When to plant broccoli
Today, I will introduce to you when to plant broccoli and the content about the planting time and methods of green plants and flowers, which is a very good knowledge of experience. It is recommended to collect it!
Broccoli is a biennial plant of the brassica oleracea var. acephala group, a variety of cabbage. It is a vegetable. It is a variant of cabbage, the same as headed cabbage. Broccoli is also known as green cauliflower, purple cauliflower, tender stem cauliflower, Italian rapini, and stem cauliflower. It is an autumn and winter vegetable that prefers warm and humid climates, has a wide adaptability, is easy to cultivate, and has high value. How to plant broccoli?
I. Broccoli Planting Time
In southern regions, it can be planted all year round, but it is mostly cultivated in autumn and winter. In warm areas, autumn cauliflower is sown from mid-June to mid-July, in mild areas from early June to early July, and in cool areas from mid-May to early June. In warm areas, winter cauliflower is sown from mid-August to early September, in mild areas from mid-July to mid-August, and in cool areas from late June to mid-July.
II. Broccoli Planting Methods
1. Variety Selection: Broccoli is adaptable and can be planted all year round, but different varieties should be selected for different seasons. In spring, it is suitable to plant varieties like Black Green, Liu Ling Qing, and Bao Guan. In summer, it is suitable to plant varieties like Zheng Lan Shui Zhong, Xia Lü, Lü Wang, and Lü Fang. In autumn, it is suitable to plant varieties like Lü Ling, Qing Nong 50 Days, and Wen Xing Broccoli. For overwintering cultivation, it is advisable to choose mid to late maturing varieties.
2. Seedling Raising: Choose a fertile, loose, well-drained, cool, and ventilated area for the seedbed. Before sowing, deeply turn the bed soil, apply decomposed manure and a small amount of compound fertilizer, mix it evenly with the bed soil, and sprinkle a thick layer of livestock manure water. After 2-3 days, loosen the soil, wet the bed, and sow about 10 grams of seeds per square meter. After sowing, cover with about 1 centimeter of fine soil, cover with shade netting, water once more, and then water as needed to keep the soil moist. After 3-4 days, most seeds germinate, practice semi-shaded covering to prevent direct sunlight and rain冲击. As the seedlings grow, gradually uncover the shade netting.
3. Seedling Management: Timely thinning and transplanting are key to growing strong seedlings. When the seedlings emerge 10 days after sowing, thin the overgrown ones. When the seedlings are a bit larger, thin them again to maintain a distance of 3-5 centimeters between plants. When the seedlings emerge 20 days after sowing, the original nutrient area is limited, so a transplanting is necessary. The requirements for the transplanting bed are the same as for the播种 bed, with a row spacing of 7-10 centimeters. Cover with shade netting to provide shade, water while transplanting. Keep the bed soil moist after transplanting. Broccoli does not require much fertilizer in the seedling stage, just pay attention to watering to prevent drought. In the middle and late stages of seedling growth, if there is a fertilizer deficiency, you can apply decomposed livestock manure water or a 0.2% urea or compound fertilizer solution 1-2 times to make the broccoli seedlings grow strong.
4. Field Preparation and Fertilization: Choose a fertile, loose plot of land, deeply plow and level it, and create narrow high ridges 1 meter wide or wide high ridges 2 meters wide, with 2 or 4 rows per ridge and a hole spacing of 40-45 centimeters for applying ground fertilizer. Apply 3000 kilograms of decomposed manure and 20 kilograms of compound fertilizer per mu.
5. Transplanting: About 30 days after sowing, when the seedlings have 5-6 true leaves, the stem is 0.5 centimeters thick, and the plant height is 12-15 centimeters, it is suitable for field transplantation. If the seedlings are too old, the root damage during transplanting is too severe, and it is difficult to transplant. If the seedlings are too small, they will be weak after transplanting. Therefore, in addition to paying attention to strong seedling cultivation and mastering the seedling age standard, it is also necessary to choose overcast days or before and after rain for transplanting. Water the seedbed thoroughly before transplanting, and after about an hour, pull the seedlings to ensure they bring more soil and less root damage.
6. Field Management:
Broccoli prefers moisture and requires a lot of water and fertilizer to obtain high yield and quality inflorescences. Therefore, it is necessary to apply 1-2 times of clear manure water after transplanting to ensure the plant has a strong leaf cluster, especially after entering the rosette stage, when the plant grows vigorously and requires more fertilizer and water. You can add 50-100 grams of urea and compound fertilizer to each load of livestock manure water and apply it 3 times. Broccoli likes water but is afraid of waterlogging, so it is necessary to drain after rain and water during dry weather. Apply heavy fertilizer during the budding stage to promote the development of the inflorescence and increase yield.
Bundling the leaves is an important measure to ensure the quality of broccoli. When the inflorescence first appears, bring the large leaves on the outside of the inflorescence inward to wrap the inflorescence and tie it with straw.
7. Harvesting: The green, flat spherical inflorescence cluster at the top of the main stem of broccoli is compact at first and then gradually becomes loose, but at this time the inflorescence has not opened. Harvesting at this time ensures quality. Harvesting too late not only reduces the quality of the inflorescence but also affects the growth of lateral inflorescences. After harvesting the main inflorescence, the axillary buds on the main stem will grow into lateral branches, and the top of the lateral branches will also produce inflorescence clusters. Harvest them when they reach 20-25 centimeters in length, which can be done 2-3 times. After each harvest, apply a thin layer of fertilizer to promote the germination and growth of the lateral inflorescences.
The above introduction about when to plant broccoli and its planting time and methods is hoped to be liked by everyone!
