磷矿粉属难溶性迟效磷肥,一般不易被作物很快吸收利用。为了充分发挥磷矿粉的增产作用,去年春、秋两季,我社搞了油菜施磷矿粉试验,获得了明显的增产效果。我社石砬子科技队在4月24日春播的门源油菜田上进行了磷肥试验,亩施磷矿粉160斤、120斤、80斤和过磷酸钙40斤等4种处理,油菜籽亩产分别为217.4斤、215斤、198.6斤 Phosphate rock powder is a poorly soluble late phosphate, generally not easily absorbed by crops quickly. In order to give full play to the role of phosphate rock production increase, last spring and autumn two quarters, we engage in rape phosphate rock application test, access to a significant yield increase. I Shijiazui Science and Technology team in the spring of April 24 broadcast of the source of Rape field trials phosphate fertilizer, Mushu phosphate rock powder 160 kg, 120 kg, 80 kg and 40 kg of superphosphate treatment, rapeseed yield per mu Respectively, 217.4 pounds, 215 pounds, 198.6 pounds
