How to grow broccoli

season

Broccoli can generally be planted in spring and autumn. In spring, it is generally cultivated in the middle and late January. The seedling time is about 50-60 days. Wait until late March, you can plant seedlings, then wait until late May you can receive broccoli, if planted in autumn, then start seedling in mid-early July, planting words will be in mid-August, wait until mid-late October can receive broccoli.

soil

Broccoli still has some requirements for the soil, generally to choose loose, fertile, breathable and have a good ability to retain fertilizer and water soil to plant, choose sandy soil is also possible.

moisture

Broccoli needs a lot of water during the whole growth process, especially during the vigorous growth of leaves and the formation of flower bulbs. Even if it is short-term drought, it will reduce the yield. Plenty of rain or excessive soil moisture at seedling stage is easy to cause black rot, black spot and other diseases. The soil moisture content in the field at the stage of flower bulb formation is about 70-80% to meet the needs of growth.

fertilization

Broccoli requires more nutrients and complete, generally mu of high-quality fertilizer 5000 kg, decomposed manure 500 to 1000 kg, calcium superphosphate 30 to 40 kg, plant ash 50 kg.

recovery

Broccoli is harvested when the bulb at the top of the plant is fully expanded and the bud has not yet opened. When the lateral bulb grows to a certain size and the bud has not yet opened, it can be harvested again. In this way, it is generally possible to harvest 2 to 3 times in succession.

Broccoli is not very difficult to raise plants, if you follow the above steps step by step to implement, you can certainly grow beautiful and healthy broccoli, if you like to eat broccoli very much, must learn how to raise it, because after learning its cultivation method, you can raise it yourself, so you don't have to worry about buying broccoli outside is not healthy.

When to plant broccoli broccoli

Broccoli is a biennial herb, native to the eastern Mediterranean coastal areas, China has a small number of cultivation, mainly for Western use. Broccoli is rich in nutrients, including protein, sugar, fat, vitamins and carotene. Its nutritional composition ranks first among similar vegetables and is known as the crown vegetable. Broccoli flower morphological characteristics, growth habits and common white cabbage (cabbage) is basically similar, cruciferous Brassica species, 1~2-year herbs.

I. Introduction to broccoli

Broccoli belongs to Cruciferae family and is another variety of cabbage. Originated in Italy, in recent years, China has a small number of cultivation, mainly for Western use. This dish is easy to plant and easy to plant. It is cultivated by stages and eaten all the year round. Broccoli is between cabbage and cauliflower. The top of the main stem forms green or purple hypertrophic flower balls. The small buds on the surface are obvious and loose, but not dense into balls to collect the tender stems of flower buds for consumption. Broccoli originated from the Mediterranean coast of Europe because of its rich nutrition and excellent taste.

Broccoli originated in Italy along the Mediterranean coast of Europe and was introduced into China at the end of the 19th century. Broccoli flower morphological characteristics, growth habits and common white cabbage (cabbage) is basically similar, cruciferous Brassica species, 1~2-year herbs. Strong growth, heat resistance and cold resistance are strong. Plant tall, according to different varieties of leaf growth about 20 out of flower stems, the top group of buds.

Broccoli may be the most significant is that it has anti-cancer effect, cauliflower contains more vitamin C, higher than Chinese cabbage, tomato, celery, especially in the prevention and treatment of stomach cancer, breast cancer effect is particularly good. In addition, broccoli also enhances the immune function of the body. The vitamin C content of cauliflower is extremely high, which is not only beneficial to human growth and development, but more importantly, it can improve the immune function of the human body, promote liver detoxification, enhance human constitution and increase disease resistance.

Second, when is broccoli sown?

The normal season of broccoli planting time is to start sowing in autumn, grow in winter, and be listed on the table normally after the Spring Festival. Flowers begin to bloom in spring and mature in April and May. Summer and autumn seedling: seedling in high temperature season in 8~10 months. At this time, the temperature is generally above 25℃, sometimes 30~35℃ high temperature, coupled with heavy rain, hail damage, so the use of shade net in the open field seedlings. Its seedling age is generally 35 - 40 days. Sowing or direct hole planting can be adopted. The average seedling period is about 30 days, and 80~90 days from planting to harvest. Winter sex is stronger, seedling stem diameter 10mm can accept the influence of low temperature, complete the vernalization process.

Broccoli is not very strict on the requirements of light, but in the process of growth like sufficient light, light enough plants grow strong, can form a strong vegetative body, conducive to photosynthesis and nutrient accumulation, and make the ball compact, bright green color quality is good, summer sunshine is too strong is not conducive to broccoli growth and development.

Broccoli requires more and more nutrients, but its roots are shallow. Therefore, it is required to plant in fertile soil, water and fertilizer conservation plots. Broccoli must be harvested at the right time. Harvest too early, bud is not fully developed, can not reach the standard of finished products; harvest late or in case of high temperature weather, will appear scattered flowers and may be yellow, should pay attention to water supply. If the quality deteriorates, it loses its commodity value.

Third, broccoli planting methods

Broccoli is not strict with soil conditions, but if it is too poor, the plant will develop poorly and the yield and quality will be low; and if the soil is too fertile, it will lead to loose buds and hollow flowers. Broccoli is suitable for planting in loam and sandy loam with good irrigation, deep ploughing layer, loose and fertile soil, strong water and soil conservation fertility. Belonging to vegetables that like cold, select varieties with strong plant growth potential, dark green flower buds, few scorched buds, round flower bulbs, few lateral buds, small buds, large flower bulbs, disease resistance and heat resistance, cold resistance and wide adaptability. Such as: Japan's excellent, dragon green, landscape, other varieties of jade crown, Oriental green treasure, million green, green show, etc. or according to market demand to select various high-quality varieties. However, it must meet the national second-class seed standards before it can be used.

Sowing: water the seedling bowl filled with soil thoroughly before sowing, and sow after 1 to 2 days. Varieties using imported or domestic seeds, artificial seed or mechanical sowing. Each bag of seeds is 10~ 15g, sown on 0.8~1 mu of land, and can breed 160 ~ 170,000 plants/mu. The size of the seedling bowl is 8 cm in diameter * 8 cm in height or 6 cm in diameter * 8 cm in height. Press a small nest in the middle of the seedling bowl with your fingers, and point one seed per small nest.

Dividing seedlings, generally about 15 days after sowing, when the seedlings grow to 4 leaves and one heart, start dividing seedlings. One day before dividing seedlings, first irrigate seedlings thoroughly, then transplant seedlings, cut roots and squat seedlings. Divide big seedlings and small seedlings, promote small seedlings and control big seedlings, so as to cultivate strong seedlings and neat seedlings, set up sunshade net to prevent sun and cool down after seedling division, and irrigate thoroughly at the same time. Generally, the seedlings grow in the greenhouse for 30~35 days, and the seedlings grow to 6 leaves and one heart, and begin to transplant. To ensure consistent seedling age, conducive to consistent harvest.

Weeding, generally take artificial weeding, no chemical weeding. Weed once before seedlings emerge. Then weed once when the seedling grows to one leaf, weed once before seedling division, or weed when the density of weeds reaches 3~5 plants per square meter.

Insecticides, spraying green pollution-free pesticides, generally designated pesticides. Common diseases and insect pests in seedling stage include damping-off disease, gray mold, diamondback moth, jumping and so on. In order to prevent the occurrence of diseases and insect pests, pesticides and fungicides are generally sprayed 2 to 3 times at the seedling stage, and spraying can be arranged 2 days before seedling division, 5 days after seedling delay, and 3 days before planting.

Finally, broccoli nutrients, not only high content, but also very comprehensive, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene, etc. In addition, broccoli mineral composition is more comprehensive than other vegetables, calcium, phosphorus, iron, potassium, zinc, manganese and other contents are very rich, much higher than the same cruciferous cabbage flowers. That's all for today's introduction to broccoli cultivation.
