为避免碳酸氨铵灼伤绿萍,我们对养用绿萍的前季稻,采用了以下三种施肥方法:一、追肥改作中层肥。把作追肥用的30斤碳酸氢铵提前到翻土上水后,均匀撒施,再用拖拉机旋耕犁翻耖作为中层肥,同样可起到追肥促发棵的作用。二、返青肥改为面肥。把第一次加工(移栽后5天左右)施用的返青肥,改为移栽前作面肥施。三、根据苗情补施追肥时,做到随施随加工。在施碳酸氢铵作追肥时,碳酸氢铵必须与细泥土混合成
Ammonium carbonate to prevent burn burn Greenpea, we use green rice paddy before the season, using the following three kinds of fertilization methods: First, the top dressing into fertilizer. Topdressing 30 kg of ammonium bicarbonate for topdressing is applied in advance to pouring soil into the water and evenly spread. Then a tractor is used to turn the plow to turn over the middle layer of fertilizer. Second, return to green manure changed to fat. The first processing (about 5 days after transplanting) applied green turning fat, replaced by surface fertilizer before transplanting. Third, according to Miao replenishment top dressing, so with the processing with Shi. In the application of ammonium bicarbonate for top dressing, ammonium bicarbonate must be mixed with fine soil
