First, use fine varieties. Summer season cultivation of parsley, should choose good heat resistance, resistance to disease and strong resistance to a large variety of coriander varieties. Second, timely sowing. In general, parsley is sown in early July, which can yield higher yields and higher market prices. Seeding is generally suitable for sowing, if the supply of fast-growing seedlings should be highly dense planting, sowing rate of about 8 ~ 10kg per 667 square meters. After sowing water, cover 1cm thick straw to promote seedling emergence. Third, field management. First, keep the soil moist before emergence. The second is early management. Generally should be in the 7 days after the emergence of seedlings between the seedlings, two true leaves when the Dingmiao, seedling distance 3 ~ 4cm. In general, about 1 day, the water is poured 1 time. When the seedling height is 3cm, the first time the fertilizer is chased, and the topdressing urea is 8 to 10kg and the boron fertilizer is 250g per mu. After one time of water, one-time foliar dressing was performed with 300 times of Zhengfeng Ecological Paste plus 0.3% urea solution. Add appropriate amount of potassium dihydrogen phosphate at the later stage of foliar application. Third, it is advisable to spray a solution of Nine Oxygen of 25mg/kg in the first half of harvest to promote the elongation of the petiole, increase the number of leaves, and increase the yield. Fourth, scientifically control pests and diseases. Because parsley has a pungent scent, very few insect pests occur. Diseases mainly include seedling stage damping-off disease, adult stage virus disease, anthrax and spot blight. Five days after emergence, the non-pollution fungicide was sprayed with 3% oxygenated oxygen 800 times for one time, and then sprayed once every 7 days with 600 times of polyoxygenation solution for a total of 2 or 3 times to prevent the knock-out disease. Occurrence can prevent anthrax and spot blight. If viral disease occurs, it can be controlled by 800 times potassium permanganate solution or virus K1000 solution.
