本文论述了从卤水中提取的钾镁硫(KMgS)复肥对甘蔗产量和品质的影响。结果表明,发育于硅质岩的酸性硅质砂壤土,其K、Mg、S含量均潜在不足,施用KMgS复肥对甘蔗有显着的增产效果,蔗茎产量达102.3t/hm2,比光施NP增产57.9%,比NP+KCl增产11%,且能改善甘蔗品质,使蔗糖分含量增加,还原糖含量降低,从而提高浸出糖的比例,经济效益显着。
This article discusses the effects of potassium, magnesium and sulfur (KMgS) compound fertilizers extracted from brine on sugar cane yield and quality. The results showed that the content of K, Mg and S in the acidic siliceous sandy loam which developed in chert is not enough. The application of KMgS compound fertilizer has a significant effect on the yield increase of sugarcane. The yield of sugarcane is 102.3t / hm2, The yield of NP was increased by 57.9% and 11% higher than that of NP + KCl, and the quality of sugarcane could be improved, the content of sucrose and the content of reducing sugar were reduced, and the ratio of leaching sugar was increased.
