Cabbage seems simple, but it is not simple. Like other farming industries, it needs to go through many steps and also needs certain planting techniques. The Chinese have accumulated a lot of experience in the cultivation of cabbage, and Xiaobian only lists a small part of it here.
Method of growing cabbage
1. Dig a hole: Use a shovel to shovel a few times in the soil to be burrowed. Finally, it must be shovel perpendicular to the ground, about 7cm deep, and shovel the soil in front of the body to make the opening of the hole 2-3cm.
2, seedlings: take the seedlings in the left hand, so that the roots must be down, from the top right of the hole along the shovel, the roots of the seedlings are inserted obliquely into the hole, be careful not to insert too deep.
3, according to the soil: the left hand to help the seedlings, the right hand take out the shovel and push the soil to the roots, the left thumb to press the solid roots of the soil, so that the seedlings are fixed in the hole soil.
4, planting: with reasonable planting density (usually line spacing of about 20cm, plant spacing of about 15cm), continue to plant other cabbage seedlings.
Cabbage planting techniques 1. Cultivation season: Early-maturing varieties are usually sown in August and mid-August, and are also planted early in late July. Medium-ripe varieties can be sown from late August to early September. Late-maturing varieties should be sown in late August.
2, land selection and land preparation: Chinese cabbage is easy to disease, so it is necessary to carry out rotation, especially to promote grain rotation, water and drought rotation. Cultivation on perennial vegetable plots should avoid continuous cropping with cruciferous vegetables. You can choose to cultivate the early beans, early peppers, early cucumbers, early cucumbers and early tomatoes.
The land of Chinese cabbage should be deeply ploughed for 20-15 centimeters for 10-15 days, and then the land is broken and leveled to make a 1.3-1.7 m wide raft, or a 0.8 metre narrow sorghum or sorghum. When doing sputum, it is necessary to deepen the sulcus and the gutter, and the ditch is more than 27 cm, so that the ditch and the ditch can communicate.
3, heavy application of base fertilizer, mainly organic fertilizer: in the middle and late July, after the harvest, the soil is turned deep, when the soil is prepared, 100-150 kg of lime per acre. In the plot where the clubroot disease occurs, an appropriate amount of lime must be applied to the seeding ditch. Re-application of base fertilizer is required, and NPK is well matched. In the first ten days of July, 40 pigs per mu, 40-50 garbage, 75 kilograms of vegetable waste, 40-50 kilograms of calcium magnesium phosphate mixed and 30-40 manure excrement, and wet with appropriate amount of water Stacked and fermented, and covered with a plastic film to make it fully decomposed. Ditching when doing sputum. At the same time, 10-15 kg of 45% compound fertilizer is applied per mu.
4, sowing: Chinese cabbage is generally used for live broadcast, but also for seedling transplanting. The live broadcast is mainly based on the broadcast, supplemented by on-demand. When the time before the squatting is still empty, in order not to affect the cultivation season, seedling transplanting can also be used. Regardless of the method used, the soil must be neat and flat.
Live broadcast of about 200 grams per mu. Seedling transplanters, each planting 1 mu of field, about 5-6 cents of seedbeds, using the method of spreading, using 75-100 grams of seed. After the live broadcast, 40-50 tons of manure and manure are used per acre, and the ground cover is combined.
After that, water each time in the morning and evening, keep the indigenous soil moist, and emerge in 3-4 days. The row spacing of Chinese cabbage should be determined according to the variety. Generally, the early-maturing variety is 33-50×33 cm, 2100-2300 per acre, and the late-maturing variety is 67*50 cm. The number of seedlings per mu is less than 2000, and the best choice for seedling transplanting is cloudy or sunny. In order to improve the survival rate, it is best to transplant the seedlings with soil and plant the root water after planting.
Fertilizer management of cabbage
1. Seedling stage: The roots of Chinese cabbage seedlings are weak and shallow, and the weather should be watered in time to keep the ground moist, so that the seedlings can absorb water and prevent the surface temperature from being too high to burn the root system. At the same time, in order to ensure sufficient nutrients in the seedling stage, 3 to 5 kg of high-nitrogen compound fertilizer per acre is applied.
2, rosette period: Chinese cabbage needs more water during the rosette period, grasp the ground to see dry and wet, and promote and control the growth of rosette leaves. In order to meet the needs of rapid growth and nutrition of Chinese cabbage in the rosette period, generally combined with watering, 10-15 kg of high-nitrogen compound fertilizer per acre is applied.
3, the balling period: Chinese cabbage requires the most water during the balling period, should be watered at the right time. In the later stages of the ball, watering should be controlled to facilitate storage. In order to promote the ball to be large and strong, in the early stage of the ball, the manure can be applied in the shallow ditch in the center of the sputum. Generally, 20-30 kg of high-nitrogen and high-potassium compound fertilizer is applied per acre.
The distribution of Chinese cabbage is widely cultivated in all parts of China. It is mainly produced in North China and south of the Yangtze River. The planting area accounts for 40%-60% of the planting area of ​​autumn, winter and spring vegetables.
Cabbage is a widely distributed vegetable, and there are many types of cabbage. There are some differences in the types that may be planted in different places. Therefore, when we grow cabbage, we need to choose according to the specific variety and the planting area to maximize the planting benefits.

Vitamins are a kind of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. They play an important role in the growth, metabolism, and development of the human body. In the body, this kind of substance can neither be a raw material for body tissue nor a source of energy, but a kind of regulating substance, which plays an important role in material metabolism.
From the point of view of chemical structure, various vitamins are very different or even unrelated. Therefore, vitamins are usually classified according to their physical properties. They can be divided into fat-soluble vitamins (such as vitamin A, D, E, K, etc.) and water-soluble vitamins ( Such as vitamin C, vitamin B1, B2, B6, B12, pantothenic acid, PP, biotin, folic acid, choline, etc.). Water-soluble vitamins are easily soluble in water but not soluble in organic solvents. They are stored in the body after absorption. Excessive amounts are mostly eliminated in the urine; fat-soluble vitamins are easily soluble in organic solvents but not in water. They can be absorbed by the body with fat and stored in the body, and the excretion rate is not high.
From the perspective of obtaining methods, vitamins can be divided into natural products and chemical synthetic products. Because natural vitamins are limited by raw materials and extraction technology, their yields are low, and their prices are high. Therefore, chemical synthesis takes the lead, accounting for about 80% of the total vitamin output. Among the various segments of the vitamin industry, vitamin B, vitamin E, vitamin C and vitamin A have the largest market shares, 33%, 30%, 21% and 13% respectively. Other vitamins have a smaller market share, accounting for only 3%.
