近两年,我们使用广西梧州市第二化工厂生产的“增产灵”对水稻进行了叶面喷施试验,取得明显的增产效果。试验结果,早稻“汕优4号”于始穗期叶面喷施(每亩2克兑水100斤),较不喷施的对照区,折合亩增稻谷49.7斤;较喷施20PPM的“九二○”多增稻谷20.8斤。晚稻“早广二”于始穗期结合防治三化螟叶面喷施,比不喷施的对照区,亩增稻谷50斤。此外,利用“增产灵”和“九二○”,“增产灵”和尿素,“九二○与尿素”混合的三种处理也都有增产作用,尤以“增灵产”(2克/亩)十“九二○”(20PPM)
The past two years, we use the second chemical plant in Wuzhou, Guangxi production by the “Zengling” of rice foliar spray test, and achieved significant increase yield. The results showed that the early rice “Shanyou 4” was sprayed on the foliage at the beginning of heading stage (100 kg per mu for 2 g / d), compared with 49.7 kg for no-spraying control. Compared with 20 PPM for spraying “ September 20 ”more by 20.8 kg of rice. Late rice “as early as two wide” in the beginning of the spike combined with the prevention and treatment of the yellow rice borer spraying, non-spraying control area, mu by 50 kg of rice. In addition, the use of “Zeng Ling” and “920”, “Zeng Ling” and urea, “nine two and urea,” the three kinds of treatment also have the effect of increasing production, Mu) Ten “nine two ○” (20PPM)
