Cultivation of the Rootstocks of Cherry Lubskaya in Artificial Substrates with the Use of a Special Structure with a Regulated Microclimate Inside

The article contains experimental material devoted to the study and development of technology for intensive cultivation of the rootstocks of the Lubskaja cherry variety from green cuttings in artificial substrates, using for this purpose a special film greenhouse with a regulated microclimate inside. Studies have established that the optimal conditions for the microclimate in the construction are created by hiding the greenhouse frame with a polyethylene transparent film and a ligature cloth. In this case, the amplitude of air fluctuations in the daytime and at night in the greenhouse does not exceed 22-260C, which is optimal for rooting the planted cherry cuttings. Good conditions for the development of cherry rootstocks are created by planting cuttings in an artificial substrate, consisting of such components as river sand and humus in proportions 1 3.
