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 treatments resulted in increases of soil moisture within 0—50 cm in the early stage of tomato growth

while the plastic-film mulching was the best.The yields of tomato with plastic-film mulching and film-plus-straw mulching were 222.61% and 17.04% higher than the control

respectively.However

the yield with corn-straw mulching was 3.06% lower than the control.The water use efficiency under plastic-film mulching and film-plus-straw mulching were 93.83% and 5.90% higher than the control

respectively.Similarly

water use efficiency of corn-straw-only mulching was 19.29% lower than the control.The results indicated that the plastic-film mulching was suitable

and the corn-straw mulching was undesirable in sowing time for tomato production in Hetao irrigation area.
