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.
