板栗园桑寄生植物的生物学特性及危害的初步研究

Apreliminary Study of the Biological Properties and Harm of Parasitic Loranthus Plants in the Orchard of Chinese Chestnuts

桑寄生植物从寄主板栗树的体内吸取水分和矿质营养,对寄主构成危害,其危害程度与寄生植物的生物学特性和环境条件有关,而不同种类的寄生植物对寄主个体和种群造成的危害亦不相同.

Parasitic loranthus plants absorb water and non-oganic materials from their hosts-Chinese chestnuts and thus do harm to them. The degrees of harm are based on the biological properties and the conditions of surroundings of the parasitic plants. Different parasitic plants do different degrees of harm to their hosts. themselves and their colonies.
