A kind of one-time harvest cultivation techniques for winter vegetables
Winter vegetables, also known as horseshoe vegetables, slippery vegetables, etc., seedlings and tender stems and leaves are important parts for people to eat. Its stems and leaves are silky, clear and fragrant, and nutritious. It can be used as a seasoning for soups and shabu-shabus. Dong Han Cai was originally a green leafy vegetable that can be harvested for a long time and has a long supply period. According to the author's introduction and test marketing observation, the quality of winter cold vegetables is not good in summer and early autumn, and consumers rarely care about it. The method of autumn sowing and one-time harvest cultivation is not only easy to plant, but also has a smooth market and a considerable economic benefit. The one-time harvest cultivation techniques for winter vegetables are: 1, grasp the season: cold and hi-cold winter like the weather humid climate, growth temperature is suitable for 15-20 °C, Shandong, the appropriate sowing time in autumn is from September to early October. Autumn sowing winter vegetables should use strong growth potential, short petiole, leaf hypertrophy, wrinkled leaves, cold resistance, good purple stem winter vegetables. 2, fine sowing: planting winter vegetables should be selected loose fertile, well-drained, non-continuous cultivation of fertile vegetable gardens, combined with cultivator, full base fertilizer and soil pesticides, the whole growth of about 15 meters, 1.5 meters wide flat rake. Before sowing, the water was poured into the bottom water. After the water was soaked, the seeds were evenly spread on the surface of the lotus root, and then about 0.8 cm thick fine soil was covered. The sowing volume per acre is 1-1.2 kg. About 5 days after sowing, they can emerge. 2-3 true leaves time seedlings, 4-5 true leaves when the Dingmiao, seedlings from 13-15 cm. 3, increase fertilizer retention of water: winter cold vegetables grow fast, consume water, nutrients more, to ensure the supply of fertilizer during growth. Winter vegetables require large amounts of fertilizer and have strong resistance to fertilizer. After about 10 days of settling, they should apply about 10 kg of urea or 15 kg of high-nitrogenous water-soluble ternary compound fertilizer per acre with water. In general, it should be kept moist without water. 4, disease prevention and pest control: The author found in the trial species, winter cold vegetables in the growth process, only anthrax, root rot and Spodoptera litura, aphids harm. Anthrax can be controlled by 70% thiophanate-methyl WP 800 times or 75% chlorothalonil wettable powder 600 times alternately for 7-10 days. In the initial stage of root rot disease, the diseased plants can be watered on a sunny day with 72% of Nonglilai WP 700-800 times solution or 40% root rot Ning 1000 times solution. For Spodoptera litura can be used 15% DuPont hit the suspension agent 3500-4500 times or 10% divided by the cream of 1500-2000 times liquid spray. For aphids 10% imidacloprid WP 3000-4000 can be used to kill. 5, timely harvest: autumn sowing winter vegetables 50-60 days after sowing, seedling height 18-20 cm when the whole plant can be harvested, tied to the market. Yield per mu 1500-2000 kg. Winter cold vegetables not only do not wither under light frost, but also can further improve the quality through the role of low-temperature frost, which is conducive to delaying harvest.
