In recent years, many places have been exploring condominium models. Among them, the lichen is a more mature model. These integrated and efficient ecological models have not only been effective in improving the field's ecology, improving its quality and length, but have also had a significant impact on the reduction of pests and pest hazards, while increasing the benefits of yellow and mud farming. Today, one thing about farming is to take stock of the experience of multi-field farming and share it with the big guys。

I. Integration of those
The water sources in the fields shall be sufficient, clean, easy to drain and drain, and the soil shall be estranged in an area of 1. 5 to 2 acres. There are about 1 to 2 m wide, 0. 4 to 0. 5 m deep gutters, with four pits around the gutter or four corners, each of which covers 8 to 10 m2 and 0. 8 m deep, so that the bottom of the pond can be covered by 0. 3 m fat mud; the field is covered by 0. 5 m wide and 0. 4 m deep ditches, with cross-sections of the gutters, pits, which cover about 15 to 20 per cent of the acreage; the pits are covered by pottery, bamboo canisters, etc., which provide a shelter for yellow and mackerel, so as to prevent the run-off of gusts and gusts, which can be covered by bricks。

Ii. Preparation of ponds
1. Cleaning ponds
Before the chrysanthemum, the water was sterilized with raw lime and the amount used was 70 kg/acre。
2. Fat bait
The fermented poultry and animal manure can be used 10 days before the seeding of the fermented species to produce plankton for fermentation and gill feeding at 250 - 300 kg/acre and to add 0. 3 m water。
Yellow and mud seeding
Iii. Cultivation
1 equivalent to 30-40 g end/end with a drop density of 0. 2-0. 3 kg/m2. Late in mid-may, the water temperature was 15°c, which was dropped in the clear sky. 4 per cent of salt water is immersed prior to release。
2- speculation 60-80 tails/kg, or about 40 per cent of the species。
Iv. Contribution
1. Set up a table to make a contribution in the evening. When temperatures and air pressure are low, the appetite is affected, with a modest amount of input, and when the weather is good and the temperature is high, it is appropriate that the following morning the bait is not left behind。
2. Feeds are based on home-grown earthworms, with a contribution of 4 to 6 per cent. With regard to earthworm farming, you may refer to the following articles。

3. In order to improve the appetite for yellow beverages, earthworms may be crocheted first, and may be replaced with worms such as mackerel, thallium, snail, shrimp, etc., supplemented by vegetable feed such as pasta, rice, melon fruit peels。
In the months of april, may and october, several energy-efficient black lights could be mounted on top of the ditch pit. At night, insects are lured in order to be yellow bait。
5. The mud eats yellow oxen residues, faeces, and natural baits in the field。

V. Daily management
Early in the morning and in the evenings, each of the fields was patrolled to observe the growth of the luminous, luminous and lurch and to remove the risks of leakage。
2. Water levels are required to grow according to the requirements of the lichen and are drained in a timely manner during the rainy season, and are protected against rats, water snakes, poultry, etc. Entering the field for the purpose of feeding the larvae。
3. The field should be ventilated and too many lichen leaves should be removed in time。
4. It is desirable that the zhangdas maintain micro-flows of water at a speed that is not too high, so that they do not cause the yellow plume to swim against the water and cause physical effort。
In summer, water is exchanged for two times/month, and in the middle of the afternoon, the temperature difference should not exceed 2°c。
In summer, to reduce water temperature, ditches, pits and other aquatic plants, such as hydroponics and peanuts, can be planted in appropriate quantities。

Vi. Disease control
The low incidence of disease is sustained by the fact that the density of lactation is not too high。
2. Toads can be fed in the field, where they are soaked, and have a disease-preventable effect。
3. Feeds are kept fresh and clean, and are regularly fed with appropriate amounts of cholesterol acid, fungi, etc., to enhance the body of gills and gills。
4. There are too many leeches, which can be controlled by lime water or induced by pig blood。

Vii. Receiving in time
In january and august, the harvest period was completed。
In february and early october, a series of raids began and were completed by the end of december。
3. The harvest of the dead is sustainable until the end of april of the following year and can be accompanied by the harvest of the land during the winter season and the capture of the yellow and mud。
