碳酸氢铵是弱碱性化肥,具有挥发性和腐蚀性,施用不当,既影响肥效,还会造成烧秧和死苗。根据我们试验,用碳酸氢铵“戽秧板”作底肥,或兑水泼浇作追肥,效果都好。“戽秧板”,即在秧田播种之前,先放干田水,每亩用30—40斤碳酸氢铵,掺和2—3侣的细土,充分拌和均匀后撒施在秧畦上,然后荡平畦面,使肥料埋进浅土层,最好用齿耙轻耘一次,再进行播种、塌谷。兑水泼浇作秧苗追肥的,每亩用碳酸氢铵15—20斤,每斤兑水60—100斤,经充分搅拌,使肥料全部溶化后进行泼浇或喷洒。为防
Ammonium bicarbonate is a weak alkaline fertilizer, volatile and corrosive, improper application, both affect fertilizer efficiency, but also cause burned seedlings and dead seedlings. According to our test, with ammonium bicarbonate “Sui Yang Ban” as a base fertilizer, or against the water pouring top dressing, the effect is good. “Sowing board”, that is sowing before sowing, first put dry field water, with 30-40 kg per mu of ammonium bicarbonate, mixed with 2-3 lobster fine soil, mix well and spread on the seedlings, and then Flattened noodles, so that fertilizer buried in shallow soil, it is best to use tooth harrow light once, and then sow, collapse of the valley. Sprinkle pouring water for seedlings topdressing, with ammonium bicarbonate 15-20 kg per acre, pound watered 60-100 kg, after full mixing, the fertilizer was melted after pouring or spraying. To prevent
