Special sunshine rose grape organic fertilizer and preparation method thereof

Abstract

The invention discloses a special sunshine rose grape organic fertilizer and a preparation method thereof. The organic fertilizer comprises modified starch which is prepared from starch which is subjected to magnetization modification with chitosan and sodium salt. The preparation method of the organic fertilizer comprises the following steps: fermenting plant ash, livestock excrement and grape wine distillers' grains with EM (Effective Microorganism) bacteria, and drying so as to obtain a composted fertilizer; dissolving a nitrogen phosphorus and potassium fertilizer, a growth regulator, bamboo vinegar and trace elements with water, adding the composted fertilizer, kieselguhr, attapulgite, nicotinamide and crotonic anhydride, and pelletizing so as to obtain fertilizer granules; dissolvingstarch with water, heating to implement gelatinization, adding chitosan, sodium metasilicate and sodium pyrophosphate, and carrying out magnetization modification so as to obtain modified starch; spraying the modified starch on the fertilizer granules, and drying, thereby obtaining the special organic fertilizer. The special organic fertilizer disclosed by the invention is comprehensive in nutrition, reasonable in proportioning, good in slow release property, good in permeability, high in stability and large in granule density, and the preparation method is simple in process, good in operability, easy in raw material, low in cost, rapid in granule molding and high in finished product rate.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a special organic fertilizer for sunshine rose grapes and a preparation method thereof. technical background [0002] Sunshine Rose grape, alias: Xiayin Muscat, Dazzling Rose, is a diploid European and American hybrid, bred by the Japanese Fruit Tree Experimental Field, and its parents are "Anyunjin 21" and "Bainan". The skin of this variety is golden yellow, the fruit is large, the fruit has a high sugar content, the flesh is hard and brittle, has a rose fragrance, and the soluble solid content is about 20%. Storage and transportation, no threshing phenomenon, extremely night color, easy high yield, strong disease resistance and other advantages, it is currently the main grape variety in domestic grape production, and is also deeply loved by consumers and growers. [0003] In recent years, with the substantial adjustment of the planting structure, the planting are...

Problems solved by technology

At present, fertilizers are classified according to their main components, including macroelement fertilizers, medium and trace element fertilizers, amino acid fertilizers, humic acid fertilizers, microbial fertilizers, organic fertilizers, seaweed fertilizers, earthworm fertilizers, biological enzyme fertilizers, polysaccharide fertilizers, etc. However, most of the existing fertilizers on the market are simply mixed with a single or several main components, and the nutrition is single and incomplete; there is no scientific proportioning according to soil fertility and crop demand; the nutritional proportioning is unscientific, and different degrees of Causes excess or lack of nutrients, resulting in imbalance of microbial flora, low bioavailability, disordered soil structure (acidification, compaction, salinization, reduction of flora, excessive levels of some elements, etc.), resulting in unbalanced soil environment; organic fertilizer Decomposition is not complete, diseases, insects and weeds are not killed by high temperature, and they are applied to the ground to continue fermentation and burn seedlings; a large amount of pesticides are abused, the resistance of diseases and insect pests is enhanced, and the pesticide residues of agricultural products also increase at the same time, which not only leads to imbalanced plant nutrition, but also leads to crop growth. Unhealthy and low-quality agricultural products, the serious consequences of low income for growers, and pollution to the environment and irreversible damage to nature
