旱地土壤耕层浅,保肥能力差,小麦中后期往往缺肥,造成每亩穗数上不去,穗粒数少,千粒重低。针对这种情况,湖南农学院和娄底地区农业局等单位经过二年的试验示范,在实行小蔸密植的基础上,总结出了一套亩产300公斤小麦的施肥改术:重施底肥保稳长,早施苗肥促分蘖,适施保蘖肥促成穗,巧施剑叶肥增粒数,叶面喷肥增粒重。即每亩施足纯氮16～18公斤,而各期肥料的分配:底肥4份,苗肥3份,保蘖肥2份,剑叶肥一份。其具体施用方法是:
Dryland soil tillage shallow, poor fertilizer retention ability, wheat is often lack of fertilizer in the late, resulting in per acre less spike, less spikelets, grain weight is low. In response to this situation, Hunan Agricultural College and Loudi Prefecture Bureau of Agriculture and other units after two years of pilot demonstration, the implementation of the small dense planting on the basis of summed up a set of 300 kilograms per mu of wheat fertilization surgery: re-applied fertilizer Stable, as early as the role of seedling fertilizer tillering, applied to ensure tillering fattening spike, clever Shi Jian Ye fat by grain, foliar fertilizer by grain weight. That is enough per acre of pure nitrogen 16 ~ 18 kg, and the distribution of various fertilizer: the base of 4 parts, 3 parts of seedling fertilizer, tillering fertilizer 2 parts, a leaf blade fertilizer. The specific method of application is:
