西郊农场碱性土水稻旱育苗示范研究旱育苗是水稻节水增产综合配套技术重要环节之一。农场曾先后３次由国内外水稻栽培专家进行过旱育苗试验，由于对碱性土旱育苗的特点掌握不够，立枯病、青枯病防治未能过关，无法大面积推广。本次研究目的在于解决常规育苗苗不壮，且占地多、 Demonstration of Alkaline Soil Dry Nursery Seedlings in West Suburb Farm Dry seedling nursery is one of the important links in the integrated supporting technology for water saving and yield increase of rice. The farm has successively conducted three experiments with rice seedlings at nurseries and rapeseed nurseries. Due to inadequate mastery of the characteristics of alkaline soil and drought nurseries, the prevention and control of blight and bacterial wilt failed to pass the scale and could not be popularized widely. The purpose of this study is to solve the problem that conventional seedling nursery is not strong,
