On sandy terraces in the basin of Central Don hilly sands are the most difficult for forest improvement. During their development 4 technologies of creation of forest cultures are developed and approved: 1 - soil preparation by furrows, hand planting; 2 - soil preparation by furrows, the mechanized planting; 3 - the mechanized planting with simultaneous cultural operations; 4 - preliminary ridging, prelanding cultivation, the mechanized planting (modern technology). Efficiency of technologies is estimated on the following indicators: 1) survival; 2) safety of plants in forest cultures; 3) biometric indicators of plants; 4) structure of forest stands on diameter; 5) level of influence of tree species in mixed plantations. Survival of forest cultures at technical acceptance made 97-99% when using technologies ¹ 1-3 and less than 50% - when using technology ¹ 4. Advantage of hand planting over mechanized is shown since 4-6 growth. Lack of modern technology is large number of technological operations...
