测土配方施肥是对农作物进行合理施肥的一种技术手段,采用此技术不但可以提高农作物的产量和品质,还能减少因不合理使用化肥而产生的环境污染。基于此,通过采集土样化验、田间小区肥效试验和校正试验,获得一个地区冬玉米生产的土壤养分供肥量、肥料利用率、施肥量、施肥比例和施肥方法,达到节本增产的效果,从而为种植者提高冬玉米的产量提供依据。
Soil testing and formula fertilization is a technical means of fertilizing crops rationally. Using this technology can not only improve the yield and quality of crops, but also reduce the environmental pollution caused by irrational use of fertilizers. Based on this, soil nutrient supply, fertilizer utilization rate, fertilization rate, fertilization ratio and fertilization method of winter maize production in a region were obtained by collecting soil sample test, field plot fertilizer efficiency test and calibration test, Thus providing the basis for growers to increase the yield of winter maize.
