白蚁危害已成为全印度桉树种植的一个重大问题.从1976—1980年,我们以细叶桉(Eucalyptus tereticornis)为对象,连续4年进行了防治白蚁的田间试验.材料和方法鉴于白蚁极大地危及幼苗成活及幼树生长,故试验工作着眼于苗木和刚定植的幼树.1.供试苗木:将发育3—4月的幼苗移植在大小为12×18厘米的聚乙烯袋内(容器苗)在6、7、8月将容器苗移植至田间定植穴(30×30×30厘米)中.定植穴株行距均为2米.移植时切开容器口,去掉容器;起苗时尽量减少对根系的扰动;定植穴用筛过的壤土填充至近地平面;定植后壅土压实,不要立即施肥和浇灌.
Termite damage has become a major problem for all Indian eucalyptus plantings. From 1976 to 1980, we conducted field trials on termites for four consecutive years from Eucalyptus tereticornis MATERIALS AND METHODS Given that termites are extremely endangered Seedling survival and sapling growth, so the experimental work focused on seedlings and newly planted saplings .1 seedlings: the development of 3-4 months of seedlings transplanted in size 12 × 18 cm polyethylene bags (container seedlings ) The container seedlings were transplanted into the field planting holes (30 × 30 × 30 cm) in June, July and August, and the row spacing of the planting holes was 2 m. Cut the container opening and remove the container during transplantation, Root disturbance; planting hole with screened loam to fill the near-ground plane; soil compaction after planting, do not immediately fertilize and irrigate.
