薄地小麦有机肥氮磷化肥正交试验

目的]探讨低产薄地麦田创高产的施肥方法。方法]对薄地小麦当年度创高产进行研究。结果]在小麦产量为750~1 500kg/hm2的低产田,施优质有机肥7.5万kg/hm2,尿素375~450 kg/hm2,标准过磷酸钙1 125~1 500 kg/hm2,有机肥、磷肥全部基施,氮肥采取"少吃多餐"的施用方法,当年度小麦产量可达6 000~6 750 kg/hm2,甚至更高。结论]该研究可作为低产薄地麦田创高产的参考。

Simple Conclusion on Orthogonal Experiments of Organic Fertilizer and Nitrogenous and Phosphorus Chemical Fertilizer on Wheat Planted in Barren Soil

Objective] The study aimed to discuss the fertilization method of realizing high yield in the wheat field with low-yield and barren soil.Method] The study on realizing high yield in the wheat field with barren soil in the current year was conducted.Result] In the low-yield field with wheat yield at 750～1 500 kg/hm2,the organic fertilizer with good quality,urea and standard calcium superphosphate were applied at 7.5×104,375～450 and 1 125～1 500 kg/hm2,the organic and phosphorous fertilizers were completely applied as base fertilizer and the nitrogen fertilizer was applied with the application method of applying for more times with less dosage at each,thus,the wheat yield in the current year could reach 6 000～6 750 kg/hm2,even higher.Conclusion] The research could be the reference for realizing high yield in the wheat field with low-yield and barren soil.
