Due to the methods of Loghinov B.I., Ogievsky V.V. and Hirov A.A. pure and mixed forest crops of Pinus palasiana Lamb at the age of 18-30 years old were carefully researched on 5 permanent experimental grounds. It was determined that the usual pine-tree /pinys pallasiana Lamb/ grows rapidly in Moldova only when it is young. On the black soils it forms friable wood and its plantations are heavily damaged up to total destruction/ when covered with ice/. Therefore oak-pine crops are recommended only in the northern forest holds of the Republic of Moldova on very poor soils with 2 or 3 lines of the pine combined with 1 line of oak planted at the distance of 2,5 m x 0,7 m.
