Embodiment Construction

[0013] The most preferred embodiment of the present invention: a kind of manufacture method of special fertilizer for rice weeding has the following processing steps:

[0014] a. Material preparation: mix and stir fresh chicken manure and straw bran in a ratio of 10:1 by weight, and the water content of fresh chicken manure is more than 70%;

[0015] b. Compost fermentation: Compost and ferment the above-mentioned mixed materials, raise the compost temperature to 50°C-60°C, keep the temperature for 10-15 days, the chicken manure will lose 20-25% of water, no odor, and it is regarded as fermentation complete;

[0016] c. Broken: Broken the above-mentioned fermented chicken manure, 100% crossed 80 mesh sieves;

[0017] d. Blending green bran: mix green bran with the above-mentioned broken chicken manure in a ratio of 1:1 by weight and stir evenly;

[0018] e. Extrusion granulation: Use an extrusion granulator to extrude and granulate the uniformly stirred mixture, and the gran...

Abstract

The present invention relates to fertilizer producing technology, and is especially herbicidal fertilizer for rice. The production process includes the following steps: 1. mixing fresh chicken manure with water content over 70 % and stalk powder in the weight ratio of 8-12 to 1; 2. stacking the mixture for fermentation until the chicken manure loses its water by 20-25 % and becomes odorless; 3. crushing; 4. mixing with crushed grass in the same weight; 5. extruding to palletize; and 6. cooling. The herbicidal fertilizer for rice is both fertilizer and herbicide with herbicidal rate over 90 %.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a method for producing a special fertilizer for rice weed control. Background technique [0002] Weeds in paddy fields are mainly propagated by grass seeds. With plowing and harrowing, the grass seeds in the soil are brought to the surface of the soil and begin to germinate under sufficient conditions of water, temperature and light. In the final greening period, the weeds grow rapidly. If weeds are not removed in time, the grass will grow faster than the rice, which will cause a serious reduction in production, or even extinction. At present, weeding in rice fields is mainly chemical weeding, supplemented by manual weeding. Not only is the operation cost high, but also the residues of chemical herbicides pollute the soil environment and water environment, especially the accumulation of residues in agricultural products directly threatens human health and life. Saf...
