Multi-effect nutritional agent for seedling raising of paddy field

Abstract

The invention discloses a multi-effect nutritional agent for the seedling raising of a paddy field. The multi-effect nutritional agent comprises the following components in percentage by weight: 3.25 to 5.60 percent of ammonium chloride, 33.56 to 57.83 percent of urea, 18.18 to 34.09 percent of ammonium dihydrogen phosphate, 11.67 to 20.00 percent of potassium chloride, 2.00 to 3.00 percent of zinc sulfate, 2.00 to 6.00 percent of sodium silicate, 0.04 to 0.08 percent of 98 weight percent sodium nitrophenolate, 0.10 to 0.20 percent of 15 weight percent multi-effect triazole and 2.40 to 5.80 percent of filler, wherein the filler is bentonite or grassplot. The multi-effect nutritional agent can meet nutrition required by the growth of paddy, relieve the harm of reductive toxic substances and meet the seedling raising requirements of enhancing disease resistance, insect resistance and adversity resistance, regulating growth and promoting tillering in the paddy field, is favorable for culturing multi-tillering seedlings, and establishes the foundation for high yield of the paddy field.

Description

technical field [0001] The invention relates to an agricultural composition, in particular to fertilizers and pesticides in the agricultural composition, in particular to a multi-effect nutrient for paddy field seedling cultivation of rice. Background technique [0002] During the rice seedling raising period, the seedlings are affected by harsh natural conditions such as low temperature, cold current, and hypoxia, and are vulnerable to pests and diseases. At the same time, factors such as unreasonable fertilization, unbalanced nutrients, and poisonous substances have also greatly affected the growth and development of rice seedlings. Rice seedlings will have symptoms such as rotten buds, black roots, white leaves, yellow leaves, and sitting studs. The specific manifestations are slow leaf emergence, brown or reddish-brown spots on the leaves and leaf sheaths, stagnant tillers; clusters of rice clusters, and a small amount of roots. , thin, thin, and irregular color; eventu...

AI Technical Summary

Problems solved by technology

This method of symptomatic protection after the onset increases labor and production costs to a certain extent. At the same time, the growth and development of rice has been affected, resulting in a decline in rice yield and quality.

[0004] At present, there is no good preventive solution for rice seedling cultivation in the market
