Abstract

This invention discloses a special compound fertilizer for Ziziphus jujube. The special compound fertilizer has reasonable N / P / K ratio, and is enriched with organic matters and trace elements such as Na, Fe and Cu that are needed by Ziziphus jujube growth. The special compound fertilizer can improve the productivity and quality of Ziziphus jujube, and avoid insufficiency or waste of fertilizer.

Description

Technical field: [0001] The invention belongs to the category of fertilizers. Background technique [0002] At present, when fruit farmers fertilize winter jujube trees, some of them mix several elemental fertilizers together according to their feelings, and some use ordinary compound fertilizers. The ratio of nitrogen, phosphorus and potassium elements required for the growth of winter jujube trees and winter jujubes is imbalanced, resulting in low fruit setting rate, reduced fruit quality, poor palatability, leggy trunks, serious pests and diseases, and waste of fertilizers. Contents of the invention [0003] The purpose of the present invention is to provide a special compound fertilizer for jujube tree, the content of nitrogen, phosphorus and potassium in this fertilizer is suitable for the growth and development of jujube tree and jujube, and can give full play to the effectiveness of each element; Required organic matter and trace elements. Applying this special co...
