钙镁磷肥是以含磷为主的多元素肥料,呈微碱性,不溶于水,而溶于弱酸。它含有效磷14—20％,镁10—15％,钙25—30％,硅25—30％,可为植物提供磷、钙、镁、硅等多种元素,有利于提高植物的产量和抗逆性。据初步统计,近三年我省苹果树施用钙镁磷肥达两万余吨,施用苹果树400万株(占全省结果树的14％),累计增产两亿公斤,增加纯收益84万元。
Calcium magnesium phosphate is based on phosphorus-based multi-element fertilizer, was slightly alkaline, insoluble in water, soluble in weak acid. It contains 14-20% of available phosphorus, 10-15% of magnesium, 25-30% of calcium and 25-30% of silicon, and can provide phosphorus, calcium, magnesium and silicon for plants and the like, Stress resistance. According to preliminary statistics, in the past three years, the apple trees in our province have used more than 20,000 tons of calcium magnesium phosphate fertilizer and 4 million apple tree species (accounting for 14% of the province’s results tree), with a total increase of 200 million kg and an increase of net profit of 840,000 yuan .
