黑龙江省东部有许多柞树(Quercus mongolica)林皆伐迹地。在这些迹地上柞树的伐根萌条生长很快,数量很多,给落叶松、樟子松、红松等树种的更新带来了不利影响。这个问题截止到目前都是靠人工或割灌机来解决。但是,上述两种方法不仅效率低,成本高,而且不能有效地控制萌条再生。为此,我们进行了利用化学除莠剂——2,4-D丁酯消除伐根萌条的试验。根据我省特点,选择了两个有代表性的林场,即林口县虎山林场、勃利县通天一林场。试验地面积共5亩,伐根1400个,伐根断面直径12—16厘米。除莠剂为佳木斯农药一厂生产
There are many deforested Quercus mongolica forests in eastern Heilongjiang Province. In these sites, the sprouting and adventitious buds of oak trees grow rapidly and in large quantities, which adversely affects the regeneration of larch, Pinus sylvestris and Pinus koraiensis. Until now, this problem has been solved by manual or brush cutter. However, the above two methods are not only inefficient and costly, but also can not effectively control the regeneration of sprouts. To this end, we conducted the use of chemical herbicide - 2,4-D-butyl spore sprouting elimination test. According to the characteristics of our province, chose two representative forest farms, namely Hokkou County Hushan forest, Boli County Tongtiananyulinchang. Test area of a total of 5 acres, 1400 cutting roots, cutting root diameter of 12-16 cm section. Herbicide for Jiamusi pesticide factory production
