Second, the site of fertilization to select convenient drainage, soil loose and fertile land, the front crops after the harvest in depth 20-25 cm in depth, drying for 15 days. In order to facilitate the use of the sunshade net, a deep groove sorghum having a width of 120 cm, a height of 20 cm, and a groove width of 30 cm is formed. Coriander has a short growth period, combined with land preparation, 3,500 kg of manure and per mu of manure per mu, 150 kg of cake fertilizer, and 50 kg of calcium, magnesium and phosphate fertilizers. It is necessary to finely level the topsoil of the clams to facilitate the emergence of seedlings.
Third, when the cultivation of summer and autumn anti-season cultivation of coriander, generally cultivated from mid-May to early July, the amount of seed per acre is 1 kg, which can achieve higher output value and higher prices. Cover the 1-2 cm when the soil moisture is suitable and spread evenly. Cover the grass to protect the tide and promote the seedlings, and remove them after 5-7 days, during which time to keep the soil moisture.
Fourth, the field management summer and autumn gas is getting higher, will affect the growth of coriander, therefore, after the grasshopper is removed, the sunshade net is covered in time. The sunshade net should adopt the method of daylight cover and nighttime exposure to enhance ventilation to prevent the seedlings from becoming slender and causing disease. Because of the short-term growth of coriander, it is advisable to weed early, early seedlings, and early-seeking quick-acting nitrogen fertilizer.
Generally, the seedlings should be carried out about 7 days after the seedlings, and the seedlings should be fixed when the two leaves are true. The seedlings are 2-3 cm away. Generally, water is poured once every 8 days, and when the seedling height is 3 cm, the top dressing is started, and 10-15 kg of urea and 250 g of boron fertilizer are applied per mu. In the future, carbon ammonia or urea should be applied 2-4 times in combination with the water-spraying period. When applying the foliar fertilizer in the later stage, an appropriate amount of potassium dihydrogen phosphate should be added to promote the growth of the leaves.
V. Pest Control The pest control of pollution-free coriander should be based on the principle of prevention and treatment, and a combination of various control methods to control pests and diseases to a minimum.
1. Agricultural control is based on the strong disease resistance, and the rotation is carried out to prevent rotation. Timely eradication of diseased leaves in the field, reducing the timing of infection. Strengthen fertilizer and water treatment to improve the disease resistance of plants.
2. Physical and biological control applications such as frequency-vibration insecticidal lamps, sexual attractants, Bt powders and other physical control skills.
3. Chemical control diseases mainly include seedling stage collapse disease, adult stage virus disease, anthracnose disease and spot blotch. 5 days after emergence, spray once with 800 times of non-polluting fungicide 3% polyoxygenate. In the future, spray 100 times of polyoxygenate every 7 days for a total of 2-3 times to prevent smashing. Anthrax and spot blotch. To prevent and cure viral diseases, insect nets can be used to prevent the spread of aphids; use shading to prevent high temperature and drought, reduce the incidence of aphids; and use 20% imidacloprid wettable powder 20 g plus 50 kg of foliar spray to completely control aphids, Prevent the onset of viral diseases. Liriomyza sativae is sprayed with 1% avermectin 1500 times solution. Disclaimer: Some articles on this website are transferred from the Internet.
