Analysis of the Factors Affecting Output and Quality of Seeds From Chinese Fir Seed Orchard.

Abstract: Based on statinary observations on cone set ting , clima te and soil co dition of five Chinese fir seed orchards in Zhejiang Province, there the influence factors of seeding could be divided into three parts; clone 's genetic train ( or clone 's biology ) , environment , and humans activity ( cultiva tion and management ) . The clone 's genetic train is the basic factor affecting seed production and quality of Chinese fir seed orchard. While the first important factor that makes year 's alteration in seed production is cone flowering in bad polleination, and the Second is the harm of insects and diseases, both could decrease the seed production about 65% . The fator of human 's cultivation and managment is different from else two factors relatedabove, for its initiative and important in improving seed quality and yield condition. The techniques of building the gard at primary period are chiefly as follows: sellecting high genetic gain and will bearing tree clones, and disposing them that are close in flowering within a plot , a nd choosing the sunny-or semi-sunny-slopes to build the Chineses fir seed orchard where ground is open, terrain slopes gently, and the soil moderate fertility or more. When trees begin to seeding , it is important to pollinate in man-made and to controlthe damage of insects anddiseases. Otherwise adequate fertiliaztion and plant thinning must be paid attention to the trees grown in full flourish. Through intensiv e cultivation and management , man could condition the influence of bad environment to the gard, and so ensure to that a high yield continually.
