- Abstract:
- In order to screen suitable plant protection machineries for greenhouse-type vegetables to solve the difficulties of protection operation and low utilization of pesticides,four advanced and common plant protection machineries were chosen based on the extensive research on plant protection equipment and pesticide application techniques,and their law of droplet deposition and distribution,deposition amount of pesticide solution,effective utilization rate of pesticide,ground loss and operation efficiency in tomato canopy in greenhouse were tested.The results indicated the variation coefficients of positive deposition amount of knapsack aerosol sprayer,hot aerosol sprayer,rotary lance and knapsack sprayer on the front of the blade were 75.38%,134.98%,62.87% and 45.53%,respectively,while that of the negative deposition amount were 82.85%,303.28%,64.55% and 44.70%,respectively.The ground loss amount increased in the order of knapsack aerosol sprayer,hot aerosol sprayer,knapsack sprayer and rotary lance.Four advanced and common plant protection machineries were chosen based on the extensive research on plant protection equipment and pesticide application techniques,and their law of droplet deposition and distribution,deposition amount of pesticide solution,effective utilization rate of pesticide,ground loss and operation efficiency in tomato canopy in greenhouse were tested.In order to screen suitable plant protection machineries for greenhouse-type vegetables to solve the difficulties of protection operation and low utilization of pesticides.The results indicated the variation coefficients of positive deposition amount of knapsack aerosol sprayer（W1）,hot aerosol sprayer（W2）,rotary lance（W3） and knapsack sprayer（W4） on the front of the blade were 75.38%,134.98%,62.87% and 45.53%,respectively,while those of the negative deposition amount were 82.85%,303.28%,64.55% and 44.70%,respectively.Utilization rate of liquid medicine,W1＞W2＞W4＞W3.By evaluating the performance of different plant protection tools,the suitable tools and application methods for greenhouse plant protection were determined,so as to achieve the goal of increasing the utilization rate of pesticides.
