为提高柑桔果实的品质,增加糖度而采用覆盖、盆箱、高墩、温室、限制根域等多种栽培法,其原理都是对植物体进行干燥胁迫。 干燥胁迫提高果实糖度的主要原因:在叶果比一定,树体光合产物总量不增加的情况下,果实糖度的提高来源于以下两个方面:第一,果实内总糖量一定,果实越小,由于浓缩作用果汁糖度增加。地膜覆盖栽培就是使果实变小而提高果汁糖度的。第二,果实内部糖量的增加,有
In order to improve the quality of citrus fruits, increase the sugar content and cover, pots, high pier, greenhouse, limiting the root zone and other cultivation methods, the principle is to plant dry stress. Drying stress to increase the fruit sugar content of the main reasons: in the leaf ratio of certain, the total amount of photosynthetic products does not increase the case, the increase in the degree of sugar from the following two aspects: First, the total sugar content in the fruit, the more fruits Small, due to the concentration of fruit juice sugar increase. Film mulching cultivation is to make the fruit smaller and increase the sugar content of fruit juice. Second, there is an increase in the amount of sugar inside the fruit
