doi:10.3321/j.issn:1000-7091.2000.02.023

Abstract

Abstract: The cause of wheat grain weight reduction was analysed in 1998 by test and investigation. The results showed that anomalous weather conditions,harm of wheat aphid, poor comprehensive resistance of varieties and perfunctory cultivated management resulted in the wheat grain weight reduction by a large margin enriching soil fertility,selecting wheat variety with good comprehensive resistance, emphasizing apply fertilizer and irrigat ion at middle and later period,strengthening prevention and cure of plant diseases and controlling pests and so on were the strategic measure to ensure gettinghigh and stable grain weight and achieve increasing both wheat production and income.

Key words: Wheat, Grain weight, Comprehensive resistance, Green withering after a rain
