摘要
富锦是黑龙江东部重要的大豆生产基地,播种面积16万hm2以上,占全市耕地面积的50%。连年的重迎茬种植,加快了大豆孢囊线虫的繁殖和孢囊在土壤中的积累。大豆孢囊线虫病是富锦市大豆重迎茬显著减产、持续减产的主要原因。应用抗病品种是防治大豆孢囊线虫最经济有效的措施。抗线虫大豆品种的应用取得了极显著地抗病增产效果,累计推广面积达15万hm2以上。
Fujin is the important soybean production base in the East of Heilongjiang province. The soybean perennial sown area is about 160 000 hm^2 , accounted for more than 50% of total cultivated land. The continuous soybean cropping in the successive year accelerated reproduction and accumulation of SCN in soil. The soybean cyst nematode disease is the main cause of remarkable lasting yield reduction. The application of soybean resistant vari- eties is the most economical and effective method. It attained significant effect of disease resistance and high yield. The accumulation area of extending was up to 150 000 hm^2.
