Special anti-disease yield-increase selenium-rich leaf surface absorption nutrient solution for paddy and preparation method thereof

Abstract

The invention relates to a special anti-disease yield-increase selenium-rich leaf surface absorption nutrient solution for paddy. The nutrient solution comprises, by weight, the raw materials of 0.75%of organic selenium, 1.67% of humic acid, 6.67% of urea, 4.5% of monopotassium phosphate, 0.81% of potassium sulfate, 0.58% of calcium peroxide, 0.47% of silicon dioxide, 0.25% of magnesium sulfate,0.21% of ferrous sulfate, 0.47% of zinc sulfate, 0.54% of boron, 0.06% of ammonium molybdate, 0.45% of manntiol-ca, 0.47% of amino-oligosaccharin, 0.52% of methionine, 1.45% of magnesium aluminum silicate, 0.17% of clay, 0.15% of citric acid, 0.05% of xylitol, 0.35% of xanthan gum, 0.29% of houttuynia cordata, 0.25% of dandelion, 0.25% of portulaca oleracea, 0.22% of vervain, 0.43% of radix euphorbiae lantu and the balance water. The special anti-disease yield-increase selenium-rich leaf surface absorption nutrient solution for paddy contains rich humic acid, nitrogen, phosphor and potassium and rich medium trace elements and other active substances, resists to lodging, increases the maturing rate, and increases the yield, and the content of a selenium element in the paddy is obviously increased; YNA active factors are activated comprehensively, heavy metal, chemical fertilizer, pesticide residues and other harmful substances of all types are effectively degraded, and chemical damage and fertilizer damage caused by inappropriate usage are repaired.

Description

technical field [0001] The invention relates to the field of agricultural auxiliaries, in particular to a selenium-enriched leaf-absorbing nutrient solution special for rice disease prevention and production increase and a preparation method thereof. Background technique [0002] Fertilizers play an indispensable role in agricultural production. At the same time, a large amount of fertilizers also have a serious impact on the environment. The low utilization rate of fertilizers, the imbalance of fertilizer nutrient ratio and the difference in release frequency lead to waste and pollution of fertilizers. Not only does it have a direct impact on the soil of the planting site, but it also has a terrible impact on the water body when it is lost to the lake due to the flow of water. This also makes foliar fertilizer more and more people's attention. Liquid fertilizer can directly act on the leaves of crops. , stems and other parts are absorbed through the pores on the surface of ...

AI Technical Summary

Problems solved by technology

[0003] The use of foliar fertilizers can prevent the fixation of nutrients in the soil, and there is no loss or reduction of effectiveness and utilization due to soil denitrification, leaching, etc., but the way leaves absorb foliar fertilizers is similar to the root system, mainly through leaves The stomata on the surface absorb and enter the mesophyll cells, and then penetrate into the cuticle and cellulose wall of the leaf surface through free diffusion. The absorption speed is slightly slower than the drying speed of the liquid surface fertilizer on the leaf surface. Generally, the nutrient absorption of fruit trees When the speed reaches 50%, it is generally 1-12 hours, and sometimes it takes several days for vegetable crops. However, the outermost layer of the epidermal tissue of the leaves is waxy, which has a hydrophobic effect, which is not conducive to the attachment of foliar fertilizers. The effect of surface tension makes it difficult to pass through the fine stomata of leaves, so how to improve the adsorption effect of foliar fertilizer on the leaf surface and reduce the surface tension of foliar fertilizer is a key issue
