1997～ 1999年在四川省中江县旱坡耕地实施“目”字型种植法具有较好的保土抗旱效益 ,结果表明 :“目”字型种植有蓄水抗旱、增加土温和水土保持效益 ,“目”字型种植土壤蓄水 (0cm～ 40cm)较常规平作多 2 0 5 5m3 /hm2 ,各生育期平均延长抗旱天数 3 3d ,增加土温 0 2 5℃～ 0 94℃ ,且“目”字型种植可使坡土减少地表径流 78%和泥土流失量80 %。“目”字型种植是四川贫中丘陵区旱坡耕地较好的保土抗旱措施。
The results showed that the glyph glyphosic planting in the headland of Zhongjiang County in Sichuan Province from 1997 to 1999 had water storage and drought resistance, increased soil temperature and soil and water conservation benefits, The soil water storage (0cm ~ 40cm) of “Mesh” plot was 2 0 5 5m3 / hm2 more than that of the conventional planted soil, and the drought-resistant days were prolonged by an average of 3 days in each growth period. Soil temperature was increased from 0 2 5 ℃ to 0 94 ℃, “Font planting can reduce slope surface soil runoff 78% and soil loss of 80%. ”Head" font-type planting is poor and hilly area in Sichuan slope farming a better soil anti-drought measures.
