Technical Field

The invention relates to a lobster breeding technology, in particular to a natural fertilizer for rice planting in a shrimp-raising rice field.

Background

The crayfish has delicious meat taste and rich nutrition, is deeply loved by people and is a main variety for shrimp culture at present. In recent years, as market demands are increased sharply, natural resources of crayfishes are reduced sharply, and prices are raised gradually, so that the market demands are met through artificial scientific breeding, more and more people begin to try ecological breeding, for example, crayfishes are bred in rice fields, the mixed breeding mode organically combines planting and breeding, and an ecological system created by manpower is fully utilized, so that crayfishes and rice are in mutual-profit symbiosis. The lobster breeding in the rice field has three advantages: firstly, increasing both production and income; secondly, the lobsters can eat weeds and aquatic organisms in the field without eating rice seedlings, can also kill harmful larvae including mosquitoes, and can play a role in weeding and removing pests; thirdly, the fish and the shrimp swim and forage for the rice, which is beneficial to loosening the soil, activating water and ventilating the rice field, can increase the dissolved oxygen of the water in the rice field, and simultaneously discharge a large amount of excrement through metabolism, thereby achieving the effect of increasing the fertilizer.

However, a significant technical difficulty exists in the current rice field shrimp culture process, namely how to enable the rice and the crayfish to achieve an optimal ecological balance effect and enable the rice to achieve the original yield on the basis of not influencing the growth of the shrimps.

Disclosure of Invention

The invention aims to solve the technical problems and provides a natural fertilizer for rice planting in shrimp-growing rice fields, which is a natural fertilizer, has no pollution and side effect, and does not influence the growth of shrimps while ensuring the growth of rice.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a natural fertilizer for rice planting in shrimp-raising rice fields is prepared from the following raw materials in parts by weight: 80-100 parts of bean dregs, 5-10 parts of kelp waste residues, 5-10 parts of oil cakes, 10-20 parts of animal dry manure, 10-20 parts of human urine, 150-200 parts of straws, 2-5 parts of tea stems, 50-60 parts of rice hull powder and 5-8 parts of fermentation strains.

Specifically, the feed is prepared from the following raw materials in parts by weight: 90 parts of bean dregs, 8 parts of kelp waste residues, 8 parts of oil cakes, 15 parts of animal dry manure, 15 parts of human urine, 150 parts of straws, 4 parts of tea stems, 60 parts of rice hull powder and 8 parts of fermentation strains.

Further, the composition also comprises 5-9 parts of indolebutyric acid, 2-5 parts of immunopotentiator and 3-4 parts of choline chloride.

Preferably, the composition comprises 7 parts of indolebutyric acid, 4 parts of immunopotentiator and 4 parts of choline chloride.

Furthermore, the nicotine-containing composition also comprises 40-50 parts of nicotine extract.

Specifically, the nicotine extract is prepared by drying and crushing tobacco waste and then performing microwave treatment; adding 75-90% by volume of ethanol solution for reflux extraction, and filtering to obtain nicotine extract and filter residue, wherein the filter residue is used for preparing organic fertilizer; and (3) concentrating the nicotine extracting solution in vacuum to recover the solvent, and drying, crushing and granulating the obtained nicotine extract to obtain the nicotine extract.

Compared with the prior art, the invention has the following beneficial effects:

the fertilizer disclosed by the invention is natural in raw materials, and the normal growth of shrimps in a rice field can not be influenced while the rice is fertilized. The fertilizer raw materials are recycled for wastes, and meanwhile, the natural fertilizer is non-toxic and harmless, so that the safety and the quality of the crayfish can be protected to the greatest extent. Besides, the rice fertilizer can meet the requirements of promoting the absorption of rice nutrients, improving the disease resistance/lodging resistance of rice plants and improving the disease resistance of common rice fertilizers, and can improve the yield of a rice field by about 30%. In addition, the indolebutyric acid added in the compound can promote the rapid growth of rice, the immunopotentiator can further improve the resistance of the rice, so that the compound has excellent disease-resistant and lodging-resistant capabilities even if the compound is mixed with the rice, the choline chloride is matched with other raw materials, the utilization rate of fertilizer nutrients can be ensured, the trace elements required by the rice can be provided, the compound also has the adsorption and purification effects on organophosphorus pesticides, and finally, the addition of the nicotine extract can effectively prevent underground pests, nematodes and ground pests such as plant hopper, aphid, whitefly, thrips and the like fed by a piercing-sucking mouthpart, the control effect on crop diseases and insect pests is continuous, environment-friendly and ecological, meanwhile, sufficient nutrients can be provided for the growth of crops, and the requirement of high-quality rice planting can be met.
