Cabbage heart planting technology and management method is as follows:

1, sowing time

Early maturing varieties in the summer or summer and autumn, medium maturing varieties in the fall, late maturing varieties in the fall and winter season direct sowing or seedling.

2, seedling

Cabbage hearts in the fall and winter sowing, 400-500 grams of seed per mu. When sowing in the spring and summer seasons, 500-700 grams of seed per acre. The use of live broadcast, early and medium-maturity varieties of row spacing 16 cm, 13 cm spacing, late varieties of row spacing 20 cm, 18 cm spacing. When the seedling true leaves unfolded in time for an inter-seedling, with the growth of seedlings and then inter-seedling, seedling period is generally 20-30 days.

3, reasonable fertilization and irrigation

The seedling period should be based on basal fertilizer, appropriate fertilizer, generally 1000 kg of farmyard manure per mu, when the first true leaves unfolded when the first fertilizer, combined with watering, and then after a week of fertilizer, to promote the differentiation of flower buds. Keep the soil moist during the seedling period, watering can not be too much.

4, timely transplantation

When the seedlings grow to 4 true leaves will be transplanted planting, early varieties of row spacing 16 cm, plant spacing 13 cm. Late-maturing varieties of row spacing 20 meters, plant spacing 16 cm.

5, field management

Cabbage heart grows rapidly, fertilizer management must be timely, in addition to more than 2,000 kilograms of farmyard manure per acre as a base fertilizer, to be used in the fast-acting complete fertilizers such as human and animal feces and urine for fertilizer.

Fertilizer period and the amount of fertilizer, seedlings planted 2-3 days after the new roots when the concentration of 20% of the rotted feces and urine. The concentration of 30-40% of feces and urine is applied when the buds appear. After the main shoots are harvested, the concentration of 40-50% of feces and urine is applied. Each time the application of 2000-4000 kilograms per mu, can also be combined with the application of urea 10-20 kilograms. Watering to often keep the soil moist can be.

6, harvest

Cabbage shoots grow to the first flower harvest, early varieties of more than one-time harvest, late varieties in the harvest of the main shoots to stay at the base of the 2-3 leaves cut diagonally, in order to facilitate the side of the shoots sprouting.
