经研究,利用银灰色遮阳网、黑色遮阳网、无纺布和芦帘4种覆盖材料在夏末高温季节进行搭棚覆盖,培育秋黄瓜秧苗,棚内的日平均温度下降在0.3~1.6℃,日最高温度下降0.3~5.3℃;日平均透光率为19.2%~59.4%;秧苗综合素质以银灰色遮阳网覆盖的处理为最好,其他各处理均不同程度地优于露地育苗。
After researching, four kinds of covering materials, such as silver shade net, black shade net, non-woven fabric and reed curtain, were scaffold covered in high temperature season in late summer to cultivate autumn cucumber seedlings. The daily average temperature in the shed decreased 0.3 ~ 1.6 ℃, the maximum daily temperature dropped 0.3 ~ 5.3 ℃; the average daily light transmittance was 19.2% ~ 59.4%; the overall quality of seedlings covered with silver shade net was the best, the other All treatments were better than open field seedlings to varying degrees.
