Broccoli farming requirements, how to grow broccoli

1. Substrate selection: broccoli will grow well in loose, breathable and well-drained acidic soil, and can be planted after mixing bean dregs, animal manure or humus with soil, or adding nitrogen fertilizer to increase soil fertility.

2. Water management: Growing broccoli requires keeping the soil moist but not waterlogged, and it is recommended to water it every 5 to 6 days. When it is dry and does not rain, increase the frequency of watering depending on the situation to keep the soil moist.

When the rain is heavy, drain the water frequently to prevent broccoli from getting sick.

3. Nutrient management: Bika water-soluble fertilizer can be applied two to three times at the rosette stage, phosphorus fertilizer and nitrogen fertilizer need to be applied during the flower bulb expansion stage, and foliar fertilizer can be sprayed with boron, molybdenum, magnesium and other trace elements.

4. Light management: broccoli likes to grow in sunny places, and sufficient light can promote the photosynthesis of broccoli, produce sufficient nutrients for the plant, and at the same time, make the surface of broccoli more green, more beautiful and beautiful. In summer, the sun is strong, so take good shade measures.

The normal sowing time for broccoli is to start sowing in the fall, grow in the winter, and then reach the table normally after the Spring Festival. Flowering begins in spring until the seeds reach maturity in April and May.

Summer and autumn seedlings: Seedlings are raised during the high temperature season from August to October. At this time, the temperature is generally above 25, sometimes sometimes at a high temperature of 30-35, coupled with heavy rain, hail damage, so use shade nets in open fields to raise seedlings.

The seedling age is generally 35-40 days. Seeding or direct cutting can be used. From planting to harvesting 80-90 days, the average seedling period is about 30 days.

It is slightly stronger in winter, and the stem diameter of the seedling is 10mm, which is affected by low temperature and completes the vernalization process.

Broccoli planting precautions.

Broccoli does not have very strict requirements for light, but it likes sufficient light during growth, and in the case of sufficient light, the plant will grow vigorously, which can form a strong plant body, which is conducive to photosynthesis and nutrient accumulation, and makes the flower bulbs dense. In midsummer, it is dense, bright green and of good quality, and too much sunlight is not conducive to the growth and development of broccoli.

Broccoli growing environment.

1. Light: broccoli does not have very strict requirements for light, but it likes sufficient light during the growth process, and in the case of sufficient light, the plant will grow vigorously, which can form a strong plant body, which is conducive to photosynthesis and nutrient accumulation, and makes the flower bulb dense. In midsummer, it is dense, bright green and of good quality, and too much sunlight is not conducive to the growth and development of broccoli.

2.Temperature: broccoli in the range of 5-20, the higher the temperature, the faster the growth and development, the best germination temperature is 20-25, the growth temperature of the seedling stage is 15-20, with strong cold tolerance and heat resistance, the suitable temperature for the growth of the rose festival is 20-22, the suitable temperature for the development of the flower bulb is 15-18, when the temperature is higher than 25, the quality of the flower bulb is easy to deteriorate, but as long as it is not frozen, the flower bulb is 5.

It can grow slowly even at lower temperatures.

3.Moisture: Broccoli needs a lot of water throughout the growth process, especially during vigorous leaf growth and flower bulb formation, it cannot lack water, even if it is a short-term drought, it will reduce the yield, rainy seedlings or too much moisture in the soil can easily cause diseases such as black rot, black spot.

The soil moisture in the flower bulb formation field accounts for about 70-80 percent of the water holding capacity in the field to meet the growth demand.

4.Soil: Broccoli does not have strict requirements for soil conditions, but if it is too poor, the plant will not grow well and the yield and quality will be reduced.

However, too much fertile soil can lead to loose buds and hollow flower stands. Suitable for good irrigation and drainage, deep tillage and loose soil. It is planted on fertile, water-retaining and labor-intensive loam and sandy loam soils with a soil pH range of, but preferably 6.

When planting broccoli, first put the selected excellent seeds in 50 warm water to soak and promote germination, select the cultivation soil with good air permeability, ensure that the soil is fertile and moist and soft state is the best, the thickness of the soil covering after planting is 3 4 cm, and the seedlings can be watered more slowly before they survive.

Broccoli cultivation method:

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.

3. 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.

Once broccoli is sown, it usually germinates within a week. When the broccoli has grown about 5 leaves, the seedlings are thinned, leaving one healthy and strong seedling in each hole according to the growth potential, and the rest are pulled out.

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. Organic fertilizer and trace element fertilizer should be used in moderation at the same time.

In terms of fertilizer amount, it should also be reasonably controlled. Avoid excessive fertilization of broccoli, and at the same time, avoid insufficient fertilization affecting the growth of broccoli.

When planting broccoli, first put the selected excellent seeds in 50 warm water to soak and promote germination, select the cultivation soil with good air permeability, ensure that the soil is fertile and moist and soft state is the best, the thickness of the soil covering after planting is 3 4 cm, and the seedlings can be watered more slowly before they survive.

The first step of broccoli germination treatment is to select better seeds, which can improve the quality of crops, soak the seeds in 50 warm water for 25 minutes before sowing, so as to kill the pathogens that invade the seeds, and also make the seeds soft and have strong water absorption ability, so as to improve the survival rate of seeds.

Substrate preparation is the basic requirement of broccoli planting technology, the substrate preparation of broccoli is very critical, first of all, we must select the cultivation soil with good air permeability, but also ensure that the soil is fertile and the best state of moist and soft, and finally add an appropriate amount of well-rotted organic fertilizer, buried in the soil layer.

When planting broccoli, try to bring more soil, and do not hurt the root system, shorten the seedling period, the planting depth is grasped in the distance from the covering soil to the leaf is 3 4 cm is the most suitable, the seedlings can be watered more before surviving, and the seedlings grow to 25 30cm when transplanting.

After the seedlings of broccoli survive, the temperature around it should be kept between 15 and 20, the higher the temperature, the faster the broccoli grows relatively fast, but not higher than 35, greenhouse seedlings, after transplanting to strengthen water and fertilizer management, can be used in the high temperature season.

Broccoli should be applied 1:5 of decaying manure water once a week before the seedlings survive, in order to promote the seedlings to absorb nutrients, improve the survival rate, when 8 10 leaves grow, can be topdressed urea once, broccoli growth period to water more, do not cause water accumulation.

When planting broccoli, it is necessary to provide it with fertile and breathable acidic soil, at the same time to add some basal fertilizer to the soil, also need to water the plants every 5 to 6 days, and pay attention to drainage measures, but also need to provide sufficient light conditions for broccoli to ensure that they photosynthesize and store nutrients for the growth of plants.

1. Soil environment

When planting broccoli, it is necessary to provide fertile, breathable, well-drained acidic soil, and at the same time add some base fertilizer to the soil to ensure the fertility of the soil, and also need to loosen the soil and weed regularly, which is conducive to the loosening of the soil and promotes the absorption of nutrients by plants.

2. Moisture control

Broccoli needs a lot of water during the growth process, and it is necessary to water the broccoli every 5 to 6 days during the planting process to ensure that the water content in the soil is controlled at about 75% to avoid excessive soil moisture content leading to rot at the roots of the plant.

3. Light management

Broccoli loves light, needs sufficient light for photosynthesis, stores nutrients for its growth, when planting broccoli, it needs to be planted in a sunny place to ensure that the plant has sufficient nutrients in the growth process, and enough light, it can also make the surface of the old orange broccoli more green.

4. Apply fertilizer

Broccoli likes fertilizer, in its growth period needs a lot of nutrients to promote the expansion of flower bulbs, when planting broccoli, it needs to provide sufficient fertilizer to meet the growth of plants, in the broccoli growing season, it needs to be sprayed with some foliar fertilizer, which can promote the growth of plant flowers and leaves, so that broccoli has better quality.
