What season is red cabbage moss suitable for planting?
Cabbage is one of Brassica in Cruciferae, biennial plants. It is mainly distributed in the Yangtze River valley, and now it is cultivated in all parts of China.
According to historical records, red cabbage moss was a famous vegetable in the Tang Dynasty. It has always been a local product of Hubei province that pays tribute to the emperor. It was once named "Golden Temple Jade Cuisine", which is as famous as Wuchang Fish.
Cabbage moss is usually planted in August 8- 10/0, and there are planting methods such as sowing and seedling raising. However, the sowing time can only be determined according to the variety characteristics and local climatic conditions.
Usually, the early-maturing varieties in the Yangtze River basin are generally sown in August-September; The late-maturing variety 9-10 was sowed in October to raise seedlings; The sowing date of medium-mature varieties is between the two.
Planting techniques of October red cabbage moss
Sowing and seedling raising
Seedbed should be built in a shady place with convenient water source and good drainage, and the bed soil should be fertile and loose, with water and fertilizer conservation.
Apply decomposed high-quality farmyard manure 1000 kg per mu of seedbed, then turn over the soil and rake it to make it smooth. It is required to sow thinly and evenly, and the sowing amount per square meter of seedbed is 1 00g, and the seedlings cultivated per square meter can be transplanted to1mu of land.
After the seedlings are fully planted, the seedlings are thinned for 2-3 times, and the distance between the seedlings for the third time is about 3 cm. Generally, attention should be paid to fertilization and watering to prevent and control pests and diseases. When the seedling growth is not good, it can be topdressing with available nitrogen fertilizer, and the seedling can be transplanted when there are 5 true leaves.
field planting
Red cabbage moss is not suitable for continuous cropping with cruciferous vegetables. Before planting, dig deep into the soil, and apply decomposed farmyard manure 1500~2000 kg and 30 kg of calcium superphosphate as base fertilizer per mu.
The row spacing of seedlings transplanted is 60-65cm, and the spacing between plants is 25-30cm. When planting, choose sunny afternoon, and the effect is better. When transplanting, water is poured at the same time, and1-2 plants are planted in each nest.
field management
The growth period of red cabbage moss is long, and it is harvested one after another, so it is required to pay equal attention to base fertilizer and topdressing. After the survival of colonization, sufficient fertilizer water was applied during the vigorous growth of leaves and the formation of cauliflower, and 2000 kilograms of manure water was applied per mu. In addition, the fertilizer and water should be controlled in winter to avoid excessive growth and freezing injury.
Pest control
Viral diseases are easy to occur in high temperature and drought, and soft rot is easy to infect when the soil is too wet. In the prevention and control, crop rotation is the main way to realize flood and drought or grain and vegetable rotation. In low-lying areas, deep furrows and high ridges should be made, and diseased branches should be thoroughly removed and buried in the soil.
In addition, we should pay attention to timely sowing, cultivate strong seedlings, supplemented by drug control. If there are Plutella xylostella, Spodoptera litura and aphid pests, control them in time. It is suggested that biological control should be adopted in harvesting period to reduce pesticide residues.
