摘要: 谷子育苗移栽的栽培方式(栽谷)是农民的创造.栽谷由于育苗旱生,移栽断根,湿栽旱管,地下部和地上部形成旱生结构,根系分支增多,根层增加,活力增强,致使个体后期叶面积加大8.6~19.3%,厚度增加10~60%,改善了冠层结构,提高了群体的光能利用率与干物质积累,增产34~48%.

Abstract: The cultivating seedling and transplanting of millet is a creation of farmers, Because the millet seedlings are grown in drought condition, the roots are liable to be cut when the plants are transplanted,and the plants are cultivated under the drought condition, the aerial and subterraneous parts of the plants produce a xerophytic feature, In this cultivating form the millet root system is well developed and grows more vigourous, the leaf area of plant in later period increases by 8,6-19.3%,leaf thickness increa-ses by 10-60%,and the top structure is improved, So the utilized coef-ficient of light and the accumulation of dry matter of whole population are increased, and the yield is raised by 38-48%。
