Embodiment Construction

[0014] Taking the corn stalk-oyster mushroom-chicken (egg)-leek selenium-enriched production system as an example, the specific steps are as follows:

[0015] 1. Crush the corn stalks, add urea 10g / kg, sucrose 5g / kg, superphosphate 2g / kg, gypsum 1g / kg, sodium selenite 20-50mg / kg, adjust the moisture content to 60%-70 %, the pH is 6.5-8.0, and the fermentation is carried out, and sodium selenite can also be added after fermentation to obtain a selenium-enriched fermentation substrate.

[0016] 2. Put the fermented selenium-rich fermentation substrate into the cultivation bag for inoculation. The cultivation bag is generally made of polyethylene or polypropylene plastic bags, and different specifications are used in different seasons: optional in late summer and early autumn (20-22) cm × (40-45) cm size, (24-25) cm × (45-50) cm size can be used for autumn cultivation, (25-26) cm × (50-52) cm size can be used in late autumn and early winter, winter (25~29)cm×(50~55)cm can be sel...

Abstract

The invention provides a production system of a selenium-enriched product based on recycling ecological agriculture. Selenium is added into crop straws and livestock manure to ferment, or selenium is added after fermenting to obtain selenium-enriched ground substance; the ground substance is used for planting edible fungi to ensure that the selenium content in the edible fungi can be increased obviously; edible fungi residual is used for cultivating earthworms; selenium-enriched earthworms are obtained to serve as feed or feed additives for feeding pigs, chicken, ricefield eels, turtles and the like so as to obtain selenium-enriched meat, eggs and fish products. Wormcast and livestock manure are used for planting vegetables such as leeks, cucumber and the like or field crops, such as corn, wheat and the like to further utilize selenium to obtain selenium-enriched vegetal products; plant residues obtained in planting vegetables or field crops can be added with parts of selenium to serve as the ground substance for planting edible fungi or directly feeding earthworms; thus, the invention fully utilizes resources in a recycling manner, and has obvious economic benefit, ecological benefit and social benefit.

Description

1. Technical field: [0001] The invention relates to a production system of selenium-enriched products based on circular ecological agriculture, belongs to the field of circular ecological agriculture, and is a production system for recycling and efficiently utilizing crop straws and livestock manure. 2. Technical background: [0002] my country is a large agricultural country, and the annual production of crop straw reaches 500-700 million tons, which is a very valuable resource. However, the current situation of straw utilization in my country is unsatisfactory. A large number of straws are burned, causing serious environmental pollution. In rural areas, a considerable number of straws are discarded at random, which cannot be fully utilized, and seriously affects the ecological environment in rural areas. Therefore, making full use of straw will not only help protect the ecological environment, but also increase farmers' income. [0003] With the continuous expansion of th...
