Earthworm feed prepared by using tea leaf waste and preparation method thereof

Abstract

The present invention relates to the field of feeds and particular relates to an earthworm feed prepared by using tea leaf waste and a preparation method thereof. The tea leaves and branches are spread on the bottom of a plastic bucket, then corn meal, quicklime and cow dung are spread on the tea leaves and branches in order, the three layers are uniformly sprayed according to the order, EM liquid and water are sprayed on each of the layers, the total spraying amount of the water is 85 kg per ton of main materials and 5 kg of the EM liquid is sprayed on each of the layers. After the spreading and spraying, the mixture is sealed using plastic bags, the sealed mixture is pressed tightly, breathing holes are arranged on the plastic bag, then the mixture is fermented, the fermented mixture is subjected to stack stirring for 1-3 times after fermentation for 5-7 days, and then the stirred mixture is then fermented again to obtain the earthworm feed. The tea branches and leaves are obtained by pre-treatment, sun-drying and grinding. The EM liquid is prepared by placing the EM and black sugar into a container, and then adding water to stir the mixture evenly. The earthworm feed is simple in ingredients, cheap and easy to obtain, low in production cost and nutritionally balanced, and can speed up the production speed and reproduction speed of the earthworms, and improve the earthworm production for 30-40%.

Description

technical field [0001] The invention relates to the field of feed, in particular to an earthworm feed made from tea waste and a preparation method thereof. Background technique [0002] Earthworm is a common terrestrial annelid. It lives in the soil and comes out at night. It is of great value in environmental protection and human life. In environmental protection, it can decompose organic waste and can be described as a faithful "environmental At the same time, it can also improve the soil, accelerate the decomposition of organic matter in the soil, and restore and maintain the ecological balance of the soil; in human life, earthworms can be used as Chinese medicinal materials, commonly known as Quli and Dilong, which are cold in nature and salty in taste, and have heat-clearing properties. , Pinggan, Zhichuan, Tongluo effect. [0003] With the in-depth understanding of the value of earthworms, the earthworm breeding technology has been paid more attention. Many scholars h...

Problems solved by technology

[0004] For example, the patent number is 201410117931.X, titled "A Kind of Earthworm Feed and Its Preparation Method", which discloses the use of raw materials composed of waste fungus chaff, organic fertilizer, EM raw dew, acetic acid, urea, essence, citric acid, and salt. Fermentation treatment to prepare earthworm feed, this method is simple to operate, but the introduction of salt is not conducive to the attraction of earthworms, and the production cost of this method is relatively high

[0005] As another example, the patent No. 201310123127.8, titled "A Method for Using Pig Manure to Prepare Earthworm Feed", discloses that pig manure is air-dried or dehydrated to prepare earthworm feed. The method is simple to operate and low in cost, but the raw material is single. Nutrients are single
