通过秸秆、黑膜、河沙等覆盖材料对旱地果园土壤环境及果品产量品质等影响的研究,结果表明:覆草、覆膜、覆沙均可作为旱地果园抗旱保墒、提高土壤肥力及果品产量、品质的有效措施;黑膜对果园土壤含水率和秸秆对土壤有机质含量的影响最显著,分别较对照提高了17.73%和80.9%;黑膜667m2净增收入最高,为旱地果园覆盖首选材料,秸秆次之,河沙最低。
The results showed that straw mulching, film mulching and sand mulching could be used as drought-resistant and soil-moisture-preserving in dryland orchards and soil fertility and fruit yield were increased by covering straw, black film and river sand on the soil environment and fruit yield and quality of dryland orchards. , The quality of the effective measures; black film on the soil moisture content of orchard and straw on the soil organic matter content of the most significant, respectively, compared with the control increased by 17.73% and 80.9%; black film 667m2 highest net income for dryland orchard covering the preferred material, Straw followed, the lowest river sand.
