先后通过对中牟潮土、镇平砂姜黑土、许昌褐土3个土类进行田间小区试验,系统地研究了6种钾素水平对强筋小麦群体动态、产量及产量因子的影响.结果表明:三类土壤上适量施钾,可有效提高强筋小麦越冬群体、最高群体和有效群体.多点钾肥试验结果表明:钾肥主要通过增加千粒重显示其肥力效应.增产幅度一般在10%左右.在氮磷充足的前提下,小麦对钾的吸收存在着"奢侈吸收"现象.

Including the field plot experiment, we had orderly studied the effect of group dynamics of the strong gluten flour wheat, yield and factors of yield, by the six potassium levers in the zhongmou fluvo-aquic soil, zhenping vert soil and xuchang brown soil. Regular potassium fertilizer could lead the increasing of the winter group, the highest group and effective group of the strong gluten flour wheat. Fertilization of potassium mainly enhanced the 1000-seed weight ieveal their fertility effect again potassium through some potassium test result. Potassium increased the yield of wheat about 10%. Baaed on the premise that nitrogen and phos-phorus was sufficient, wheat's absorption to potassium had "luxurious to absorb" phenomenon.
