农业生产要持续发展,必须实行科学的施肥制度。在现代农业生产中,施肥既要保证作物高产、优质、高效,又要培肥地力和保护环境,使土壤生产能力不断提高,促进农业生产持续发展。传统的和习惯的施肥方式,造成了肥料浪费极大,利用率较低,影响农作物的产量和质量,更重要的是施肥过量,增加了农业生产成本,造成了环境污染,降 To continue the development of agricultural production, we must implement a scientific system of fertilization. In modern agricultural production, fertilization not only guarantees high yield, good quality and high efficiency of crops, but also fertilizes soil fertility and protects the environment so as to improve soil productivity and promote the sustainable development of agricultural production. The traditional and customary modes of fertilization result in great waste of fertilizers, low utilization rate, impact on the yield and quality of crops, and more importantly, excessive fertilization, increased agricultural production costs, environmental pollution,
