Sweetening method for Taiwan green jujube fruit

Abstract

The present invention provides a sweetening method for the fruit of Taiwan green jujube, and comprises the deep fertilizer application of Taiwan green jujube and the nutrient fluid spraying on the leaves. Through applying and spraying the magnesium fertilizer at the growth stage, applying and spraying the boric fertilizer during the period from the flowering stage to the fruit-picking stage, and spraying the nutrient fluid during the enlargement stage of the fruit, the present invention provides sufficient fertilizer and water for Taiwan green jujube, thereby reducing the leaf-falling phenomenon, guaranteeing sufficient photosynthesis, effectively improving the content of the soluble solid object in the fruit and greatly increasing the sweetness of the fruit; using pro-soil active biological bacteria or the humic acid, the fixed nutrient element in the soil can be renewable. Using the organic amino acid nutrient fluid fertilizer to spray the leaves, the sufficient supply of the organic matter is effectively maintained in the soil, thereby resolving the problem of improving the sweetness of Taiwan green jujube in the prior art, satisfying the requirement of the consumer and obviously increasing the economic benefit of the fruit garden.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and relates to a technology suitable for sweetening perennial fruit tree fruits on hillsides and flat lands, in particular to a method for sweetening the fruits of Taiwan jujube trees. Background technique [0002] At present, people's living standards are constantly improving. In daily life, the requirements for fruit quality are getting higher and higher, and the sweetness of fruit determines the quality of fruit to a large extent. In order to improve the sweetness of fruit trees and meet the needs of consumers, measures such as spraying amino acid solution or potassium dihydrogen phosphate solution on the leaves of Taiwan jujube trees are usually used to improve fruit sweetness. Although this method is somewhat effective, it is not effective. It is difficult to meet the actual needs of consumers. Contents of the invention [0003] The purpose of the present invention is to pr...
