Example Embodiment

[0016] In the first embodiment, it is often said that cherries are delicious and difficult to plant. We select cherries as the fertilization object. Early-ripening small cherries, the time from planting seedlings to fruiting is three years. Theoretically, the compound fertilizer of the present invention can provide plants with balanced, comprehensive, and lasting various nutrients, and can promote root development, improve plant disease resistance, and ultimately improve yield and product quality. Overcome the current unbalanced release rate of organic fertilizer defects.

[0017] Control experiment: Four plots of field for experiment were selected in Jishan County, Yuncheng City, Shanxi Province, each with about 20 acres and 200-210 cherry trees per acre. Each experimental field was divided into AB area, and the control group was treated with ordinary NPK organic fertilizer.

[0018] The test plot used the organic fertilizer described in the present invention, and the compound f...

[0022] Example 2: Apple is a kind of fruit cultivated in a wide area in my country, and it is a kind of fruit that people love most.

[0023] After the apples are planted, they begin to bear fruit in 2-3 years. The flowering period of apple trees is generally concentrated in April to May. The period of fruit growth is 90-133 days for mid-ripening varieties. The management of soil, fertilizer and water in the orchard is the basis for increasing the production of fruit trees and the center of comprehensive management. During the growth and development of fruit trees, it is necessary to constantly absorb water, nutrients and a part of air from the soil to ensure the normal growth and development of fruit trees. To build orchards in hilly areas, it is necessary to give full play to the favorable conditions of sufficient sunlight to overcome the thin soil. , With the disadvantages of less water and low fertility, the use of the group advantage of dense planting to achieve early frui...

[0030] Example 3: my country is one of the origin centers of citrus in the world. It has a cultivation history of more than 4,000 years. Its planting area has reached 2.9 billion mu, with a total output of 19.41 million tons, ranking first in the world in terms of area and total output. However, with the development of my country's citrus industry, many problems have been exposed, such as few good varieties, irrational variety structure, low yield, poor product quality, and low added value of products. The main reason for the few good varieties and the unreasonable variety structure is breeding problems; while the main reasons for low yield and poor product quality are cultivation problems, especially fertilization problems; the main reason for the low added value of products is insufficient deep processing of citrus products, and direct It is closely related to poor product quality. How to improve the quality of citrus fertilizer, which will not harden the soil and cause chemi...

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%,...
