Organic water-retaining suspension liquid compound fertilizer and preparation method thereof

Abstract

The invention provides an organic water-retaining suspension liquid compound fertilizer and a preparation method thereof. The organic water-retaining suspension liquid compound fertilizer is preparedby effectively compounding organic matters and microorganisms. When being applied to stony desertification areas, the fertilizer can effectively promote the development of soil microorganisms, improvethe activity of the soil microorganisms and improve the microbial environment, and can effectively retain water and fertilizer, improve the soil root system environment of crops planted in stony desertification areas and improve the turnover utilization efficiency of soil organic matters, thereby improving the survival rate, yield and quality of the crops. The suspension liquid compound fertilizer disclosed by the invention is complete in nutrients, reasonable in proportion, good in flowability and suitable for automatic fertilization operation with a relatively large area, and can obviouslyimprove the fertilization efficiency and increase the yield and income of crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production. More specifically, it relates to an organic water-retaining suspension liquid compound fertilizer and a preparation method thereof. Background technique [0002] Rocky desertification (Rocky desertification) refers to the natural background of karst landform development in tropical and subtropical humid and semi-humid areas, which is disturbed by human activities, causing serious damage to vegetation and serious soil erosion. The land degradation process in which the bedrock is largely exposed or gravel is accumulated is an extreme form of land degradation. Vegetation is scarce on rocky desertification land, and soil erosion is serious, resulting in low production efficiency of land with barren soil. Serious rocky desertification will not only bring about ecological problems such as increased soil erosion, reduced vegetation coverage, deterioration of the ecological environment, f...

Problems solved by technology

For example, patent 201611242423.X provides a microbial fertilizer for improving and increasing fertilizer in rocky desertification soil and its manufacturing method. It is composed of basic fertilizer, improved fertilizer, and nutrient powder with preserved microorganisms, but the proportion of microorganisms is low The number of effective viable bacteria is low, and the added microbial population is large, the colonization ability is poor in the soil of sandy rocky desertification area, it is difficult to form a dominant population, and its life span is short, so the treatment time is short

Patent 201910692069.8 discloses a microbial water-retaining water-soluble fertilizer for reclamation of rocky desertification bauxite mining areas and its preparation method, but the method is complicated to prepare and the cost is high, and the fertilizer is applied to the soil, giving vegetation less nutrients, nitrogen, Phosphorus, potassium content and microbial content are very low

At present, on the whole, due to the high rate of exposed rocks in rocky desertification areas, less soil, less soil microbial dominant flora, and low water storage capacity, the content of effective microorganisms in such microbial fertilizers for rocky desertification soil improvement is relatively low. , the effect of increasing the abundance of soil microbial communities and increasing the content of soil organic matter is poor, and the purpose of effectively improving soil physical and chemical properties cannot be achieved.

And for the rocky desertification area, the soil is mainly composed of sand, silt, and stones, the soil layer is particularly barren, the ecosystem is relatively fragile, the fertilizer and water retention is poor, and the drought resistance is weak; the content of soil organic matter, nitrogen, phosphorus, and potassium is low, and the soil Poor fertility, very unfavorable to plant growth
