Fruit-protecting bio-organic fertilizer and preparation method

Abstract

The invention relates to the technical field of agricultural bio-organic fertilizer, in particular to fruit-protecting bio-organic fertilizer and a preparation method. The organic fertilizer is prepared from organic water fertilizer and a solid organic fertilizer carrier through mixing and wet composting, wherein the organic water fertilizer is prepared from two or more of industrial waste, including cassava residues, sugarcane chaff, straw and molasses concentrated solutions, produced during sugar manufacture and alcohol production and two or more auxiliary materials including potassium ash, furnace ash, kaolin, spirulina powder and plant ash through mixing, wet composting and fermentation; the solid organic fertilizer carrier comprises fishbone meal, silkworm cast and traditional Chinese medicine residues. Phosphorite waste is also added for fermentation, phosphorus enrichment is realized, harmful substances are removed through fermentation and filtration, and the environment-friendly, green and safe fruit-protecting bio-organic fertilizer is produced through mixing and fermentation of filtrate and the solid organic fertilizer carrier.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of agricultural bio-organic fertilizers, in particular to a fruit-preserving bio-organic fertilizer and a preparation method thereof. [0003] 【Background technique】 [0004] Phosphorus is one of the indispensable nutrients for plant growth and development, and most of the soil in my country is deficient in phosphorus. In agricultural production, a large amount of phosphate fertilizer needs to be applied every year, which consumes a lot of phosphate rock resources and energy. Such a huge demand for phosphate fertilizer and a large amount of phosphate rock mining have made the contradiction between the gradually depleted phosphate rock resources increasingly serious. Therefore, it is of great significance to fully tap the value of each link in the phosphate fertilizer industry chain, especially the reuse of waste tailings resources in the process of phosphate mining, to reduce the environmental pollut...

Problems solved by technology

[0005] However, excessive phosphorus fertilizer will make the respiration of crops too strong, the production of dry matter is less than the consumption, the imbalance of vegetative growth and reproductive growth, the reproductive growth will be accelerated, the crops will be short and premature, the number of ineffective tillers will increase, the grains will increase, and the yield will decrease; at the same time , Phosphorus fertilizer and zinc have a resistance effect. After zinc deficiency in crops, auxin will decrease, and excess phosphorus will combine with zinc to form zinc salt precipitation or zinc hydroxide precipitation, and the solubility of these two combinations is very low, thereby reducing the zinc content. Effectiveness, so that crops "get phosphorus and zinc deficiency", poor growth, difficult to high yield; moreover, excessive phosphorus will cause silicon deficiency in rice

Rice likes silicon, and when silicon is deficient, the leaves become brittle, the stems are slender, easy to lodging, and the disease resistance is reduced. Excessive phosphorus can reduce the effectiveness of silicon, because silicon can replace the phosphorus adsorbed under the soil particles. Increases the availability of phosphorus in the soil, but silicon is adsorbed and fixed by soil colloids, reducing the availability, resulting in silicon deficiency in rice; excessive phosphorus can also lead to molybdenum deficiency in crops. In normal crop nutrition, phosphorus and molybdenum have mutual Promoting effect, phosphorus can promote the absorption of molybdenum by crops, and the two are applied scientifically; it has a good effect of increasing production, but excessive phosphorus fertilizer can aggravate the lack of molybdenum, which will lead to molybdenum deficiency in crops
