通过小麦钾肥试验,探讨了钾肥在小麦上的增产效果及其经济合理施用量。结果表明.钾肥能提高小麦有效穗数和千粒重,施钾比不施钾增产17.0％ 44.1％:小麦最高产量旋施钾肥量为硫酸钾18.87公斤/亩,最佳经济效益施钾肥量为硫酸钾17.05公斤/亩。
Through the experiment of wheat potassium fertilizer, the effect of potassium fertilizer on wheat and its economic and reasonable application were discussed. The results showed that potash fertilizer can increase the effective panicle number and 1000-grain weight of wheat, and increase the yield of potassium by 17.0% and 44.1%, respectively, compared with no potassium application. The maximum yield of wheat was 18.87 kg potassium potassium per kg of potassium sulfate and the best economic benefit was potassium sulfate 17.05 kg / mu.
