摘要
本文研究了钾肥及不同形态的镁、硫肥配施对沙田柚的营养生长、柚果产量、品质及效益的影响,结果表明:施镁可大大减轻沙田柚叶片的缺镁症状;在土壤含钾、硫较丰富,镁含量中等的情况下,施用镁、硫肥配施仍然有较好的增产、增效作用,在一定程度上改善了柚果品质;配施碳酸镁及硫磺的产量和经济效益优于硫钾镁肥。
The influences of K and different forms of Mg, S combination application on vegetative growth, fruit yield, fruit quality and plantation profits of Shatian pumelo were studied The results showed that: Mg application considerable alleviated Mgdeficient symptom on leaf of Shatian pumelo; while soil in the orchard contained rich K and S and medium Mg, yield and plantation profits of Shatian pumelo still markedly increased by combination of Mg and S, and fruit's quality was improved as well However, combination of MgCO3 and sulfur did better than SulPoMag on fruit yield and plantation profits
