摘要：Effects of different treatments,including mulching film,grass cover,block cover,water retaining agent,rooting powder and open field(control),on direct seeding of Gleditsia sinensis Lam.were studied.The results showed that mulching film increased daily average temperature and the effect order was sunlight > after-rain > cloud.The soil temperature of grass cover and block cover were lower than that of open field.After 6-day sunlight,soil moisture content of mulching film,grass cover and water retaining agent were higher than that of open field,with increased by 24.4,21.4,2.5 and 1.0 g·kg-1,respectively.30 days after seeding,the germination rates with the methods of mulching film,rooting powder block cover,water retaining agent were higher than that of the control,with increases of 12.11%,4.20%,3.10%,and 2.10%,respectivey.While the germination rate of grass covering was lower than that of the control.
Effects of different treatments, including mulching film, grass cover, block cover, water retaining agent, rooting powder and open field （control）, on direct seeding of Gleditsia sinensis Lam. were studied. The results showed that mulching film increased daily average temperature and the effect order was sunlight 〉 after-rain 〉 cloud. The soil temperature of grass cover and block cover were lower than that of open field. After 6-day sunlight, soil moisture content of mulching film, grass cover and water retaining agent were higher than that of open field, with increased by 24.4,21.4,2.5 and 1.0 g · kg^-1, respectively. 30 days after seeding, the germination rates with the methods of mulching film, rooting powder block cover, water retaining agent were higher than that of the control, with increases of 12.11%, 4.20%, 3.10%, and 2. 10%, respectivey. While the germination rate of grass covering was lower than that of the control.
