How to grow bok choy.
Growing cabbage during the dog season is an important agricultural activity, and the climatic conditions at this time are very favorable for the growth of cabbage. If you want to grow bok choy well, you need to pay attention to the following aspects:
First of all, choose the right variety. According to the local climate, soil and market demand, choose a cabbage variety that is suitable for planting in the dog season. Generally speaking, varieties that are early-maturing, heat-tolerant, and disease-resistant are more suitable for planting during the dog season.
Second, choose the right land. Land where cabbage is grown needs to be well-drained, rich in organic matter, fertile soil, and well aerated. At the same time, it is necessary to avoid continuous cropping with cruciferous vegetables to avoid the spread of pests and diseases. Before planting, it is necessary to plough the land and apply sufficient base fertilizer to facilitate the growth of cabbage.
Third, sow seeds at the right time. The climate during the dog season is hot, so it is necessary to determine the appropriate planting time according to the local climatic conditions and variety characteristics. Generally speaking, the sowing time of bifu cabbage is between mid-July and early August, and the specific time can be adjusted appropriately according to the actual situation. Before sowing, the seeds need to be treated, such as drying seeds, germination, etc., to improve the germination rate and growth rate of the seeds.
Fourth, reasonable dense planting. Reasonable dense planting is one of the key measures to ensure the high yield of cabbage. Generally speaking, the planting density of early-maturing varieties is 3000-4000 plants per mu, and the planting density of medium-late maturing varieties is 2500-3500 plants per mu. When planting, it is necessary to master the row spacing and plant spacing to ensure the growth space and ventilation and light transmission of cabbage.
Fifth, scientific fertilization. Fertilization is one of the important measures to ensure the high yield and quality of cabbage. Before planting, it is necessary to apply sufficient basal fertilizer, mainly organic fertilizer, with an appropriate amount of chemical fertilizer. During the growth period, top dressing is also required, and the type and amount of top dressing should be determined according to soil fertility and the growth of cabbage. At the same time, it is necessary to pay attention to controlling the amount of nitrogen fertilizer, so as not to cause excessive growth of cabbage and the increase of pests and diseases.
Sixth, strengthen water management. Growing cabbage in the dog season requires attention to the water content and management. Since the temperature is high, the water evaporates quickly, so regular watering is required to keep the soil moist. At the same time, it is necessary to pay attention to avoid the breeding of diseases and the occurrence of root rot caused by excessive water. In the rainy season, it is also necessary to strengthen drainage work to prevent the occurrence of waterlogging.
Seventh, pest control. The growth of cabbage in the dog season is susceptible to the attack of pests and diseases, so pest control is an important task in the planting process. It is necessary to conduct regular field inspections to detect and prevent the occurrence of pests and diseases in a timely manner. In the process of prevention and control, it is necessary to give priority to the use of biological control and physical control measures, and reduce the amount and frequency of use of chemical pesticides to ensure the safety and quality of vegetables.
Finally, harvest at the right time. Timely harvesting is the last link to ensure the quality and yield of cabbage. In general, early-maturing varieties of cabbage can be harvested 45-60 days after planting, while mid-late varieties need to wait 60-80 days for harvesting. Before harvesting, a field inspection is carried out to determine the growth and ripeness of the cabbage, and then the harvest is carried out. Handle with care during harvest to avoid mechanical damage and sunburn. After harvesting, it should be processed and sold in time to ensure the freshness and quality of vegetables.
In short, in order to grow cabbage well and obtain high-yield and high-quality products, it is necessary to pay attention to variety selection, land selection, timely sowing, reasonable dense planting, scientific fertilization, water management and pest control. At the same time, it is also necessary to make appropriate adjustments and improve management measures according to the actual situation, so as to improve the yield and quality of cabbage and increase the economic and social benefits of farmers.
