Broccoli planting time and method, broccoli planting time and method

Broccoli can be planted in the open air after Qingming in spring, around April, the temperature is just right for broccoli to germinate, and autumn is generally in late summer and early autumn. It is cultivated in spring and autumn in Beijing. Generally, the seeds are sown in early April, harvested in late May, sown in early autumn in August, and harvested in early November.

7 health benefits of broccoli1Prevent cancer. Like cruciferous vegetables like cauliflower, Brussels sprouts, white radish, and cabbage, broccoli has anti-cancer and immune-boosting effects.

2.Lowers blood lipids. Broccoli is rich in soluble fiber, which helps remove waste from the intestines, lowers cholesterol levels, and controls blood lipids.

3.Allergy prevention. The active substances in broccoli have been found to reduce the effects of allergens on the human body and reduce the risk of allergies.

4.Antioxidant. Broccoli is rich in strong antioxidants such as carotenoids, lutein, zeaxanthin, and carotene.

5.Strong bones. Broccoli is rich in calcium and vitamin K, two nutrients that play an important role in bone health and preventing osteoporosis.

6. Protect the heart. The sulforaphane isothiocyanate in broccoli has an anti-inflammatory effect, which can prevent blood vessel damage and protect the heart. 7.

Help**. Buried broccoli is rich in dietary fiber, which is conducive to digestion, prevents constipation, lowers blood sugar, and prevents overeating, so as to achieve the purpose of **. Extended Information:

Cultivation conditions of watercrilla: 1Light does not require strict light, but prefers to have plenty of light during growth.

When the light is sufficient, the plant will grow vigorously, and can form a thick curved cavity vegetative body, which is conducive to photosynthesis and nutrient accumulation, so that the flower bulb is compact and compact, the color is emerald green, and the quality is good. Too much sunlight in midsummer is not conducive to the growth and development of this flower. 2.

When the temperature is in the range of 5 20, the higher the temperature, the faster the growth and development of orchid. The optimal germination temperature was 20 25, and the optimal growth temperature at seedling stage was 15 20. Waterlibusa is very hardy to cold and heat.

The optimal temperature for rosette growth is 20 22 and for bulb development is 15 18. When the temperature is higher than 25, the quality of the bulb tends to deteriorate, but as long as it is not damaged by frost, the bulb can still grow slowly at low temperatures of 5 or even lower. Different varieties and seedling ages have very different temperature requirements for vernalization, so it is important to choose varieties in annual cultivation.

3.Cymbidium macroflora requires more water during the whole growth process, especially during the vigorous leaf growth and flower bulb formation period. Even short-term droughts can reduce yields.

Rainy seedlings or high soil moisture are easy to cause diseases such as black rot and black spot. The soil moisture at the flowering stage and the water holding capacity of about 70 to 80% of the field can meet the growth needs.

Broccoli is grown in spring and summer. Before planting, the soil should be loosened and then sown, and watered in time to promote germination, and after the emergence of seedlings, reasonable topdressing according to the growth, and pay attention to the prevention and control of pests and diseases.

1. Planting time Many people think that broccoli can only be grown for one season, but this is not the case. Broccoli can generally be grown in two seasons, in March and July. Planting starts in mid-March and can generally be harvested in early June; If you plant it in early July, you can harvest it in mid-September.

Since broccoli prefers warmer to cooler weather, the harvest in March is generally better than the harvest in July. 2. Planting method 1. Land Broccoli does not have high requirements for soil, and prefers sandy soil, because it likes more breathable soil, and sandy soil will increase the yield of broccoli to a certain extent. The soil needs to be composted in advance, and weeds cannot be left in the soil after being cleared.

The location of the land should be high, the drainage should be convenient, and the soil should be kept in a semi-wet state, which can strengthen the soil permeability, and the soil can be slightly acidic. 2. Light temperature Broccoli has a high demand for sunlight, and good direct sunlight can promote the firmness of flower bulbs. However, if the temperature is too high and you still need shade, the general temperature control at 25 is more suitable for the growth of broccoli.

It is best to control the direct exposure time to about 6 hours, and when the temperature exceeds 35, you should pay attention to heatstroke, otherwise it is easy to sunburn broccoli. 3. Fertilizer and water management Because broccoli grows faster, there will be more fertilizer and water requirements, generally divided into 3-4 times. After the emergence of seedlings need to be topdressed once a week, followed by the second topdressing after the growth of flower bulbs, the next two times to see the growth situation, not ideal twice, ideal once is good.

The amount of water is less in the early stage, mainly after the growth of the flower bulbs should pay attention to maintaining the wetness of the flower bulbs, and it is best to water directly along the connection between the page and the roots.

Broccoli is planted in April in the spring and August in the fall, and the planting methods are sowing seedlings, seedbed management, and transplanting and planting.

1. The planting time of the West Lack Laughing Orchid.

Broccoli likes to grow in a warm environment, according to its growth habits, the most suitable planting time is in spring and autumn every year, generally planted in April in spring, can be harvested in late May, if planted in early August, then can be harvested in early November.

2. Broccoli planting method.

Broccoli generally uses the method of sowing seeds to raise seedlings, soak its seeds in 50 warm water for 25 minutes, select the soil with fertile, loose and breathable and well-drained soil as the seedling bed, mix it with rotting base fertilizer and make furrows, and then you can sow the soaked seeds into the soil.

When broccoli is raising seedlings, it is necessary to keep the soil slightly moist, and the temperature between 20-25 is most conducive to its germination.

When broccoli seedlings grow to 25-30 days, they can be transplanted and planted, and the cultivation soil requirements are good drainage and irrigation, deep tillage layer and loose and fertile soil type, and it is best to bring the seedling soil of the root system to transplant together, do a good job of maintenance and management, and soon the broccoli can grow.

Broccoli conservation management

Broccoli needs sufficient nutrients during the growth process, when cultivating broccoli, it is necessary to fertilize according to the growth state of the plant, when the broccoli grows 6-8 true leaves, nitrogen, phosphorus and potassium compound fertilizer should be applied every other month, and before the broccoli is harvested, it is necessary to spray potassium dihydrogen phosphate on its leaves.

When maintaining broccoli, it is necessary to raise the stove to water the plants when the weather is too hot to avoid the broccoli from drying up due to the lack of water and stuffiness, and at this time to observe the branches and leaves of the broccoli to avoid plant infection and disease, so that the broccoli grows healthily, and at this time can not fertilize the broccoli, so as not to rot the roots.

The main pests and diseases of broccoli are black rot, soft rot, gray mold, cabbage worm, aphid, etc. Prevention and control should strengthen fertilizer and water management, rational planting, crop rotation, etc., scientific and rational use of drug prevention and control.

The planting time of broccoli is generally concentrated in spring and summer, and the planting technology is becoming more and more mature by eliminating the cavity cavity, and farmers have begun to use greenhouses for planting, so that the temperature and humidity can be well controlled, so that the broccoli grows normally, and the temperature should not be too high in the planting process of broccoli, and the amount of fertilizer and water control should also be paid attention to.

The planting time of broccoli is generally concentrated in spring and summer, because the planting technology is becoming more and more mature, there are farmers who have begun to use greenhouses to grow broccoli, which can well control the temperature and humidity of planting, help it grow normally, and can harvest broccoli all year round.

Broccoli planting methods and key points.

1. Soil

When planting broccoli, the requirements for the soil are not very high, it is relatively more sandy soil, generally before planting broccoli, to fertilize the soil in advance, but also to keep the soil in a semi-wet and semi-dry state, take the shirt to enhance the air permeability of the soil, so as to promote the better growth of broccoli.

2. Light temperature

Broccoli needs plenty of light during the growth process, direct sunlight on broccoli can make its flower bulb more compact, and at the same time, pay attention to the temperature is not too high, it is best to control the temperature around 25 to avoid sunburn broccoli.

3. Fertilizer and water management

Because broccoli grows faster, a large amount of fertilizer can be applied, generally 3-4 times a day, a week after the emergence of seedlings to top dressing once, in the broccoli after the growth of flower bulbs to top dressing again, combined with the growth of two times, a small amount of fertilization.

Broccoli planting precautions.

1. Soft rot

In the process of broccoli planting, it is necessary to avoid the phenomenon of rainwater, so that bacteria will enter from the wounds in the roots, leaves and other parts, which will cause the broccoli to gradually rot, and pay attention to drainage in the rainy season.

2. Cabbage worm

During the planting of broccoli, it is necessary to pay attention to the cabbage insects, pay attention to observation, and it is recommended to spray the insecticidal fungus No. 6 with water on the broccoli after it is found.

Broccoli is suitable in March in the spring and around July in the summer.

Planted in March, properly managed, and harvested by early June. If it is planted in July, it can be harvested by mid-September. Nowadays, the cultivation technology is mature, and many farmers choose to cultivate in greenhouses, which can control temperature and moisturize well, so they can eat fresh broccoli all year round.

Physiological characteristics of broccoliBroccoli is similar in morphology and growth habit to cauliflower, but it is robust and resistant to heat and cold. The plant is tall, grows more than 20 leaves and pulls out the flower stem, and the top grows closely grouped into a group of flower buds in the shape of a flower ball, and the flower buds are blue-green, so it is also called broccoli. The leaf color is blue-green, gradually turning to dark blue-green, and the wax powder increases.

The petiole is elongated and narrow. There are two types of leaf shapes: broad-leaved and long-leaved.

Broccoli is usually planted in the fall, grows in the winter, and is normally available on the table after the Spring Festival.

Spring begins to bloom to April and May seeds mature, summer and autumn seedlings in 8-10 months in the high temperature season seedlings, at this time the temperature is generally above 25, sometimes 30-35 high temperature, plus there are heavy rain, hail hazards, so the use of shade net in the open field seedlings, its seedling age is generally 35-40 days, can be used sowing or direct hole seeding, the average seedling period is about 30 days, from planting to harvest 80-90 days, the winter is slightly stronger, the seedling stem thickness of 10 mm can accept the influence of low temperature, complete the vernalization process.

Before sowing, the seedling bowl filled with soil is watered thoroughly, and it can be sown every 1-2 days, the variety uses imported or domestic seeds, using artificial point seeds or mechanical sowing, 10-15 grams of seeds per package, sowing acres of land, can breed 16-170,000 acres, press a small nest in the middle of the seedling bowl with your fingers, and point a seed per small nest (ordinary seeds up to two grains).

Broccoli requires a lot of water throughout the growth process, and even short-term drought can reduce yields, so it needs to be taken seriously.

Broccoli, also known as green cauliflower, is a 1-2-year-old herbaceous plant, native to the eastern coastal areas of the Mediterranean, currently cultivated in the north and south of China, and has become one of the main vegetables in daily life. Broccoli is rich in nutrients, containing protein, sugar, fat, vitamins and carotene, and its nutritional content ranks first among similar vegetables, and is known as the "crown of vegetables".

Broccoli is grown in the following ways: soil conditions, light requirements, sowing methods, and fertilizer selection.

1. Soil conditions

Broccoli prefers well-drained soil, does not require high pH, and a pH of about 6 is optimal. The soil area is large, the relatively loose environment is conducive to planting, the humidity of the lower soil layer must be ensured when planting, and the planting of broccoli seedlings on the nutrient-rich soil can make the roots of the broccoli seedlings quickly adsorb into the soil of the planting area, accelerate their growth rate, and ensure that they absorb more nutrients during the growth process to be more conducive to its growth and development.

2. Lighting requirements

Broccoli is a long-day plant, when planting broccoli, you must ensure that you get enough light, long day is conducive to photosynthesis and the accumulation of organic matter, but in the hot summer, you should also avoid excessive exposure to the sun for a long time, pay attention to proper shading and cooling.

, sowing method

The nutrient soil is placed in a planting box and soaked in water, and holes about 1 cm deep are pressed on the soil with a cola bottle cap, and the holes are spaced 30 cm apart. The seeds are then sown into small holes, with 2 to 3 seeds per small hole. After sowing, cover with a thin layer of soil, water and wait for germination, the suitable temperature for seed germination is about 25.

4. Fertilizer selection

One week after the emergence of seedlings, seedling fertilizer can be applied, after three weeks can be applied high-quality compound fertilizer, and then after the fifth week and the seventh week, the amount of high-quality compound fertilizer can be added, depending on the broccoli seedlings. At the same time, organic fertilizer and trace element fertilizer should be used in an appropriate amount, and the amount of fertilizer should also be reasonably controlled. Avoid excessive fertilization of broccoli, and at the same time, avoid insufficient fertilization affecting the growth of broccoli.

Seed selection and germination: Select high-quality broccoli seeds and soak them in warm water at 50 degrees for 25 minutes to sterilize. Sowing seedlings:

The seeds are drained and sown in soft, fertile and loose soil. Transplanting and planting: After the seedlings have grown to a height of 30 cm, they are transplanted in a fertile field to a depth of 3-4 cm.

1. Seed selection and germination cultivation

In the process of planting broccoli, it is necessary to choose seeds with good quality and no pests and diseases, and then put the seeds into warm water at about 50 degrees and soak them for 25 minutes to play the role of disinfection and sterilization.

2. Sow seeds and raise seedlings

Broccoli is suitable for growing in loose and breathable soil, you can choose fertile and moist, soft soil when planting, and apply well-rotted organic fertilizer as base fertilizer, and then drain the seeds, spread evenly in the soil, and cover a thin layer of soil.

3. Transplanting and colonization

After the broccoli seedlings grow to 30 cm, you can take transplanting and planting measures, select the seedlings with good growth in the field, no diseases and pests, dig out the soil, and plant them in the fertile field at a depth of 3-4 cm, and wait for the broccoli seedlings to survive, and keep the temperature between 15-20 degrees, which is conducive to the growth of the plant.
