目前,九二0较多的应用在农、林生产上,大多取得良好效果,但也有施用方法不当,效果不明显,甚至起反作用。九二0为无色结晶粉末。它不溶于水,而溶于醇类、丙酮、冰醋酸和 PH6.2的磷酸缓冲液中。在较低的温度和酸性条件下相对稳定,遇碱便中和失效。为合理施用九二0,现介绍常见用途与配制方法。一、九二O常见用途。1、在芹菜采收前半个月,每隔5天,用35-50ppm 九二0溶液喷一次。在菠菜5-6片叶时,用20ppm 九二0溶液喷一次。在苋菜6-7片叶
At present, the application of 92 more is mostly applied to agriculture and forestry, and most of them have achieved good results, but there are also some improper methods of application with insignificant effects and even counterproductive effects. September 20 is a colorless crystalline powder. It is insoluble in water, but soluble in alcoholic, acetone, glacial acetic acid and PH6.2 phosphate buffer. Relatively stable at lower temperatures and acidic conditions, the case of alkaline neutralization failure. To rationalize the use of 9280, we now introduce common uses and formulation methods. One, nine two O common use. 1, half a month before celery harvest, every 5 days, with 35-50ppm nine two 0 spray solution once. 5-6 leaves in spinach, with 20ppm nine hundred twenty-one spray solution. 6-7 leaves in amaranth
