TECHNOLOGY FOR CREATING FOREST PLANTATIONS FROM POPLARS IN THE GREEN ZONE OF ASTANA

Abstract

The detailed technology of creation of forest plantations from the fast-growing wood species of poplar and care work in the green zone of Astana are given in this article. It is presented information about the state of poplar forest species which are satisfactory for all types of poplar, except for the "Kazakhstani" poplar, which has a good condition. The average bonitet of the main forest-forming species makes up 3.7 which indicates the optimality of the forest location for the natural and climatic conditions of the area and on newly created poplar plantations an area of 0.5 ha in "Akkol" nursery. An inventory of forest poplar plantations was carried out in the allotted samples. One of the agrotechnical methods of accelerated cultivation is the process of cuttings of poplar before planting growth stimulators with zircon, cornevine, heteroauxin, epine, and krezatsinom with different soaking time. To increase the rooted cuttings, biomicrofertilizers "Extrasol" and growth stimulator "Karpansil" were used. Studies have established that the average bonitet of the main forestforming species is 3.7, which is optimal for the natural and climatic conditions of the forest site of the enterprise. The poppy plantations of the poplar of the pyramidal and the Kazakh poplar are affected by a thick-walled sawfly, and the seed plantations of the Kazakh poplar are poplar, aspen leaf and spinal fly. Most (63.8%) of the preserved forest poplar cultures are in good condition and only 8.8% of plantings were in unsatisfactory condition. According to the results of studies of the state of forest cultures on permanent test plots, the agrotechnics of the establishment are given: soil preparation, planting,
agrotechnical care, irrigation, growth stimulators, and technologies and methods of soil cultivation and types of forest cultures
