哈93216高蛋白大豆平衡施肥技术的试验研究

Study on the techniques of balanced fertilization on the high protein content of Har 93216 soybean

试验采用二次回归正交组合设计,建立了哈93216高蛋白大豆优质高产平衡施肥数学模型,然后采用二因素随机区组设计对磷钾用量作了进一步研究。结果表明:氮磷钾及一些微量元素肥料的合理施用对保持和提高哈93216大豆的产量及蛋白质含量是至关重要的,而且磷钾的变化所带来的影响相对要大一些。在试验区条件下,要使哈93216大豆产量>2250kg/hm2,同时蛋白质含量>44%,其氮、磷、钾的最佳配施方案应为:N78 8kg/hm2、P2O5143 1kg/hm2、K2O143 1kg/hm2,同时配施一定量的中、微量元素。

The orthogonal combination design of quadratic regression was adopted in the experiment to establish a fertilization model for obtaining high yield and high quality on the soybean of Har 93216 Then carried out further study on the adequate rate of phosphorus and potassium fertilization based on the design of two factors with randomized block design The result showed that the balanced fertilization of nitrogen, phosphorus, potassium and other trace elements was very important to increase yield and protein content of the soybean Har 93216 and the effect of P and K was more significant To meet the indexes of the yield more than 2250 kg/hm2 and the protein content more than 44% for the soybean of Har 93216 under the experimental condition, the optimum fertilization scheme should be: N 788kg/hm2, P2O5 1431kg/hm2, K2O 1431kg/hm2,respectively And at the same time adequate secondary and trace elements should be added
