How and when to grow Brussels sprouts

Sowing is done in late July and early August every year. Prepare the seedbed: when sowing, you should choose a plot that has not been planted with cruciferous vegetables in the past three years, and first fertilize the land to ensure that the plot is loose and fertile, and apply fertilizer and compound fertilizer after decay.

Sowing method: After the seedbed is treated, the prepared seeds can be sprinkled on it, and it can be sown directly. Pay attention to the density of the spread.

25 grams of seeds per mu. Post-planting management: After the seeds are planted, they should be covered with a layer of soil in time, the bed surface should be covered with a shade net, watered once, and the furrow surface should be moistened.

When the seedlings begin to emerge, remove the shade net.

Seedling management: When the seedlings grow two true leaves, the seedlings should be divided in time, and the area of the transplanted seedbed should be large enough, which is 10 times the area of the current seedbed. Apply nitrogen fertilizer in time during the seedling raising period, and water frequently to moisturize.

It is also necessary to drain the stagnant water after rain. In addition, attention should be paid to the prevention and control of pests and diseases.

Summary. Brussels sprouts like to be cool, and it is best to plant them in spring and summer, and each region can be adjusted according to the specific situation. In order to increase the germination rate, prepare warm water at 40-50 degrees Celsius and soak the seeds for half an hour, stirring while soaking.

Prepare the seedbed, mix with organic fertilizer, mix evenly, level and rake finely. Sow the seeds and cover the soil with water. When the seedlings grow 5-6 true leaves, they can be transplanted and planted, and after planting, they should be watered enough, do a good job of top dressing, and pay attention to weeding and pruning.

When is it good to plant in Dalian.

The sowing period of spring radish should be strictly controlled. The sowing date can be arranged according to the production level and actual demand of vegetable farmers, and the greenhouse cultivation can generally be sown from the end of January to the middle of February, and the harvest will begin in early April; It can be sown from mid to late March to early April and harvested from mid to late May to early June. If the small arch shed is cultivated with mulch, the sowing date can be advanced to the first half of March. Autumn radishes, usually sown in mid to late July.

Harvested in mid-September, if the weather is suitable, the yield is high and the quality is good; Summer and autumn turnips, sown in May-June and harvested in July-August. Radish seed planting technologyGrowing radish is based on deep soil, good water retention and drainage, loose and breathable sandy soil. The pH value of the soil is more suitable.

The absorption of nutrients by radish was the highest in potassium, followed by nitrogen and the least phosphorus. For every 1000kg of radish produced, it absorbs about nitrogen, phosphorus, and potassium, and the absorption ratio of nitrogen, phosphorus, and potassium is.

Brussels sprouts are grown in different areas depending on the region in which they are produced. The suitable sowing period in the Yangtze River Delta Plain, which is dominated by open-field cultivation, is from late June to mid-July, and from November to March of the following year**. In the alpine areas, it is advisable to sow seeds in April in the spring.

Seedlings of Brussels sproutsCultivating strong seedlings is the key to Brussels sprouts cultivation. Because the seeds are mostly hybrid generation, the most expensive, summer and autumn sowing should be rainproof shelter and shade net under the hole tray seedlings, in order to improve the seedling emergence rate, is conducive to cultivating strong seedlings and reducing seed costs.

If the seedbed is uncovered, it is necessary to choose a plot with good ventilation and convenient drainage and irrigation, the amount of seeds per mu needs to be 25 grams, the sowing bed area needs to be 4 square meters, the soil is shallow after sowing, and the black shade net is directly covered on the bed surface, and then watered thoroughly to keep it moist, and when the seeds begin to emerge, remove the shade net in time, in order to cool down and prevent heavy rain.

The low flat shed on the furrow continues to cover the shade net, the day cover is unveiled at night, the seedling emerges to the planting period, it needs to be planted 1 time, the transplant bed area needs to be about 35 square meters to 40 square meters, and when there are 5 to 6 true leaves, it is planted in the field. Generally, the seedling age is 35 to 45 days.

1. Planting time.

Brussels sprouts like a cool climate, and the requirements for sowing and planting time are not high, and they can be planted and cultivated in the open air in spring, summer and autumn. In general, it is best to choose spring and summer. The climatic conditions vary from region to region, so the timing of sowing depends on the actual situation.

2. Seed treatment.

The seeds of Brussels sprouts are more expensive, so the germination rate must be guaranteed. In order to improve the germination rate, it is necessary to treat the seeds in advance, prepare warm water at 40-50 degrees Celsius, soak the seeds for about half an hour, and stir while soaking.

3. Prepare the seedbed.

It is generally sown and seedlings are planted, and then transplanted and planted, so the seedbed should be prepared before sowing. The seedbed is selected from sandy loam soil with flat terrain, convenient drainage and irrigation, and fertile soil, mixed with organic fertilizer, and leveled and raked finely.

Fourth, carry out sowing.

Sow seeds at a certain interval on the stool, cover the seeds with centimeters of thin soil, and water the soil thoroughly and cover it with a shade net.

5. Transplanting and planting.

When the seedlings grow 5-6 true leaves, they can be transplanted and planted, tidy up the soil in advance, apply enough base fertilizer, dig a small pit in the soil, transplant and plant the seedlings, and water them after transplanting and planting, in order to promote the rapid growth of seedlings, they should do a good job of top dressing, and also pay attention to weeding, pruning and pruning.

1. Planting time.

Brussels sprouts prefer cooler climates and are not very demanding when sowing and planting. They can be grown in the open air in spring, summer, and fall. In general, it is better to choose both spring and summer. Different regions have different climatic conditions, and the sowing date should be determined according to the actual situation.

2. Seed treatment.

Brussels sprouts are expensive, and the germination rate must be guaranteed. In order to improve the germination rate, it is necessary to treat the seeds in advance, prepare warm water at 40-50 degrees Celsius, soak the seeds for about half an hour, and stir while soaking.

3. Prepare the seedbed.

Generally, seedlings are sown and then transplanted, so the seedbed should be prepared before sowing. The seedbed should be sandy loam, flat terrain, convenient drainage and irrigation, fertile soil, mixed with organic fertilizer, leveling and raking.

Fourth, carry out sowing.

Sow seeds at intervals of each beat. After sowing, cover with a thin layer of soil, fill the soil with water, and cover with a shade net. When the seedlings grow to 5-6 true leaves, they can be transplanted and planted.

Tidy up the soil in advance, apply sufficient base fertilizer, dig small holes in the soil, transplant seedlings, and water after transplanting. In order to promote the rapid growth of seedlings, top dressing should be carried out, and attention should be paid to weeding and pruning.

Brussels sprouts need to be planted according to the characteristics of the variety and the cultivation method. In Shanghai, early-maturing varieties are the main varieties, which are sown in late July and early August every year. Early and medium-ripening varieties are mostly selected in the protected area, and they are sown from late July to early September.

The planting time and cultivation methods of Brussels sprouts are as follows:

1. Temperature: The most suitable environment temperature for its growth is 12-20, and the growth temperature should be kept at about 10 during the seedling period, with a certain cold tolerance, but it needs to be placed in a cool place in summer.

2. Soil: It does not have very high requirements for soil, but it will grow better in soil rich in humus. When preparing the soil, a mixture of garden soil and humus soil should be used.

3. Light: It likes to grow in a cool place, when it is a seedling, it should be covered with a black shade cloth during the day, and it can be uncovered at night, and try to avoid direct sunlight.

4. Fertilizer: In the process of breeding, nitrogen fertilizer should be applied to it after planting, and the amount of fertilizer should be adjusted according to its growth, which should be applied once every five days or so.

The planting time and cultivation methods of Brussels sprouts are as follows:

1. The planting time of Brussels sprouts varies depending on the production area. The suitable sowing period for the Yangtze River Delta plain area is from late June to mid-July, from November to March of the following year**, and the alpine area should be sown in spring in April, from September to October until February and March of the following year, and in spring sowing seedlings in the protected area from January to February, planting in March-April, and May-June**.

2. Cultivating strong seedlings is the key to the cultivation of Brussels sprouts. Because the seeds are mostly hybrid generation, the most expensive, summer and autumn sowing should be rainproof shelter and shade net under the hole tray seedlings, in order to improve the seedling emergence rate, is conducive to cultivating strong seedlings and reducing seed costs. If the seedbed is unplanted, it is necessary to choose a plot with good ventilation and convenient drainage and irrigation, and the amount of seed per mu needs to be 25 grams.

3. The sowing bed area needs to be 4 square meters after sowing shallow soil, directly covered with black sunshade net on the bed surface, and then watered through water to keep it moist when the seeds begin to emerge, remove the sunshade net in time, in order to cool down the rainstorm and build a low flat shed on the top of the raiser to continue to cover the sunshade net, the day cover is unveiled at night, the seedling needs to be planted 1 time during the planting period, the transplant bed area needs to be about 35 square meters - 40 square meters, when there are 5 - 6 true leaves when planted to the field. Generally, the seedling age is 35-45 days.

4. In addition to the application of sufficient basal fertilizer during the growth period of Brussels sprouts, it is also necessary to divide 4 times into 4 times after topdressing and planting, and apply seedling fertilizer after watering live tree fertilizer for one month to promote the vegetative growth of plants, so that the outer leaves before entering the balling stage reach about 40 pieces, the third top dressing is carried out in the bud bulb expansion period, and the fourth time is carried out in the bud bulb harvesting period.

5. Each time the liquid fertilizer is usually watered with urea solution, and 10 kg to 15 kg of urea per mu is used each time to apply in holes or furrows, combined with watering. Attention should be paid to cultivating and weeding and rhizosphere soil cultivation, so as not to affect the formation and expansion of bud bulbs when the plant swings when it is windy and rainy. In windy areas, bamboo poles and branches are used to set up scaffolds.

Once the leaflet ball is produced in the middle of the stem, the lower leaf should be removed, which is conducive to ventilation and light transmission, promote the development of leaf balls, and it is convenient to harvest the leaf balls.
