Heilongjiang's soybean yield breaks the national record and exceeds the United States in per unit yield

Introduction: Daxijiang farm of Jiusan branch of Heilongjiang General Bureau of agricultural reclamation, after many years of experiments, adopts the new technology of biological and light falling film mulching to plant soybean, with an average per hectare yield of 3000 kg, an increase of more than 30% compared with the original ridge three cultivation technology, and an increase of 1500 yuan per hectare This year, they planted 120000 mu of mulched soybeans, breaking the national record for large-area mulching, and the output per hectare will exceed the world's leading level of nearly 300 kg in the United States Once entering Daxijiang farm, the vast land is full of "white ocean", which once became the topic of discussion around people With China's accession to the WTO, facing the increasingly fierce market competition, state-owned farms will face great challenges Daxijiang farm, located in the semi-arid area, has a low soybean yield due to the constraints of natural conditions Facing the challenge of entering WTO, Daxijiang farm, as a non GMO high oil soybean demonstration farm of the Ministry of agriculture, has increased investment in science and technology Through two years of experiment and comparison, it is concluded that the cultivation technology of soybean film mulching has the advantages of conserving soil moisture, raising soil temperature, conserving fertilizer, inhibiting weeds and preventing soil erosion The average yield per hectare is 3000 kg, 30% higher than the original cultivation technology of ridge three Last year, the income per hectare increased by 1500 yuan This year, Daxijiang farm popularized the cultivation technology of soybean film mulching in a large area After 10 days of rush sowing, 120000 mu of soybean film mulching was planted, accounting for 70% of the total soybean planting area This year, we will strive to achieve 3200 kg per hectare, not only breaking the national average of 1720 kg per hectare, but also surpassing the world's highest level of 2710 kg per hectare in the United States By the end of the year, the soybean output of the whole farm will be increased by 8000 tons and the income will be increased by 12 million yuan.
