Green and Efficient Production Technologies of Oenanthe decumbens in Summer

Abstract: In order to meet the market demand for Oenanthe decumbens in high temperature season and improve the annual production benefit, the research on green and efficient production technologies of Oenanthe decumbens in summer was conducted. The problems of rotting seed, floating plants, pesticide residue and no tender productions in the production process during high temperature season were solved. A complete green and efficient production technology system had been formed, which included breeding of Oenanthe decumbens, setting and fertilizing of Oenanthe decumbens pond, sowing time, treatment and sowing of Oenanthe decumbens, cutting and regeneration, management of water layer, formulated fertilization, green control of diseases and pests, harvest and marketing and so on. The yield was 2 000-3 000 kg per 667 m2, the output value was 20 000-45 000 yuan per 667 m2 and the economic benefit was 15 000-25 000 yuan per 667 m2, so the technological effects were significant.
