| 摘 要： | 在河套灌区以不覆盖为对照,测定了地膜覆盖、秸秆覆盖、地膜+秸秆覆盖对土壤水热和番茄生长的影响。结果表明,地膜覆盖提高了土壤温度,而秸秆覆盖、地膜+秸秆覆盖降低了土壤温度,其中秸秆覆盖降低的幅度较大。在番茄生育前期不同覆盖可提高0—50cm土层的土壤水分含量,其中地膜覆盖效果最好。地膜覆盖使番茄产量提高了222.61%,地膜+秸秆覆盖使产量提高了17.04%,而秸秆覆盖则使产量降低了3.06%。地膜覆盖使水分利用效率提高了93.83%,地膜+秸秆覆盖使之提高了5.90%,秸秆覆盖则使水分利用效率降低了19.29%。河套灌区番茄播种时以地膜覆盖为宜,不宜采用秸秆覆盖。 |

| Abstract: | Compared with the control of bare surface,the effects of plastic-film mulching,corn-straw-only mulching,and film-plus-straw mulching on the soil temperature,soil moisture and the growth of tomato were monitored in Hetao irrigation area.The results showed that the plastic-film mulching increased the soil temperature,and corn-straw mulching and film-plus-straw mulching reduced the soil temperature.In comparison,corn-straw-only mulching exerted stronger effects than film-plus-straw mulching.All the mulching tr... |
