1. Choose a good breed. Choose small radish varieties that are not easy to chaff and have fine flesh.
Second, sowing in an appropriate time. Sowing in the right time, don't rush early. The folk saying is "toufu radish and two fucai". In recent years, many people have blindly changed to "fuqian radishes and fucai", and advance the sowing date by more than one week. This is also the main reason why there are many radish hearts everywhere.
3. Reasonable dense planting. Large varieties generally have a row spacing of 50-60 cm and plant spacing of 20-30 cm; medium-sized varieties have a row spacing of 40-50 cm and plant spacing of 15-20 cm; small varieties have a row spacing of 8-10 cm.
Fourth, balanced fertilization. Fertilization should be based on the principle of base fertilizer as the mainstay and topdressing as the supplement, pay attention to the reasonable combination of nitrogen, phosphorus and potassium, and apply fertilizer scientifically. For varieties with sufficient base fertilizer and short growth period, less topdressing can be used; for large varieties, the growth period is long, and topdressing can be less frequent. Topdressing is in the seedling stage, leaf growth stage and fleshy root expansion stage. Use 10-15 kg of urea per mu. 3~5kg of superphosphate and 15~20kg of potassium sulfate are sufficient.
5. Watering scientifically. Control the humidity of the soil to prevent over-drying and over-wetting. Use the method of "drought thoroughly and water evenly in cloudy days" to keep the soil moisture at 70%~80%. If the water demand is large in the middle and late stages of growth, water supply is sufficient, but the amount of watering should not be too much to prevent overgrown above ground. The folk practice is: "Don't dry the ground without watering it, water it immediately when it turns white".
Six or three sprays to prevent chaff. 1. Spray boron fertilizer: Boron fertilizer can promote the radish heart to grow bigger. From the start of the radish seedlings growing 2~3 true leaves to about half a month before harvest, spray boron fertilizer once every 20 days, use 150 grams of borax or 100 grams of boric acid per mu each time, first dissolve it with a small amount of warm water. Spray 60~75 kg of water evenly, and the spray time is appropriate in the evening. 2. Spray paclobutrazol: paclobutrazol has the function of controlling the excessive growth of plants and reasonably regulating the distribution and operation of photosynthetic products in plants. During the growth period of radish plants, use 15 grams of 15% paclobutrazol wettable powder per mu, and spray 50 kilograms of water evenly. Generally, the medicine can be used once for non-overgrown fields. 3. Spraying naphthalene acetic acid: spray 10 mg/kg naphthalene acetic acid solution twice at an interval of 10 to 15 days in the late growth period, which will not affect the growth of fleshy roots, but also prevent the bran core and delay maturity. When spraying 10 mg/kg naphthalene acetic acid, add 5% sucrose and 5 mg/kg borax liquid, and spray the three together, the effect of preventing and controlling bran heart is better.
Seven, timely harvest. For spring and summer radish varieties, choose to sow at the right time and harvest at the right time to prevent the chaff due to late harvesting and loss of water.
8. Scientific winter storage. During winter storage, ensure that the cellar temperature is around 1℃~2℃, the temperature and humidity are moderate, not too high or too low, to ensure that the radish will not lose water or rot, and can survive the winter normally without being damaged by freezing. If the above points are achieved, the phenomenon of radish chaff will be effectively prevented.

Carnitine, or trans. carnitine, is an amino acid, a quaternary ammonium cationic complex, which can be biosynthesized from both lysine and methionine and is involved in the metabolism of fat into energy in the body. Carnitine has two stereoisomerism: L-Carnitine, which is biologically active, and D-carnitine, which is non-biologically active. L-carnitine (L-carnitine) is an amino acid widely distributed in the liver, especially in myocardium and skeletal muscle. Most of the carnitine required by the body comes from meat and dairy products in the diet. [1]
Carnitine is an amino acid widely distributed in the liver, especially in cardiac muscle and skeletal muscle. Most of the carnitine components required by the body come from meat and dairy products in the diet. In addition, the body itself can synthesize part of methionine as raw material, and the body needs Vitamin C, iron, B6 and niacin as auxiliary factors of various enzymes in the reaction when biosynthesizing carnitine. L-carnitine is widely present in the body, especially in mitochondria. The concentration of L-carnitine was highest in the adrenal gland, followed by the heart, bone, muscle, adipose tissue and liver. Free L-carnitine is excreted in the urine. Plant-based foods contain less l-carnitine (in some cases none), as well as less lysine and methionine, the two essential amino acids that make carnitine. The l-carnitine content in animal food is high, especially in liver. Foods rich in L-carnitine include yeast, milk, liver, meat and other animal foods. Humans and most animals can also meet their physiological needs through synthesis within their bodies. L-carnitine is not deficient under normal conditions.
