席草在我国主要分布在长江中下游地区。种席草的经济效益较高,一般亩产600～800公斤,产值300～500元,高的达900元以上。草后稻亩产可收400～450公斤。一、气候、土壤条件席草是长日照作物,耐低温性能较强。在全年日平均气温12～16℃,1～2月极端低温-10～-12℃,3～7月中旬积温1800℃以上,日照700小时左右,年降水量1000～1400毫米的地区均可栽培。席草分蘖的生物学起点温度为3℃,冬前日平均温度降到5℃以 Grass seats in our country mainly in the middle and lower reaches of the Yangtze River. The matted grass has higher economic benefits, with a yield of 600 to 800 kg per mu and a production value of 300 to 500 yuan, with a high of 900 yuan or more. After the grass yield per mu can receive 400 to 450 kg. First, the climate, soil conditions Grass is a long sunshine crops, low temperature performance. In the annual average temperature of 12 ~ 16 ℃, 1 to 2 months of extreme low temperature - 10 ~ - 12 ℃, 3 ~ mid July 1800 ℃ above temperature, 700 hours of sunshine, the annual rainfall of 1000 to 1400 mm region can be Cultivation. Schizonepeta tillering biological starting temperature of 3 ℃, the average temperature before winter day down to 5 ℃
