Performance testing
The performance of the selenium-rich fertilizer prepared in example 1-2 was tested and compared with the products of comparative example 1-2, specifically, the pure water of comparative example 1 was used as a control group, and the existing inorganic selenium fertilizer product in comparative example 2 was used as a reference to perform a comparative index test, and the results of the rice yield influence obtained by spraying the above products on rice leaf surfaces (the amount of each product was the same, and other operating conditions were the same) were shown in table 1. Wherein, in table 1, different lower case letters of the same group of data indicate a significance level of 5% (P <0.05), and upper case letters indicate a significance level of 1% (P < 0.01).
TABLE 1 influence of Rice yield results table
The data in the table 1 show that the selenium-rich fertilizer prepared by the invention is used for planting selenium-rich rice, and the fertilizer product contains rich active organic nutrition and trace element nutrition, so that the requirements of the rice on trace elements and organic nutrition can be met, the growth of the rice is greatly promoted, the rice yield of the rice is remarkably increased by 7-35%, the selenium content of the rice is 0.2-0.4mg/kg, and more than 85% of total selenium in the rice is selenomethionine selenium; the selenium content of the rice produced by applying the fertilizer meets the local standard of selenium content of Guangxi selenium-rich rice (the selenium content classification requirement of DB 45/T1061-2014 selenium-rich agricultural products) selenium content requirement (see figures 1 and 2, wherein figure 1 is a result graph of the total selenium content of the rice produced by spraying different products on leaf surfaces, and figure 2 is a result graph of the proportion of selenomethionine selenium in the rice produced by spraying different products on leaf surfaces to the total selenium). Moreover, the selenium-rich fertilizer prepared by the invention contains a plant immune activator, and after being absorbed by rice leaves, the selenium-rich fertilizer activates the rice body to generate disease-resistant protein, so that the disease damage is reduced; the selenium-rich fertilizer prepared by the invention is combined into a whole, can reduce the operation of farm works, saves time, labor and labor, and has wide market prospect.
The selenium-rich fertilizer provided by the invention can be used for producing selenium-rich rice by compounding various raw materials such as citric acid, potassium selenate, 5-aminolevulinic acid, polypeptide, potassium fulvate, brassinolide, chitosan oligosaccharide, boric acid, zinc sulfate, ferrous sulfate heptahydrate, copper sulfate pentahydrate, potassium metasilicate, polyhydric alcohol, probenazole, dimethyl sulfoxide, diethylaminoethanol butyrate, trimethyl ammonium bromide, alkyl glycoside and the like, and solves the problems that the existing selenium-rich fertilizer is mostly selenium-containing inorganic salt and is difficult to produce rice with high selenium-rich organic selenium content, and the produced rice contains 0.2-0.4mg/kg selenium, more than 85% of total selenium is selenomethionine selenium.
It needs to be further explained that the existing inorganic selenium fertilizer has the following defects in the production of selenium-enriched rice: the produced selenium-rich rice has the risk of overhigh content of inorganic selenium; the instability of the efficiency of absorbing and utilizing the inorganic selenium fertilizer by the rice leads to the uncertainty of the selenium content of the rice and brings the stability risk of the production of the selenium-rich rice; the existing inorganic selenium fertilizer does not have the effects of improving the disease resistance of rice and increasing yield and quality, and the selenium-rich fertilizer provided by the invention can solve the problems. The selenium-rich fertilizer which can be used for planting selenium-rich rice at present is mainly a fertilizer containing inorganic selenium, and is essentially different from the selenium-rich fertilizer (containing diethylaminoethanol butyrate polypeptide chelated selenium fertilizer) provided by the invention, and the selenium-rich fertilizer can provide a fertilizer which can activate rice disease-resistant genes, increase the photosynthesis efficiency of rice leaves and supply polypeptide chelated selenium nutrition for planting selenium for the selenium-rich rice, so that the organic selenium content of rice grains and the grain yield are improved; the selenium-rich fertilizer of the invention can lead the selenium content of rice grains to reach the related national and local selenium-rich rice standards, and realize the yield and efficiency increase of rice production.
While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
