Special fertilizer for jujube trees, and preparation method thereof

Abstract

The invention provides a special fertilizer for jujube trees. The special fertilizer comprises, by weight, 30-35 parts of bagasse, 20-30 parts of soybean straw, 10-20 parts of soybean pod shell, 8-10 parts of soybean curd residue, 30-40 parts of phosphate rock powder, 10-20 parts of bamboo powder, 1-2 parts of potassium dihydrogen phosphate, 1-2 parts of ammonium nitrate, 5-10 parts of animal fur, 1-2 parts of ammonium molybdate, 1-2 parts of sodium borate, 3-4 parts of ferrous sulfate, 1-2 parts of zinc sulfate, 8-10 parts of carboxymethylcellulose sodium, 8-15 parts of starch, and 10-15 parts of a fertilizer additive. The special fertilizer for jujube trees has the characteristics of comprehensive nutrition, reasonable ratio, and slow and controlled release. The above product can greatly improve the absorption utilization rate of nitrogen, phosphorus, potassium and various trace elements in soil, enables the nutrient utilization rate to be 20-35% higher than that of traditional chemical fertilizers, and is a new green environmentally-friendly fertilizer.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for jujube trees and a preparation method thereof. Background technique [0002] Jujube is rich in nutrition, and it has been a good nutritional product for people to nourish since ancient times. Jujube has a long history of cultivation in my country. Reasonable fertilization is an important factor to increase jujube yield and improve jujube quality. At present, jujube trees are fertilized with urea, phosphate fertilizer and quick-acting compound fertilizer in addition to some organic fertilizers such as ring fertilizer and soil miscellaneous fertilizer. Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, low fruit setting rate, and serious pests and diseas...

AI Technical Summary

Problems solved by technology

Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, low fruit setting rate, and serious pests and diseases. These fertilizers dissolve quickly in the soil, and the fertilizer effect time short, in the annual growth cycle of jujube trees, multiple fertilizations are needed to meet their nutritional needs, resulting in serious waste of fertilizers. The invention provides a special fertilizer for jujube trees, with reasonable nutrient ratios, and once fertilized, the nutrients can be released slowly, Fertilizer effect maintains slow release
