Detailed Explanation of the Key Technical Points for Growing Organic Chinese Cabbage
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 cabbage is green and healthy. Therefore, it differs somewhat from ordinary cabbage growing methods, so how should organic Chinese cabbage be grown? Below, the editor brings you the growing 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 growing base with a beautiful ecological environment. The growing base must be far from factories, major traffic routes and other heavily polluted places. Ensure that air quality, water sources and so on all meet organic growing standards. In addition, the previous crop in the soil must not be a cruciferous crop such as cabbage. After choosing the site, do the land preparation work well, plow it level and form ridges, make high beds, 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 according to the environmental conditions and soil conditions of the growing area, ensuring the varieties have high yield, strong growth capacity, good quality and strong disease resistance. Then sow generally around July each year, mainly by drilling and hole sowing. When drilling, dig the sowing furrows well and water before sowing; after the water seeps into the soil, evenly scatter the seeds into the sowing furrows. For hole sowing, control the sowing density well and dig the sowing holes; sow about 5 seeds per sowing hole, then 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 fertilizer needs to be applied during the period before emergence. 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, begin thinning; after thinning, water appropriately 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 the hoeing and weeding work well to prevent weeds from competing for nutrients, and topdress appropriately. When the seedlings have grown for about 3 weeks and produced 5 true leaves, they can be transplanted.
4. Field Management
Water thoroughly the day before transplanting to make it easier to lift the seedlings for transplanting and prevent damage to the cabbage roots that would affect growth. After transplanting, control the hoeing depth well according to the soil and planting position, then earth up appropriately to cover the cabbage roots and prevent the roots from being washed bare by water. When the cabbage grows to the rosette stage and the seedlings are thinned to a stand, topdress with an appropriate amount of biological organic compound fertilizer and water appropriately to promote fertilizer decomposition. During the heading stage, control the water amount to prevent excessive water from causing the leaf stalks to crack and causing root rot.
The above is a brief introduction to organic Chinese cabbage growing 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 and so on to prevent affecting the quality of organic Chinese cabbage. That is all for today's introduction.
