Is Four Seasons Choy Sum easy to grow? What are the precautions for cultivation?

Four seasons cabbage is easy to plant, when planting, we should pay attention to the choice of planting season and variety, when sowing seedlings to choose sunny and warm weather sowing, summer high temperature season to cover shade net or straw, planting to grasp a reasonable density, fertilizer and water management to grasp well.

Four seasons cabbage is still very easy to plant, and it is also very nutritious, in the market is also better, four seasons cabbage in the planting or to pay attention to insect control work, this kind of vegetables are particularly easy to attract insects, do a good job of watering on it.

It is not easy to plant, planting this plant must control the temperature in the greenhouse, but also control the humidity, must be fertilized frequently, must be often pesticide, pay attention to keep warm.

It is difficult to grow, because the temperature and humidity requirements of seasonal vegetables are very large, so in the process of planting, we must pay attention to controlling the temperature and humidity.

This vegetable is easy to grow and sells well, so be careful when planting it, you can't water too much water at first, because the plant is annoying.

Very difficult to grow. When planting, you must choose the right temperature, only the right temperature to grow the four seasons cabbage will be very good.

Cabbage-type rape is formed by long-term selection and domestication of Chinese cabbage varieties that are easy to sprout, and its main edible organ is cabbage-type rape. Chinese cabbage can be cultivated and eaten all year round. The texture is tender and delicious.

In recent years, its planting area and scope have been expanding, and it has played a good role in increasing vegetable varieties and adjusting weak surpluses. The precautions for the cultivation of cabbage in all seasons are introduced as follows for the reference of local farmers and friends.

1.Cultivation season and variety selection. Although Caixin is an annual vegetable production, it is necessary to select local varieties and the best sowing date according to the specific situation. At present, there are in the country.

Four. 9. Hybrid, semi-early, 60-day-old Chinese cabbage varieties.

2.Sowing seeds and raising seedlings. Oilseed rape sown in early spring should be sown on land with high organic matter content, sunny, and highly arid, with full sunshine, warm climate, or at the end of a cold spell; Summer and autumn sowing should be covered with shade nets or straw to cool the rainfall and prevent soil compaction.

The seed dosage of 667 m 2 is kg, and the seedlings can emerge 3 days after sowing. After the seedlings are sown, the weak seedlings that are too dense should be removed in time, and then separated by 2-3 times to keep the seedling spacing even. When seedlings have true leaves, they are watered with 15% diluted human manure and then once a week with the aim of keeping the soil moist.

Chinese cabbage can also be sown directly, especially in the hot and dry season.

3.Reasonable dense planting. Combine before planting.

667 square meters, 750-1000 kg of rotting manure. When the seedlings have 4-5 true leaves, they should be planted in time, and the planting density depends on the shape of the variety, the cultivation season and the purpose of cultivation. Generally, the early-maturing varieties cultivated in summer are mainly harvested flowering plants, which have fast growth, short growth period, small plants, suitable for dense planting, and the plant row spacing is 13 cm to 16 cm.

The mid-to-late maturing varieties cultivated in spring and autumn tend to have a long growth period, large plants, suitable climate and large growth, and should not be planted too densely, and the plant spacing should be 16 cm to 20 cm.

4.Fertilizer and water management. After planting, we apply some root fertilizer and then top dressing with manure every 3-4 days.

The aromatic content is gradually increased from 15% to 30%-40%. When planting early-maturing varieties, they should be watered to keep the soil moist. By the time the cabbage is flowered, the plant grows vigorously, the cauliflower grows normally, and there is no need for top dressing.

If the cauliflower grows slowly and the cauliflower picking amount is small, a heavy fertilizer should be applied in time to promote the growth of the cauliflower. After the main cauliflower is harvested, if the side ditch needs to be harvested, it should be topdressed once in time, and 10 kg of urea should be applied at 667 m2 in general.

5.Pest and disease control. The diseases of cabbage heart are mainly viral diseases, especially in summer and autumn; The main pests are aphids, filter moths, and vegetable borers, which should be controlled in time.

6.Harvest. The harvesting standards of Chinese cabbage should be strictly controlled.

Generally, the top of the leaf is flush with the top of the high leaf, and the first opening of the flower buds, which is the so-called flowering time, is the best time to harvest. If you want to continue harvesting the side stems, you can cut off the main flowers on the 2nd-3rd leaf (node) at the base of the plant and cut them 1-2 nodes lower for a single harvest.

The profit of Four Seasons cabbage sum in the market is still very high, because many people like this kind of vegetable very much, ** is still relatively high, and it is also very convenient when planting, as long as you pay attention to fertilization and watering.

The profit of this dish is not very high, because the popularity is not high, no one buys it, so there are not many people who grow it. When planting, it should be noted that it uses a lot of water, and it is a plant that prefers a shady and cold environment.

Its value is still very high. Pay attention to its heavy soil, but also pay attention to its spacing distance, whether its roots and seedlings are robust.

It can be cultivated separately throughout the year. When the leaves, be sure to thin the seedlings as soon as possible, and for some dense weak seedlings must be carefully removed. When planting, the land must be sorted out in time

Be sure to pay attention to timely water replenishment to ensure that the soil is moist. It grows especially vigorously during the formation of the cabbage, so be sure to reduce the number of fertilizers. In the market, cabbage has been sold for 7 yuan a catty, and some vegetable farmers have earned more than 10,000 yuan in net profits from planting one acre of land.

<> water spinach can be grown in all seasons. Water spinach open-air planting can be carried out in Tongru spring to summer, generally planted in the middle and lower reaches of the Yangtze River in April to October, planted in the north in April to July, autumn and winter can be planted in greenhouses, generally planted in October to December, 40-60 days after sowing can be burned in turn to harvest and eat.

Attention to details].

1. Water spinach likes high temperature and humidity environment. Seed germination requires more than 15; The axillary bud germination of the seed vine must be kept above 30 in the early stage, so that the budding can be quickly and neatly; The suitable temperature for vine leaf growth is 25 30 °C, and the higher the temperature, the stronger the vine leaf growth, and the shorter the picking interval. Water spinach can withstand 35 to 40 high temperatures; Below 15 vines grow slowly; 10 The growth of the vines below stops, and they are not tolerant to frost, and the stems and leaves die when they are exposed to frost.

The temperature of the vine should be kept at 10 15, and there should be a high humidity, otherwise the vine is easy to freeze to death or wither.

2. Water spinach likes high air humidity and moist soil, the environment is too dry, the vine fiber increases, and the coarse age is inedible, which greatly reduces the yield and quality.

3. Water spinach likes sufficient light, but it is also more adaptable to dense planting. Water spinach does not have strict requirements for soil conditions, but because it likes fertilizer and water, it is still better to have a more viscous and heavy soil with strong water and fertility retention. The leaf tips of water spinach grow in large quantities and rapidly, requiring a large amount of fertilizer, strong fertility tolerance, and a particularly large need for nitrogen fertilizer.

4. Disease prevention and control.

Wheel spot disease and brown spot disease are two common diseases of water spinach.

Prevention and control methods: 1) Reasonable fertilizer and water. According to the characteristics of the variety, fertilize reasonably, increase the application of rotting organic fertilizer, pay attention to the combination of nitrogen, phosphorus and potassium to prevent the defertilization of vegetable plants; Water reasonably, do not over-irrigate, drain water in time after rain to reduce humidity.

2) Remove old leaves. Crop rotation for more than 2 years should be implemented in seriously diseased fields, and diseased old leaves at the bottom of vegetable plants should be removed in time.

3) Pharmaceutical prevention and control. At the initial stage of the disease, you can choose to spray 1200-1500 times of 25% rust wettable powder, 1000-1300 times of 50% promethane wettable powder, 600 times of 70% mancozeb wettable powder, 500-600 times of 65% zepzeb wettable powder, 600 times of 70% thiophanate-methyl wettable powder or 500 times of 75% chlorothalonil wettable powder. Spray once every 7-10 days, and take the drug 3-4 times.

Sock beams. 4) Clear the garden in time. After harvesting, remove the diseased residues in time, turn the soil deeply, and eradicate the weeds in the field.

1. Cultivation season and variety selection. Although choy sum is an annual production of vegetables, all localities should choose suitable local varieties and the best sowing date according to the specific situation. At present, the improved varieties in China include Sijiu cabbage, hybrid cabbage, semi-early and 60-day cabbage.

2. Sow seeds and raise seedlings. For early spring sowing cabbage, it is advisable to choose sunny and dry plots with high organic matter content as seedbeds, and choose sunny and warm weather or the end of the cold wave for sowing. Sowing in the summer and autumn high temperature season should be covered with shade nets or straw to cool down the rainfall and prevent soil compaction. The amount of 667 m2 is kilograms, and the seedlings can emerge 3 days after sowing.

After the true leaves of the seedlings, the weak seedlings that are too dense should be removed in time, and the seedlings should be interspersed 2-3 times in the future to keep the seedling spacing even. When the seedlings have 1 true leaf, they should be watered with 15% thin human manure and once a week thereafter, and the soil should be kept moist. Choy sum can also be seeded, especially in the hot and dry season.

3. Reasonable dense planting. Before colonization, combine whole. 667 m2 with 750-1000 kg of manure for decaying.

When the seedlings have 4-5 true leaves, they should be planted in time, and the planting density should be determined according to the variety form, cultivation season and cultivation purpose. Generally, the early-maturing varieties cultivated in summer, mainly harvested cabbage, grow fast, have a short growth period, small plants, and should be planted densely, and the plant row spacing should be 13 cm to 16 cm. The middle and late maturing varieties cultivated in spring and autumn tend to have a long growth period, larger plants, and a suitable climate, large growth, and most of them have side sprouts, so they should not be planted too densely, and the plant row spacing is better than 16 cm and 20 cm.

4. Fertilizer and water management. After planting, some root fertilizer is applied, and then top dressing is done with manure every 3-4 days, and the strong aroma is gradually increased from 15% to 30%-40%. Early maturing varieties should be watered in hot and dry weather when planted to keep the soil moist.

In the formation period of cabbage, the plant grows vigorously, and the rapeseed sprout develops normally, so it can not be topdressed. If the growth of rapeseed sprouts is slow and the sprouts are small, a heavy fertilizer should be applied in time to promote the growth of rapeseed sprouts. After the main vegetable sprouts are harvested, if the side sprouts need to be harvested, they should be topdressed once in time, generally 667 m2 and apply 10 kg of urea.

5. Pest control. The diseases of choy sum are mainly viral diseases, especially in summer and autumn. The insect pests are mainly aphids, filter moths, and cabbage insects, which should be controlled in time.

6. Harvesting. The harvesting of cabbage sum should be strictly mastered by the standard, generally the rapeseed sprout is flush with the tip of the tall leaves, and the flower buds are beginning to open, that is, the so-called full mouth flower is the appropriate harvest period. If you want to continue harvesting the side strangle, you can cut the main flower at the 2nd to 3rd leaf (node) at the base of the plant, and cut it 1-2 knots lower at one harvest.
