1.柑桔大量的研究结果表明,钾对提高柑桔商品产量和品质因素有重要影响.这些因素包括果个大小、果皮厚度、质地、着色、糖酸比、可溶性固形物及Vc 含量.Cohen(1976)总结了钾素对果实发育及品质的影响:(1)使果个增大,尤其在土壤含钾量较低条件下;(2)增加果实着色;(3)改良了果皮厚度和果面粗糙度,但柠檬例外;(4)果个虽增大,果汁总量有所减少,但柠檬例外;(5)对可溶性固形物含量有抑制作用;(6)增加了果汁含酸量;(7)降低了糖酸比;(8)增
A large number of citrus research results show that potassium has an important impact on improving the yield and quality of citrus products.These factors include the size of the fruit, the thickness of the peel, texture, coloring, sugar-acid ratio, soluble solids and Vc content.Cohen (1976) summarized the effects of potassium on fruit development and quality: (1) increased fruit size, especially at lower potassium levels in the soil; (2) increased fruit coloration; (3) improved peel thickness and Fruit surface roughness, but the exception of lemon; (4) if the fruit increases, the total amount of juice decreased, but the lemon exception; (5) the soluble solids content inhibition; (6) increased juice acid content ; (7) reduce the sugar to acid ratio; (8) increase
