稀土化合物对中华猕猴桃的生理效应研究

稀土元素作为辅助因子参与植物体的代谢活动,中华猕猴桃喷洒稀土化合物后有利于提高叶片的叶绿素含量、可溶性糖及全氮含量,单果重也有明显提高.试验表明,在猕猴桃生长的各个时期喷施2000ppm的稀土溶液,尤其是在幼果期,隔几周喷1次则效果更为明显.

PHYSIOLOGICAL EFFECTS OF RARE-EARTH COMPOUND ON ACTINIDIA CHINENSIS PLANCH

The rare-earth elements can act as auxiliary factors in the metabolic process of plants. The contents of soluble sugar and total nitrogen, as well as that of chlorophyll of the leaves of Actinidia ckinensis Planch could be increased after the plants were sprayed with the rare-earth solution.The average weight of the fruits could be raised also. The results of the test showed: it was profitable to spray 2000 ppm solution on the plant at every periods of its growth. Especially when the plant was treated once after every several weeks during the young fruit period, the result could be better.
