| 摘 要： | 以新陆早13号为材料,研究了调控技术对新疆棉花干物质积累和养分吸收的影响,结果表明:在水肥及化控总量不变的前提下运用调控技术增加了各生育期棉株地上部分干物质积累量、养分吸收量和分配率,在营养生长时期提高了干物质和养分在营养器官中的分配,在生殖生长时期提高了干物质和养分在生殖器官中的分配;调控技术还进一步提高了棉株干物质积累与养分吸收的相关性.

| Abstract: | The cotton variety Xinluzao 13 was used to study the effect of accomodable measures on dry matter accumulation and nutrition uptake in cotton plants.The result indicated that dry matters , nutrition uptake , nutrition distribution in the organs of cotton plants overground were increased by using accomodable measures on condition that the whole quantity of irrigation , fertilizer and DPC unchanged. Dry matter accumulation and nutrition distribution were increased in the nutrient organs during nutrient growth period and in the procreation organs during procreation development.The correlation of dry matters and nutrition uptake was improved also. |
