冬小麦是我国北方高产稳产的粮食作物之一,进一步扩大冬小麦种植面积,提高小麦单位面积产量,降低生产成本,实现“高产、稳产、低成本”,对促进农业大上具有十分重要的意义。本实验的目的是总结盐碱地上广大贫下中农对小麦高产实践的经验;研究小麦高产中由于营养失调而产生不同苗情的诊断方法;确定盐碱地上小麦亩产600—800斤高产栽培的促控指标和诊断技术;为小麦高产、稳产、低成本,提供群众能掌握和运用的田间诊断技术,为四级农业科学实验网开展科学种
Winter wheat is one of the grain crops with high and stable yield in northern China. It is very important to promote the agricultural development by further expanding the planting area of winter wheat, increasing the yield per unit area of wheat, reducing the production cost and realizing “high yield, stable yield and low cost”. The purpose of this experiment is to summarize the experience of high and low yielding middle peasants on the high yielding practice of wheat in saline-alkali soil; to study the diagnosis method of different seedling conditions due to malnutrition in high-yielding wheat; to determine the promotion and control index of high-yielding cultivation of 600-800 kg per mu And diagnostic technology; for the wheat high yield, stable yield, low cost, to provide the masses can grasp and use of field diagnostic techniques for four Agricultural Science Experimental Network to carry out scientific species
