(Original title: These four agricultural projects will receive subsidy funds this year)
Four types of circular agriculture models will be launched in 2017
[ China Agricultural Machinery Industry News ] As we all know, China's agricultural pollution problem is relatively serious. Since the central government encouraged green mountains and green water to develop agriculture, from this year on, the state's support for eco-friendly circular agriculture has suddenly increased, and the country has implemented zero growth of chemical fertilizers. In the case of low-toxic pesticide pilots, only one biogas tank was built, and the state invested 500 billion. Today, Xiaobian will introduce you to four kinds of circular agriculture models for your reference.
Four types of circular agriculture models will be launched in 2017
Comprehensive utilization mode of livestock and poultry excrement
â—Ž comprehensive utilization of biogas
We will carry out research and demonstration and promotion of biogas residue and biogas slurry ecological recycling technology, and promote the “pig-marsh-fruit (vegetable, grain, mulberry, forest)†cycle mode, and link up the aquaculture industry and the sub-planting industry.
â—ŽManure collection and treatment and organic fertilizer processing and utilization
Establish a collection mechanism for livestock manure collection, village transportation, and film collection, and develop organic fertilizer.
Stereo composite loop mode
â—Ž "mulberry branches - black fungus - rice" cycle mode
Using the trimmed mulberry branches, grinding into powder is used as a nutrient base for planting black fungus. After the production of black fungus, the slag is used as organic fertilizer to return to the field and fertilize the soil.
◎ “Mobile shed ecological chicken raising†circulation mode
Set up a simple greenhouse to raise chickens in the vegetable fields, and implement chicken-vegetable-rice rotation. This kind of ecological cycle mode can save land resources; secondly, reduce operating costs; third, it is conducive to chicken disease prevention and epidemic control; fourth, it is conducive to improving chicken quality; fifth, it can effectively increase land fertility and reduce environmental pollution. .
â—Ž "Fish - mulberry - chicken" mode
Fish are raised in the pond, mulberry trees are planted around the pond, and chickens are raised in the mulberry garden. Fish pond silt and chicken manure are used for mulberry manure, silkworm cocoons and mulberry leaves are fed to chickens, and silkworm manure is fed to fish, so that mulberry, fish and chicken form a good ecological cycle.
Breeding symbiotic ecological cycle
â—Ž "fish symbiosis" mode
The "fish carp symbiosis" means "é³…, è—•", "甲鱼, è±", "锦鲤, è—•" and other ecological recycling modes are a kind of mixed cultivation mode of raising aquatic products such as loach and soft-shelled turtle in Putian.
The large amount of excrement produced after eating such as loach is decomposed and mineralized as a fertilizer for the lotus root to absorb and use, which promotes the growth of lotus root, and at the same time reduces the poisoning caused by the deterioration of water quality to the loach, promotes the healthy growth of loach, and the potential of loach. Drilling mud and other activities have played a role in continuous cultivating and loosening soil, which is conducive to the growth of lotus roots; the pests in the shoal are not only high-quality active bait for loach, but also play a role in biological de-worming for Putian.
â—Ž "rice-duck farming" and "rice-fish breeding" cycle model
Make full use of the rice field resources, and after the rooting of the rice seedlings, put a certain number of young ducks or fry in the rice fields to play the role of ecological recycling and increase benefits.
On the one hand, pests and weeds in rice fields can be used as duck feed or fish bait to reduce pest and pesticide application; on the other hand, duck or fish excrement can be directly returned to the field to increase fertility and reduce fertilizer application in paddy fields. , reduce costs and increase efficiency.
Cycle model with straw as a link
The promotion of the straw returning mode can effectively achieve the ecological cycle goal of reducing incineration emissions and increasing farmland fertility.
In addition, there are many agricultural recycling models with straw as the link, such as the comprehensive utilization of straw feed, fuel and base materials, and the construction of “straw-based materials-edible bacteria†and “straw-forming fuel-fuel-farmersâ€. ", straw - silage - aquaculture" industrial chain.
This model can realize the step-by-step utilization of straw resources and zero pollutant discharge, make the straw waste resources be used reasonably and effectively, solve the problem of environmental pollution and waste of resources caused by arbitrary disposal of straw, and obtain organic fertilizer, clean energy and bio-based. material.
Green development and building a resource-conserving and environment-friendly society are the goals that China's current industries are striving for under the current environmental pressure. At present, the national support focus has been very clear: eco-circulating agriculture will be the national support focus during the 13th Five-Year Plan period, and the relevant national special funds will also increase. It is recommended that qualified enterprises and cooperatives prepare for relevant projects.
