At present, the market for earthworm breeding has been very good in recent years. The price is higher every year, and the market is bigger every year. Of course, this industry is originally a niche project and a special breeding project, so many people don't believe that raising earthworms can still make money. There will be local agricultural technical cooperatives in every place. For example, we mainly focus on navel oranges here, and set up a special navel orange planting technology cooperative to provide planting technology training and product sales channels for growers.

You can go to the local Xinhua Bookstore for relevant information for reference. Voluntary labor, sincere learning from experienced teachers, diligent looking, asking and hands-on, can learn a lot of experience and technical knowledge in earthworm breeding. Remove the excrement of earthworms, which is called cocoon formation or turning bed, and feed it 2 -3 times a month with the thickness of 10 cm each time, so that the excrement is fresh and breathable, and the possibility of diseases brought to earthworms due to excessive accumulation of excrement is reduced. We need enough organic matter, such as cow dung, pig manure, animal manure, rotten plant leaves and other natural organic matter, and mix these natural organic matter with soil.

First dig a hole in the soil in the box, then pour the wheat bran paste into the box, mix it with the soil in the box, and finally cover it with floating soil. The advantage of covering wheat bran below is that it is not easy to ferment, and the fermentation has no odor. The pH value of earthworm manure is about 7, and the content of nitrogen, phosphorus and potassium is high, and it contains 10.5% humic acid, more than 20% organic matter, and 17 amino acids and various trace elements.

Mixed culture of earthworm and snake is also a common culture mode, and it is very popular because its culture benefit will be much higher than that of single culture of earthworm. Secondly, the living environment of earthworm and snake is almost the same. The most suitable survival temperature for earthworms is about 20 degrees Celsius, below 5 degrees, it will hibernate, below 0 degrees, it will die. And 15 degree can reproduce normally. If it exceeds 333 degrees, it will crawl away or die. Therefore, it is necessary to choose a suitable temperature environment for raising earthworms. ?
