用~(32)P研究了鄂沙28、鄂光棉、泗棉1号、河南79、7010、徐州142六个棉花品种的根系对磷的吸收结果是,苗期鄂光棉磷的吸收量占居首位,徐州142居第二位,泗棉1号、河南79、7010比较接近,鄂沙28最差。现蕾后鄂沙28磷的吸收量迅速增加。到花期徐州142居首位,鄂沙28已跃居第二位,鄂光棉则从首位退居到第三位。其它三个品种仍较接近。
The results of phosphorus uptake by the roots of six cotton cultivars (E 28, E Guangmian, Simian 1, Henan 79,7010, Xuzhou 142) were studied by ~ (32) P, Occupy the first place, Xuzhou 142 second place, Simian 1, Henan 79,7010 closer, E 28 worse. After the bud, the absorption of 28 Phosphorus increased rapidly. 142 in the first place in flowering Xuzhou, E 28 has leapt to the second place, E Guang cotton from the first place to retire to third place. The other three varieties are still close.
