The experimental results showed that N-981 is the most energy efficiency membrane, and N-962 is the highest impurity resistance membrane.
结论为:N-981离子膜电压最低、耗电最小、N-962电压上升速度最慢、抗杂质能力最好;
Furthermore, proportion of total N, available P, available K in soil are dissimilar after the disease invaded: Capacities of resistance on disease will be enhanced if infect trees are cut appropriate.
此外,林地内的土壤元素含量在病害侵入前后也会发生一定的变化:受到轻度砍伐的林地内其P、K含量较高,有利于提高树木对病虫害的抵抗能力。
The results show that fertilizing in autumn after height growth stop can help seedlings absorb N and P and increase cold resistance.
既有速生前期施肥又有秋季施肥的处理,不仅提高了苗木的生长量,而且增强了苗木的抗寒性。
