绿鑫源土壤调理剂在水稻上的应用

Application of Lyuxinyuan Soil Conditioner on Rice

通过在酸性缺镁的水稻田里使用不同量的土壤调理剂,验证绿鑫源土壤调理剂在水稻田的应用效果。结果表明:每0.067 hm^(2)水稻田分别施用40 kg、50 kg、60 kg土壤调理剂,均能提高水稻产量,产投比分别为2.00、2.88、和2.57;提高了土壤pH值,改善了水稻植株的镁素营养,有效防治了缺镁黄叶症,提高了产量。

The application effect of Lyuxinyuan soil conditioner in paddy field was verified by setting different dosage of soil conditioner in acidic magnesium deficient paddy field.The results showed that applying 40 kg soil conditioner,50 kg soil conditioner and60 kg soil conditioner per 0.067 hm^(2) paddy field could increase rice yield,with yield/input ratios of 2.00,2.88 and 2.57,respectively.The application of soil conditioner can effectively increase soil pH value,improve the magnesium nutrition of rice plants,effectively prevent the occurrence of magnesium deficiency yellow leaf disease and increase the yield.
