Embodiment 1

[0016] Embodiment 1, it is often said that cherries are delicious and difficult to plant, so we choose cherries as the fertilization object. Early-maturing small cherries, it takes three years from planting seedlings to fruiting. Theoretically, the compound fertilizer of the present invention can provide plants with balanced, comprehensive and long-lasting nutrients, promote root development, improve plant disease resistance, and ultimately improve yield and product quality. It overcomes the defect of unbalanced release rate of organic fertilizer at present.

[0017] Controlled experiment: In the cherry producing area of ​​Jishan County, Yuncheng City, Shanxi Province, four test fields were selected, each field was about 20 mu, and there were 200-210 cherry trees per mu. Each test field was divided into AB area, and the control group was applied with common nitrogen, phosphorus and potassium organic fertilizers.

[0018] What the test plot uses is the organic fertilizer that...

Embodiment 2

[0022] Embodiment 2, apple is a kind of fruit widely cultivated in my country, and it is a kind of fruit that people like most.

[0023] After the apples are planted, they start to bear fruit in 2-3 years. The flowering period of apple trees is generally concentrated in April-May. The fruit growth period is 90-133 days for mid-maturing varieties. The management of soil, fertilizer and water in orchards is the basis for increasing the production of fruit trees and the center of comprehensive management. In the process of fruit tree growth and development, it is necessary to constantly absorb water, nutrients and part of the air from the soil in order to ensure the normal growth and development of fruit trees. In the construction of orchards in hilly areas, it is necessary to give full play to the favorable conditions of sufficient light to overcome the thin soil. , less water, low fertility conditions, using the group advantage of close planting cultivation, to achieve early ...

Embodiment 3

[0030] Embodiment 3, my country is one of the origin centers of citrus in the world, with a cultivation history of more than 4,000 years, its planting area reaches 2.9 billion mu, and its total output reaches 19.41 million tons, ranking first in the world in both area and total output. However, while my country's citrus industry is developing, many problems have also been exposed, such as few good varieties, unreasonable variety structure, low per unit yield, poor product quality, and low product added value. The main reason for the few good varieties and unreasonable variety structure is the breeding problem; the main reason for the low yield and poor product quality is the cultivation problem, especially the fertilization problem; the main reason for the low added value of the product is that the deep processing of citrus products is not enough. It is closely related to poor product quality. How to improve the quality of citrus fertilizer, which will not compact the soil and...

Abstract

The invention relates to fertilizer, in particular to compound fertilizer balanced in releasing. According to the technical scheme, the compound fertilizer comprises organic fertilizer particles, wherein the compound fertilizer particles comprise compound fertilizer core materials and outer wrapping layers; the compound fertilizer core materials comprise 30% of urea, 30% of monoammonium phosphate, 30% of potassium chloride and 10% of potato starch; the compound fertilizer particles is formed by particles A, particles B, particles C and particles D according to a certain proportion. By the compound fertilizer, high seedling survival rate can be achieved, yield can be increased, soil hardening can be eliminated, and soil can be loosened.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound fertilizer with balanced release. Background technique [0002] Traditional slow-release compound fertilizers are only coated in a single layer, and their slow-release effect mainly depends on the outermost coating layer. The slow-release effect of the coating layer is mainly due to the slow disintegration or dissolution of the coating layer so that the internal organic fertilizer can be dissolved for a prolonged period of time. In the research, it was found that the dissolution rate has a great relationship with the thickness of the coating layer and the dissolution time. For example, a 2mm thick coating layer needs 30 days to completely dissolve. Judging from the element release effect of the compound fertilizer, the dissolved amount of organic fertilizer is only about 10-15% in 1-29 days, while on the 30th day it is only about 10-15%. The dissolution effect soared to more than 90%,...
