我区小麦高产面积约占麦播面积的20%,突出问题是产量高而不稳.为摸清高产小麦的营养特点,我们从1977至1980年,连续三年进行了不同施肥水平的田间试验,同时对土壤和植株进行诊断分析,研究高产小麦的营养特点和诊断指标,取得了较明确的结果.经1981年在所内进一步试验,应用此研究结果进行诊断施 The area with high yield of wheat accounts for about 20% of the area of ​​wheat sowing, and the outstanding problem is the high and unsteady yield.In order to find out the nutritional characteristics of high-yielding wheat, we conducted field trials at different fertilization levels for three consecutive years from 1977 to 1980 , At the same time on the soil and plant diagnosis and analysis of high-yield wheat nutrition characteristics and diagnostic indicators, and achieved a more clear result.After further tests in 1981, the application of this study to diagnose Shi
