Efficient fruit tree compound fertilizer and preparation method thereof

Abstract

The invention discloses an efficient fruit tree compound fertilizer, which is characterized by being prepared from the following raw materials in parts by weight: 50 to 60 parts of active peat, 7 to 9 parts of zinc-ammonia complex fulvate, 70 to 80 parts of sodium dihydrogen phosphate, 3 to 5 parts of iron-ammonia complex fulvate, 150 to 170 parts of urea and 150 to 180 parts of potassium chloride. After the efficient fruit tree compound fertilizer is applied, the fruit setting rate quality is improved; the yield is high; the yield increasing effect is obvious; the economic benefit is improved by 30 percent.

Description

technical field [0001] The invention relates to a high-effect tree compound fertilizer, in particular to a special fertilizer suitable for pears, apples and grapes in southern China and a preparation method thereof, belonging to the technical field of plant fertilizers. Background technique [0002] At present, there are many types of fertilizers used for fruit trees, especially Southland pears, apples and grapes, and many of them are also chemical fertilizers. Although they can meet the needs of Southland pears, apples and grapes in a short period of time, but The duration of fertilizer effect is not long, and the absorption efficiency of fruit trees is not high. Long-term use of chemical fertilizers will also change the soil quality, which will easily cause soil compaction, soil hardening, and damage to the soil, thereby affecting the growth of Nanguo pear, apple trees and grapes; at the same time The chemical fertilizers used are insufficient to supplement the medium and ...

[0002] At present, there are many types of fertilizers used for fruit trees, especially Southland pears, apples and grapes, and many of them are also chemical fertilizers. Although they can meet the needs of Southland pears, apples and grapes in a short period of time, but The duration of fertilizer effect is not long, and the absorption efficiency of fruit trees is not high. Long-term use of chemical fertilizers will also change the soil quality, which will easily cause soil compaction, soil hardening, and damage to the soil, thereby affecting the growth of Nanguo pear, apple trees and grapes; at the same time The chemical fertilizers used are insufficient to supplement the secondary and trace elements such as calcium and magnesium in the soil, which affects the quality and fruit setting rate of Nanguo pears, apples and grapes
