Root-promoting and weeding date tree specially-used organic-inorganic composite fertilizer and preparation method thereof

Abstract

The invention provides a root-promoting and weeding date tree specially-used organic-inorganic composite fertilizer which includes following components, by weight, 50-60 parts of dried cow dung, 40-50 parts of wormcast, 20-30 parts of sunflower head powder, 8-10 parts of sugar residue, 10-20 parts of plant ash, 1-2 parts of a microbial fermentation inoculant, 5-8 parts of ammonium phosphate, 10-12 parts of urea, 10-15 parts of calcium superphosphate, 12-14 parts of potassium chloride, 0.2-0.5 parts of zinc sulfate, 0.8-1.0 part of ferrous sulfate, 0.001-0.004 parts of ammonium molybdate, 0.001 parts of ethephon, 10-15 parts of agriculturally-use rare earth, 5-8 parts of dicyandiamide, 0.1-0.3 parts of zinc thiazole and 10-15 parts of a fertilizer additive. The date tree specially-used organic-inorganic composite fertilizer can promote growth of roots and meanwhile can inhibit growth of weeds and is reasonable in nutrition proportion. The organic components and the inorganic components are combined for improving soil fertility. With the addition of the weeding agent, weeds can be effectively controlled. The fertilizer can promote the roots of date trees to growth quickly and increases yield.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special organic-inorganic compound fertilizer for rooting and eradicating jujube trees and a preparation method thereof. Background technique [0002] Jujube is rich in nutrition, and it has been a good nutritional product for people to nourish since ancient times. Jujube has a long history of cultivation in my country. Reasonable fertilization is an important factor to increase jujube yield and improve jujube quality. At present, jujube trees are fertilized with urea, phosphate fertilizer and quick-acting compound fertilizer in addition to some organic fertilizers such as ring fertilizer and soil miscellaneous fertilizer. Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, l...

Problems solved by technology

Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, low fruit setting rate, and serious pests and diseases. These fertilizers dissolve quickly in the soil, and the fertilizer effect time short, in the annual growth cycle of jujube trees, multiple fertilizations are needed to meet their nutritional needs, resulting in serious waste of fertilizers. The invention provides a special organic-inorganic compound fertilizer for promoting weeding and eradication of jujube trees, with a reasonable nutrient ratio , One time fertilization can release nutrients slowly, and the fertilizer effect can maintain slow release
