First, choose the best species. In the production of spring production, we should select fine varieties with good precociousness, high yield, excellent quality, and wide adaptability, such as imported Taiwan pine flower cauliflower.
Second, timely nursery. Planted in spring in our province, generally sowing in late February-early March, using greenhouses or improved cold shelters and other protective ground facilities nursery, in late March to early April mulching film planting, in early June can be harvested listed.
Third, soil preparation and fertilization. The demand for fertilizers is great for the broccoli, especially phosphorus, potash and boron, molybdenum and other micronutrients. Before the site preparation, 5000 kg of manure was cooked, 50 kg of high-phosphorus high-potassium compound fertilizer, and 1 kg of borax were uniformly spread on the surface of the crop and the land was ploughed.
Fourth, timely planting. Choose sunny and windless morning planting, with a row spacing of 60 cm, a plant spacing of about 50 cm, and a planting of 2000-2500 plants. Immediately after planting, the planting water shall be planted, the cover film shall be warmed and protected, and the seedling shall be promoted.
Fifth, field management. The soil where the broccoli is grown is neither too wet nor too dry. Keep the soil moist and loose. During the drought, horses should be irrigated and flooding should be prohibited; timely drainage after heavy rains can prevent the long-term water accumulation in the fields from causing roots. The demand for fertilizer during the bulbous expansion period is relatively large. According to the growing situation in the field, the application of compound fertilizer with nitrogen and potash fertilizer or deep ditching for 2-3 times, each time about 20 kg per mu, can promote bulb enlargement and Growth can increase production. The foliar spraying of functional foliar fertilizers and micronutrient supplementation can improve the quality and increase the effect of commercial products. In cultivating soil, before culturing till mulching, usually cultivating 2-3 times, the cultivator can prevent soil hardening from removing weeds. Combining cultivating soil with cultivators can promote the emergence of adventitious roots in the base, foster strong roots, promote rooting, prevent plant lodging, and perseverance in improving yield and quality.
Six, control pests. The pests that are harmful to the broccoli mainly include aphids, diamondback moths, leaf miners, caterpillars, and cabbage caterpillars. The plant protection policy of “prevention-oriented, comprehensive prevention and control†should be implemented in production, priority should be given to agricultural control, physical control, biological control, scientific and coordinated use of chemical control, strict control of the number of medications, compliance with safety intervals, and control of pesticide residues. Within the national standards for green food, safety, quality, and harmlessness are achieved. In the production of yellow plate can be used to kill, spray high efficiency and low toxicity pesticides and other methods combined.
Seventh, leaves protect flowers. In contrast to the traditional Huacai flower bulb care, the cauliflower is mostly used to protect the flowers without the use of folding leaves. When the flower ball grows to the size of a fist, 4-5 alternate leaves close to the flower ball are pulled together without breaking, and 1-2 2-3 mm thick, 7-10 cm long bamboo sticks are used. As a fixed connection, a small grass pole or a small firewood pole, a punctured and mutually overlapping leaf tip is serially fixed at a main vein, and a stringed and fixed blade is bundled in a lantern shape to cover the entire flower bulb so that the flower bulb can be subsequently grown. During the process, it is protected from direct sunlight and leaves enough space for development. The stricter the shade protection, the tighter the leaves and the flowers, can completely avoid the sunlight from reaching the flower balls. Even in the midsummer environment, the whole flower ball can still be kept clean and fresh.
Eight, timely harvest. When the diameter of the flower ball is fully enlarged, generally 30-40 cm, it can be harvested. The base retains 2-3 pieces of leaflets, which is conducive to protecting the flower balls and ensuring that the nutrients are not lost. Due to the crisp and juicy water of the cauliflower ball, it is vulnerable to mechanical damage during storage and transportation. A mesh bag should be put on the flower ball to prevent crush injury and it can be traded after being packed.
