In recent years, with the rise of the hot pot city, the demand for Chinese kale cabbage has continuously increased, and the price of Chinese cabbage cabbage is also relatively good, and the benefits are considerable, causing many farmers to cultivate interest, but there are not many harvests.
Since Korean cabbage was introduced into northeast China, it solved the problem that cabbage could not be served in spring. Korean cabbage was popular with people because of its tender texture, good taste, tight ball and high yield. However, Korean cabbage is easy to convulsive in early spring, and the damage caused by pests and diseases is very serious. How can the Chinese cabbage be produced prematurely with high yield? The author introduced a set of successful experiences of high yields of preterm birth obtained through years of practice to farmers' friends.
1. Selection of Fine Varieties In the past, some people had made domestically produced varieties, such as the Lubai series, cultivated in early spring. The results all failed. Some Korean varieties are suitable for early spring cultivation. However, due to the fact that there are dozens of varieties in South Korea and there are also large differences in the performance of various varieties suitable for early spring cultivation, it is difficult for farmers to select seeds. In the autumn, five rounds cannot be cultivated in the early spring. Although the spring and summer kings can barely cultivate, they are easy to twitch. So, which varieties are suitable for early spring cultivation? Practice has proved that Yangchun, Qiangjing, Jujin, Spring and Autumn and other varieties have good anti-convulsions, good spherical shape and high yield, and are most suitable for early spring cultivation.
2, to prevent vernalization convulsions to avoid premature sowing, cultivation in the greenhouse should be in mid-February, the greenhouse nursery, film and arch membrane cultivation should be in early March, greenhouse nursery, open field film cultivation should be late April to 5 At the beginning of the month.
Seedlings should be kept warm during seedling age. Vernalization may be completed if the seedlings are kept below 5°C for 4 days. If the seedlings are kept below 15°C for about 20 days, vernalization may occur, and the seedlings may not be cultivated at low temperatures. With timely colonization, the seedling leaves of Chinese cabbage should not exceed 6 pieces, and when more than 6 leaves are planted, vernalization may also occur.
3, sowing cultivation techniques sowing, select a good variety after soaking with warm water, and then with a good breathable breathable cloth, placed at 20 - 28 °C place pregermination. When preparing nutritious soil, mix black soil, excreta, decomposed horse manure, and a small amount of sieved ash, and apply it to a 4 to 5 cm thick layer of mud. Use a fork to draw a 4 cm long and 4 cm wide earth, and then The seeds of freshly emerged buds were sown on each earth, and they could not be rebroadcast and leaked. After sowing, they were covered with a fine layer of fine soil.
Cultivation, until the cabbage seedlings grow to 5-6 leaves, the cabbage seedlings planted on both sides of the ridge on the ridge, the spacing of 35-45 cm, when planted after the film, the diaphragm on both sides of the diaphragm every 70- 80 cm buried a heap of soil, then immediately irrigation, irrigation and then use the plow to bury the mulch on both sides. At the beginning of May, when the temperature reached above 20°C, when the Chinese cabbage seedlings completely bulged the mulch, a small hole was drilled against the cabbage seedlings to prevent roasted seedlings. In the next week or so, all the seedlings will be drawn out and immediately filled with water. After a few more days, they will be marketed. The output per mu can reach more than 10,000 kilograms.
4. Disease Prevention The ball-bearing period of Chinese cabbage in early spring is the high temperature and rainy season in Northeast China, which is the peak period of soft rot and black rot. Soft rot and black rot are also diseases that are vulnerable to cabbage. First, early disease prevention, early disease-free prevention, use seedlings in the nursery, or "Feng Ling" and other seed dressing agents, the use of "enexone" water injection points when planting. Then use “Fengling†or “Chinese Cabbage Anti-corrosion Agent†to spray once in the rosette period, growth period and the filling period of Chinese cabbage to prevent or reduce the infection of disease cabbage on Chinese cabbage and make Chinese cabbage more productive.
5. Pest Control The method for controlling Plutella xylostella is the most direct and effective method for biological control and drug control. Biological control can use bacterial insecticides, such as BT emulsion 600 times liquid can make diamondback moth larvae susceptible to death. Chemical control can be used to control 24.5% of efton No. 3 2000 times, high efficiency cypermethrin 1500 times, Avilife 1500 times, 5% of stuck 2,000 times to prevent and control, pay attention to alternate use or mixed use to slow down The emergence of drug resistance.

An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others.
Antifungal pharmaceuticals include Terbinafine HCL, here is the structure:
An antibiotic (from ancient Greek αντιβιοτικά, antibiotiká), also called an antibacterial, is a type of antimicrobial drug used in the treatment and prevention of bacterial infections.
Sometimes the term antibiotic (which means "opposing life") is used to refer to any substance used against microbes.
