胡杨是盐碱地上的“王牌树”,近水沙漠绿州的“主人”。为大力发展胡杨人工林,乌拉特前旗林研所和西山咀林场自1965年以来,陆续进行胡进杨幼苗移植造林试验,对控制胡杨锈病危害,摸索到一些有效的办法,现予介绍。一、早移逃锈法:这是几年来证实了的成功经验,即头年育苗,第二年5月底前按5×4米的株行距移开,到7、8月间,锈病发生时,幼苗已移到合理密度,加之已给了相应的水肥,提高了幼苗的抗菌能力。二、疏植通风法:选择通风透光好的造林地,以消除发病条件。如我旗党
Populus euphratica is the “ace tree” on the saline-alkali land and near the “master” of the desert water green state. In order to vigorously develop Populus euphratica plantation, Wulateqianqi Forest Research Institute and Xishanzou Forest Farm since 1965, one after another seedlings of Hu Jinyang transplanting afforestation experiment to control the risk of poplar rust control, to explore some effective methods are introduced. First, early evasion of rust law: This is the successful experience of the past few years confirmed that the first year of nursery, the second year by the end of May by 5 × 4 meters away from the plant line spacing, to July and August, rust occurs , Seedlings have been moved to a reasonable density, combined with the corresponding water and fertilizer have been given to improve the antibacterial capacity of seedlings. Second, dredging ventilation method: Choose a good ventilation and afforestation, to eliminate the incidence conditions. Such as my flag party
