小麦耐盐机理及盐碱地高产栽培技术研究进展

ADVANCES IN MACHANISM OF THE SALT TOLERANT AND HIGH YIELDING CROPS CULTURE OF WHEAT

耐盐小麦抵抗盐胁迫是以渗透调节为主的多因素作用的结果，在渗透调节中甜菜碱起到十分重要的作用．为了适应盐胁迫耐盐小麦应该具有相应的结构特征．耐盐小麦生物学性状与形成产量的关系是耐盐小麦育种的理论基础，在生产实践中，选择优良耐盐品种结合覆膜技术使耐盐小麦各种生理指标都得到改善，获得了 ６６００公斤／公顷的高产量．鉴于甜菜碱的独特作用，如果经济成本允许应该考虑耐盐小麦田间甜菜碱施肥．

Salt tolerant wheat can tolerate the high salt is the result of many elements, one main of which is osmotic adjustment, and betaine is very important in osmotic adjustment. To adapt to a line soils, The wheat has the many corresponding structural. The relation between biological characters of salt tolerant wheat and its high yielding is the theoretical foundation in its breeding, Selecting the good salt tolerant wheat and utilizing plastic film mulching have improved many physiological in practice and have got the yielding of 6600 kg per hectare, If the production cost permitted, utilizing betaine in salt tolerant wheat cultivating because of the especial effect of betaine.
