Development of new method of growing planting material with closed root system

Abstract

The results of studies of the effect on the growth of Scots pine planting material with closed root system of different periods of growing in the closed and open ground. Outlines the main features of technological operations carried out on the experimental facilities, including the quality of seeds, the kind used containers characteristic substrat e dosage contributed main fertilizer, dolomite and agroperlite. Refer fertilizing system with deadlines of application, type of fertilizer and dosages for the active substance per unit area. Specify the duration growth of seedlings in the greenhouse, and on the polygon rearing. Investigated the height of the overground part and root collar thickness of the stem pine seedlings at the end of the growing season on the various options of growing. Based on the findings formulate conclusions and recommendations for growing seedlings particular purpose. Offer the technology of growing seedlings with closed root system without elevated status, using capillary mats. This technological solution reduces the complexity of the work performed, to improve the quality and biometric parameters of planting mate rial, as evidenced by the comparative characteristics of seedlings grown on trays and capillary mats.
