雨季沙地上地温高、墒情好、风蚀沙埋比较轻微,适宜进行直播造林.出苗快,成活率也较高.但是直播造林有一个大问题,就是易遭鼠害.特別是播种以后的1～2天内,常在夜间被鼠类逐垅逐穴地将种子扒出来吃掉. 鼠类危害的主要目标是有新土痕迹的地方.所以,我们采取了“原土、原草、回原位”和“空城计”的方法播种,以迷惑鼠类,给它们造成错觉,从而减少种子被鼠类扒出吃掉的现象发
Rainy season sandy ground temperature is high, moisture is good, wind erosion sand is relatively light, suitable for direct seeding afforestation. Emerging rapidly, higher survival rate .Background afforestation has a big problem, is susceptible to rodent infestation, especially after sowing 1 ~ 2 days, often at night by rodents chattering the seeds razed out to eat the main purpose of rodent hazards is a place where new traces of soil, so we have adopted the “original soil, grass, back in situ ”And“ empty city plan ”method to sow, in order to confuse the rodents, give them the illusion, thereby reducing the seeds rodent out by eating the phenomenon of rats
