| 中文摘要:研究了垄沟式太阳能消毒、石灰氮结合太阳能消毒和垄鑫熏蒸土壤3种消毒方法对日光温室剖面温度和土壤营养特性的影响。结果表明:垄沟式太阳能消毒提高土壤剖面温度高,速度快,对土传病害有良好的防治效果,土壤速效P、土壤速效K含量分别比对照增加0.5%和31%,而土壤速效N、有机碳的含量分别比对照降低17%、12%;施用石灰氮土壤速效P和土壤速效N分别比对照增加94%和52%,土壤速效K变化不明显,有机碳比对照降低15.8%;施用垄鑫处理土壤速效钾和土壤速效N分别增加10.7%和22.5%,土壤速效P变化不显著。垄沟式太阳能消毒对更深层的土壤养分含量影响比石灰氮结合太阳能消毒和垄鑫熏蒸土壤更为明显。 |

| Abstract:Effect of three soil disinfectants which were solarization of soil in ridge and furrow with plastic film mulching,calcium Cyanamid with solar energy and 98% dazomet fumigation on soil temperature and soil nutrient were studied in sunlight greenhouse. The results showed that the soil temperature of solarization of soil in ridge and furrow with plastic film mulching raised higher and faster than other,its control effect on the soil-disease were more obvious. Available P content and available K in soil were increased by 0.5% and 31% respectively,compared with CK,but available N and soil organic matter decreased by 17% and 12% respectively,compared with CK; Available P and available N of calcium Cyanamid was increased by 94% and 52% respectively,compared with CK,available K vary is not obvious,soil organic matter content decreased by 15.8% compared with CK; Available K and available N of dazomet fumigation increased by 10.7% and 22.5% respectively,and available P were no significant difference by using three soil disinfectant. The effect of solarization of soil in ridge and furrow with plastic film mulching on soil nutrient in deeper was more obvious than calcium cyanamid with solar energy and dazomet fumigation. |
