Green cauliflower efficient cultivation
The green cauliflower, also called broccoli and broccoli, is eaten with its emerald green flower balls, which are made of saplings and flower buds. It is not only tender, delicious, nutritious, but also adaptable and easy to cultivate. There are promising nutrition and health-care high-grade vegetables. Its main cultivation techniques are: 1. Cultivation season Green broccoli can be cultivated in spring and autumn. Spring cultivation is more than Yangshuo nursery in the middle and late January. The nursery period is 50 to 60 days. The planting will take place in the middle and late March. The harvest will begin in the middle and late May. The autumn crop will be planted in the middle and early July, and will be planted in the middle and early August. Mid-to-late harvest. 2. Soil preparation, fertilization, and colonization of green cauliflower grow strong, require large amounts of fertilizer, must be combined with site preparation Shizu base fertilizer; general Mushi quality circle fertilizer 5000 kilograms, decomposed manure dry 500 to 1000 kilograms, superphosphate 30 to 40 kilograms, plant ash 50 kilograms. After applying basal fertilization, plough deep and plow it, and then level it to make it 1.3 to 1.5 meters wide. When the green cauliflower seedlings grow to 5 to 6 leaves, the plants are planted. Generally, each row is planted with 2 rows and the plant spacing is 30-40 cm. The planting density is about 2500 plants per mu; the early-maturing varieties can be planted densely to about 3,000 plants per mu. . 3. Fertilizer management Green cauliflower like fertilizer water, timely stage fertilizer, watering is the key to high quality, high yield. The type of topdressing fertilizer is mainly nitrogen fertilizer, and it enters into the formation period of flower bulbs. Phosphorus and potassium fertilizers are added appropriately to promote the rapid growth of flower bulbs. The florets and corms of broccoli flowers are harvested several times and harvested in time after each harvest. To promote lateral flower bulb growth. The cauliflower needs a large amount of water, and it should be watered in a timely manner during the rosette stage and the formation of the flower bulb to keep the soil moist. In rainy areas or seasons, the drainage should be promptly prevented to prevent water from picking up roots. 4. The harvested green cauliflower at the top of the plant is fully swollen and harvested when the buds are not yet open; it is easy to harvest the ball and flowering at late harvest. When harvesting, cut off the flower bulb with a flower stem about 10 cm below. After the bulb was harvested, the axillary buds of the plants germinated, and the lateral branches quickly emerged. The flower buds were formed on the top of the lateral branches, that is, the lateral flower bulbs. When the lateral flower bulbs grew to a certain size and the buds were not yet open, they could be harvested again. . In this way, it can generally be harvested 2 to 3 times.
