First, seed selection and seedling cultivation of small Chinese cabbage.
1, because small vegetables can be planted in almost every season, seeds suitable for the season should be selected when planting. Some varieties of small vegetables have good cold tolerance, such as slow March, which is more suitable for planting at this time.
2. Nursery beds need to be arranged in advance, and a proper amount of fully decomposed farmyard manure should be applied. If it is not completely decomposed, it may adversely affect the growth of small vegetables in the later period and may lead to diseases. After finishing, scatter the seeds on the soil and let them grow freely. According to the situation, the seedlings should be thinned again to prevent uneven growth.
3, the soil should be soft and fertile, so as to ensure that small vegetables can grow better. When selecting, deep ploughing and disinfection should be done in advance, and then colonization should be done according to the growth situation. If this link is not done well, it may lead to poor growth of the roots of Chinese cabbage, leading to root necrosis and affecting the growth and development of Chinese cabbage.
Second, the management of small vegetables.
1, small vegetables don't need much water, as long as the soil can keep moist. Therefore, before sowing, it is necessary to ensure enough soil moisture to facilitate seed germination. After emergence, the amount of water can be determined according to the climate. Generally speaking, high temperature weather can appropriately increase water quantity and promote plant growth. Drainage measures should be taken in rainy season to prevent waterlogging and affect growth.
2. Topdressing should be carried out reasonably. Small cabbage needs more fertilizer, so it is necessary to apply fertilizer appropriately according to the growth of small cabbage, and the growth of small cabbage can be accelerated by applying water and fertilizer at the same time.
3. If it is found that the soil is hardened under the land where the small cabbage grows, the soil condition can be improved by intertillage and loosening the soil, so as to enhance the nutrient absorption of the small cabbage, which is conducive to increasing the yield of the small cabbage.
Harvest time:
Chinese cabbage has a short growth period and can be planted all the year round, so the harvest time is different, so it is necessary to determine the harvest time according to the sowing time. Generally, when planting in February-March, the harvesting period is about 50-60 days after sowing; Plant in April-May, about 30-40 days. June-August is 25-30 days.
