Selenium-enriched foliar fertilizer for paddy rice

Abstract

The invention discloses a selenium-enriched foliar fertilizer for paddy rice. The selenium-enriched foliar fertilizer for the paddy rice is prepared from the following raw materials in parts by weight: 6-8 parts of hypsizygus marmoreus, 10-12 parts of pleurotus geesteranus, 1.1 -1.3 parts of radix astragali, 1.2-1.4 parts of rhizoma cyperi, 0.6-0.8 parts of aster, 0.7-0.9 parts of california burclover herb, 1.3-1.5 parts of Speranskia cantonensis, 3-5 parts of garlic, 1-2 parts of beer yeast, 4-6 parts of wheat germs, 7-9 parts of clam meat, 14-16 parts of pork liver, 0.42-0.44 parts of compound sugar alcohol and 0.31-0.33 parts of compound enzyme. The raw materials of the selenium-enriched foliar fertilizer for the paddy rice contain multiple traditional Chinese medicinal ingredients with rich selenium elements, are scientific in compatibility, and supplement each other in function; not only can selenium element absorption and utilization of the paddy rice be facilitated, but also the pest rate of rice plant hoppers and the disease rate of rice blasts of the paddy rice can be effectively decreased, so that the yield of the paddy rice is improved; the clam meat and the pork liver with rich selenium elements are added into the raw materials; the adhesive force, on leaf surfaces of the paddy rice, of the foliar fertilizer can be effectively improved; an occurrence of a status that a foliar fertilizer falls off from the leaf surfaces after being applied in a spraying manner is effectively avoided, so that an action effect, on the paddy rice, of the foliar fertilizer is enhanced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a selenium-enriched rice leaf fertilizer. Background technique [0002] Foliar fertilizer is a fertilizer that directly applies the nutrients required by the crop to the leaf surface for the purpose of leaf absorption. Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its function through the absorption of leaves. The leaves of plants have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and waxes on the outside of the cells on the surface. It can protect the mesophyll cells under the epidermis to perform photosynthesis, respiration and other functions, and not be affected by changes in external adverse conditions. There are many tiny pores on the surface of the leaves, which perform the function of gas replacement. In the process of rice growth, rice has already shown some ...

AI Technical Summary

Problems solved by technology

At present, the common selenium-enriched fertilizers in the market are mainly the mixture of selenium ore powder and traditional chemical fertilizers. Since natural selenium exists in the state of inorganic compounds, it is not easy for plants to absorb and transform, so it is easy to cause waste of resources and environmental pollution.
