小麦在生长中后期即孕穗、灌浆期喷施磷酸二氢钾具有增产效果。如果采用磷酸二氢钾与双氧水混喷,增产更显著,可大大提高经济效益。混喷磷酸二氢钾与双氧水是用肥少,见效快,成本低,简单易行,便于推广的小麦增产的新技术。增产的原因,主要是提高小麦后期吸肥能力,调节植株生理机能。小麦从孕穗到成熟是需肥高峰期,占全生育期的60—70％,这时植株上部叶片光合作用旺盛,营养物质的形成和转化十分活跃,根系日趋衰老,吸收
Wheat in the latter part of growth that is booting, filling potassium dihydrogen phosphate spraying has the effect of increasing yield. If the use of potassium dihydrogen phosphate mixed with hydrogen peroxide spray, increase production more significant, can greatly enhance economic efficiency. Mixture of potassium dihydrogen phosphate and hydrogen peroxide is to use less fat, quick, low cost, simple, easy to promote the new technology of wheat yield. The reason for the increase is mainly to improve the late absorption of wheat and adjust the physiological functions of the plants. Wheat from booting to maturity is the peak need of fertilizer, accounting for 60-70% of the whole growth period, when the upper leaves of plants photosynthesis, nutrient formation and transformation is very active, growing root aging, absorption
