Root system maintaining fertilizer for fruit trees

Abstract

The invention discloses root system maintaining fertilizer for fruit trees. The fertilizer is prepared from the following raw materials in parts by weight: 40 to 45 parts of brewer's grain, 4 to 5 parts of oyster shell pieces, 13 to 14 parts of tea seed cakes, 1 to 2 parts of EDTA (Ethylene Diamine Tetraacetic Acid) ferric sodium salt, 4 to 6 parts of sodium bicarbonate, 1.4 to 1.6 parts of crustacean amine, 3 to 4 parts of corn starch, 12 to 15 parts of chitosan, 0.2 to 0.3 part of potassium permanganate, 1.0 to 1.2 parts of manganese sulfate, 2.2 to 2.5 parts of acrylamide, 0.4 to 0.5 part of N,N'-methylene bisacrylamide, 1 to 2 parts of ammonium persulfate, 2 to 3 parts of zinc acetate, 0.2 to 0.3 part of yttrium nitrate, an appropriate amount of an absolute ethyl alcohol solution, and an appropriate amount of water. The fertilizer disclosed by the invention has adequate and balanced nutrients, and meets the requirement for a large quantity of nitrogen and phosphorus when the fruit trees grow; multiple soluble raw materials such as the EDTA ferric sodium salt, the crustacean amine and the like are used for coordinating with the thoroughly decomposed fermentation products of the tea seed cakes and the brewer's grain to improve the physicochemical environment around the root zones of the fruit trees very well; the fruit tree root system development is promoted; the fruit tee root system activity is improved; then, the tree body health is guaranteed; and the quality of fruits is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a root maintenance fertilizer for fruit trees. Background technique [0002] With the increasing level of modernization of agriculture, new organic fertilizers are gradually replacing ordinary chemical fertilizers and becoming important fertilizers in agricultural production. Organic fertilizers have many advantages such as complete nutrition, improved soil, and increased fertilizer utilization. However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effec...
