Disinfection with chickens present is an important measure for green product production
Disinfection with chickens present is an effective measure for preventing and controlling avian influenza and Newcastle disease on large-scale chicken farms. It is especially necessary during periods with more spring winds, and for chicken houses housing flocks of different ages. The specific method of operation: choose an appropriate time. In winter, when temperatures are low, it is best to choose midday when the temperature is high, so the aerosol evaporates quickly, the chickens breathe it in quickly, absorb it quickly, and it takes effect quickly. In spring and summer, when the normal temperature is above 20°C, it is best to choose the afternoon or evening, when the temperature is constant and the aerosol evaporates slowly, so the floating disinfection time inside the house is long.

Cotton mirid bugs still require priority control at present
This year's cotton pest situation differs from previous years.

In fact, pests in the later stage of cotton growth are often another important factor preventing high cotton yields. The main pest in the later stage of cotton growth is the cotton mirid bug, a hemipteran cotton pest with extremely strong reproductive capacity, whose damage period lasts from mid-May

Agricultural drones have wide applications, excelling at spraying, fertilizing and disaster surveying
Nowadays drones are being used more and more widely, and they are also used in agriculture. Let's take a look together. Unmanned aerial vehicles are seen as a promising new capable assistant for the future development of agriculture. Not only has the Civil Aeronautics Administration been busy drafting regulations, under which anything above 250 grams will in future require real-name registration, but all sectors are also actively investing in developing agricultural and other uses of drones. The Agricultural Research Institute of the Council of Agriculture, Executive Yuan, has set up a drone team and is currently building experimental data; in future it is expected to establish a set of operating manuals for farmers to refer to.
