Saline-alkali resistant and moisture resistant slow-release fertilizer for peanuts

Abstract

The present invention discloses saline-alkali resistant and moisture resistant slow-release fertilizer for peanuts. The fertilizer is characterized by comprising the follow components in parts by weight: 30-40 parts of urea, 16-18 parts of ammonium phosphate, 20-30 parts of soybean meal, 15-20 parts of potassium chloride, 12-14 parts of fly ash, 3-5 parts of polyaspartic acid, 3-5 parts of polysuccinimide, 2-4 parts of mancozeb, 3-5 parts of bactericide, 2-3 parts of brassinolide and 1-2 parts of trace element fertilizer. The fly ash of the fertilizer can make crop straws tough and lodging resistant. The soybean meal can absorb moisture of the wet granulated fertilizer and keep the granular state of the granulated fertilizer while being applied into the soil along with the granulated fertilizer, so that the organic fertilizer is applied into soil in addition. The component such as the bactericide can reduce the drug resistance of the crops and has excellent preventive and control effects. Moreover, the zinc content of peanuts is increased, and the peanut quality is improved.

Description

technical field [0001] The invention belongs to the field of fertilizer agriculture, and in particular relates to a salt-alkali-resistant and moisture-proof peanut slow-release fertilizer. Background technique [0002] In our country, the soils for cultivating peanuts are mostly hilly gravel soils, plain alluvial sandy soils, and southern red-yellow soils. These soil structures are poor, and organic fertilizers should be used to activate the soil, improve the structure, and fertilize the soil. Combined with the application of chemical fertilizers, timely supplement soil nutrients. Organic fertilizers contain a variety of nutrients, especially important sources of micronutrients, with long-lasting fertilizer effects. After the organic fertilizer is applied to the soil, it can continuously release various nutrients for peanuts to absorb and utilize through microbial decomposition, and can also continuously release carbon dioxide to improve the photosynthetic environment of pe...

Problems solved by technology

[0003] Mancozeb can provide zinc to plants. In addition to solving the symptoms of zinc deficiency in crops, it can also enhance the ability of plants to resist diseases, thereby relatively having a bactericidal effect, but it is unstable to light, heat, and humidity, and it is easy to decompose into carbon disulfide. , When encountering alkaline substances or copper, mercury and other substances, it is easy to decompose and release carbon disulfide to reduce its effect, and its volatility is small

At present, the traditional compound fertilizers on the market contain less nutrients, which cannot fully meet the needs of crop growth, and the price is high, and the effect of increasing production is not obvious. In addition, there are problems such as low fertilizer utilization rate and excessive application amount.

The currently used silicon-potassium fertilizer has short fertilizer efficiency, low utilization rate of active ingredients, single function, and cannot improve the utilization rate of binary compound fertilizer.

And it does not have antibacterial and saline-alkali resistance. Therefore, how to develop a kind of saline-alkali and moisture-proof peanut slow-release fertilizer has important practical significance
