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%.
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 thichness increases by 10-60%, and the top structure is improved. So the utilized coefficient of light and the accumulation of dry matter of whole population are increased, and the yield is raised by 38-48%.
