Non-polluted vegetables are vegetables that are not contaminated with pesticides and other pollutants. Vegetables are indispensable in people's lives, so pollution-free and safe vegetables are of great significance to people's health. The following small series talk about the pollution-free broccoli cultivation techniques. 1. Variety selection and production season arrangement 1.1 autumn and winter broccoli Variety: excellent, Yanxiu, super show and so on. Sowing: Early and late broccoli sowing in early autumn is generally in late July, early maturing in early August, mid-maturing in mid-August, late maturing in mid-September. Seedling: seedlings (128 holes) seedlings, leaf age 4.0~5.0 leaves, age 28-35 days. Seedlings 4~5 leaves can be transplanted and planted. The seedling bed is watered one day before the seedlings, which is good for pulling soil and pulling the seedlings and spraying with foliar fertilizer. Seedling requirements: The plants are thick, the leaves are thick, and the leaves are green. The roots are developed and free from pests and diseases. 1.2 Spring Broccoli Variety: Excellent Seedling: Use a tray (128 holes). 6~ 7 leaves can be transplanted. The seedlings require plants to be thick, the leaves are thick, the leaves are green, and the roots are developed without pests and diseases. 2. Site preparation and colonization 1 Soil preparation fertilization: Spring broccoli, before the rotation of the field, 1000 kg of decomposed organic fertilizer, 50 kg of superphosphate, 50 kg of potassium fertilizer, 1.5 kg of boron fertilizer (basic application type); 30~45 ml+10%. 2 Reasonable planting: The density is 3000~3300 per mu. 3. Pest control 1 black rot, soft rot: after transplanting to live with 80% must-have 600 times or love seedlings 700 times spray. Control 1 time for 3 to 3 times every 7 to 10 days. Stop taking the medicine after the ball is finished. 2 Plutella xylostella, Pieris rapae: In the period from September to November, the number of insects per plant is 1~2 drugs (the specific time is determined by the measurement report). Use 5% card to kill 1200 times (safety interval 10 days) or 5% taibao 1200 times (safety interval 10 days) or 1% Jiawei salt 500 times (safe interval 10 days) spray, add 99% green Ying 400 times spray. 3 Locust: Colonization ~ In November, when the plant damage rate is more than 10%, the drug is used for prevention and treatment. Use 70% Emerald WDG 15000 times (safety interval 10 days) or 10% imidacloprid 375 times (safety interval 10 days), plus 99% green Ying 400 times spray. 4, timely harvest Timely harvest: According to the requirements of the merchants, the diameter of the fresh-keeping ball is 10~15 cm, and the other diameter is 10-35 cm. The edge of the flower ball does not break. Harvesting method: harvesting with stainless steel knives, carrying out plastic baskets to prevent damage; timely delivery after harvesting to prevent water loss. And sent to the quality inspection department for testing and sale. Qingyuan and compost: After harvesting, the leaves, roots and weeds in the field are removed in time, and harmlessly treated and crushed into feed. The above is the pollution-free broccoli cultivation technology, broccoli as an annual supply of vegetables, the market potential is huge, coupled with the use of pollution-free technology cultivation, the prospects are better.
