Fruit tree organic and inorganic composite fertilizer and preparation method thereof

Abstract

The invention discloses a fruit tree organic and inorganic composite fertilizer. The fruit tree organic and inorganic composite fertilizer is prepared from the following ingredients in parts by weight: 50 to 70 parts of fermented biogas residue, 10 to 30 parts of kieselguhr, 30 to 55 parts of phosphorous sea bird fertilizers, 12 to 20 parts of ground phosphate rock, 20 to 30 parts of turf, 8 to 14parts of calcium cyanamide, 10 to 15 parts of bone powder, 12 to 25 parts of ammonium bicarbonate, 15 to 25 parts of potassium sulphate, 3 to 10 parts of plant enzymes, 5 to 15 parts of borax, 6 to 10 parts of ferrous sulfate, 4 to 8 parts of synergists, 4 to 8 parts of trace elements and 3 to 6 parts of microbial agents. The formula of the feed richly contains various nutrition substances required by the growth of the fruit trees; no hormone is added; non-toxicity, harmlessness and no pollution are realized; the functions of promoting the absorption utilization of the fruit tree root systemson the fertilizers and preventing and controlling the soil diseases can be achieved; meanwhile, various functions of enhancing the fruit tree cold resistance, drought resistance, salt and alkali resistance, insect resistance and the like can be realized; the fruit tree quality is improved; the fruit tree yield is fundamentally improved.

Description

technical field [0001] The invention relates to the field of fertilizers used in forestry production, in particular to an organic-inorganic compound fertilizer for fruit trees and a preparation method thereof. Background technique [0002] Usually bio-organic fertilizers are called microbial-organic compound fertilizers, and those combined with chemical fertilizers are also called bio-organic-inorganic compound fertilizers. In recent years, my country's fertilizer structure has undergone fundamental changes, and the proportion of organic fertilizers in total fertilizer consumption has dropped from 100% in 1949 to about 50% at present. The extensive application of chemical fertilizers has played a huge role in increasing production in the history of my country's agriculture. Existing fertilizers for fruit trees have a single function, which can only achieve the effect of medicine or fertilizer. When the medicine and fertilizer are applied at the same time, the amount of medi...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of fruit tree organic-inorganic compound fertilizer and preparation method thereof, wherein in the synergist, sodium p-nitrophenolate, ammonium chloride and phosphate rock powder, bone meal are mixed, can increase the solubility of phosphorus, improve fruit tree to The absorption of fertilizers solves the problem that fertilizers are difficult to be completely absorbed at present; at the same time, sodium naphthalene acetate in the synergist can promote growth, improve quality, promote the synthesis of chlorophyll in fruit trees, promote lush branches and leaves, and increase yields, while polyaspartic acid is effective on metals. Ions have a chelating effect. Polyaspartic acid with a certain molecular weight can enrich nitrogen, phosphorus, potassium and trace elements to supply plants, so that trees can use fertilizers more effectively. The mixed use of polyaspartic acid and sodium naphthalene acetate can make The peptide bond on the main chain of its structure is not easily broken by biodegradation, solves soil compaction, loosens soil, enhances the absorption of fertilizers and accumulation of dry matter by fruit trees, fundamentally promotes early maturity of crops, increases production, and improves product quality
