2014年秋季小麦配方肥验证及锌肥试验技术

Validation of Wheat Formula Fertilizer in Autumn,2014 and Zinc Fertilizer Test Technique

[目的]为了校正肥料参数,改进测土配方施肥技术。[方法]选用小麦品种"皖麦47",考察不同含量的配方肥和锌肥对小麦作物的增产效果。[结果]基肥中增施磷钾肥促进苗期生长有限,主要是增加光合产物及其运输,促进穗分化,增加穗粒数,提高产量;锌肥促进小麦生长,尤其是促进早分蘖、提高分蘖成穗率、增加有效穗。[结论]基肥中适量增施磷钾肥、锌肥,增穗增粒,能较大幅度提高小麦产量。

[ Objective ] The research aimed to correct the fertilizer parameters and improve the soil testing technology of applying fertilizer. [ Method ] Taking wheat variety Wanmai 47 as material, the yield-increasing effects of different content of formula fertilizer and zinc fertilizer were studied. [ Result] Increasing application of phosphate and potash fertilizer in basal fertilizer could promote the growth of the seedling limited]y, increase photosynthetic product and its transportation, promote the spike differentiation, and increase the number of grain per panicle, and the yield. Zinc fertilizer could promote the growth of the wheat, especially promote the early tiller, increase the percentage of earring-tillers and the effective panicle. [ Conclusion ] The application of phosphate, potash fertilizer and zinc fertilizer in the base fertilizer can increase the numbers of grains per ear and grain yield, and greatly raise the wheat yield.
