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 *** *** results showed that mulching film increased daily average temperature and the effect order was sunlight > after-rain > *** soil temperature of grass cover and block cover were lower than that of open *** 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%,*** the germination rate of grass covering was lower than that of the control.
