在旱育抛秧条件下，对钾肥的施用进行了研究，结果表明：钾肥施用量与土壤速效钾含量、水稻产量具有相关性，施用钾肥能有效提高水稻产量。每公顷施用150kgK2O，其中20％基施，80％追施效果最好。
Under the conditions of drought and throwing seedling, the application of potash fertilizer was studied. The results showed that there was a correlation between the potash fertilizer application rate and available potassium content and rice yield. Potash fertilizer application could effectively increase the yield of rice. Application of 150kgK2O per hectare, of which 20% based facilities, 80% top dressing effect best.
