Why do farmers give bok choy bunches of leaves?

In order to prevent it from getting cold, because it grows better, it is said to be leaves

The temperature of Chinese cabbage in autumn and winter cultivation has dropped significantly at the end of balling, photosynthesis has been very weak, and the leaf bulb has basically grown, but as long as the temperature is 0 51, the nutrients in the outer leaves will continue to run to the bulb leaves, so it is advisable to take the measures of "bunching leaves" (commonly known as "bundled vegetables") to increase the soil temperature, promote the transfer of nutrients in the outer leaves and the enrichment and weight gain of the leaf bulbs. In addition, the "bundle of vegetables" also has the advantages of preventing the leaf bulbs from freezing and making it easy to harvest and transport. The cabbage is bunched when the early frost arrives, and the specific method is to pick up the outer leaves, wrap the leaf balls, and tie the upper part of the leaf balls with ropes about 10 days before harvest.

Because bunching leaves on bok choy will make bok choy grow better in the later stages.

Bunching leaves on bok choy can make bok choy grow stronger and look better.

Because in this way, the bok choy will grow bigger and better, which will help in growth.

This may be done in order to make the cabbage grow well.

In order to protect the leaf bulbs from frost, the leaves are bundled before harvesting.

This can make the cabbage more compact and beautiful, and can protect against cold.

Because bunching leaves on bok choy when growing vegetables can make bok choy grow better.

Frost bundles cabbage, small snow cellar.

The Jiangnan area is now easy to tie, loose, in order to prevent winter freezing, after New Year's Day, it has to be tied tightly.

Farmers plant Chinese cabbage, in the later management, there is a very important technical link, it is to bunch the leaves of the cabbage.

Chinese cabbage bunch leaves, also known as bundle of vegetables or tie vegetables, it is in the late stage of Chinese cabbage balling, before the arrival of the local early frost period, with straw or string to pick up the outer leaves of Chinese cabbage, etc., and tie the measures at 2 3 places of the leaf ball. The bunching of leaves is generally carried out 10-15 days before the harvest of Chinese cabbage.

What are the benefits of the cabbage bunch leaves?

First of all, it can promote cabbage wrapping and prevent frost damage to cabbage in the open air. The bundle leaf closure promotes the transfer of nutrients from the outer leaves of Chinese cabbage to the heart leaves, which is conducive to the softening of the heart leaves of Chinese cabbage and promotes the centering.

Secondly, after the Chinese cabbage passes through the bunched leaves, the sun hits the surface, which improves the ground temperature and the fertilizer absorption ability of the roots, and the Chinese cabbage can also grow slowly.

Third, after the Chinese cabbage has been bunched with leaves, if it is planted in the field, it is conducive to interplanting wheat, rape, spinach, etc., which can improve the utilization rate of soil.

Chinese cabbage is propagated from seeds, and leaves cannot be propagated in production.

Chinese cabbage leaves cannot be planted directly. If test-tube multiplication is used, the green part is generally used.

Chinese cabbage propagation and cultivation techniques.

Fertilization and land preparation: 2000 to 3000 kg of organic fertilizer per mu, 60 kg of potassium sulfate compound fertilizer as base fertilizer. Deep ploughing 30 to 40 cm, leveling and raking fine after ridge spacing, ridge spacing 60 cm, ridge standard for the bottom width of 35 to 40 cm, neck width of 20 to 25 cm, ridge height of 20 cm.

The soil ridges are compacted to facilitate sowing.

Watering to create moisture: When the soil moisture is insufficient, it is necessary to water and create moisture before preparing the land after applying basal fertilizer.

Fine base celery sowing: The main sowing method of Chinese cabbage in autumn is live broadcasting, which is divided into two methods: strip sowing and hole sowing.

Strip sowing: open a shallow ditch to a depth of centimeters in the middle of the ridge, spread the seeds evenly in the ditch and then cover the soil and compact, with a seed amount of about 120 grams per mu. You can also use cabbage seeding machine, sowing in the middle of the top of the ridge, with a seed amount of 80 to 100 grams per mu, and the seeding machine should be equipped with soil covering facilities.

Hole sowing: at the top of the ridge according to about 55 cm hole spacing, and the soil Boshen ridge vertical direction to open a 10 to 15 cm long, deep to centimeter ditch hole, each ditch sowing 5 to 6 seeds, after sowing cover fine soil centimeter compaction, 100 to 120 grams per mu of seeds.

Cultivation techniques. Seedlings: 5 to 6 days after the emergence of seedlings, the first seedlings, to the weak and strong, the spacing between the seedlings is 2 to 3 cm; When the Chinese cabbage has 3 to 4 leaves, the seedlings of the strip sowing plot are 8 cm, and about 3 plants are left in each hole when the hole is sown; After another 5 to 6 days, the third seedling is sent.

Seedling: Seedlings grow for about 25 days to reach the cluster stage, according to the plant spacing of 50 to 60 cm seedlings, leaving about 2,000 seedlings per mu. If the lack of seedlings is found, it should be replanted in time, and the seedlings should be watered in the afternoon or cloudy day on a sunny day.

Cultivating and weeding: 3 times of tillage, respectively after the second seedling, after seedling setting and in the middle of the rosette. Cultivating combined with weeding.

Reasonable watering: If the bottom moisture is insufficient, water in time after sowing to ensure that the seedlings are strong and strong. After thinning seedlings and setting seedlings, water 1 water each. Initial watering promotes the growth of trees. During the balling period, watering should be carried out in combination with top dressing, and the amount of watering should be large and uniform. In the later stage, appropriate water control promotes the core wrapping.

Timely top dressing: 15 to 20 acres of nitrogen, phosphorus and potassium compound fertilizer per mu at the rosette stage. At the beginning of balling, 30 to 40 kg of nitrogen, phosphorus and potassium compound fertilizer were applied per mu.

No more topdressing within 20 days before harvest. Combined spraying at the rosette stage begins with 1 spray of foliar fertilizer every 7 to 10 days, a total of 2 to 3 times, using a mixture of urea and potassium dihydrogen phosphate, sprayed after 16 o'clock.

Harvest: After mid-November, Chinese cabbage basically stops growing and enters the harvest period. After the beginning of December, it should be harvested in time to prevent frost damage.

The green cabbage and Chinese cabbage are the vegetables that are planted together.

青菜 qīngcài

1) [Green vegetable] The edible part of vegetables is rich in chlorophyll and constitutes an important vitamin and trace element**. Reunion celebration.

2) [greens] A general term for vegetables. The stool is dry, so you should shoot dates and eat more vegetables.

3) [pakchoi] i.e. baby cabbage (brassica chinesis).

Chinese cabbage is not a green vegetable.

Varieties of cabbage include Luxiu cabbage, Tai'an cabbage, Jiaozhou cabbage, festive cabbage, Tianjin staring green cabbage, Yuyi jade Linglong and so on.

Cabbage is green when it is a seedling, and it is very similar to the green cabbage, but it is still different. Baby cabbage is the closest to greens.

In the later stage of Chinese cabbage growth, the weather is changeable and the temperature is gradually dropping. Generally, 10 to 15 days before harvesting, stop watering, lift up the rosette leaves, hold the leaf balls, and then tie the leaves with soaked sweet potato seedlings or cereal grass. Make the core firmer and continue to grow.

2 to 3 days before light snow, it should be harvested in time and dried in the field, and the outer leaves can be stored when they wilt.
