Key technical points of self-breeding and self-feeding management of snakes
Snake self-breeding technology should pay attention to the following points: first, species selection: every spring, strong, fat female snakes should be selected as species, regardless of venomous snakes or non-venomous snakes, generally lay eggs from late June to July. Female snakes should be fed nutritious and calcium-rich food before and after spawning, so that they can eat and drink as much as possible. There is no need to consider whether female snakes mate or not. female snakes can produce fertilized eggs for five years at a time. Second, hatching: in order to prevent the snake eggs from drying up and sinking, the snake eggs produced should be put into the incubator in time for artificial hatching, be sure to maintain the temperature and check regularly.

Experience of raising mandarin fish with self-breeding live bait
Last year, the area of mandarin fish culture in Wujiang City has exceeded 10,000 mu. Zhang Qifang, an expert in mandarin culture in the sixth division of East Taihu Aquaculture Farm, raised mandarin fish in 20 mu in 1999, and the matching ponds were 83.5mu (of which 44 mu were recultured green shrimp). The yield of mandarin fish per mu was 613kg, and the benefit per mu was 3163 yuan.

On the self-breeding technology of snakes
In March, the temperature picks up and the snake becomes active. In the snake room of Leicun Snake Farm, there are shiny black snakes, each 0.3 jin each, all small snakes hatched last year, and every staff member's face is covered with smiles of hope. Some Chinese and foreign scholars once thought: "it is impossible to raise snakes successfully, let alone hatched young snakes." after 17 years of repeated exploration and practice in Leicun Snake Farm, the dream has come true three years ago, from young snakes to more than one kilo.

Take the measures of "three exchanges" to increase the yield of Gastrodia elata
Gastrodia elata is a good traditional Chinese medicine, which has been selling well in the market in recent years. The majority of farmers in Chalu Village, Baoshan Town, Fengcheng City, Liaoning Province regard the development of Gastrodia elata production as an important way to get rich. more than 40 farmers in the village plant Gastrodia elata and have considerable income every year. Li Jingrong, a retired cadre in the village, has planted Gastrodia elata for 14 consecutive years and has accumulated a wealth of experience. He found that the yield of cultivated Gastrodia elata decreased year by year. There are three main reasons: first, due to the serious degradation due to the use of self-propagating and self-bred flax seeds every year, and second, due to the continuous use of self-propagating and self-breeding strains.

Characteristics and cultivation techniques of 29 you 559, a new high-yielding hybrid rice combination
29 you 559 is a new indica three-line hybrid rice combination bred by Jiangsu Xuzhou Biological Engineering higher Vocational School and Jiangsu Coastal Agricultural Science Institute with self-breeding male sterile line 29A and self-breeding restorer line Yanhui 559. 29A is the first indica three-line male sterile line bred in Jiangsu. The new combination 29 you 559 bred with 29A and Yanhui 559 had obvious heterosis and passed the crop variety approval in Jiangsu Province in January 2003. The heterosis of Zhong 29 you 559 showed in 1999 and participated in the cross in Jiangsu Province.

Experimental study on Industrial Rapid Propagation of Potato Test-tube plantlets
For many years, due to the self-breeding and self-breeding of farmers, the yield of potato decreased year by year, the quality became worse, the shape of the product became worse and so on. It has been proved by scientists that virus infection and its accumulation in potato blocks are the main reasons for potato "degradation". In order to solve the problem of serious degradation and yield reduction of main potato varieties in our city, our institute took potato virus-free production as a key experimental subject, and carried out experimental research on the problems existing in virus-free production, so as to make use of resources and reduce production costs.

Prevention of porcine erysipelas
(1) eliminate the source of the disease: the pigsty is often disinfected regularly with 10% stone from the milk, at least 2-3 times a year. (2) eliminating transmission factors: the disease in many pig farms is caused by buying pork from outsources. therefore, self-breeding is the key to prevent porcine erysipelas. (3) to improve the resistance to pig disease: as long as pigs are properly fed and managed, fed more green feed, exercised properly, padded sheds are raised every day, the health status of pigs is checked every day, and diseased pigs are isolated and treated in time.

How to grow spring potatoes
There are three ways of early ripening cultivation of potato in spring: double film mulching in plastic film small arch shed, thick film small arch greenhouse mulching and plastic film laying. The potato cultivated by these methods can be put on the market 10 to 20 days earlier than that cultivated in the open field. No matter what kind of mulching method is adopted in the selection of improved varieties, the original varieties of Dongnong 303 or Kexin No. 4 transferred from the northeast must be selected, not self-retained species, let alone native species with self-breeding for many years, aging varieties and serious degradation of species. The amount of seed used per mu is about 150 kg, and the sweet potato can be cut and sown, each seed.
