磷酸二氢钾是一种高效复合磷钾肥。有94％的养分能为作物直接吸收,特别适宜叶面喷施。一般在谷类作物上每亩喷施3—4两,粮食产量可增加10—30％。我们自制土法生产的磷酸二氢钾,于1978年在徐塘公社农科站麦地喷施,收到良好效果。一、土法生产取过筛的新鲜草木灰5斤,加水25斤浸泡,另取过磷酸钙2斤,压细过筛,徐徐撒入浸泡液中,边撒边
Potassium dihydrogen phosphate is an efficient compound of phosphorus and potassium fertilizer. 94% of the nutrients can be directly absorbed by the crop, especially suitable for foliar application. Sprayed 3-4 grains per acre on cereals generally, grain yield can increase 10-30%. Our self-made indigenous potassium phosphate monobasic, sprayed in 1978, Xu Tong commune agrochemical farm spraying, received good results. First, the indigenous production of sift through the fresh grass ash 5 pounds, add 25 kg of water soaking, and the other to take 2 kg of superphosphate, the pressure fine sieve, slowly scattered into the soaking liquid, Caesar edge
