Description
Technical Field
The invention relates to the technical field of tobacco planting, in particular to a compound oligosaccharide microelement fertilizer for tobacco planting and a preparation method thereof.
Background
China is a big agricultural country, and agriculture is the foundation of national economy and is the first industry which cannot be replaced. Modern agriculture is characterized by low input, high output, high efficiency and sustainable development. The closely related fertilizer industry and water resource utilization are more important material bases for modern agricultural production and development. Chemical fertilizers play an important role in agricultural production. In the process of fertilizing fruits and vegetables, the nutrition of the fertilizer is beneficial to plants, but the unreasonable or unbalanced fertilizer matching is easy to damage crops.
In modern agricultural production, the effect of increasing the yield by increasing the amount of fertilizer is limited, and the use of a large amount of fertilizer in soil can destroy the fertility of the soil, so that how to improve the utilization rate of the fertilizer and the resistance of crops becomes a difficult problem.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the compound oligosaccharide microelement fertilizer for tobacco planting and the preparation method thereof, which can promote the micro-ecological balance of soil, improve the stress resistance of tobacco, improve the quality and increase the yield.
The invention is realized by the following technical scheme:
the compound oligosaccharide microelement fertilizer for tobacco planting comprises the following components in percentage by mass:

Further, 2.2 to 2.8 percent of active yeast selenium, 35 to 45 percent of zinc sulfate, 21 to 24 percent of copper sulfate, 3.1 to 3.8 percent of chitosan oligosaccharide, 3.2 to 4.8 percent of seaweed polysaccharide, 40 to 42 percent of plant amino acid and 1 to 2 percent of phytic acid.
Further, the plant amino acids are at least two of glycine, methionine, leucine, lysine, alanine, histidine and aspartic acid.
A preparation method of a compound oligosaccharide trace element fertilizer for tobacco planting comprises the steps of weighing and mixing the components, adjusting the moisture content, adding a proper amount of vitamin B powder, uniformly stirring to obtain a mixture, and carrying out extrusion granulation, drying, cooling and sieving on the mixture to obtain the trace element fertilizer.
Vitamin B is added during granulation, so that rooting of tobacco and growth of leaves can be promoted when an element fertilizer is applied, and strong and green leaves of plants are enabled to be dark green, wherein: after being dissolved in water, the vitamin b2 can decompose salicylic acid, is favorable for the preference of weakly acidic soil of tobacco, can improve the disease resistance of plants, promote the growth of plant roots, improve the brightness of plant leaves and inhibit the growth of mosquitoes.
Further, the obtained trace element fertilizer particles are put into a coating machine, a nitrification inhibitor is uniformly scattered on the surfaces of the trace element fertilizer particles, and the trace element fertilizer particles are adhered to the surfaces of the trace element fertilizer particles by using mist coating liquid to complete coating treatment.
Further, the coating liquid is prepared by uniformly mixing 8% of phosphite ester, 25% of polyvinyl alcohol, 12% of starch, 3% of caramel pigment and 52% of water.
The phosphate contains alkyl trivalent phosphorus, so that the antioxidant effect is outstanding, the peroxide generated in the oxidation process is decomposed to generate a stable inactive product, and the formation of a free radical chain is stopped, so that the oxidation process is delayed, and the phosphate is coated outside the trace element fertilizer particles under the excellent film forming effect of the polyvinyl alcohol, so that the requirement of the prepared bacterial fertilizer on the environment is greatly reduced when the bacterial fertilizer is placed for a long time, and the bacterial fertilizer is not easy to deteriorate, so that the normal use effect can be achieved.
Further, the nitrification inhibitor is one of nitropyridine or thiosulfate. The addition of the nitrification inhibitor can inhibit the biotransformation process of converting ammonium nitrogen into nitrate nitrogen, and reduce the loss of nitrogen fertilizer in the form of nitrate nitrogen and the influence on the ecological environment by reducing the generation and accumulation of the nitrate nitrogen in soil.
The invention has the beneficial effects that:
the trace element fertilizer disclosed by the invention can effectively improve the utilization rate of the fertilizer by adding polyglutamic acid, so that the yield of crops is improved, and the leaves of the crops are thick, the color is dark, the photosynthesis is enhanced, the root systems of the crops are developed, the lodging resistance of the crops is improved, the lodging resistance, the drought resistance, the salt resistance and the disease resistance are obviously improved, and the quality of the crop products is greatly improved.
