大豆黑农87、黑农88在黑龙江省青冈县的种植模式探索
Planting Pattern of Soybean Heinong 87 and Heinong 88 in Qinggang County,Heilongjiang Province
摘要
Abstract
In order to promote the popularization and application of high oil variety Heinong 87 and high protein variety Heinong 88 in Qinggang County,Heinong 87 and Heinong 88 were used to carry out rhizobia inoculation test,fertilization test and planting density test to study the suitable planting mode of Heinong 87 and Heinong 88 in Qinggang County.The results showed that rhizobium inoculation technology could improve the yield and quality of Heinong 87 and Heinong 88,but the effect was not significant.The yield of Heinong 87 was 4 438.50 kg·ha-1 when the fertilizer amount was 300 kg·ha-1,which was significantly higher than that at 225 kg·ha-1(4 306.50 kg·ha-1)and 375 kg·ha-1(5 052.30 kg·ha-1).The yield of Heinong 88 was 4 793.30 kg·ha-1 when the fertilizer amount was 300 kg·ha-1,which was significantly higher than that of the other two fertilizer levels.The highest yield of Heinong 87 and Heinong 88 were 3 778.00 kg·ha-1 and 4 197.00 kg·ha-1 respectively under the condition of 260 000 plants·ha-1.The yield of Heinong 87 was second at 280 000 plants·ha-1,and the yield of Heinong 88 was second at 260 000 plants·ha-1.Therefore,the optimum fertilization amount of Heinong 87 was 300 kg·ha-1,and the suitable planting density was 260 000-280 000 plants·ha-1.The optimum fertilization amount of Heinong 88 was 300 kg·ha-1,and the suitable planting density was 240 000-260 000 plants·ha-1.The results provide a scientific basis for planting Heinong 87 and Heinong 88 in Qinggang County,and lay a theoretical foundation for further research on the suitable planting mode of Heinong 87 and Heinong 88.关键词
