Problems solved by technology

Ningxia is extremely hot in summer, with long sunshine hours and strong solar radiation. It is extremely cold in winter with short sunshine hours. It is a typical "cold winter and hot summer". The highest temperature in July is between 27°C and 41°C, most of which are at 32°C Above, the average minimum temperature in January is between -8°C and -16°C. Within this temperature range, the growth of earthworms is restricted. If you do not take any preventive measures in open field cultivation, earthworms will die, especially in the coldest winter. The lowest temperature during this period was above -10°C, which directly led to the death of earthworms
Based on the limitations of the above-mentioned climatic characteristics, the development of the earthworm industry in Ningxia is seriously restricted.

Embodiment 1

[0045] Step 1. Take 70% cow dung, 20% straw and 10% bean dregs and inoculate and ferment for 25 days. After decomposing, the pH is 6.5 to make bait. The straw includes 50% crop straw, 30% weeds and 20% sawdust . After the fermentation of the bait is completed, the long and narrow row method is used to build a long strip-shaped worm bed. The worm bed is 1.2m wide, the wide row spacing is 2m, and the narrow row spacing is 0.6m. Complete; lay a sprinkler irrigation pipeline on each ridge bedworm bed, the main pipeline perpendicular to the earthworm bed adopts a 40cmPE pipeline, and the branch pipeline extending in the extension direction of the earthworm bed adopts a 30cm sprinkler hose with a nozzle aperture of 0.5mm; the working pressure of the micro-spray is set 0.3MPa;

[0046] Step 2: put vermis species, the amount of feeding is controlled at about 5000 pieces / m 2 , add a bait every 21d, add thickness to be 12cm, every 60d the earthworm bed is loosened, every 7d spray a nu...

Abstract

The invention discloses an earthworm open field breeding method in the Ningxia region. The method includes the steps of oversummer management, wherein a straw curtain with the thickness of 2-3 cm covers a built earthworm bed, proper watering is used for controlling the temperature of the earthworm bed to be 10-30 DEG C and the relative humidity to be 60-70%, the straw curtain is formed by weavingmultiple layers, and natural porous materials are wrapped in the multi-layer straw curtain; overwinter management, wherein in the last ten-day period of October, bait with the thickness of 30-50 cm islaid on the earthworm bed, after proper watering, a drainage ditch is dug and covered with four layers of covering objects from bottom to top, the first layer is a waste EVA shed film making direct contact with the bait, the second layer is a straw curtain with the thickness of 5-10 cm, the third and four layers are waste EVA shed films keeping the temperature of the earthworm bed to be 10 DEG Cor above, and a high heat absorption layer is arranged between the third and fourth layers of waste shed films. The survival rate, disease resistance, growth speed and average weight of earthworms bred through the earthworm open field breeding method are all improved, the quality and yield of the earthworms are improved, and the soil improvement effect is remarkable.

Description

technical field [0001] The invention relates to the field of earthworm breeding methods. More specifically, the invention relates to a method for cultivating earthworms in the open field in Ningxia. Background technique [0002] Earthworm is a mollusc with juicy soft body and 70% protein content. It is called "Earth Dragon" in traditional Chinese medicine. Earthworm is cold in nature and slightly bitter in taste. Efficacy, it is a traditional Chinese medicine; in addition to being used as a medicinal formula and prepared as a Chinese patent medicine, Dilong also contains rich biologically active components. Using modern biotechnology, it can be extracted and developed into multi-faceted medicines and health products, and can be applied In animal feed, in animal husbandry, earthworm is used in agricultural planting as organic liquid fertilizer. [0003] Ningxia has good soil conditions, air quality and sufficient materials. These natural conditions have created favorable co...
