So how is red cabbage moss cultivated? Is there any good way to breed? What should I pay attention to when breeding red cabbage moss? Please read with me with questions!
Planting method of sowing time of red cabbage moss:
Sowing is usually carried out from July to late September, and the best sowing time is around summer in late August. Early sowing date, difficult seedling raising, many dead plants after planting, low yield, spicy moss or bitter taste; Delaying sowing date leads to less dead seedlings, but if it is too late, the harvest period will be shortened, the harvest times will be reduced and the yield will be affected. .
Seedling management:
Deeply turn the seedbed flat, and sow 1-2g per square meter of seedbed. To control seedling diseases, 50g of 75 {BF} chlorothalonil wettable powder can be mixed with 50kg of fine soil, with 1/3 as the base and 2/3 of medicinal soil as the seed coating. Keep the soil moist before emergence. In case of high temperature and dry weather after emergence, water it every evening, and pay attention to prevent aphids, yellow striped beetle and diamondback moth. The seedling age of very early-maturing varieties is 20-24 days. After 24 days, bolting may occur in seedbed or before rosette leaves grow after planting. The seedling age of medium-mature varieties is 25 days, and no full-moon seedlings are planted. Only late-maturing varieties can plant full-moon seedlings.
Fine soil preparation and sufficient base fertilizer;
The plot for planting red cabbage moss should be completed 10 days before planting at the latest, so as to bask in the sun. Usually plow and rake twice, and plow and rake again in a few days. Generally, furrow irrigation should be adopted, that is, the furrow should be in 1- 1.2 m (inclusive), with one furrow and two rows, and the furrow of early-maturing varieties can be narrower. Apply plantar fertilizer before planting, and apply 2500 kg of high-quality farmyard manure or compound fertilizer 100 kg every 667㎡.
Colonization:
Water the seedbed the day before sowing to get the seedlings. When planting, it is best to take seedlings with soil. If you can't take them, try to damage the roots as little as possible. Don't plant the seedlings too deep to avoid covering them. Water them while planting. It is best to irrigate one field at a time after sowing, but only by immersion irrigation, not by flooding irrigation. Very early-maturing varieties have a narrow row of 35-40 cm, and early and middle-maturing varieties have a narrow row of 40 cm, with a spacing of 30-35 cm. If there is early moss before and after planting, the main moss can be removed, nitrogen fertilizer can be applied appropriately, and urea 15kg/667㎡ can be applied in conjunction with irrigation to raise seedlings.
Fertilizer and water management:
Keep the soil moist throughout the growth period, and water it in time when the leaves wilt. Topdressing 4-5 times in the whole growth period, topdressing urea 5- 10kg in 667㎡, topdressing for the second time before enclosure, topdressing potassium chloride+urea 10kg in 667㎡, topdressing lateral moss and sun-dried moss once, and harvesting.
Note: Carbamide is not recommended for vegetables. Fertilizer and water are closely related to the formation of Chinese flowering cabbage. Sufficient fertilizer and water are needed before and after germination to ensure the formation of well-nourished flower stems, especially early-maturing varieties. Nitrogen is the most absorbed mineral nutrient, followed by potassium and phosphorus. The ratio of nitrogen, phosphorus and potassium is 5:3: 1. Flowering stems are long-day plants, but most varieties are not strict about the length of light. The flower bud differentiation and stem growth rate are mainly affected by temperature, and the top flower grows for 50-58 days.
Pest control:
The main diseases are downy mildew, soft rot, virus disease, black spot disease, clubroot and so on. And we should pay attention to the influence of soil and crop rotation on clubroot. Pests mainly include flea beetle, aphid, cabbage caterpillar and diamondback moth. Attention should be paid to observation and timely prevention and control of pests and diseases.
Downy mildew: It mainly occurs in the growing period of rosette leaves, and it is sprayed with 500 times of 25 {BF} metalaxyl or 600 times of 58 {BF} carbendazim from Jin Lei.
Soft rot: It mostly comes from infected parts of harvested plant wounds, and it is generally serious in high temperature period. As the temperature drops, the illness is alleviated. After picking the moss, smear the wound with mud to prevent infection. After harvest, 200mg/L agricultural streptomycin or 50 {BF} DT 300 times solution or 77 {BF} kocide 500 times solution or 15 {BF} mancozeb 600 times solution or 75 {BF} chlorothalonil wettable powder 800- 1000 times solution can also be sprayed.
Viral diseases: Spray 25 {BF} virus A250 times solution or 83 anti-infective agent 300 times solution for prevention and treatment, and cooperate with foliar fertilizer to preserve potassium or potassium dihydrogen phosphate solution.
Harvest:
When the cauliflower grows to 35-40cm, 2-3 flowers bloom and a few buds become Huang Shi, it can be harvested. Generally, harvesting begins in the first ten days of 10/0/0, twice a week in the early days, and once a week in the late days when the temperature is low. Harvesting should be carried out in the afternoon to reduce mechanical damage.
Efficacy Red cabbage moss has high nutritional value and contains many nutrients. Many vitamins are higher than Chinese cabbage and Chinese cabbage. It can tonify liver and improve eyesight, and treat night blindness. Red cabbage moss can not only help the human body improve its resistance, but also maintain the normal metabolism and function of human tissues and cell structures. Especially pregnant women, should eat more red cabbage moss, red cabbage moss can enhance maternal resistance and promote fetal growth and development.
Generally speaking, red cabbage moss is not difficult to grow, so pay attention to the control of fertilizer and water when planting. Here is to introduce the planting method of red cabbage moss. I hope everyone can plant red cabbage moss well.
