Seedling strengthening agent for rice seedling culture and use method thereof

Abstract

The invention provides a seedling strengthening agent for rice seedling culture and a use method thereof. The seedling strengthening agent is prepared from the following raw materials in percentage by weight: 45 to 55% of nutrient agent, 8 to 12% of acid regulator, 0.5 to 1.2% of sterilizing and disinfecting agent, and the balance of turfy soil, wherein the nutrient agent is prepared by mixing ammonium sulfate, urea, monopotassium phosphate, potassium humate, calcium magnesium phosphate fertilizer, silicon fertilizer, zinc sulfate, and ammonium ferrous sulfate according to a mass ratio of 1:(0.1 to 0.3):(0.05 to 0.1):(0.2 to 0.4):(0.2 to 0.3):(0.1 to 0.2):(0.02 to 0.06):(0.01 to 0.03); the acid regulator is prepared by mixing concentrated sulfuric acid and natural material with high acid maintaining property; the sterilizing and disinfecting agent is prepared by mixing 10% fubol wettable powder and potassium permanganate according to a mass ratio of 1:(0.2 to 0.7); the natural material with high acid maintaining property is selected from one of straw biomass carbon, expanded vermiculite, and diatomite tailings. The use method comprises the following steps of mixing seedling bed soil and the seedling strengthening agent, primarily adjusting, and slightly adjusting according to the pH (potential of hydrogen) value of the primarily adjusted bed soil. The seedling strengthening agent for rice seedling culture has the advantages that the excellent seedling strengthening, root promoting, greening and disease-resisting functions are realized, the acid stability is higher, and the easiness in recovery of the pH value is avoided.

Description

technical field

[0001] The invention relates to the field of rice seedling raising, in particular to a rice seedling raising and seedling strengthening agent and a use method thereof. Background technique

[0002] Realizing the mechanization of rice production is an inevitable trend in the development of modern rice farming. Mechanization of rice farming is to replace traditional handicraft operations with modern industrial means. It can not only reduce the labor intensity of rice farming, but also facilitate the development of large-scale rice farming, promote the transfer of labor force, improve labor productivity and overall productivity, stabilize grain production, and effectively It is conducive to promoting the popularization and application of modern scientific and technological achievements, and accelerating the pace of realizing modern agriculture. The machine-transplanted rice seedling raising method is different from the conventional seedling raising method. Its ...
