Special compound fertilizer applied to Guanyang red dates and preparation method thereof

Abstract

The invention relates to the field of production of fertilizers and particularly relates to a special compound fertilizer applied to Guanyang red dates and a preparation method thereof. The fertilizer is prepared from decomposed livestock excrement, phosphogypsum, straw powder, soybean cake powder, methane residue, radix stemonae and biological strains. The invention also provides a preparation method of the fertilizer. When the prepared fertilizer is sprayed to the Guanyang red date trees, the requirements on nutrient elements of the Guanyang red dates in various growth stages can be met; the positive effect on the yield increase of the Guanyang red dates is achieved; meanwhile, the planting quality of the Guanyang red dates can be improved; the soil structure can be improved; the looseness and the porosity of the soil layer can be retained by formation of a soil aggregate structure; the soil fertility is improved; the adsorption of the fertilizer of the Guanyang red date root systems is accelerated; the effects of reducing consumption and improving fertility can be achieved; the fertilizer has the prospect of providing good economic benefits to the Guanyang red date planting farmers.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a special compound fertilizer for Guanyang jujube and a preparation method thereof. Background technique [0002] Guanyang red dates, Guanyang red dates are produced in Guanyang, Guangxi. It has the characteristics of large fruit, small core, thick flesh, and sweet and mellow taste. Candied dates made from it are sold well at home and abroad. Jujube also has high medicinal value. It is mainly used to treat confidant evil qi, nourish the temper, calm the stomach qi, unblock the nine orifices, help the twelve meridians, replenish less qi, less body fluid, and deficiency in the body.

Problems solved by technology

[0003] At present, there are many types of fertilizers used for planting Guanyang jujube, and most of the special fertilizers for Guanyang jujube are purchased from the market. However, most of the existing fertilizers for Guanyang jujube are chemical fertilizers. The growth of Yang jujube is needed, but the duration of fertilizer effect is short, and the absorption rate of Guanyang jujube is also low. Long-term use will destroy the soil aggregate structure, easily cause soil compaction, soil hardening, and severely damage the soil, thus It affects the growth of Guanyang jujube, and has no obvious effect on promoting the growth of Guanyang jujube. However, the application of chemical fertilizers is heavy on nitrogen and light on phosphorus and potassium, and neglects to supplement calcium, magnesium and other medium and trace elements, resulting in an imbalance of organic and inorganic ratios in fertilizer application, nitrogen and phosphorus. Potassium imbalance, lack of medium and trace elements and low availability affect the quality and fruit setting rate of Guanyang jujube

[0004] In the prior art, Chinese patent, application number: 201510490399.0: applicant: Qingdao Baotangxin Agricultural Machinery Co., Ltd.; invention name: a kind of jujube chemical fertilizer, including the following components according to the mass parts: nitrogen fertilizer 8-10 parts, phosphate fertilizer 4- 6 parts, boric acid 6-8 parts, hydrated lime 8-10 parts, pomegranate peel powder 30-50 parts, dried pig manure 80-90 parts, humic acid 7-9 parts, plant ash 40-60 parts, potassium dihydrogen phosphate 9- 11 parts, 80-100 parts of bentonite, 0.6-0.8 parts of borax, and 9-11 parts of distiller's grains. Although the fertilizer has simple ingredients and is easy to make, it overcomes the problem that traditional chemical fertilizers are likely to cause environmental pollution, but it cannot effectively protect the soil structure. , It is easy to cause soil salinization, which will cause damage to the roots of Guanyang jujube trees. Long-term use will cause damage accumulation, and it is difficult to achieve the expected effect, and it is difficult to bring economic benefits to Guanyang jujube growers.
