ENVIRONMENTAL AND ECONOMIC EFFICIENCY OF CULTIVATION OF CHINESE MAGNOLIA (SCHISANDRA CHINENSIS (TURCZ.) BAILL.) DEPENDING ON PROCESSING OF BIOLOGICAL GROWTH STIMULANTS

Abstract

The article investigates environmental and economic efficiency o f producing Chinese magnolia seedlings. Key economic indicators o f producing Chinese magnolia seedlings using biological growth regulators are analyzed. The ways to improve the economic efficiency o f producing Chinese magnolia seedlings are substantiated.The obtained results indicate that using biological growth regulators for practical purposes stimulates the process o f rooting Chinese magnolia seedlings, increases the effectiveness o f vegetative propagation o f it. Biostimulators o f plant growth Stimpo and Regoplant have a positive effect on seedlings increasing plant growth and are safe for the environment.On the basis o f conducted studies it is found that despite the increase in material costs related to the purchase o f materials and biological stimulants, care o f seedlings, cost price o f grown seedlings, labor costs and other economic indicators decreased by 4 times.Evaluation o f the economic efficiency on studying methods and timing o f transplantation for prolonged growth o f rooted green stem cuttings o f varieties and forms o f Chinese magnolia suggests a high degree o f effectiveness o f these variants.
