| 摘 要： | 在杂选3号高产防病栽培中,选择磷、钾、硼、氮四个主要肥料因子,采用一次回归正交试验。结果表明:磷、钾、硼、氮配合施用可显著地提高杂选3号的产量,不同肥料因子的增产作用有别,依次是P>K或B>N。配合施用的同时对提高植株的抗病性,减轻病害发生的效果也明显,影响大的是K和N,二者作用相反,最适宜的经济配施用量为每667m2施用P(24～26kg)、K(10～15kg)、B(1.0～1.5kg)、N(10～20kg)。

| Abstract: | In the cultivation of No.3 mixed choose high production preventing disease,choosing the four main fertilizer factors such as phosphorus,potassium,boron,nitrogen to use a return orthogonal experiment. The result indicated that phosphorus,potassium,boron,nitrogen coordination employment may obviously enhance No.3 mixed choose output. Production increase function to different fertilizer factor is different. It is P>K or B>N in turn. Coordinate employment at the same time to enhance the plant disease resistance,reduce the effect which plant disease occurs also to be obvious. K and N'affect is big. The two function is opposite,is suitable for the economy match employment quantity to employ for each 667m2 P(24~26kg),K(10~15kg),B(1.0~1.5kg),N(10~20kg). |
