Cabbage, as a vegetable variety with a larger cultivation area in the Jianghan Plain in autumn, has formed a relatively mature industrial chain in Hubei. Yafei Xinwangwang, as the largest cabbage variety with the largest planting area, is mainly due to its following major advantages :

① Sell well and sell high: The vegetable dealers give priority to buying Yafei Xinwangwang, and they are willing to bid higher than other varieties. It has formed the habit of buying Yafei Xinwangwang by name.

②Good management in the field: thick leaves, better disease resistance and stress resistance.

③Good low-temperature resistance: good low-temperature balling property, long in the garden.

④The yield is high and stable: about 4000 plants/mu, 1.25-1.5kg per ball.

⑤ Kind Yafei Xinwangwang has free insurance: farmers can plant them more assuredly and at ease.

1. Introduction of Yafei Xinwangwang Products

It matures earlier and can be harvested within 58-63 days after planting. It is suitable for cultivation in spring and autumn, especially in autumn. The leaf ball is spherical, and the weight of a single ball is about 1.25-1.50kg.

The leaves are thick, the luster is good, the color is bright green, the root system is developed, the low temperature resistance is good, the disease resistance is good, the garden is longer during the low temperature period, and the commercial property is excellent.

Second, the method of raising seedlings
The seeds of Yafei Xinwangwang are full of seeds, and the germination rate and germination potential are very high. It is recommended to use single-seed seeding to raise seedlings.
The time for raising seedlings is recommended from August 15th to August 25th (in Hubei area).

Choose disease-free loam or seedling substrate mixed with a small amount of organic fertilizer or finished seedling substrate as seedling soil. The substrate soil should be disinfected. Carbendazim can be added for disinfection. Generally 400g carbendazim can be 2000 Disinfect the substrate. The mixed matrix should be held into a ball by hand, and it will disperse when it is pinched by hand. The loading of the plate should be loose and full, not only filling each hole, but also keeping each hole loose.
Then sown 1 seed per hole, then cover with a layer (1-2cm) of thin soil and water enough. Seedling trays need to be placed flat, otherwise uneven watering and uneven emergence. Keep the soil substrate moist during the emergence period.

The principle of seedbed watering: generally water in the morning and replenish water in the afternoon, so that it can be thoroughly watered but no water can accumulate.  

In August, the seedlings are cultivated with upright high temperature. The shade is used to cool down. Generally, use sunshade nets to cool down from 10 am to 4 pm. Once the seedlings have grown and stabilized, try to let them receive more sunlight to avoid excessive growth. In addition, the sprinkler that draws water must use a sprinkler with fine and soft water to avoid high impulse and damage to the seedlings.  

The principle of seedbed fertilization: After the seedlings are broken, you can apply 0.2% water-soluble fertilizer (balanced fertilizer + micro-fertilizer) every 7 days.

3. Management of seedbed diseases and insect pests
The main preventive diseases and insect pests of seedbed: damping-off, damping off, downy mildew, jumping beetle, diamondback moth, beet armyworm.
Medicine period: Start medication when the cotyledon just unfolds, mainly to prevent the hazard of jumping beetle and damping-off; after that, the hazard of diamondback moth and beet leaf moth should be prevented; pay attention to observation at ordinary times, and sometimes ground maggots will appear at the base of the root. For the hazard, you can add some deltamethrin when watering.
Medicine plan: Early use of hymexazol + jumping note (to prevent falling and jumping nails); add chlorothalonil/toxin alum and ivy (spinetoram)/emamectin benzoate in the middle and late stages (Prevents Plutella xylostella, downy mildew, etc.).
Principle of spraying medicine: Prevention is the first priority, and medicine is given once every 7 days.

Four. Field management
The seedling period should be controlled at 25-30 days. The temperature in autumn is high and the growth is fast. The seedling age should not be too long. Long. Transplant in time when the seedlings grow 4 to 5 true leaves. Before planting, prepare the soil and blanch the soil. Apply 1000-2000kg of decomposed organic fertilizer and 30-50kg of ternary compound fertilizer per 667m2 as base fertilizer, and apply 2～3kg of boron fertilizer and 20-30kg of potassium and magnesium sulfate when planting. The width of the border is 1.0-1.2m, and the planting is double-row, and the plant spacing is 30-40cm. Generally, there are 4000-4500 plants per 667m2.

Foliar sprays can be made with "agricultural streptomycin" and "mancozeb" during the rosette and capping stages to prevent the occurrence of diseases. Pay attention to applying plantar fertilizer, less nitrogen fertilizer, and more phosphorus and potassium fertilizer. At the same time, pay attention to the use of effective boron fertilizer and zinc fertilizer to enhance resistance and increase yield. Stop watering before harvest and harvest at the right time to avoid cracking the ball.

Fertilizer and water management: Cabbage has a long growth period. Fertilizers should be applied diligently and thinly in the early stage of growth, and more fertilizers should be applied during the rosette period, with nitrogen fertilizer as the mainstay. 7 days after planting, 1% compound fertilizer or urea water can be used for topdressing once, and then topdressing once every 7-10 days (appropriate thin application). The amount of fertilizer applied during the rosette period should account for 50% of the total fertilizer amount, and increase appropriately Phosphorus and potassium fertilizer dosage: apply 30-50kg high-quality ternary compound fertilizer per 667m2, topdressing once every 7-10 days, and gradually increase the amount of topdressing. After topdressing, water thoroughly in time to facilitate the plants to absorb fertilizer and maintain the soil throughout the period Moist.

Pest control: The main pests of cabbage include beet armyworm, diamondback moth, cabbage borer, and cabbage caterpillar. Chlorantraniliprole is used to control insect pests with good results.

The main diseases are damping-off, blight, black rot, black root disease and virus disease. Applying before planting can greatly improve the effect of medication. Generally, you can use hymexazol and root water to irrigate first, apply 1 to 2 times more if possible, and then use the medication in order according to each disease.

5. Timely harvesting
Mastering the product harvesting time is the key to ensuring high yield, stable yield and good commercial properties of cabbage. If the harvesting time is too early, the output is not high and unstable; if the harvesting is too late, the phenomenon of cracking balls is prone to occur, which seriously affects the quality and output.
The growth cycle of Asian-African Xinwangwang cabbage is about 60 days, and low temperature may delay the harvest period. The temperature gradually decreases in the later period, and Yafei Xinwangwang has good low temperature tolerance and strong disease resistance, which can ensure the yield and quality of vegetables. This is why it has been loved by growers for many years.
