栽培因子对合农63大豆产量的影响
Effect of Cultural Factors on Yield Characters of Soybean cv.Henong 63
摘要
Abstract
With three factors design of universal quadratic rotation combination,the models were established on the effects of density,fertilizer amount and sowing date on yield of soybean cv. Henong 63. According to the testing results,the quadratic regression model had better simulation effect. The mathematical model was; Y = 3763. 36788-217. 91412X12 -211. 01982X22 -275. 72009X32. The results showed that influencing order of three factors on the yield was sowing time > planting density > fertilizer. Two-factor interaction analysis showed thaE there was a positive interaction between sowing time and planting density, planting density and fertilizer,sowing time and fertilizer to some extent. By computer simulating,the cultivation combination to obtain seed yield above 3 282.2 kg·ha-1for Henong 63 was planted at 5th to 10th May with planting density of 25. 64-34. 36 plant·m-2 and fertilizer rate of 231. 4-243. 6 kg·ha-1.关键词
