摘要: |
植物叶面结露时间长短及露量与农作物病虫害,特别是真菌病害的发生有密切的关系。为监测叶露情况我们设计制作了叶露仪。该仪器适合在植物病虫害发生规律的科学研究和大田作物病害预测预报工作中使用。 |

Abstract: |
Leaf surface wetness duration and amount of dew are often two critical factors in the development and spread of plant diseases,especially of mycosis. Having analysed the advantage and disadvantage of all kinds of the instru- mets of leaf wetness measurement made by other countries,we designed and trial-produced electrical flat-plate impedance sensors and introduced its mate- rial,shape,size,colour surface treatment,and recorder. After test and using the instruments in the laboratories and corp fields,it has... |
