Green stalk cultivation technology

There are many types and varieties of cabbage, and it has wide adaptability. In the rivers and Huaihe regions of China, in addition to simple cover cultivation in winter and early spring, it can be cultivated in many areas; the southern part of China can be produced on an annual basis. In the cultivation, it is generally arranged in three seasons: 1 autumn, winter cabbage: seedling transplanting, harvesting mainly plant. South China is planted in September-December, and harvested in phases to February of the next year; the Jiang and Huai areas are successively planted from early August to mid-October, and harvested before freezing. 2 Spring cabbage: sowing in late autumn, wintering of seedlings, harvesting of spring in early spring; sowing in early spring, harvesting seedlings. In the early spring, sowing seedlings in cold beds or sowing seedlings after spring equinox can also be harvested and grown. 3 Summer Cabbage: It is mainly cultivated and harvested. It can be planted at any time from early May to early August and harvested continuously. Cabbage is often rotated with melons, beans and field crops. Spring cabbage is intercropped with solanaceous fruits, melons, beans, and yam vegetables; summer cabbage is mixed with celery, sage, carrots and other vegetables; autumn and winter cabbage can be intercropped or interplanted with cabbage, broccoli, lettuce, and potatoes. The annual supply can be achieved by planting different varieties.

In addition to live broadcast for the cultivation of rapeseed in early spring and summer, cabbage is usually transplanted. It is advisable to choose loam that retains water and protects fertilizer and has good drainage to nurse the nursery. Before harvesting, it is necessary to plough the sun, clean the garden, apply the base fertilizer, and prepare the sorghum or sorghum after the soil preparation. Seeding should be mastered and properly diluted. After emergence and time, seedlings should be avoided. After the seedlings, topdressing and watering should be carried out, and attention should be paid to weeding and pest control during seedling stage. Usually transplanted 25 to 30 days after sowing. The planting field is fertilized in advance, cultivated and sun-dried, and used as a hoe. The planting density varies depending on the variety, season and cultivation purpose. Most varieties have a row spacing of 20-25 cm square. The planting depth varies depending on the climate and soil quality. It should be planted early in the early autumn to prevent the bad planting. After the cold dew, the vegetables should be deeper and can prevent cold. The soil is loose, and the planting can be slightly deeper; the sticky soil should be shallow.

The roots of Chinese cabbage are shallow and the absorption capacity is weak. The fertilizer should be continuously supplied during the growth period. The repeated application of quick-acting nitrogen fertilizer is an important measure to promote the growth of cabbage and ensure high yield. The principle of rational fertilization: First, timely topdressing after planting, promote seedlings to restore growth; second, with the growth of cabbage, increase the concentration and dosage of topdressing. As for the method, period and dosage of fertilization, it depends on weather, seedlings, soil, etc. Watering is combined with topdressing. Do not lack water for 3 to 5 days after planting, especially in summer and early autumn. After planting, it should be watered every morning for 3 to 4 days. The cultivated cabbage should be applied with organic fertilizer as the base fertilizer. The fertilizer should be properly applied during the growth period, and the foliar top dressing can also be combined with sprinkler irrigation.

Cabbage plants can be harvested at any time. Adult harvesting standards: the outer leaf color began to fade, the outer leaves of the base became yellow, the leaf clumps turned from vigorous growth to closed growth, and the heart leaves extended to be flush with the outer leaves (commonly known as "flat mouth"). The autumn cabbages in the Jiang and Huai areas can be harvested 30 to 40 days after planting. It takes 50 to 60 days to harvest the plants; the spring cabbage must be harvested before the convulsions. It takes only 40 to 60 days to plant and harvest in South China.
