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 need to fertilize many times to meet their nutritional needs, resulting in a serious waste of fertilizers

[0023] A fertilizer for jujube trees and a preparation method thereof, comprising the following steps:

[0024] Step 1. Weigh the raw materials of each component according to the proportion of the formula, add water to the weighed sunflower pan powder and mix it with water, and when the material is grasped by hand, no water dripping is the limit, and it is piled up and fermented into organic fertilizer;

[0025] Step 2: Stir urea and fertilizer additives for 15-20 minutes according to the formula ratio, add bentonite and stir for 20-30 minutes, then transfer to a mixer;

[0026] Step 3, fully mix the materials stirred in step 2 with potassium dihydrogen phosphate, potassium nitrate and other materials in the formula, then fully mix with the fermented sunflower pan powder, then transfer to the fertilizer granulator to granulate and form, and then Spray an appropriate amount of paraffin on the pellets.

[0027] The preparation method of fertilizer additive:

Abstract

The invention discloses a fertilizer for jujube trees and a preparation method of the fertilizer. The fertilizer is prepared from the following raw material components in parts by weight: 60-80 parts of monopotassium phosphate, 30-40 parts of potassium dihydrogen phosphate, 30-50 parts of urea, 40-60 parts of sunflower head powder, 1-2 parts of ferrous sulfate, 6-10 parts of chitosan, 10-15 parts of bentonite and 10-15 parts of a fertilizer additive. According to the jujube tree fertilizer disclosed by the invention, organic components and inorganic fertilizers are mixed, meanwhile, the fertilizer additive is added, the nutrition proportion is reasonable and comprehensive, and the slow-release fertilizer is prepared by adopting a slow-release fertilizer preparation method during preparation.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a fertilizer for jujube trees and a preparation method thereof. Background technique [0002] 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 diseases. These fertilizers dissolve quickly in the soil, and the fertilizer effect time Short, in the annual growth cycle of juj...
