Abstract

The invention relates to the technical field of agricultural scientific research, in particular to a rain shielding test system for crop drip irrigation and micro-spray irrigation. The rain shieldingtest system for crop drip irrigation and micro-spraying irrigation comprises a main liquid applying part, a rain shielding part and a lifting part, the main liquid applying part is used for conveyingfluid to crops, and the lifting part can enable the main liquid applying part to ascend or descend; and the rain shielding part comprises a winding mechanism and rain shielding cloth capable of shielding rain for the crops, and the winding mechanism is used for unfolding or folding the rain shielding cloth. Rainwater can be prevented from affecting quantitative water application to the crops in rainy days through the rain shielding part, the rain shielding cloth can be conveniently and mechanically folded or unfolded through the winding mechanism, and therefore operation is easy; and the mainliquid applying part can ascend or descend through the arranged lifting part, and therefore the main liquid applying part can convey fluid to the crops under different conditions, and water can be quantitatively applied to the crops during raining.

Description

technical field [0001] The invention relates to the technical field of agricultural scientific research, in particular to a rain-shielding test system for crop drip irrigation and micro-spray irrigation. Background technique [0002] In agricultural scientific research, experimenters need to accurately measure the water consumption of crops in different experimental plots. In order to prevent inaccurate measurement of water consumption of crops and unknown changes in field microclimate during rainfall, it is often necessary for multiple people to pass through the unfolded plastic The cloth can cover the experimental area from rain. When it is not raining, many people need to put the plastic cloth away. This method is complicated to operate, and it cannot be used to water the crops during the rain. Contents of the invention [0003] The purpose of the present invention is to provide a rain-shielding test system for crop drip irrigation and micro-spray irrigation, to solve t...
