| 【目的】对4种秸秆生物反应堆技术在日光温室黄瓜上的应用效果进行比较，筛选出最适合延安地区温室黄瓜种植的秸秆生物反应堆技术。【方法】选取延安地区最常用的行间内置式、行下内置式、外置式和外置式+行间内置式4种秸秆生物反应堆技术，分别测定其对日光温室内CO2体积分数、室内气温、地温及黄瓜农艺性状、产量和抗病性等指标的影响，以不用秸秆生物反应堆技术为对照，对其效果进行综合评价。【结果】与对照相比，4种秸秆生物反应堆技术均能增加温室内CO2体积分数，提高室温和地温，改善农艺性状，提高黄瓜产量。其中，外置式+行间内置式反应堆在提高温室内CO2体积分数（09:00和11:30）及黄瓜株高、茎粗、产量和缩短收获时间方面表现最为明显，温室内CO2体积分数分别较对照提高了160.0%（09:00）、170.8%（11:30），黄瓜株高、茎粗、产量分别提高了13.8 cm，1.1 mm和34.6%，收获时间缩短了6 d；该技术在提高室温、黄瓜根部10 cm地温及降低白粉病和霜霉病病情指数等方面也有较好表现，室温、黄瓜根部10 cm地温分别较对照提高了1.9和2.9 ℃，白粉病和霜霉病病情指数分别降低1.4 和1.7。【结论】在延安地区黄瓜日光温室栽培中，外置式+行间内置式秸秆生物反应堆技术综合表现最为突出，可以进行示范推广。 |

| Abstract: |
| 【Objective】Effects of 4 straw bioreactors on cucumber in solar greenhouse were analyzed to select the most suitable straw bioreactor in Yan’an area.【Method】Four commonly used straw bioreactor types in Yan’an,interline built-in,line built-in,outer built-in,and outer+interline built-in,were selected and their effects on CO2 volume fraction,air temperature,soil temperature,agronomic traits and cucumber yield were measured. Using technology without straw bioreactor as control,the effect of straw bioreactor types were synthetically evaluated.【Result】Compared with the control,all 4 straw bioreactor types increased CO2 volume fraction,room temperature and soil temperature.The agronomic traits and yield of cucumber were improved as well.The outer+interline built-in type had the best increasing effect on CO2 volume fraction (by 160.0% at 09:30 am and by 170.8% at 11:30 am),cucumber plant height (by 13.8 cm),stem diameter (by 1.1 mm),and yield (by 34.6%) and decreasing effect on time of harvest (by 6 days).The technology also improved the room temperature (by 1.9 ℃) and cucumber root 10 cm soil temperature (by 2.9 ℃) and reduced the disease indexes of powdery (by 1.4) and downy mildew (by 1.7).【Conclusion】The outer +interline built-in type was the most suitable for cucumber planting in greenhouse at Yan’an area. |
