If we want to increase the economic benefits of grapefruit and citrus, we need to increase their sugar content. Now, teach you several ways to increase sugar content. First, the use of sodium nitrophenolate can increase the size of the fruit. Before and after the flowering of the citrus, we can use the 1.8-fold solution of sodium nitrophenolate 1500-2000 times to spray the entire plant. Avoid crops and fruit drop phenomenon, but also to make the fruit bigger. Secondly, 4-8 weeks before picking grapefruit and citrus, 120 mg/L to 240 mg/L fruit sweetener solution can be applied, which will reduce the acid-to-sugar ratio. Thirdly, we can choose to apply one percent of the zeatin solution to spray during citrus flowering, which will significantly increase citrus yield. Fourth, in the period when the citrus has just entered the autumn shoot (result mother tree), a 1000 mg/L to 1600 mg/L paclobutrazol solution is sprayed on the foliage to control the elongation of the shoot and promote bud differentiation. Increase crop yields. Fifthly, after the citrus tree grows new shoots, a 5000-6000-fold 1.8% solution of sodium nitroprusside is applied. It takes about 2 to 3 times from about 20 days before flowering to before flowering. After the result, Spraying one or two times can also promote the germination and fertilization of the fruit trees and promote fruit and fruit hypertrophy. The continuous application can obviously enhance and restore the tree potential. In addition, it will also have a good promotion effect on the quality and taste of the product.
