Description
Technical Field
The invention relates to the technical field of fertilizers, and particularly relates to a special fertilizer for rice and a preparation method thereof.
Background
The rice is the first large grain crop in China in the second world, the area of the rice in China accounts for about 23% of the total area of the world, the rice is second to the second world in India, the rice has a strategic position in the food production in China, and the rice is taken as the staple food by two thirds of the population in China. At present, with the continuous cropping and the aggravation of multiple cropping indexes of rice, soil pathogenic bacteria are propagated in large quantity, so that rice soil-borne diseases are increasingly serious; and the fertilizing mode of the rice mainly depends on fertilizers with major elements such as nitrogen, phosphorus and potassium, and the supplement of medium and trace elements is neglected, so that the medium and trace elements in the rice soil are lacked, and the yield and the quality of the rice are seriously damaged.
The reed (Phragmitis australis), the genus Phragmites of Gramineae, perennial gramineae, is a kind of excellent pasture with wide adaptability, strong stress resistance and high biomass, the root, stem, flower and leaf of the reed contain rich biological active components, and modern pharmacology proves that the reed contains rich pentosan, coixol, protein, fat, carbohydrate, D-glucose, D-galactose, two kinds of uronic acid and more than ten kinds of vitamins B1, B2, C, etc. The reed has strong stress resistance and survival competitive ability, is grown in a humid and watery environment, is rarely attacked by plant diseases and insect pests under natural conditions, and can control pathogenic bacteria and pests attacking the reed and inhibit competition of other plants for living space and the like. Therefore, the reed extract and the degradation product have complete nutrient elements and resistant substances.
The reeds are widely distributed all over the country, and in areas with rich water resources, the reeds grow vigorously, and most of the reeds are directly burnt off except for being used as weaving and paper making materials, so that resources are wasted and the environment is polluted. The development of novel environment-friendly fertilizer by utilizing abundant reed resources undoubtedly has wide prospect. Meanwhile, the direct development and utilization of the degradation and fermentation products of the reeds have very important significance for the comprehensive development and utilization of the reed resources.
The rice is a silicon-loving crop, and the silicon can promote the growth of the rice, improve the resistance of the rice under stress conditions, improve the quality of the rice and increase the yield of the rice. At present, the varieties of silicon fertilizers mainly comprise two main types of citrate soluble silicon fertilizers and water soluble silicon fertilizers, wherein the citrate soluble silicon fertilizer is a silicon fertilizer which is insoluble in water and soluble in acid and can be absorbed by plants, the common citrate soluble silicon fertilizer is mainly prepared by processing waste steel slag, fly ash and ore of a steel mill through a high-temperature calcination process, the common citrate soluble silicon fertilizer is a silicon fertilizer which is soluble in water and can be directly absorbed by the plants, the absorption and utilization rate of the crops is high, the citrate soluble silicon fertilizer is high-temperature chemical synthesis, is generally commonly used for foliage spraying, flushing and drip irrigation, and is difficult to effectively use in rice crops. Therefore, the key problem to be solved is how to improve the production process, improve the utilization rate of the silicon fertilizer, organically combine the water-soluble silicon fertilizer and the base fertilizer, reduce the production cost and the fertilization times and reduce the labor cost.

Example 5: application of special fertilizer for rice
In the year 2020, from 4 months to 10 months, the rice fertilizer prepared in example 1 was compared with a rice fertilizer sold in the market, oryza sativa (manufactured by stedori (hunan) agricultural science and technology limited) and the fertilizer for comparison produced in example 4, i.e., a rice variety of SANFENG 47, by applying a soil testing formula, and a planting test was performed on rice crops. The disease resistance, growth, lodging resistance and yield of the three were compared (see table 1, table 2, table 3 and figures 1 to 6 in the drawings for details):
TABLE 1 fertilization conditions
TABLE 2 disease resistance and lodging
| Treatment of | Disease condition | Disease coverage | Lodging condition | Lodging rate |
| Rice fertilizer | Blast of rice | 37.22％ | Severe severity of disease | 35.37％ |
| Comparison fertilizer | Blast of rice | 10.76％ | In general | 13.84％ |
| The invention | Blast of rice | 9.32％ | Is lighter | 5.32％ |
TABLE 3 growth and yield
As can be seen by combining the table 2, the figure 1, the figure 2 and the figure 3, the coverage rate of the rice blast disease treated on the market is 37.22 percent, the coverage rate of the rice blast disease treated by the contrast fertilizer is 10.76 percent, the coverage rate of the rice blast disease treated by the special fertilizer for rice of the invention is 9.32 percent, and the areas of the rice blast disease treated by the special fertilizer for rice of the invention and the rice treated by the contrast fertilizer for rice are obviously lower than those of the products treated on the market, which shows that the active ingredients of the reed fermentation products effectively inhibit the breeding and reproduction of pathogenic bacteria and greatly reduce the disease incidence rate of the rice.
It can be seen from the combination of table 3, fig. 4, fig. 5 and fig. 6 that the plant height of the rice treated by the invention is obviously lower than that of the rice treated by the commercial product and is lower than that of the rice treated by the contrast fertilizer, the plant height is a determining factor of lodging resistance, and the rice is more prone to lodging due to too high plant height, and the plant height is greatly reduced and is lower than that of the rice treated by the contrast fertilizer, which shows that the silicon has obvious effect on the lodging resistance of the rice, and the expanded sodium silicate is better than that of the common water-soluble silicon fertilizer under the condition of the same dosage.
As can be seen by combining the table 2, the figure 1, the figure 2 and the figure 3, the tillering number and the thousand-kernel weight yield of the rice treated by the invention are obviously higher than those of the commercial products, and the yield of the rice treated by the invention is 732 kg/mu, which is 15.46% higher than that of the rice applied by the conventional water-soluble silicon fertilizer and 5.32% higher than that of the common water-soluble silicon fertilizer. After the puffed sodium silicate used as the silicon fertilizer is puffed, the puffed sodium silicate has obvious influence on the growth of rice, not only dwarfs the plant height and improves the lodging resistance of the rice, but also promotes the tillering of the rice, improves the maturing rate of rice grains and greatly improves the yield.
From this it can be concluded that: the special fertilizer for rice has obvious effects on preventing rice diseases, resisting lodging, stress and increasing yield.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
