Special spraying agent for rice

Abstract

The invention belongs to the technical field of fertilization of agricultural crops and particularly relates to a special spraying agent for rice. The special spraying agent contains a component A anda component B and is prepared by the steps of mixing the component A with the component B in a weight ratio of 1 to 1, adding 200-300 times of total weight of water, and uniformly mixing, so as to form the special spraying agent; the component A is mainly prepared by fermenting the raw materials of sticky rice, coffee grounds, tea cakes, rice bran and the like; and the component A contains rich organic nitrogen phosphorus and potassium and a large quantity of micromolecule amino acids, polysaccharide, vitamin, mineral nutrients, beneficial bacteria and the like. By compounding the component Awith substances such as bone meal, liquorice, medium trace elements and the like in the component B, the special spraying agent contains comprehensive and balanced nutrients, is rich in various nutrients and medium trace elements and is capable of rapidly supplementing nutrients required by rice, the utilization rate of the fertilizer is relatively high, the fertilizer efficiency is good and durable, and the growth of the rice is promoted, so that the yield of the rice is increased, and the quality of the rice is improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special spraying agent for rice, and belongs to the technical field of fertilization of agricultural crops. Background technique [0002] Rice, Latin scientific name: Oryza sativa, Oryza glaberrima, is an annual grass plant with long and flat leaves and panicles composed of many spikelets. It is an important food resource, and people in many parts of the world rely on it as a staple food. Especially in my country, rice is the main crop of our country's agriculture, which plays an important role in the adjustment of our country's agricultural structure and food security. The sown area of ​​rice in my country accounts for about 29 percent of all food crops, and about 60 percent of the population uses it as a staple food. However, at present, my country's population is growing rapidly and the area of ​​cultivated land continues to decrease. This also puts great pressure on the cultivation and suppl...

Problems solved by technology

However, in the current foliar fertilizer varieties, most of the foliar fertilizers have problems such as single fertilizer effect, narrow application range, difficult storage and transportation, poor stability, and high cost.

Moreover, the foliar spraying agent with a single fertilizer effect has an unsatisfactory effect on rice, which cannot meet the growth needs of rice, and the high production cost of fertilizer lacks economy.

At present, in order to provide comprehensive nutrition, many spraying agents like to add organic ingredients to supplement nutrients such as organic nitrogen for rice. The spraying agents added with organic matter generally have the problem of perishability and corruption, because many organic ingredients are perishable, resulting in The storage time of the spraying agent is short, and the fertilizer efficiency will be greatly reduced after deterioration, and even cause pathogenic bacteria, which will have a negative impact on the growth of rice.
