摘要
1994～ 1 996年在黑龙江省东部湿润、半湿润地区 ,西部风沙干旱土区 ,北部高寒黑土区 ,中部和南部黑土区进行了耐抗重迎茬大豆品种 (系 )筛选 ,控制重迎茬减产农艺措施和有效制剂试验研究。通过三年五个生态区试验 ,筛选出一批适合各区种植 ,耐抗重迎茬大豆土传根部病虫害、丰产性好的品种 ,如嫩丰 1 5、抗线 1号、合丰35、黑农 39、黑交 92 -1 544和绥农 1 0、黑农 35等。缓解剂加施钾肥 ,增施有机肥 ,破垄夹肥和深松 ,多种种子包衣剂和大豆增效剂 。
In 1994-1996, in 5 different ecoregions of Heilongjiang province some field experiments were conducted. These experiments include screening of soybean cultivars(lines) for resistance or tolerant to continuous and alternate-year soybean cropping, and test on management practices and preventive agents selection for continuous and alternate-year cropping. The experiments results indicated that some cultivars(lines) are resistant to soil-borne diseases and pests of soybean root of continuous and alternate-year cropping and with high yield, such as Kangxian 1, Hefeng 25, Heinong 39, Heijiao 92-1544, Suinong 10 and Heinong35. Agronomic management potassium fertilizer, application of organic fertilizer, splitting of ridges for adding fertilizer, deep digging, and several seed-coat-agents are recommended, special agents for continuous soybean cropping can reduce effectively soybean yield loss of continuous and alternate-year cropping.
