Nowadays people are very much in pursuit of health, so some vegetable varieties with high nutritional value are more and more popular, such as cabbage, purple cabbage, broccoli and so on. Today we are going to learn about broccoli planting time and planting conditions.
First, planting time
It is understood that the planting time of broccoli is generally autumn, and then grow in winter, after the Spring Festival can be officially listed.
Second, the environmental requirements
Soil
Broccoli does not require strict conditions for planting soil, but it will have some impact if it is too fertile and too poor. The soil ph value is 6, and the sandy soil and loam with good fertilizer and water retention can be used.
2. Moisture
I like the amount of water needed, so even a short-term drought will affect its output.
3. Lighting
I like more sunshine during the broccoli planting process.
4. Temperature
The most suitable temperature for germination is 20 to 25 degrees Celsius, and the suitable temperature for seedling growth is 15 to 20 degrees. Broccoli has good heat and cold resistance.
Third, seedling technology
Variety selection
Broccoli belongs to vegetables that like cold, and has strong growth potential. The flower buds are dark green, the buds are less, the flower ball is round, the side buds are small, the buds are small, the flower balls are large, the disease resistance is heat-resistant, cold-resistant, and the adaptability is wide. Varieties, such as Japan's excellent, dragon green, landscape, other varieties of Yuguan, Oriental Emerald, Wanlv, Green Show, etc. or according to market demand to select all kinds of high-quality varieties, but must comply with national secondary seed standards before use .
2. Sowing time
The double-cover cultivation in autumn is planted in early July, and the winter greenhouse cultivation in the solar greenhouse is planted in late July to August. The early spring cultivation in the solar greenhouse is planted in early September to early October. The plastic greenhouses and small arch sheds are planted in early spring and planted in November. The plastic film cultivation was planted in January.
3. Seed treatment
1 soaking
Soak in the warm water of 33 ° C for 15 minutes, stir constantly, wait until the water temperature drops to 20 ° C, continue to soak for 4 hours with warm water, wash with clean water and then germination.
2 germination
The soaked seeds were wrapped in wet cotton gauze and germinated at a temperature of 30 °C. Wash once a day with water, and sow 60% of the seeds when they are white.
4. Daejeon nursery
1 seed bed selection
The broccoli seedling period is shorter, the seedbed is selected in the high ground, the irrigation and drainage is convenient, the soil is rich in organic matter, and there is no cruciferous vegetable or the former rice field in the past two years, and the seedbed is oriented to the north-south direction.
2 apply enough base fertilizer
15-20 days before sowing, deep turn, 7-10 days before sowing, apply 15 kg of ternary compound fertilizer per acre plus 5 kg of superphosphate or 2500 kg of decomposed manure and urine to ensure sufficient supply of nutrients in the seedling stage. Crush the land and make a sowing bed about 1.2 meters wide. The ratio of Putian is 1:20-30.
3 mixed medicine sowing
Before sowing, the seedling bed is poured once, and 1000 times of phoxim is applied to prevent underground pests. When planting, the treated seeds are mixed with the right amount of sand and evenly spread in the seedbed. After sowing, the shovel is used for suppression. Sprinkle a layer of medicinal soil mixed with 0.1% carbendazim and diclosan.
4 shade insulation
After the summer seedbed is covered with a layer of shade net, the small arch shed is set up, and then a layer of shade net is covered to carry out double-layer shading and moisturizing to cool the seedlings. In winter and spring, a layer of mulch and a shed film are used to carry out double-film covering and heat preservation.
5. Nutrient liquid nursery
Nutrient liquid nursery is a better breeding method at present. It has the characteristics of low cost, convenient management, high seedling rate and centralized seed supply, which is welcomed by production and processing enterprises.
1 matrix
25% vermiculite, 65% peat, and 10% perlite.
2 matrix stacking disinfection
After thoroughly mixing all the raw materials, use 50-100 times formalin (40% formaldehyde), spray evenly on the substrate, then cover with plastic film tightly, seal for 4-5 days, uncover the membrane and ventilate, and turn the nutrition The soil, the formaldehyde is volatilized out, can be used after 2 weeks, and the pH of the substrate needs to be adjusted to 6.5-7, the peracid is adjusted with lime, and the perbase can be neutralized with dilute hydrochloric acid.
3 sowing
Fill the tray with the substrate, pour the water, then use a special acupoint machine to dig the seeding hole, and use the seeder to sow the seed into the seeding hole to cover the substrate.
The prospects for broccoli planting have become more and more good in recent years. The number of people who want to plant broccoli is also higher than before. In summary, the broccoli cultivation points mentioned above can be seen when everyone is fine.
