If you want to grow cabbage sum on a large area, which variety should you choose?

The first point is to choose the kind of breed with a good reputation, which is very good, and the second point is to choose the kind of breed with a high survival rate, then it is very good, and you should pay attention to these things when choosing people.

No. 19 Sijiu Caixin is bred by Guangzhou Vegetable Research Institute of Guangdong Province. The plant is compact and has strong growth potential. The basal leaves are semi-erect, the leaves are long ovate, blue-green, and the petioles are short.

4 5 leaves begin to sprout, the main sprout internodes are sparse, the sprout is 18 cm high, light green, shiny, and the single sprout weighs 35 grams.

Large-scale planting should be selected Sijiu cabbage, the quality of this variety is particularly good, and the yield is particularly high, and it is also easy to take care of.

Varieties that are not easy to flower, because of the season, there are still some deficiencies in temperature control, choose some that are easier to plant.

To grow choy sum, you should choose the variety of choy sum according to the local climatic conditions and cultivation season. It is mainly caused by the different temperature inductions of different varieties of cabbage with different attributes. Under the same low temperature conditions, the more early-maturing varieties are more likely to pass the vernalization stage.

Choy sum has a wide range of adaptation to temperature, and can be cultivated under the condition of average temperature of 3-28, but there are obvious differences in the adaptability range of varieties with different ripeness to temperature. The formation period of cabbage sum is about 15 (day temperature 15-20, night temperature 10-15) is optimal.

<> cabbage sum is simple to grow, has a wide range of adaptability, does not have strict requirements for temperature and light, is cold and heat resistant, and can be planted in an environment with an average monthly temperature of 4-28. The suitable temperature for seed germination and seedling growth is 25-30, and the appropriate temperature for leaf growth and rapeseed formation is not strict, and the average temperature is 10-28 degrees Celsius to grow smoothly.

Under the same low temperature conditions, early-maturing varieties of cabbage sum are easy to undergo vernalization, while late-maturing varieties need a longer time to vernalize. In the actual planting, due to the underdeveloped root system of cabbage, the old seedlings are transplanted with too many injured roots, the recovery growth is slow, and it is easy to sprout in advance, so the seedling age should not exceed 30 days, generally in 20-25 days.

The seedbed should be sandy or loam, with plantar fertilizer. The sowing amount of seedbed per mu is about kilograms, and the seedlings raised can be planted on 7 8 acres of land. After the true leaves, appropriate seedlings were tapped and a small amount of human feces and urine were applied in combination with the seedlings.

Due to the underdeveloped root system of cabbage, such as the seedling period is too long, the planting of cabbage can be said to be all over the country, regardless of the north and south, all provinces in the country have the choice to plant cabbage, and the growth of cabbage, the adaptability to the soil is very strong, as long as the soil is fertile, permeability is good, water and fertilizer are sufficient, you can plant cabbage and get the right time to sow seeds, cultivate strong seedlings along the Huai area generally in late August to early October. Select the seedbed (the stubble before the seedbed should avoid cabbage), apply sufficient base fertilizer, turn the soil deeply, level the furrow, the width of the furrow is 1 meter, the length is not limited, the uniform sowing is sowing, and the seedbed is sown per mu.

It should be selected according to the local climate, and it must be in a high temperature state when cultivating, and the surrounding temperature must reach a certain height so that it can be cultivated.

The method of cultivation in the open field, this cultivation method is very good, and it should be in September and October, so that the yield will increase.

The soil is deeply ploughed and whitened, and sufficient basal fertilizer is applied. The base fertilizer is generally 1000-1500 kg of decomposed organic fertilizer and 5-10 kg of potassium sulfate per mu; or 750 kg of chicken manure and 20 kg of compound fertilizer. The furrow is generally a meter wide, 20-30 cm high, and has a turtle back shape.

5. The leaves of Sijiu Caixin are oblong, yellow-green, and the petioles are light green. The main sprouts are about 22 cm high, transverse diameter cm, yellowish-green, with few lateral sprouts, and early sprouts. Medium quality.

Heat-resistant, moisture-resistant, disease-resistant, suitable for high temperature and rainy planting, the growth period is 28 to 38 days, and can be harvested continuously for about 10 days.

6. Chi Cai Xin Chi Cai Xin, also known as Gao Cai Xin, is a well-known specialty vegetable variety in Zengcheng, Guangdong, known as "the king of vegetables, the crown of cabbage". Because of the special geological skin of Zengcheng, cabbage can grow into a 1-meter-high vegetable tree, but its skin is still brittle and soft, with thick stems and leaves, whether it is fried or boiled, it is very fast to cook, and it is fresh and sweet to eat.

If there is fertile soil, apply some organic fertilizer, choose good quality seeds, water more and fertilize frequently, control pests and diseases, and weed.

It is necessary to grasp the time of planting, carry it out in the spring, keep the outside temperature at about 25 degrees, and pay attention to timely watering.

If you want to plant water spinach with high yield, in fact, the main thing is to do a good job of composting and fattening and fertilizing in time, because this vegetable is a fast-growing vegetable, do a good job in this fattening management, and then do a good job in preventing pests and diseases to get high yields.

When planting, don't let the water spinach grow too densely, so that the water spinach will grow better. After planting, it is necessary to water first, and then apply a little organic fertilizer to supplement nutrition;

When cultivating and weeding, fertilizer should be applied at the same time, and then it should be watered every 4 days or so;

It is necessary to remove the weeds in the field in a timely manner to avoid these weeds and water spinach competing for nutrients and making the water spinach grow poorly;

During the harvest period, after each harvest, 1 mu should use kilograms to kilograms of compound fertilizer;

If the soil is too dry, it should be watered promptly. And every time you water, you must water enough water, and you must do it wet and thorough every time.

Choy sum can be broadcast live, and seedlings can be transplanted, but seedling transplantation is suitable. The seedling time of vegetable hearts is usually 18-25 days, and the late-maturing varieties do not exceed 30 days. Early maturing varieties have a shorter time.

Winter and spring seedlings have a long low temperature time, after soaking in warm water for 4 hours, wrap them in a damp cloth, keep them moist, germinate at the right temperature, and then sow seeds until the seeds are peeled. Early-maturing varieties and medium-maturing varieties are sensitive to temperature and develop quickly. Early development should be prevented at the seedling stage, and late-maturing varieties have strict temperature requirements, so they should be sown in a timely manner, and they should choose sunny and warm weather when sowing, and do not sow in cold snaps or cloudy days.

Sowing seeds at this time will produce cold shoots, and the seedlings will bloom too early, and the plants will become fragile if they are harvested early. In summer and autumn, there is a lot of high temperature rain on the mother meat, and the mother meat should be shaded by a plastic greenhouse to protect from the rain.

In early spring, saplings should be given less, and in summer and autumn, small water should be given frequently. One to four or five true leaves, the leaves are intact. The leaf oil green petiole is blue-green when it grows vigorously and has proper development.

At this time, a certain amount of vegetative area and a certain development foundation are the most timely period for the main meal. The colonization of the vegetable mind is the key to the success or failure of planting. Reasonable dense planting is the basis for increasing yield, early maturing varieties should be planted densely, and medium and late maturing varieties should be appropriately rare.

Plum dense plants with narrow leaves and small swelling, and Li Ji plants with round leaves and large plant degrees. The spring river growth environment is out of date, so it should be close, and the autumn growth environment should be negligent when the growth environment is suitable. The things that can only be obtained by the main push are very dense, and the main side can rarely get them.

Avoid heavy rain when sowing, cover the mass with straw or decaying organic matter after sowing to prevent rain erosion and keep the seedbed soil moist. After a small number of seeds have germinated, the mulch can be removed. According to the actual situation of the distribution of vegetable myocardium, fertilization is applied according to the habits such as absorption area, absorption capacity, and growth rate.

Generally, the corrosive and delicate texture of the swamp is used as the base fertilizer. During the formation of vegetables in autumn, phosphorus and potassium fertilizers should be appropriately applied to improve soil fertility and effectively improve the quality of vegetable planting through fully fermented biogas slurry. Vegetable myocardium is relatively shallow, the leaf area in the middle and late stages is large, and the yield is increased in high temperature weather, so it is necessary to keep the soil moist throughout the growth stage of the vegetable heart, water frequently, avoid flooding, and discharge the soaking water in time on rainy days.

The first point: how to choose the variety and the time of sowing.

It is best to choose early and medium ripening varieties of cabbage, such as Sijiu 19 and Baoqing 60, which are generally cultivated in the open field, and the best time for sowing is from September to October.

The second point: how to raise seedlings.

It is best to choose a higher terrain for the seedling plot of autumn cabbage, which is ventilated and cool, and is easy to drain and irrigate. 3,000 kg of fully decomposed organic fertilizer should be applied per mu, and then the soil fertilizer should be mixed.

The third point: colonization.

Precautions before planting, 3000 kg of fully decomposed organic fertilizer should be applied per mu, the soil and fertilizer should be mixed evenly, raked flat, and can be made into a small high furrow to facilitate future drainage.

Must apply sufficient base fertilizer, in the growth period to timely top dressing, in the summer and autumn cultivation of cabbage, high temperature and rain is not conducive to the growth of the period of top dressing, pay attention to the application of base fertilizer, to the base fertilizer. Top dressing must master the choice of diligent application, early application, and thin application, pay attention to the light in the early stage, heavy in the middle and late stages, generally to the fast-acting nitrogen fertilizer, but also to increase the appropriate phosphorus and potassium fertilizer to improve the yield and quality of cabbage.

There are two kinds of water spinach, and there are two kinds of water spinach, and the north mostly reproduces with seeds, and the commonly used varieties are as follows. Water spinach can be cultivated in the open field from spring to summer, and the sowing time is: December to February of the following year in Guangzhou, April to October in the middle and lower reaches of the Yangtze River, April to July in the northern region, and Shenyang can be sown in mid-April.

If cultivated in greenhouses, greenhouses, and small sheds according to market needs, annual production can be achieved, and the market can be achieved at any time.

The length is only, there are many varieties of cabbage, now it belongs to winter, cabbage is the easiest to moss and flower, the vegetable field must first apply sufficient base fertilizer, sowing is almost more than 40 days or so to pick up, seedlings transplanting can pick cauliflower in more than ten days, the temperature should be 25 30 during the management period; The temperature required for the leaf growth period is slightly lower, the suitable temperature is 15 20, the growth is slow below 15, and the growth is more difficult above 30. The suitable temperature of the formation period of rapeseed is 15 20, when the day temperature is 20 and the night temperature is 15, the rapeseed sprout develops well, and can be planted in the environment of about 28, and the most suitable temperature for growth is 15 25.

<> planting Guangdong cabbage can be cultivated in a large area of canopy film, so that it can be planted and grown all year round. Similarly, in the north, it can also be planted with canopy film, as long as the vegetables are sweet and crisp and the moss is neat. If these seeds are sown in winter and spring, the cabbage will not only be as slender as a toothpick, but will also eat like old grass, thick and scum, and completely lose its commodity value.

On the contrary, the seeds of cabbage in winter and spring are like 60 or 80 days old, and the cabbage sum is a genus of Brassica in the cruciferous family.

One- and two-year-old herbaceous plants. It is suitable for cultivation in the warm regions of the south and is one of the specialty vegetables of the south. It can be sown all year round, and is called "after the dish" by consumers.

It is also suitable for cultivation in colder climatic conditions, and the root system is not deep, and there are many small hairy roots. 5-8 days after sowing cotyledons, 14 to 18 days is the seedling stage, the germination stage and seedling stage growth temperature is best 25-30 degrees, 7-21 days to the leaf growth period. When it comes to the formation period of cabbage, the most suitable temperature is a specialty of Guangdong and Guangxi, which can be planted all year round, with a short growth cycle, crisp and tender quality, unique flavor, rich nutrition, and my family basically fries a plate every day.

The amount of seeds per mu is 6-10 dry grams, sowing is generally sown with strip sowing, the row spacing is about 27 cm, the plant spacing is about 17 cm, each hole accounts for 3-4 grains after sowing and watering after covering the soil, 7-9 days can be seedlings, but also sown.
