Problems solved by technology

This technology is widely used in tea gardens in India and France, but few people use this technology in cold regions, mainly because there have not been a large number of earthworm varieties suitable for cold regions in Heilongjiang Province.
The red earthworms cultivated in the prior art are mainly Taiping No. 2, which mainly uses cow dung for large-scale cultivation to obtain a large number of red earthworms, crop medicinal materials, high-protein feed, fish bait, vermicompost, etc. for commercial sale. This variety is a hybrid variety , fast reproduction, high yield, but this variety does not have cold resistance, so it is not easy to be used in the bio-organic fertilizer technology of earthworms in the northern cold regions; there are also cow dung, sheep dung, and pig dung that have a long fermentation time (cow dung in cold northern regions Fermentation takes at least one summer and one winter), and not every family can obtain livestock and poultry manure at any time

Embodiment 1

[0082] Screening of the height of the worm box. The height of the worm box determines the thickness of the base material. The height of the worm box is 15cm, 20cm and 30cm. The earthworms raised in the present invention are mainly surface-dwelling red earthworms distributed in the 7-20cm soil layer. If there is too little base material, there are few earthworms to be fed, and it is easy to lose water and dry out, which will affect the growth and reproduction of earthworms and the breeding efficiency is also low, so the base material thickness less than 8cm is not within the screening range. According to breeding experience, the temperature is controlled at 20-25°C, the humidity is controlled at 55-60%, 0.8kg of earthworms are inoculated per square meter, and the weight of a single worm is 180-250mg. The base material is fermented kitchen waste, and the thickness of the base material is divided into three parts. The grades 10-15cm, 15-20cm, and 20-30cm are represented by T1, T2...

Embodiment 2

[0087] The thickness of the base material is 10-15cm, and the screening of the total weight of inoculated earthworms per square meter was carried out in the underground laboratory of the Heilongjiang Forestry Science Research Institute from January to December 2019. The earthworm species is wild red earthworm (the main species is Chiziai victory worm).

[0088] Worm box (size: 47cm×31cm×15cm), the thickness of the base material is controlled at 10cm, the temperature is controlled at 20-25°C, and the humidity is controlled at 55-60%. The base material is fermented domestic kitchen waste, according to the earthworm box Inoculate 0.5kg, 0.8kg, 1.1kg per square meter respectively, when the weight of a single worm is 180-250mg, study the effect of inoculation density on the growth and reproduction of earthworms, 3 weeks is a reproduction cycle. During the reproduction process of earthworms, the biomass of earthworms was investigated once a week, and the effect of inoculation density ...

Embodiment 3

[0100] The thickness of the base material is 10-15cm, and the effect of the ratio of adding fresh organic waste each time to the total weight of the initial inoculated red earthworm on the reproduction of wild red earthworm. Earthworm breeding box (specification: 47cm×31cm×15cm), the thickness of the base material is controlled at 10cm, the temperature is controlled at 20-25°C, the humidity is controlled at 55-60%, 0.8kg seed worms are inoculated per square meter, and the weight of a single worm is 180mg- At 250mg, study the digestion rate of adding fresh organic waste within 7 days. The base material is fermented kitchen waste. The effect on the growth and reproduction of earthworms. 3 weeks is a reproduction cycle.

[0101] Because the fresh organic waste will be corrupted and moldy after a long time is unfavorable to the growth and reproduction of earthworms, the present invention adopts a growth cycle (21 days to change the base material) and feeds the fresh organic waste t...

Abstract

The invention discloses a method for breeding wild red earthworms in northern cold regions by using domestic kitchen garbage. The method comprises the following steps of collecting the wild red earthworms in the cold regions; preparing base materials of the wild red earthworms in the cold regions; preparing a site; preparing earthworm feeding boxes; preparing the base materials; preparing nutrient materials; determining earthworm inoculation density; executing an earthworm feeding method, specifically, adopting a feeding box side feeding method; collecting the wild red earthworms from May to October every year, and putting the sexually mature red earthworms into different earthworm boxes respectively; regularly putting seed earthworms in all the earthworm boxes into a large container for mixing every year, and then inoculating 0.8-1.1 kg of earthworms per square meter according to the thickness of the base materials of the earthworm boxes of 10-15 cm; and continuously using the seed earthworms for 2 years, and eliminating and updating the seed earthworms after 2 years. By adopting the structure, the method for breeding the wild red earthworms in the northern cold regions by by using the domestic kitchen garbage is simple, convenient, environment-friendly, practical and effective, and the bred wild red earthworms in the cold regions are enough for a family farm to carry out soil improvement.

Description

technical field [0001] The invention relates to the technical field of a breeding method for wild red earthworms in cold regions used in northern earthworm bio-organic fertilizer technology, in particular to a method for breeding wild red earthworms in northern cold regions with domestic kitchen waste. Background technique [0002] The main feature of bio-organic fertilization (FBO) is the use of natural fertilization mechanisms to manage soil, crops and forests. Practice has proved that this technology can not only increase the yield of tree plantations, but also maintain biodiversity and soil fertility. This technology is widely used in tea gardens in India and France, but few people use this technology in cold regions, mainly because there have not been a large number of earthworm varieties suitable for the cold regions of Heilongjiang Province. The red earthworms cultivated in the prior art are mainly Taiping No. 2, which mainly uses cow dung for large-scale cultivation...
