Ecological restoration method for coal gangue dump
The invention provides am ecological restoration method for a coal gangue dump. The method comprises the steps of arranging the coal gangue dump into a gentle slope terrain with an inclination angle of less than 35 degrees, covering the surface of the coal gangue with red soil, and covering the surface of the coal gangue dump with soil for leveling to obtain an arranged coal gangue dump; digging holes at fixed points according to the line spacing of 60 cm and the plant spacing of 40 cm, soaking pigeon pea seeds for germination acceleration, and sowing the pigeon pea seeds soaked for germination acceleration in each hole; or planting vetiver grass seedlings in each hole; soaking pigeon pea seeds for germination acceleration, and planting the soaked and germinated pigeon pea seeds and vetiver grass seedlings at intervals according to holes; then applying farmyard manure, conducting watering every week, and conducting seedling-stage pest and disease damage management, wherein 40% carbendazim suspending agent is used for watering roots in the early stage of seedling-stage morbidity to prevent and control root rot, legume borer adults lay eggs in the peak period, 5% chlorantraniliprolesuspending agent is used for preventing and controlling legume borers, and 40% omethoate emulsifiable concentrate is used for preventing and controlling vetiver aphids, so that ecological restorationof the coal gangue dump is completed. The method is simple, high in operability, low in cost, good in ecological restoration effect of the coal gangue dump and high in greening coverage rate.
本发明提供了一种煤矸石山生态恢复方法，该方法为：将煤矸石山整理成倾角小于35°的缓坡地形，在煤矸石的表面覆盖红壤，覆土平整，得到整理后的煤矸石山；按行距为60cm、株距为40cm定点开穴，将木豆种子浸泡催芽，每穴播种浸泡催芽后的木豆种子；或者每穴种植香根草幼苗；将木豆种子浸泡催芽，将浸泡催芽后的木豆种子和香根草幼苗按穴间隔种植；然后施入农家肥，每周浇水并进行苗期病虫害管理，苗期发病初期用40％多菌灵悬浮剂浇蔸防治根腐病，豆荚螟成虫产卵高峰期，用5％氯虫苯甲酰胺悬浮剂防治豆荚螟，香根草花期用40％氧化乐果乳油防治香根草蚜虫，完成煤矸石山生态恢复。本发明简单，可操作性强，费用低，煤矸石山生态恢复效果好，绿化覆盖率高。
