Influence of planting density to growth and production property of Ceratoides ewersmanniana cv. YiLi

Ceratoides ewersmanniana cv.YiLi is distributed only in the northern of Xinjiang,China.It has good soil and water conservation and sand-fixing function,and plays an important role in the Xinjiang desert vegetation restoration and ecological construction.This study used 10 different density treatments,and explored the influence of planting density to the growth characters and production property of C.ewersmanniana cv.YiLi.The results showed that planting density has a great influence on growth and production property of C.ewersmanniana cv.YiLi.Individual growth and development of low-density was able to form a reproductive branch and reach relatively high yield,so that in the absence of irrigation density Ⅰ-Ⅴ ie 4-30 plants·m-2,preserve seedling 2 666-20 000 plants·666.7 m-2 is the most reasonable treatment strain.In the northern,cultivating the C.ewersmanniana cv.YiLi and reseeding the grassland naturally can be improved and under lower planting density.This can provide a scientific basisof a reasonable planting density to cultivate C.ewersmanniana cv.YiLi and reseed the grassland.
