青海东部山旱地土壤耕作主要集中在春秋两季。据观测,春季在解冻前打耱保墒的麦田比对照0～40cm土体中共增加水分31.6mm。春翻施肥比秋施肥播前土壤水分少1.34%。播后耙地一遍和两遍的麦田比未耙地的水分高0.13%和1.76%。中耕一次和两次麦田比未中耕的水分高1.35%和1.99%。伏耕、秋耕、板茬麦田翌年播前土壤水分含量分别为22.04%、20.16%、14.28%。春小麦收后及时耕翻、收后4天翻、收后7天翻、收后10天未翻1m深土体中水分含量分别为293mm、263mm、237mm。“三九”碾地与未碾地的土壤水分相比,比播前0～10cm的高3.2%,比10～20cm的高2.1%,比出苗期0～10cm的高2.6%,比10～20cm的高1.4%。
The cultivation of soil in mountain dry land in the eastern part of Qinghai is mainly concentrated in spring and autumn. According to the observation, before spring thawing wheat straw soil moisture than the control 0 ~ 40cm soil total increase of 31.6mm. Spring turned fertilization than before fertilization sowing soil moisture 1.34% less. The fields harvested again and twice after sowing were 0.13% and 1.76% higher than those not harvested. Cultivation time and two wheat fields were 1.35% and 1.99% higher than the non-cultivated water. The soil water content before and after sowing in the following year was respectively as 9.74%, 20.16% and 14.28%. After harvesting, the spring wheat was tilled in a timely manner, turned 4 days after harvesting, turned 7 days after harvesting, and the moisture content in the 1m soil layer after the first 10 days of harvesting was 293mm, 263mm and 237mm respectively. Compared with 0 ~ 10cm before sowing, soil moisture of “39” grind was 2.1% higher than that of 10 ~ 20cm, 2.6% higher than that of 0 ~ 10cm at seedling stage, The height of 20cm is 1.4%.
