Effects of afforestation of farmland shelterbeltwith clones or cultivars of S alix jiangsuensis and S. viminalis and their shading performances were investigated. Results showed thatboth survival and preservation rates of the S. jiangsuensis 194 were 96. 6 and 93. 2 %
respectively. There were no differences of survival and preservation rates among differentcultivars or clones and differentplanting spaces. Tree heightin-crementof S. jiangsuensis was higher than thatof S. viminalis
indicating thatS. jiangsuensis is a suitable species for farmland shelterbelt. Shading index and shading degree of the 62year-old S. jiangsuensis 172 (spacing 3 m ×6 m) were 56. 62 % and 13. 31 %
respectively
exceeding the upper limitof farmland shelterbelt. Therefore
the S. jiangsuensis 172 should be shinned properly in the fifth year of planting to meetthe related standards.
