元谋干热河谷辣木人工林地灌水后不同覆盖措施对土壤水分及辣木物候的影响
Effect of Different Cover after Irrigation on Soil Moisture and Growth Period of Moringa Oleifera Lam in the Dry-hot Valley of Yunmou, Yunnan Province
摘要
Abstract
The effect of different cover after irrigation on soil moisture and growth period of Moringa oleifera was studied. The results showed that soil moisture content in 0-20 cm and 20-40 cm depth in mulched plots were higher than those in non-mulched plots for sandy loam and clayey soil, which leading to a decrease of growing stage of Moringa oleifera. Soil moisture content after 10 days' irrigation in 0-20 cm depth increased 1.2%~4.6% compared to the control for 2-year old Moringa oleifera under plastic films mulch while the value increased 2.6 % ~3.4% under grass mulch, and soil moisture content increased 1.8%~4.7% for 8-month old Moringa oleifera under plastic films mulch while the value increased 1.8%~4.6% under grass mulch. Additionally, the whole trend of soil moisture content in every soil type was increased with the increase of soil depth. Among three different types of soils of this study, clayey soil had obvious effect on the water-holding capacity.关键词
