What are the seed planting methods of broccoli (also called broccoli)? What are the planting prospects? How much money can you earn per mu?

Broccoli, broccoli, commonly known as broccoli. It's a common vegetable. Commonly known as cauliflower, biennial herbs. It originated in Italy and has a wide range of branches in China. So do you know the seed planting methods of broccoli? What are the planting prospects? How much money can you earn per mu? According to a large broccoli grower in Jiangsu, he has an average yield of 3500-4000 kg per mu of broccoli, which can reach 2.4-3 yuan per kilogram. After deducting the production cost, one mu of broccoli can earn nearly 10,000 yuan.

I. seed planting methods of broccoli

1. Variety selection

Broccoli belongs to vegetables that like cold and cool. Choose varieties with strong plant growth, dark green buds, few burnt buds, round flower balls, few lateral buds, small buds, large flower heads, disease resistance and heat resistance, cold tolerance and wide adaptability. such as Japanese excellent, dragon green, landscape, other varieties such as Yuguan, Oriental Lubao, Wanlu, Lvxiu or according to market demand to select all kinds of high-quality varieties, but must meet the national second-class seed standards before use.

2. Sowing time

The double mulching cultivation in autumn was sown in early July, the overwintering cultivation in solar greenhouse was sown from late July to August, the early spring cultivation in solar greenhouse was sown from early September to early October, and the early spring cultivation in plastic greenhouse and small arch greenhouse was sown in November. Spring plastic film cultivation sowed in January.

3. Seed treatment

(1) seed: soak the seeds in 33 ℃ warm water for 15 minutes, stir continuously, stop when the water temperature drops to 20 ℃, continue soaking in warm water for 4 hours, rinse with clean water and then sprout.

(2) Bud: the soaked seeds were wrapped in wet cotton gauze and germinated at a temperature of 30 ℃. Rinse with clean water once a day and sow when 60% of the seeds are white.

4. Raising seedlings in the field

The main results are as follows: (1) bed selection: the seedling stage of broccoli is short, and the seedling bed is selected in the fields with high terrain, convenient drainage and irrigation, soil rich in organic matter, no cruciferous vegetables or rice in the past two years, and the direction of the seedling bed should be north-south.

(2) foot base fertilizer: turn deeply 15-20 days before sowing, 7-10 days before sowing, apply 15 kg of ternary compound fertilizer plus 5 kg of superphosphate per mu or pour 2500 kg of rotten human feces and urine to ensure the full supply of nutrients at seedling stage, dig and rake the land, and make a seeding bed about 1.2m wide, the ratio of seedling field is 1:20-30.

(3) Drug sowing: before sowing, the seedling bed was watered once, and 1000 times phoxim and other chemicals were applied to prevent underground pests. When sowing, mix the treated seeds with appropriate amount of sand and spread them evenly in the seedbed, and suppress them with a shovel after sowing. Sprinkle a layer of medicinal soil mixed with 0.1% carbendazim and dimethazone.

(4) Sun insulation: after laying a layer of sunshade net in summer, set up a small arch shed, and then cover a layer of sunshade net, carry out double-layer sunshade, moisturizing and cooling seedlings, and use a layer of plastic film and a layer of greenhouse film in winter and spring to cover and raise seedlings.

5. Raising seedlings with nutrient solution

Raising seedlings with nutrient solution is a better way of raising seedlings at present, which is welcomed by production and processing enterprises because of its low cost, convenient management, high seedling rate, centralized seedling supply and so on.

(1) quality: vermiculite 25%, peat 65%, perlite 10%.

(2) Mass stack disinfection: after fully mixing all raw materials, use 50-100x formalin (40% formaldehyde), spray evenly on the substrate, then cover tightly with plastic film, after sealing for 4-5 days, uncover the film for ventilation, turn over the nutrient soil, so that formaldehyde can be volatilized, and can be used after 2 weeks, and need to adjust the ph of the matrix to 6.5-7, overacid can be adjusted with lime, peralkali can be neutralized with dilute hydrochloric acid.

(3) species: fill the hole plate with matrix and pour water thoroughly, then dig the sowing hole with a special burrowing machine, sow the seeds into the sowing hole with the seeder and cover the substrate.

2. What are the planting prospects of broccoli?

Tang Xiaowei, a researcher at the National vegetable Engineering Research Center, pointed out: broccoli is the best vegetable. It has been scientifically proved that the nutrients in broccoli are not only high, but also very comprehensive. It mainly includes protein, carbohydrates, fats, minerals, vitamin C and carotene. According to analysis, every 100 grams of fresh broccoli bulbs contain 3.5-4.5 grams of protein, three times that of cauliflower and four times that of tomatoes, and the content of vitamin C is higher than that of chili peppers. In addition, the mineral composition of broccoli is more comprehensive than other vegetables, and the contents of calcium, phosphorus, iron, potassium, zinc and manganese are very rich.

The anticancer effect of broccoli is recognized all over the world. in addition, broccoli is also rich in ascorbic acid to enhance the detoxification ability of the liver, and the flavonoids can regulate and prevent hypertension and heart disease. At the same time, broccoli is a high-fiber vegetable, which can effectively reduce the gastrointestinal absorption of glucose, and then reduce blood sugar, effectively control the condition of diabetes.

Broccoli is a kind of vegetable with rich nutrition and unique flavor, which is deeply loved by consumers all over the world. it is in great demand in Europe, America and Japan. The annual sales volume in Japan alone reaches 300000 tons. The future of the market is very broad.

With the rapid development of China's economy and the improvement of people's living standards, it is imperative to improve the quality of life of residents, and the demand for broccoli in the domestic market is also increasingly strong, especially in big cities such as Shanghai and Beijing.

In recent years, 70% of the country's exports of Japanese broccoli are exported by Taizhou. Although the cultivation of broccoli in China has been expanded, there are few bases that integrate large-scale production, processing and export. Therefore, relying on the advantages of natural resources and labor force in our county, there are broad prospects for establishing a production base of 60,000 mu of efficient ecological broccoli export vegetables and agricultural leading enterprises with an annual processing capacity of 10,000 tons. Broccoli deep processing project implements cold treatment, dehydration, vacuum packaging and other methods to process the flower buds of broccoli into high-quality products and push them to domestic and foreign markets; the processing of vegetable leaves, stems and other by-products to meet the needs of different markets; the project through processing agricultural leading enterprises to implement integrated production, processing and marketing to promote industrial development, so as to drive farmers to a well-off society.
