通过对鸭茅不同播期内出苗率和杂草发生情况的调查,确定了盆周山区海拔1000m以下地区鸭茅草地建植的适宜播种期为10月。不同播量试验证明,在湿润土壤和高降雨量条件下,10月份播种的适宜播量为20～27kg/hm2。建植第一年的鸭茅草地氮肥施用量以80kgN/hm2为宜,鲜草产量为7.07×104kg/hm2,但这一施肥量不足以满足夏季(6月以后)和后期生长的需求,此时应及时补充肥料以保证秋季鸭茅的旺盛生长。 According to the investigation of the emergence rate and weed occurrence in different sowing times, the suitable sowing date for the construction of canopy grass in the area around 1000m above sea level in the mountainous area around the basin was determined as October. Different sowing experiments showed that in wet soil and high rainfall conditions, sowing in October the appropriate sowing rate of 20 ~ 27kg / hm2. In the first year of planting, the dosage of nitrogenous fertilizer for D. sinensis was 80kgN / hm2 and the fresh grass yield was 7.07 × 104kg / hm2. However, this amount of fertilizer was not enough to meet the demand of summer (after June) and later growth. Should be timely replenishment of fertilizer to ensure the strong growth of autumn Dactylis.
