如何根据小麦的产量指标来确定施肥量,以及什么时候追肥最为合理?我区群众在生产实践中积累了不少经验。但为找出有关依据,就需要从养分的吸收利用上进行实际的测定。众所周知,小麦对养分的吸收利用情况,依品种、土壤肥力、气候条件以及耕作栽培措施的不同有很大差别,同时还由于测定工具、方法上的条件所限,目前仅采取少量样品作化验分析,只能得一概略数据。今就我所王太堡农业试验场近年来进行墨卡小麦高产栽培试验中初步测定的一些结果作一简介,供参考。
How to determine the amount of fertilizer according to the output of wheat, and when is the most reasonable top dressing? My district people in the production practice has accumulated a lot of experience. However, to find the basis for the need to absorb nutrients from the actual measurement. It is well-known that the absorption and utilization of nutrients by wheat vary widely according to the species, soil fertility, climatic conditions and tillage and cultivation measures. At the same time, due to limited measuring tools and methods, only a few samples are used for laboratory analysis , Can only get a rough data. Now my Wang Taibao Agricultural Experimental Field in recent years for the high yielding cultivation of wheat card experiments in some preliminary results for a brief introduction for reference.
