The Latest Technical Methods and Tutorial for Organic Chinese Cabbage Cultivation
Organic Chinese cabbage, as the name suggests, is grown using organic agricultural methods, and during the growing process it must be cultivated according to the production technical standards for organic food. No pesticides, chemical fertilizers or other substances harmful to cabbage are used, ensuring the green and healthy quality of the Chinese cabbage. Therefore, there are some differences from ordinary cabbage cultivation methods. So how should organic Chinese cabbage be grown? Below, the editor brings you the cultivation techniques for organic Chinese cabbage. Let's take a look!
1. Site selection and land preparation
The first and most important step in growing organic Chinese cabbage is to choose a pollution-free planting base with a beautiful ecological environment. The planting base should be far from factories, major traffic roads and other heavily polluted places. Ensure that air quality, water sources, etc. all meet the standards for organic cultivation. In addition, the previous crop in the soil must not be cabbage or other cruciferous crops. After selecting the site, do a good job of land preparation, plow it level and form ridges, make high beds, and deep plow about 30 cm, then apply sufficient decomposed farmyard manure together with an appropriate amount of organic biological fertilizer.
2. Seed selection and sowing
Choose good varieties for planting according to the environmental conditions and soil conditions of the growing region, ensuring the varieties have high yield, strong growth capacity, good quality and strong disease resistance. Then sowing is generally done around July each year, mainly by drilling and dibbling. When drilling, dig the sowing furrows well, water before sowing, and after the water seeps into the soil, evenly scatter the seeds into the sowing furrows. For dibbling, control the sowing density well and dig the sowing holes, sow about 5 seeds per hole, cover with fine soil after sowing, and water to promote seed germination.
3. Seedling management
After sowing, pay attention to observing soil moisture and weather changes. If the soil moisture is sufficient and it rains, then no fertilization is needed during the period before seedlings emerge. However, be careful to keep the soil moist. If the moisture is poor, then after sowing you need to water thoroughly. About one week after the seedlings emerge, start thinning, water appropriately after thinning, and spray foliar fertilizer. Then carry out a second thinning when there are 4 true leaves, following the principle of keeping the strong and removing the weak. Then do a good job of intertillage and weeding to prevent weeds from competing for nutrients, and apply appropriate topdressing. When the seedlings have grown for about 3 weeks and have 5 true leaves, they can be transplanted.
4. Field management
Water thoroughly the day before planting to make it easier to lift the seedlings for transplanting and prevent damage to the cabbage roots that would affect growth. After planting, control the depth of intertillage according to the soil and planting position, then appropriately earth up to cover the cabbage roots and prevent the roots from being washed bare by water. When the cabbage grows to the rosette stage and is being thinned to a stand, apply an appropriate amount of bio-organic compound fertilizer and water appropriately to promote fertilizer decomposition. During the heading stage, control the amount of water to prevent excessive moisture from causing the leaf stalks to split and causing root rot.
The above is a brief introduction to organic Chinese cabbage cultivation techniques. When growing organic Chinese cabbage and carrying out pest and disease control, pay attention to the use of agents. Pesticides must not be used; mainly use oxytetracycline, agricultural streptomycin, etc., to prevent affecting the quality of organic Chinese cabbage. That is all for today's introduction.
