东北黑土区蓝靛果埂带栽植技术及其水保效益

Cultivation of Lonicera Edulis on Earth Bank and Its Benefit of Soil and Water Conservation

通过在东北黑土区梯田埂和地埂上栽植蓝靛果试验,对蓝靛果的生长发育、水保作用和经济效益进行了观测与分析。结果表明,蓝靛果适于埂带种植,它抗逆性强,方便管理,生长迅速,枝叶茂盛,适应性强。埂带蓝靛果茎叶和根系发达,固埂防冲能力强,蓄水保土效果显著。种植第3年,蓝靛果的保水效益达到82%以上,保土效益达95%以上,经济价值达24 000元/hm2。研究表明,可以在东北黑土区推广蓝靛果的埂带栽植技术。

The growth process of Lonicera edulis and its soil and water conservation and economic benefit were studied by field experiment both in terrace and earth bank in the black soil area of the Northeast China. The results showed Lonicera edulis was suitable vegetation planted in terrace and earth bank. It had the characteristics which including good tolerance, easily cultivated, fast growth, high densities of leaves and roots and good adaptability. Based on high coverage of leaves and high density of roots, Lonicera edulis had the powelful capability of solid ridge and scour prevention, therefore its capability of water and soil conservation was significant. At the third year after Lonicera edulis were planted, its benefit of soil and water conservation reached more than 82% and 95%, respectirely, thus, the economic income reached 24 000 yuan/hm2. Therefore, Lonicera edulis can be recommend to plant in terrace and earth bank in the black soil area of the Northeast China.
