摘要
在大力提高旱地小麦产量的同时,必须从品种与栽培两个方面确保籽粒蛋白质等有较高水平,防止单纯追求产量而降低品种籽粒品质的倾向。品种肥力播期试验、品种播期播量试验、品种茬口肥力试验与品种防雨棚池栽试验证明,肥力、茬口和品种对品种蛋白质含量与蛋白质产量有明显的影响。同一品种在施肥量相同时,改善水分条件可以提高籽粒产量,提高对氮素的吸收量,提高蛋白质产量,而不能提高籽粒蛋白质含量。研究结果有利于正确选用旱地小麦品种和制定夺取高产优质的栽培措施。
While improving the yield of dryland wheat on a large scale,high prote-in conten in grain should be ensured from the varieties and cultivationtechniques.The tendency only to seek for high yield and neglet grain qualityof wheat varieties must be avoided.The trials of wheat varieties,soil fertilityseeding date,variety seeding date and rate,previous crop soil fertility,andthose of varieties cultivated in pools of rainproof tent turned out that soilfertility,previous crops and varieties had an apparent impact upon proteincontents and production of varieties.In the ease of same amount of fertilizerapplication to the same varieties,improving moisture condition can improvegrain yields aed N uptakes by wheat plants and raise protein production butnot raise the protein contents in grains.Research results are favourable to workout the cultivation measures to obtain high yields with fine qualities.
