水稻旱育稀植技术主要是构架于水稻自身旱育秧特点和栽种密度合理化配合下的一种高产体系,能够大量节约水资源、人力资源、肥料和田地面积,并使得产量大幅度上升。结合本地实验及实践经验,就水稻旱育稀植技术中关键步骤进行分析,使云南省昌宁县水稻旱育稀植技术得到更好应用,提高水稻生产潜力,实现水稻增产增收的目的。 Rice is a high-yielding system mainly characterized by its own characteristics of dry seedling cultivation and planting density. It can save a lot of water resources, human resources, fertilizers and land area and make the yield increase significantly. Based on the local experiments and practical experience, the key steps in the technology of rice planting in dry cultivation and nursery are analyzed. The results show that the technology of rice dry-planting and planting in Changning County of Yunnan Province can be better applied, and the potential of rice production can be improved and the yield of rice can be increased.
