Effects of adding peat on amelioration of aeolian sandy soil and vegetable growth. 施用泥炭对风沙土改良及蔬菜生长的影响
As a kind of special soil, aeolian sandy soil mainly lies in arid and semiarid areas where sand drift activity is very strong. 沙土是存在于干旱、半干旱地区的一种特殊性土,其岩土工程性质与风沙环境紧密相关。
Yongqing territory aquic soil, brown soil, saline soil, meadow soil and aeolian sandy soil in five categories, of which an area of tidal land of the total land area of 96%. 永清境内有潮土、褐性土、盐性土、草甸土及风沙土五个土类，其中潮土面积占土地总面积的96%25。
It was also confirmed that the corn yield in aeolian sandy soil was a little lower than that in irrigated desert soil even though the N application rate was raised by 127.5 kg/hm~2. 灌漠土与风沙土两个试验点比较
Same trend was found from the field experiment, K application increased corn yield by 39. 1% in the aeolian sandy soil, 24. 5% in the light chernozem soil, and 14. 9% in the black soil. 田间试验亦有相同趋势，在风砂土、淡黑钙土和黑土试验地上施用钾肥分别使玉米增产39.
