METHOD FOR DEVELOPMENT OF PLANTATIONS OF BLACK SAXAUL UNDER CONDITIONS OF SEVERELY CONTINENTAL CLIMATE

摘要

FIELD: agriculture.;SUBSTANCE: method includes autumn arrangement of planting holes with linear placement. Each hole is made with diametre of 0.2-0.6 m with depth of 1.2-1.5 m. Prevernal plantation of 800-900 grafts is carried out on one hectare of pasture. At the same time each graft from saxaul rootstock with age of 9-11 years is formed with length of 1.2-1.5 m and diametre of 15-35 mm with number of alar buds of 8-12 pcs per 1 m of graft length. In process of plantation, at least one of alar buds on graft is located higher than level of pasture day surface. In case there are no natural precipitations in autumn-winter-spring period, cavity of each hole is filled with water of volume of 0.03-0.42 m³.;EFFECT: method makes it possible, at the third - fourth years of black saxaul plantations life, to produce seed material in linear plantations with mechanised process of seeds collection, and to establish stable phytocenosis around each treelike saxaul.;2 cl, 3 tbl
