Industrialization of development of new varieties with high quality and yield of 100000 Mu Summer Maize in Shandong Province

Introduction: on January 8, the distribution quotation of imported soybeans in some domestic ports was stable At the end of 2003, Shandong developed 100000 mu of new summer maize varieties with high quality and high yield The main tasks are as follows: first, implement the industrialization development area of 100000 mu of new summer maize varieties with high quality and high yield, increase the per unit yield of corn in the development zone from 550 kg to 700 kg, and increase the per unit yield of corn in the project area by more than 150 kg GNX 2 Through the demonstration and development of new varieties and new technologies, a strong demonstration field and model field will be formed The coverage rate of new technology popularization and improved varieties will reach 99% and 100% respectively, and the contribution rate of science and technology will reach more than 58% Third, through development, the agricultural production capacity has been strengthened, with an increase of 20% - 30%, a gross income of 147 yuan and a profit of 14.2 yuan per mu This year, under the weather conditions of rainy, low temperature and low temperature during the whole growth period of summer maize, the project development has achieved remarkable results After the Provincial Department organized relevant experts from Shandong Agricultural University and other units to test and accept the production, the development area of the project area is 100000 mu, with a unit yield of 714.9 kg, and all tasks have been successfully completed According to the requirements of the project feasibility study report and implementation plan, GNX selected 100000 Mu project area in Suo Town, Jiangtun town and Xigang town of Tengzhou City, covering an area of 40000 mu, 30000 Mu and 30000 Mu respectively, and arranged 40 mu high-yield demonstration field for new varieties Under the leadership of the leading group, the production department, the agricultural technology station, the soil fertilizer station, the seed station, the plant protection station and other departments and affiliated units, the corn Institute of the Provincial Academy of Agricultural Sciences, the Denghai seed industry group, the Zaozhuang Agricultural Bureau, the Tengzhou municipal government and other departments work together to seriously formulate and implement the implementation plan, take the science and technology as the guide, the material as the basis, and the administration as the guarantee, and strive to improve the production conditions, which is unfavorable this year Under the climatic conditions of agricultural production, the corn in the project area will be harvested again During the implementation of the project, 8 new varieties (lines) such as Ludan 981, Ludan 984, Denghai 3707, Denghai 1 and Jinhai 5 will be introduced for demonstration, and 2 new varieties suitable for planting in Tengzhou, Ludan 984, Denghai 3707 and 37 new corn lines will be introduced 5 seedlings will be screened out through the test field New line of head According to the requirements of the implementation plan, take an agricultural sample of 500 mu, 20 agricultural samples and 4 microelements samples, analyze the soil nitrogen, phosphorus, potassium, organic matter, boron, iron, zinc and other microelements, implement the formula fertilization area of 100000 Mu according to the test results, purchase 250 tons of urea nitrogen fertilizer, 150 tons of diammonium phosphate, 250 tons of potassium chloride and 20 tons of microelements fertilizer, and increase each mu The application of wodifeng 100 kg organic fertilizer improved soil fertility 23 sets of instruments and equipment and 120 sets of agricultural machinery were purchased Experts from Shandong Agricultural University, provincial agricultural technology center and other relevant departments are invited to provide technical training for farmers in the project area before sowing, seedling stage, bellmouth stage and heading stage Through the promotion of more than 10 technologies, such as close planting, formula fertilization, straw returning to the field, biological control of pests and diseases, water-saving irrigation and assembly of supporting "seed, set, close, change and late", the pace of popularization and application of new technologies and varieties in the project area has been accelerated, the scientific and cultural quality and scientific farming level of farmers in the project area have been comprehensively improved, and the corn production in the surrounding area has been promoted from high-yield type to high-quality and efficient type Development: by increasing investment in science and technology, improving soil fertility, supporting improved varieties and methods, implementing standardized production and industrial development, the average per mu yield of the development field of 100000 mu of summer maize with high quality and high yield in the project area has reached 714.9 kg, 164.9 kg more than the 550 kg before development, 264.9 kg more than the undeveloped plot, and 1.16 yuan per kg at the current market price, an increase of 264.9 kg more than the Mu before development The income is 191.3 yuan, with an annual increase of 19.13 million yuan, an increase of 3.073 million yuan over the undeveloped mu, and an annual increase of 30.73 million yuan At the same time, through the implementation of the project, not only improve the yield and quality of corn in the project area, improve the scientific and technological awareness of farmers and the conversion rate of scientific and technological achievements, but also promote the production of summer corn in the surrounding areas to a higher level GNX maize is an important grain crop in Shandong Province, which plays an important role in agricultural production Therefore, governments at all levels have always attached great importance to corn production In recent years, with the gradual improvement of agricultural production conditions and the continuous increase of materials and technology input, the production level and scientific and technological content of corn in the whole province have been improved to a certain extent However, there is no breakthrough in maize production due to the variety, disorder, poor quality, low commodity, non matching cultivation technology, low output value and comprehensive benefits The purpose of the project is to promote demonstration of 100000 mu of corn and improve its supporting technology by screening excellent varieties of corn, so as to increase the yield of corn by 150kg per mu, and increase the value by 147 yuan per mu, so as to drive the corn production to a new level GNx
