How to scientifically manage film-mulched garlic after it turns green
The weather is gradually warming up, and film-mulched garlic has now begun to turn green. After the seedlings turn green, adventitious roots begin to grow at the lower part, accumulating nutrients for the differentiation of garlic scapes and bulbs, which is the key period for achieving high quality and high yield of garlic. The management measures for this period are: clean the dust off the plastic film. Due to irrigation before winter, dust or silt will accumulate on the garlic film, affecting its light transmission, so it should be removed as early as possible to enhance light and raise soil temperature. Repair damaged plastic film in time. Film that has been torn, scratched, or lifted by the wind should be repaired at any time, and garlic sprouts curled under the film should be hooked out as soon as possible

The new high-quality conventional rice variety Yexianzhan No. 8 was bred by the Huizhou Municipal Institute of Agricultural Sciences in Guangdong.
Yexianzhan No. 8 was bred by the Huizhou Municipal Institute of Agricultural Sciences in Guangdong through the cross of Guiyizhan No. 2 / Texianzhan 13 // IR24. In 2002 and 2003, it took part in the late-season regional trial of the high-quality group in Guangdong Province, with average yields of 405.91 kg and 454.47 kg per mu, increasing yield by 10.64% and 9.25% respectively compared with the control variety Jingxian 89, and both yield increases were extremely significant. In 2003, it took part in the provincial production trial in the late season with an average yield of 446.7 kg per mu, an increase of 7.48% over the control. The rice quality was tested and identified by the Food

A Complete Analysis of Scientific Management Methods for Snake Farms Throughout the Year
Snakes are ectothermic animals, and their body temperature changes as the ambient temperature rises and falls. Good management of a snake farm can ensure normal growth and reproduction of snakes and improve snake yield and quality. For spring management, spring is generally the most suitable time to introduce snakes for breeding, as there is no need to worry about the weather being too cold or too hot during transport, and the egg-laying period also occurs at this time. Before introducing snakes into the snake farm, the area should be cleaned in advance, and cleaning and disinfection work should be done well. Newly emerged from hibernation, snakes basically do not eat for the first 2 to 3 weeks, begin to eat a small amount of food in April, and in May their food intake

Detailed Explanation of Feed Sources and Scientific Feeding Methods for Raccoon Dogs
1 Feed Sources 1.1 Legumes Except for poisonous fish such as pufferfish, most marine and freshwater fish can be used as feed for raccoon dogs. In addition to high protein content, fish also contain fat, vitamin A, vitamin D, and inorganic salts. Their digestibility is almost the same as that of meat, and the energy content varies greatly depending on the fish species. Fresh fish fed raw has higher nutritional value than cooked, but some marine fish and most freshwater fish contain thiaminase, which can destroy vitamin B1. Long-term raw feeding can easily cause vitamin B2 deficiency.

How to Feed a Nursing Mother Dog? A Detailed Guide to Scientific Feeding Methods
The first milk a mother dog produces after giving birth is called colostrum. Colostrum contains a variety of nutrients and can protect the puppies against viruses or other infectious diseases, so it is very important to let every puppy drink colostrum. If the mother dog does not have enough milk to feed her puppies, the dog owner must use a bottle to feed a supplement specially formulated for puppy nutrition. In addition, a nursing mother dog needs sufficient nutrients to replenish her milk supply, and at the same time, a complete diet must be prepared for weaned puppies; your veterinarian can provide the best feeding plan for all of this.

Detailed Explanation of Key Points of Scientific Chemical Regulation Technology for Cotton
Chemical regulation must be flexibly applied according to cotton growth conditions and weather conditions, focusing on vigorously growing cotton fields; when the soil is short of water and cotton growth is inhibited, it should be used sparingly or not at all. For cotton fields showing a tendency toward excessive growth at the full bud stage and early flowering stage, use 1.5-2.5 grams of mepiquat chloride per mu, diluted in 20-35 kg of water for spraying. For vigorously growing cotton fields at the full flowering stage, use 2-3.5 grams of mepiquat chloride per mu, diluted in 30-35 kg of water, sprayed on the surface of the cotton plants to control plant growth, so that the daily growth of the main stem is kept below 3 cm

Scientific Methods for Feeding Cotton Stalks to Ruminant Livestock
With the current year-on-year increase in cattle and sheep populations, along with large-scale land development and cultivation, the original grazing pastures have sharply decreased. Therefore, solving the winter and spring forage problem for cattle and sheep is the primary issue for developing animal husbandry on all farming and herding farms. Faced with large areas of cotton stalks after picking is complete, livestock raisers can only follow the old method of letting cattle and sheep loose in the fields to graze freely, resulting in massive resource waste. In order to better utilize cotton stalks and achieve the effect of returning them to the field through the animal's digestive tract, a set of scientific methods for feeding cotton stalks to ruminant livestock has been summarized. After trial feeding and observation by livestock raisers on our farm

Scientific Feeding Methods and Precautions for Pregnant Dogs
The gestation period of dogs is 58~64 days, with an average of 62 days. During pregnancy, the task of feeding and management is to strengthen the physique of the mother dog, ensure the healthy development of the fetuses, prevent miscarriage, and ensure that each litter can produce numerous, robust, lively puppies with a large birth weight. For this reason, in the feeding and management of pregnant mother dogs, in addition to providing a complete daily ration, the feed must be hygienic and of guaranteed quality. Never feed moldy, spoiled, deteriorated, toxic or strongly irritating feed, to prevent miscarriage. The feed must not be changed frequently

How to control wheat aphids more scientifically? A detailed guide to practical methods
Wheat aphids are the type of pest with the largest annual occurrence area and the most severe damage in wheat. Although wheat aphids occur and cause damage year after year, farmers still have some misunderstandings in their control. How can wheat aphids be controlled more scientifically? It is recommended to pay attention to the following three points: 1. The appropriate time to start control. In general years, the appropriate time to start controlling wheat aphids (when the number of aphids per 100 plants rises to 500) is after wheat flowering (before grain filling), generally around May 5. Starting control at this time is best. As long as the right pesticide is used and the dosage meets the requirements, generally one control treatment can solve

A detailed explanation of the guidelines for the use of pollution-free fishery drugs: scientific medication is safer
Although fishery drugs can treat diseases of the farmed fish, shrimp and crabs, because aquatic products will ultimately be placed on people's dining tables, attention must be paid to the safety of the drugs used to prevent and treat their diseases. To prevent harmful substances contained in aquatic products from harming human health, the Food Hygiene Law stipulates that aquatic products such as fish, shrimp and crabs must not contain antibiotics or synthetic antibacterial agents or other substances harmful to human health. To prevent drug residues, it is necessary to understand the correct methods of drug use and the withdrawal period. The relevant national authorities have issued the "Pollution-Free Food
