Problems solved by technology

For a long time, rice has generally used ammonium sulfate and urea when turning green and tillering. When these two fertilizers encounter water and high temperature, the fertilizer effect cannot be fully exerted due to water evaporation. If they are used too much, it is easy to burn the seedlings and get erythema.

Embodiment Construction

[0009] The special fertilizer for long-acting rice of the present invention, preparation steps:

[0010] 1. First, crush the rice husk ash to 40-60 mesh, and then carry out the acid adjustment treatment, so that the pH value reaches 5-6. Add the crushed potassium humate at 10-20% of the weight ratio of the rice husk ash, and stir for 2 hour, then reacted in the reactor for 6 hours;

[0011] 2. Crush the humic acid accounting for 5-20% of the weight of superphosphate to 40-60 meshes, add accelerator ammonia water with a concentration of 3-10% accounting for 1-10% of the weight of superphosphate, and add 1 - 10% comprehensive agent zinc sulfate, mixed with superphosphate, stirred for 2 hours, then reacted in the reactor for 1-2 hours, and controlled the temperature at 30-100°C to obtain citrate-soluble phosphorus;

[0012] 3. Ferment with horse, cow, pig and chicken manure, control the temperature between 55-65°C during fermentation, and ferment for 5-7 days, and form an active...

Abstract

The long-acting rice fertilizer is fertilizer specially for rice and has rice hull ash with trace elements as main material compounded with citric soluble phosphate fertilizer, urea, potash fertilizer, etc. Field experiment shows that the trace elements in the long-acting rice fertilizer are absorbed easily by rice with mutually synergistic effect. Burnt rice hull ash contains trace elements and organic elements essential for crop, and has the functions of killing bacteria, loosen soil, raise the water absorbing capacity and temperature of soil, promote rice seedling growth and raise rice yield.

Description

technical field [0001] The invention relates to a special fertilizer for rice, which can be used as base fertilizer for rice and top dressing in the field. Background technique [0002] Rice absorbs different nutrients in different growth stages. Therefore, it is necessary to apply fertilizers in stages according to the nutrient needs of rice in each growth stage. Base fertilizer is the basic fertilizer source for the whole process of rice development and growth. In the process of growth, such as greening, tillering, and ear raising, it is especially necessary to promote plant growth and fertilizer efficiency enhancers mainly composed of trace elements and supplemented by humus and zinc sulfate. For a long time, rice has generally used ammonium sulfate and urea when turning green and tillering. When these two fertilizers encounter water and high temperature, the fertilizer effect cannot be fully exerted due to water evaporation. Contents of the invention [0003] The obje...
