Problems solved by technology

Various rice seedling strengthening agents sold in the existing market are mainly composed of a single pesticide Dihuang powder and the constant elements N, P, and K. It is a mixture of medicine and fertilizer. Its antibacterial effect is poor and has limitations, and its fertility and acidity are insufficient.
The main manifestations are: the acidity of the seedbed soil is not enough to meet the physiological acidity needs of the rice seedlings, the seedlings bred have no obvious effect on resistance to damp-off and bacterial wilt, the seedlings are seriously defatted, the root system is not strong, and the overall quality of the seedlings is low. It takes a long time to slow down the seedlings after transplanting, and the high-yield performance is poor
On the whole, the quality and high-yield performance of the seedlings bred by the products used cannot meet the requirements of the dry seedling and sparse planting cultivation technology of rice.

Abstract

The composition of DSK rice shoots strenthening agent with clear disease-resisting effect, durable acid-regualting time and obvious fertilizer-raising action contains medicine; organic substance and fertilizer according to the mixing ratio of 1:7:7 as effective components, in which the medicine is formed from 20% of compounded preparation prepared with 3.3% thiram and metalaxyl and 80% of potter's earth additive; the organic substance is formed from discards of plant straw and slalks, its pH value is 5.0-6.0; and the fertilizer is formed from 70% of macroelements, 20% of secondary elements and 10% of trace elements. It can raise adverse resistance of rice, and possesses obvious effect for preventing and curing seedling blight and rhizoctonia disease of rice.

Description

technical field [0001] The invention relates to the technical field of rice seedling strengthening agent. Background technique [0002] Heilongjiang Province is a large agricultural province and one of the country's important commodity grain bases. The main cultivated crops are corn, soybean, rice, wheat and other grain crops. Among them, the cultivated area of ​​rice is more than 26 million mu. The rice mainly adopts the dry seedling and sparse planting cultivation technology, and the rice seedling strengthening agent used in the dry seedling has application Insufficient effect. Various rice seedling strengthening agents sold in the existing market are mainly composed of a single pesticide Dihuang powder and the constant elements N, P, and K. It is a mixture of medicine and fertilizer. Its antibacterial effect is poor and has limitations, and its fertility and acidity are insufficient. . The main manifestations are: the acidity of the seedbed soil is not enough to meet t...
