How to breed earthworms

The method of orchard culture: in the open space under the fruit tree, the rotten farm manure was accumulated along the tree line to make a breeding bed for breeding. Bomb shelter farming: that is, farming is carried out in the basement, and lights are needed at night to prevent escape and promote growth. Mulberry breeding method: digging grooves along mulberry rows and applying organic fertilizer for culture. Feed field culture: irrigation and drainage ditches are opened in the feed land, organic feed can be applied in the grooves, and then dragons are put in and covered with soil. Vegetable garden culture: after the seedlings are unearthed, they can be put into the ground dragon.

1. Orchard culture method

1. The ground dragon can be raised in the open space under the fruit trees, which can not only make full use of the land, but also promote fruit production.

2. For example, the culture method of Qingdilong is similar to that of mulberry garden. If the red dragon is raised, the mature cow, pig and horse dung, which is 1.5-2m wide and 0.4m high, can be accumulated under the fruit tree, that is, the breeding bed of the red dragon.

3. A walkway needs to be left in the middle of each breeding bed, and a drainage ditch can be opened every 2 breeding beds. The feed surface of the breeding bed can be covered with straw or wheat straw to keep the humidity at 60-70%. It can be covered with plastic film on rainy days to prevent Rain Water from soaking.

Second, culture in air-raid shelter

1. The city air-raid shelter is actually the basement, which is more suitable for breeding red dragons. The surrounding humidity is relatively high, warm in winter and cool in summer. The breeding method is the same as that of box culture and pit culture.

2. Lights can be lit at night, which can not only prevent escape, but also have a certain light source that is more conducive to the growth of ground dragons.

Third, mulberry garden culture method

1. Mulberry fields with relatively flat terrain and good drainage and irrigation conditions can be dug 40cm-wide and 20-25cm deep along mulberry rows, and initially mature organic fertilizers, such as pig and sheep dung, withered leaves, rotten grass, horse and cow dung, straw, weeds and so on, can be applied.

2. About 5000-7500 kg of organic material is applied per mu, and then the soil is covered with 10-15cm, which can be put into the ground dragon for breeding, and the quantity can be determined according to the size of the soil dragon and individual.

3. Green manure or green fodder can be planted between rows, and a ditch can be opened every 5 rows, and the water content should be kept at about 30%.

IV. Feed field culture

1. Can be cultivated in the cultivation of aggregate grass, broad beans and other perennial green forage land, you can choose flat fodder land, about every 10 rows can open an irrigation and drainage ditch.

2. Between the rows of polymeric grass, the grooves with 15-20cm in width and depth can be opened, organic feed can be applied in the grooves, and then the soil around 10cm can be covered on it, and it can be put into Qingdilong culture.

3. Pay attention to regular drainage and irrigation or drainage, so that the soil water content is about 30%.

V. vegetable garden culture

The main results are as follows: 1. The water and fertilizer conditions of the vegetable garden are sufficient, and the management is relatively fine, which is more conducive to the growth and reproduction of the dragon.

2. About 7500-10000 kg of high-quality organic fertilizer and rotten vegetables and garbage can be applied per mu in the vegetable garden of breeding dragons.

3. After the vegetable seedlings are unearthed, the earthworms can be put into cultivation. When breeding in the vegetable garden, the application of chemical nitrogen fertilizer and some pesticides should be reduced as much as possible.

4. When it grows up, it can be harvested by stages combined with vegetable management.
