Cabbage planting techniques include variety selection, plot selection, sowing method, water and fertilizer management, and the planting time is generally from mid-August to late June of 10.
1, variety selection
Carex rotundifolia and Camellia oleifera have late bolting time and high shoot yield, which are suitable for sowing in autumn and picking shoots in the next year. Because of the slow growth of seedlings, it is not suitable for green leaf cultivation and softening cultivation. Yellow moss grows fast and is easy to pick in early spring. Generally, harvesting leaves in spring, or harvesting leaves or seedlings in greenhouse in autumn and winter are also used as softening cultivation.
2. Land selection
Chinese cabbage has low requirements on soil, but in order to obtain high yield and high quality, it is necessary to choose loam or sandy loam with deep soil layer, high soil fertility and good irrigation conditions to cultivate Chinese cabbage. Before sowing, more than 2,000 kilograms of decomposed farmyard manure and 20-30 kilograms of ternary compound fertilizer were applied, and then more than 25 centimeters were ploughed, and the soil was refined before sowing.
3. Sowing method
Before sowing, water to make water, and sow with water. Because the seeds are very small, they need to be mixed with fine soil or sandy soil for sowing or drilling, with a row spacing of about 20 cm and a ditch width of 3 cm. Seeds need to be 0.2-0.3 kg per mu, and the covering soil is 1 cm thick, and seedlings can emerge in about 10 days. If the soil is dry, you need to water it to keep it moist.
4. Water and fertilizer management
After the true leaves appeared, the seedlings began to be thinned several times, and the spacing between seedlings was kept at 6- 10 cm. After thinning, protect roots with water. After the seedlings are fixed, topdressing can be started. We can spray root Shang Ya once to promote rooting, germination, good growth and strong roots, accelerate root recovery, enhance the ability of crops to absorb mineral elements and water, quickly grow new roots, and greatly improve nutrient absorption.
Planting time
In general, winter moss is sown in autumn from mid-August to late June 10. The specific criteria are: grow to more than 10 leaves before stopping growth in winter, and the plant height reaches 0.5-0.7 meters. Leaves are harvested before winter, and fleshy roots are brought in winter.
