Background

The rice and the wheat are important food crops in China, the stable yield and the high yield of the rice and the wheat have very important significance on the national food safety, but the probability of the occurrence of plant diseases and insect pests in the growth period is high, different plant diseases and insect pests can occur in each development stage, and the generated positions are different.

At present, in the process of pesticide application in the middle and later periods of rice and wheat growth, liquid medicine fog drops are difficult to penetrate through a dense rice canopy, most of liquid medicine stays in an upper canopy, and liquid medicine obtained by the middle and lower canopy is less, so that the prevention and control effects on common plant diseases and insect pests such as sheath blight, rice planthopper and the like in the middle and lower rice canopy are poor, and the influence on yield is large.

Currently, there are two main ways to increase the deposition of the liquid medicine in the lower canopy of crops, namely, air-assisted application and sub-canopy application. The air-assisted pesticide application increases air flow on the basis of a common pesticide application machine to improve the fog drop speed and the penetrating capacity, but the influence of the characteristics of crop canopy on the air-assisted pesticide application is large, and the penetrating capacity of the dense canopy of rice and wheat is still insufficient. The spraying heads are deeply arranged inside the crop canopies by applying the pesticide under the row canopies, so that the control effect on the crops with large row spacing and high straw content such as corn, cotton and soybean is obviously improved, but the method is not suitable for the rice and wheat crops with small row spacing.
