Special fertilizer for longan tree and preparation method thereof

Abstract

The invention belongs to the technical field of a plant fertilizer, and particularly relates to a special fertilizer for a longan tree and a preparation method thereof. The special fertilizer is prepared by adopting the following raw materials in parts by weight: 35 to 40 parts of excrement of livestock, 25 to 30 parts of starch slag, 20 to 25 parts of mildew feed, 10 to 15 parts of cotton seed meal, 10 to 15 parts of edible mushroom dregs, 5 to 10 parts of humic acid, 155 to 175 parts of urea, 160 to 180 parts of potassium chloride, 50 to 70 parts of potassium magnesium fertilizer, 90 to 100 parts of calcium superphosphate, 10 to 15 parts of lignin, 7 to 9 parts of amino acid chelated copper and boron, 7 to 9 parts of cane sugar complexed manganese and calcium, 3 to 5 parts of diaminoferric xanthohumate and 4 to 6 parts of lignin zinc sulfonate. The special fertilizer is comprehensive in nutrition and stable and lasting in fertilizer efficiency; when the prepared fertilizer is used for fertilizing the longan tree, the nutrition requirement of the longan tree can be met, the growth speed of the longan tree can be increased, the yield and quality of longan can be improved, the characteristics of the soil can be improved, the formation of a soil cluster structure can be promoted, the soil is loosened, the soil structure is improved, the soil fertility is improved, and the environmental protection value and economic benefit are remarkable.

Description

technical field [0001] The invention relates to a special fertilizer, in particular to a special fertilizer for longan trees and a preparation method thereof, belonging to the technical field of plant fertilizers. Background technique [0002] Longan, (Latin scientific name: Dimocarpus longan Lour. ) is a Sapinaceae plant, also known as longan, puzzle, evergreen tree, tall tree, longan is rich in nutrition, fresh fruit juice is sweet, fragrant, can be eaten raw, can be processed into dried products or canned food, longan meat Rich in glucose, sucrose and protein, etc., the iron content is also relatively high, which can increase heat energy and supplement nutrition at the same time, promote the regeneration of hemoglobin, so as to achieve the effect of blood enrichment; longan meat not only has a tonic effect on the whole body, but also has a beneficial effect on brain cells. Especially effective, it can enhance memory and eliminate fatigue. Dried fruit pulp has the functio...

Problems solved by technology

[0005] At present, there are many types of fertilizers used for longan planting, and most of the fertilizers for longan are purchased from the market. However, most of the existing longan special fertilizers are chemical fertilizers. Although they can meet the growth needs of longan in a short period of time, the fertilizer efficiency The duration is short, and the absorption rate of longan is also low. Long-term use will damage the soil aggregate structure, easily cause soil compaction, soil hardening, and severely damage the soil, thereby affecting the growth of longan and promoting the growth of longan. It is not obvious, but the application of chemical fertilizers is heavy on nitrogen and light on phosphorus and potassium, ignoring the supplement of medium and trace elements such as calcium and magnesium, resulting in an imbalance in the proportion of organic and inorganic fertilizers, an imbalance in the ratio of nitrogen, phosphorus and potassium, insufficient medium and trace elements, and low effectiveness , affecting the quality and fruit setting rate of longan
