测土配方施肥是精准农业的一项重要技术,其核心是准确计量,使各种养分形成科学配方。不同地域、不同土壤养分含量差异很大;不同作物所需养分不同;同一作物的不同品种、不同生长阶段需肥规律也不同。因此,在播种前就要根据土壤性质、产量目标来确定肥料种类和施用方式,这就需要进行测土配方。只有科学、精确施肥,才能达到提高农产品质量、降低生产成本、增加收入的目的。本栏在上期已经对玉米的测土配方施肥技术进行了系统介绍,本期继续就小麦、水稻、大豆三大粮食作物的营养特性和施肥技术进行重点介绍,希望对农民朋友有一定的帮助。
Soil testing and formula fertilization is an important technique of precision agriculture. Its core is accurate measurement, which makes all kinds of nutrients form a scientific formula. Different regions, different soil nutrient content varies greatly; different crops require different nutrients; different varieties of the same crop, different growth stages require fertilizer law is also different. Therefore, it is necessary to determine the type and application of fertilizer according to soil properties and yield before sowing, which requires soil testing and formulation. Only scientific and precise fertilization can achieve the purpose of improving the quality of agricultural products, reducing production costs and increasing incomes. This column in the previous period has been on soil testing and fertilization of corn technology were introduced, the current issue of wheat, rice, soybeans and other three major food crops nutrition characteristics and fertilization techniques are introduced, I hope the farmers friends have some help.
