since May 2016, the team has obtained a total of 7 invention patents, utility model patents, computer software copyrights and other independent intellectual property rights
such as "a method to extend the roots of sugarcane".
In August 2018, the local standard "Technical Regulations for the Direct Replanting of Sugar Cane Seeds and Stems" drafted by You Jianhua and others was issued by the Guangxi Bureau of Quality and Technical Supervision
.

Sugar companies have also seen hope
to solve the bottleneck problem of extending the life of cedar cane.
Starting from 2019, Guangxi Fengtang Luzhai Sugar Co.
, Ltd.
will give a subsidy of 200 yuan
per mu to cane farmers who apply the new technology of direct replanting of sugarcane seeds to extend the age of their cane stems.

"From the perspective of the promotion and application in recent years, the life of Sugen can be extended by 2-3 years, and the yield can be increased by 1 ton to 1.
5 tons, and the effect of increasing production is obvious, and enterprises and cane farmers have achieved a win-win situation
.
" Liao Yunrong, deputy head of the agricultural department of Guangxi Fengtang Luzhai Sugar Co.
, Ltd.
, told reporters
.

You Jianhua said that the team has jointly developed the "Seed Stem Direct Replanting Cane Planting Machine" with relevant enterprises, and the next step will be to explore the realization of mechanized direct seed stem replanting operations to further improve production efficiency and help Guangxi's "sweet business" reach a higher level
