关中主产棉区,主要以棉田作为小麦的良好前茬。由于棉花晚熟不能尽早拔杆腾地,影响小麦适时、精细播种,致使小麦苗期生长发育不壮,是限制小麦单产进一步提高的因素之一。为了解决大灌区粮棉生产中的恶性循环,为小麦夺高产创造良好条件。采用化学药剂催熟是解决棉花晚熟的一个新途径。1976年在泾阳县先锋大队科研站试用乙基磺原酸钠作棉花的脱叶催熟试验,取得一定效果。现将试验结果初报于后,供参考。
Main Guanzhong cotton area, mainly cotton as a good front crop of wheat. As late maturity of cotton can not pull pole as soon as possible, affecting wheat timely and fine sowing, resulting in wheat seedling growth and development is not strong, is to limit further increase in wheat yield one of the factors. In order to solve the vicious cycle of grain and cotton production in the large irrigation areas, creating favorable conditions for winning the high yield of wheat. The use of chemical ripening is a new solution to cotton late maturity. In 1976, Pioneer Brigade Jingyang Pilot Station trial of sodium ethyl sulfate as cotton leaves defoliation ripening test, and achieved some results. Now the first test results reported later, for reference.
