水稻侧深施肥一体化技术试验示范研究

Analysis on the Implementation of the Integrated Technology of Lateral Deep Fertilization in Rice

水稻生产过程中施肥一般在耙地前、缓苗期、生长期、出穗期分4次施肥,通常采用传统人工手撒浅表性施肥的方式,劳动强度大、作业效率低、肥料利用率低、污染环境。随着生产过程排灌水,含有肥料的水体会对环境造成严重的污染,而且大量化肥的应用,使耕地板结造成肥力、明显下降,解决土地板结和高效施肥、施药成为水稻生产过程中急需解决的难题。

In the process of rice production,4 times of fertilization are needed before harrowing,at slow seedling stage,growth stage and heading stage.The traditional manual method of superficial fertilization has the advantages of high labor intensity,low operation efficiency,low fertilizer utilization rate and environmental pollution.With the drainage and irrigation in the production process,the water body containing fertilizer will cause serious pollution to the environment,and the application of a large number of chemical fertilizers will significantly reduce the fertility of the cultivated floor.It is an urgent problem to solve the problem of land hardening,high-efficiency fertilization and application of chemicals in the rice production process.
