Oat efficient culture slow-release fertilizer in salt stress soil and preparation method of oat efficient culture slow-release fertilizer

Abstract

The invention discloses an oat efficient culture slow-release fertilizer in salt stress soil. The oat efficient culture slow-release fertilizer is prepared from the following ingredients in parts by weight: paraffin, calcium peroxide, camphorated oil, nanometer porous bamboo charcoal, humic acid water-soluble fertilizers, pyroclastic rock, animal bone meal, corncob powder, rice hull powder, lactose, expanded loofah sponge fiber, selenium-enriched yeast, amino acid complexing zinc iron and copper mineral elements, selenomethionine, sodium metasilicate, amino oligosaccharin, mannan oligosaccharides, sodium butyrate, ribonucleotide, croscarmellose sodium, gelatinized starch, activated attapulgite and the like. The oat efficient culture slow-release fertilizer in the salt stress soil is prepared by coating fermentation main materials with a film coating solution capable of dynamically releasing nutrients; the slow release effect is good; the nutrition is rich; the fertilizer action time is long; through assistance of the regulation and control on the slow release performance of the film coating material by the salt stress, the absorption and utilization rate of the fertilizer by oat root sheaths can be improved, so that cultured oat seeds are full; the single plant ear grain number is increased; the yield is high; the benefits are high.

Description

technical field [0001] The invention relates to the technical field of agricultural slow-release fertilizers, in particular to a slow-release fertilizer for high-efficiency cultivation of oats in salt-stressed soil and a preparation method thereof. Background technique [0002] Fertilizer is the food of plants, and it is the largest material investment in the production of plants, especially crops. The long-term use of fertilizers and fertilizers, combined with the comprehensive impact of the soil environment, makes the utilization rate of fertilizers become lower and lower. This is also the use of fertilizers and fertilizers. In addition, unreasonable fertilization has also caused a series of problems such as environmental pollution and threats to the quality and safety of plant and crop products. In the face of these increasingly prominent and more serious problems, it is necessary to improve fertilizer and chemical fertilizers. Taking the road of sustainable development h...

Problems solved by technology

[0004] The currently developed coating materials use static membrane pores to release nutrients. Usually, the film thickness is adjusted or materials with different properties are used to control the release rate. There are few reports on the control of nutrient release through dynamic membrane pores.
