脱叶剂

脱叶剂对棉叶中植物生长调节剂含量的影响及脱叶机理初步研究

The Preliminary Study on Effect of the Content of Plant Growth Regulator in Cotton Tissue with Defoliant and Its Mechanism

20世纪，氯酸钠曾被作为非选择性除草剂和脱叶剂在农业生产中大量施用。

Last century , sodium chlorate was used to be as non-selective contact herbicides , defoliant and even soil sterilant in agricultural history .

驻韩美军说，1970年代有其他脱叶剂埋在营地内，但在几年内就挖出并移走了。

The USFK says that during the late seventies barrels of other defoliants were buried on base , but were dug up within a few years and removed .

对4种棉花脱叶剂进行了脱叶剂与乙烯利混配处理棉花试验，研究脱叶剂不同处理脱叶效果及其对棉花衣分、纤维长度、产量的影响。

On the basis of4 kinds of cotton disleave agent , the test for disleave agent and the disleave agent mixed with ethrel to treat the cotton was conducted .

喷施脱叶剂的最佳温度为目平均温度在18～25℃，最佳喷药期9月10～15日，吐絮率达到40%时即可喷施。

The optimum temperature of spraying the mixture defoliants was the 18 ~ 25 ℃ at the daily average temperature , the best spraying time is on September 10 ~ 15th , The spraying can be practiced at the time which the ruptured cotton wool rate achieves 40 % .

采用人工调控脱叶有利于机械采收，但是脱叶剂脱叶效果将影响机械采收。

It will be useful for picking of machine with manpower controlling , but the impact of defoliant will influence the machine picking .
