In recent years, with the implementation of the national agricultural machinery purchase subsidy policy, the majority of rural tractors have developed rapidly. However, many aircraft operators lacked a correct understanding of the tractors, resulting in increased breakdowns in locomotives and increased repair costs. These "misunderstandings" in use mainly include the following aspects: First, recognizing contempt, accidents occur frequently. Some operators mistakenly believe that tractors are simple in structure and slow in speed. Most of them are driven on rural roads where people and vehicles are scarce. Therefore, it is considered that tractors do not have to be carefully maintained and operated, and that there is something wrong with them. Speeding, overloading, and overcrowding are even more serious. Homely meals. However, due to its simple structure, it determines that its driving performance is not as sensitive, complete, and reliable as a car. Therefore, contempt is the root cause of multiple tractor safety accidents. The second is that the wear is not in place and the life span is greatly reduced. Some operators mistakenly believe that the trial run-in operation is an undeniable move. Buying a new car or overhauling a locomotive is not without running-in, or it will take a few laps and go hastily. As a result, the wear of the parts is accelerated, the faults are increased, the benefits are reduced, and even the cast suffers. The third is that the lubrication is not on time and the wear is increased. The lubrication of various parts of the locomotive can not be carried out on time or by location, often neglecting some lubrication points that do not immediately show faults, and over time will lead to major problems. If the lubrication parts of the oil pan, air filter, etc. cannot be filled with oil on time, serious mechanical accidents may occur. Fourth, it is not worth the candle. In order to save money, some drivers use scrapped or unqualified accessories for use. If someone puts used oil back into the hydraulic system, the result is hydraulic malfunction and other problems that are actually not worth the candle. The fifth issue is that fuel increases regardless of season. Some operators use the same brand of lubricating oil regardless of winter or summer. This is not only uneconomical, and it even prevents the machinery from being effectively lubricated. It is always difficult to start a tractor with one hand. After inspection, there are no problems with the system such as gas distribution and fuel. After the inquiry is difficult to start in winter, spring and summer is easy, hot car is easy, cold hard. The problem was ascertained. In the winter, oil is still used in the summer. The viscosity is large and the resistance is large, so it is difficult to start. In recent years, with the improvement of people's living standards, the demand for Huangqi has continuously increased. The farmers' artificial breeding technology of Huangqi has also been continuously improved, and the considerable economic benefits have been obtained.
Vitamins:
Vitamin A:
Retinol. Carotene compounds responsible for transmitting light sensation in the
retina of the eye. Deficiency leads to night blindness.
Beta carotene: An
antioxidant which protects cells against oxidation damage that can lead to cancer.
Beta carotene is converted, as needed, to vitamin A. Food sources of beta
carotene include vegetables such as carrots, sweet potatoes, spinach and other
leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive
carotene in the diet can temporarily yellow the skin, a condition called
carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1:
Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a
disease of the heart and nervous system.
Vitamin B2:
Riboflavin, essential for the reactions of coenzymes. Deficiency causes
inflammation of the lining of the mouth and skin.
Vitamin B3:
Niacin, an essential part of coenzymes of body metabolism. Deficiency causes
inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6:
Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the
skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic
acid): Folic acid is an important factor in nucleic acid synthesis (the genetic
material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An
essential factor in nucleic acid synthesis (the genetic material of all cells).
Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C:
Ascorbic acid, important in the synthesis of collagen, the framework protein
for tissues of the body. Deficiency leads to scurvy, characterized by fragile
capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A
steroid vitamin which promotes absorption and metabolism of calcium and
phosphorus. Under normal conditions of sunlight exposure, no dietary
supplementation is necessary because sunlight promotes adequate vitamin D
synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone
deformity (rickets) in children.
Vitamin E:
Deficiency can lead to anemia.
Vitamin K: An
essential factor in the formation of blood clotting factors. Deficiency can
lead to abnormal bleeding.
Nutritions:
For the treatment
of nutritional disease, any of the nutrient-related diseases and conditions
that cause illness in humans. They may include deficiencies or excesses in the
diet, obesity and eating disorders, and chronic diseases such as cardiovascular
disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also
include developmental abnormalities that can be prevented by diet, hereditary
metabolic disorders that respond to dietary treatment, the interaction of foods
and nutrients with drugs, food allergies and intolerances, and potential
hazards in the food supply. All of these categories are described in this
article. For a discussion of essential nutrients, dietary recommendations, and
human nutritional needs and concerns throughout the life cycle, see nutrition,
human.

First, the construction of Huang Yu Chi In order to better the breeding and protection of Astragalus, first of all, to build a suitable environment for its growth. Because Huangqi likes to grow in the mud of many organic acids, the general pool area is 40 to 50 square meters, and the depth of the pool is about 1 meter. There are inlets and outlets, and the shape is based on local conditions. Most of them are rectangular and square. The bottom of the pool and the walls should be sturdy with bricks and cement to prevent the jaundice from escaping through the hole. The bottom of the pond should be set about 30 centimeters deep. The pool simulates the natural environment as much as possible. For example, if the pool is covered with rocks as much as possible, the root of the tree will make the astragalus to live in the crevices or gaps in the roots. The water should not be too deep, about 20 centimeters, which will help the yellow pelican breathe. The pH should be adjusted between 6.5-6.8, and some aquatic plants can be placed in the pool.
Second, the selection and placement of the yellow peony seedlings The best choice for the investment is to purchase artificially propagated yellow peony seedlings or to purchase natural seedlings. Jasmine has a strong body, smooth body surface, no mucus, active and lively movement, deep yellow body color, bright and no scars, uniform specifications, stocking density and specifications, large specifications, small stocking density, such as 25 grams per square meter Cubs can be placed between 100 and 120 tails. Before entering the pool, apply 2% to 3% concentration of saline or 100 mg, and kilograms of potassium permanganate to wash for more than 10 minutes to disinfect the carcasses. The temperature of the disinfectant should be the same as the temperature of the pool water, and there should be no temperature difference. Huang Yu Chi has to be disinfected, generally with 50-100 grams per square meter of calcined water Quanchiposa, 1 week after the delivery of yellow peony seed.
III. Feeding and management of Astragalus
1. Astragalus's dietary jaundice is an animal-based omnivorous fish that can be fed with quail, quail, fly maggots, small fish, shrimp, and snails, or other animal waste. It can also be fed with a small amount of wheat gluten, leaves, and vegetables. Melon peel and so on. However, it is important to note that the yellow eel eats fresh bait, and rotten spoils do not feed it.
2. Do not feed bait after the feed has been put into the pond for 3 days. After 3 days, it is OK to invest in baicalin. Astragalus has the habit of feeding at night, and the feeding time may begin in the evening, after which the feeding time is gradually advanced. After a period of domestication, the feeding may be fixed at 10:00 or 3:00 pm.
Feeding amount should be changed according to the change of water temperature. The optimum temperature for the growth of Astragalus is 15-30 °C. In this temperature range, more feed should be added. The feed amount of general dry material can be 3% to 5% of the total weight of Astragalus in the tank. Fresh bait feeding can be 5% to 10% of the total weight of the jaundice in the tank. When the temperature is lowered by 15°C or less, or when the temperature is increased by more than 30°C, less feed is to be put in, and feeding is to be performed at the same time according to “four settings†(timing, positioning, The principle of qualitative, quantitative) feeding.
3, the daily management of Astragalus breeding should be scientific feeding, to prevent deterioration of water quality, often keep the water fresh, change the water every 2 days 1, the deep season can deepen the water. When the weather is hot, prevent oxygen deficiency in the water, take water injection and increase oxygen or other oxygenation measures to ensure the dissolved oxygen in the water. When it rains, check whether the overflow is unblocked, whether the fences are firm, and drain in time to avoid running away with the rising water. At the same time should also pay attention to heatstroke, antifreeze, anti-temperature difference is too large, often adhere to the tour pool. Once problems are found, they must be dealt with promptly.
4. Diseases and diseases of Astragalus: Astragalus membranaceus has strong disease resistance and few diseases. However, it is easy to be traumatized and susceptible to hydromycosis in early feeding. Therefore, 5% iodine is used to apply wounds or 4% saline is used to dip the jaundice before delivery. 3-4 minutes. The principle of prevention is mainly adopted, and emphasis is placed on prevention and prevention. The water body is disinfected once a week. The medicine used is compounded sodium chlorite at a dose of 0.3 g/m3 or 5 to 10 g/m2 of lime for each square meter. Pulp Quanchiposa.
