【Abstract】 High-yield and disease-resistant soybean variety Suinong 22 was bred by Suihua Agricultural Institute of Heilongjiang Academy of Agricultural Sciences through sexual crossing,which was ap- proved by Heilongjiang Crop Variety Approval Committee in 2005.It has many characters such as lodging resistance,disease-resistant,short node,dense legumen,good airiness and light penetration, with protein and fat content 39.66% and 20.06%,respectively.The required active accumulated tem- perature was 2 400℃and its growth duration was 120 days.The average yield of within institute ex- periment in 2000 was 3 894.7 kg/hm~2,17.7% higher than that of check Hefeng 25.The average yield of the whole province yield experiment in 2004 was 2 426.1 kg/hm~2,12% higher than that of check Suinong 14.The suitable planting areas of Suinong 22 were the second accumulated temperature re- gions in Heilongjiang province,most relative accumulate temperature area of Inner Mongolia Autono- mous Region and Jilin province.It was suitable for narrow-row solid-seeded planting and the planting days was early in May,with a density of 300 000～350 000 stands/hm~2 and a basal fitilizer of 200 kg/ hm~2.更多还原
