Abstract

The article examines statistical data on the amount of precipitation in the spring - summer period and substantiates the need for irrigation measures when growing potatoes in the Moscow region. The rationality of the use of drip irrigation as the most economical and effective method of watering has been proved. With drip irrigation, there is practically no danger of excessive watering, causing the leaching of nutrients from the root layer, an increase in the level of groundwater, and an additional load on the drainage network. The use of drip irrigation will make it possible to maintain an optimal water and air balance during the growing season. The possibility of combining technological operations for laying a drip tape and forming potato ridges is considered. It is found that the resistance of the drip tape laying will not create significant traction resistance, so the working equipment can be mounted on the ridge former. The design of a drip tape stacker based on the Grimme GF-75/4 ridge former was developed and a mechanized drip tape was laid in a potato ridge. It has been proven that the implementation of the drip tape laying and the formation of ridges with one machine will increase the productivity of the work and reduce the energy consumption.
