对雷竹地下鞭进行调查研究的结果表明:①雷竹地下鞭鞭段数为5.6条/m ̄2,鞭长为9.6m/m ̄2,体积为4.7×10 ̄(-4)m ̄3/m ̄2。在土中分布可深达60cm,11~40cm之间占80.0%以上,其中2~4龄鞭占总鞭数的85.0%。②壮芽占总芽数的31.1%,集中着生在3~4龄鞭上,发笋能力以3~4龄最强,占当年发笋总数的70.0%~80.0%;③壮芽和发笋位置在鞭段中部最多,6~15节壮芽占58.7%,发笋占70.1%,岔鞭多发生在鞭段前梢,在1~6节占67.0%;④鞭的延伸方向以平行林地和向上生长的类型为多,约占80.0%以上,向上坡伸展的在50.0%左右,向下坡伸展甚少;⑤以土壤肥沃深厚、疏松通气、蓄水保肥性能良好的竹林地鞭量较多,分布结构合理;⑥立竹1000~1100株/1000m ̄2的竹林,地下鞭结构最适宜;随着发育年龄的增大(12年生以上),壮龄鞭和壮芽渐减,老鞭增多。
The results showed that: (1) The number of underground whip whip is 5.6 / m ~ 2, whip length is 9.6m / m ~ 2, the volume is 4.7 × 10 ~ (- 4) m ~ 3 / m ~ 2. In the soil can be distributed up to 60cm, 11 ~ 40cm accounted for more than 80.0%, whichever 2 whistle 4 whip whip total number of 85.0%. ② strong buds accounted for 31.1% of the total number of buds, concentrating on the whip 3 to 4 years old, bamboo shoots ability to shoot the strongest 3 to 4 years, accounting for 70.0% of the total number of shoots 80% ; ③ Strong sprouts and bamboo shoots were mostly located in the middle part of the whip. Among them, the strong sprouts of 6-15 were accounted for 58.7% and the hair shoots accounted for 70.1%. Bifurcated whip occurred mostly in the front of the whip, 67.0%; ④The extension direction of whip is more than 80.0% in parallel woodland and upward, about 50.0% in upward slope, Fertile deep, loose aeration, water and fertilizer to maintain good performance of the bamboo whip whopping more reasonable distribution; ⑥ bamboo 1000 ~ 1100 / 1000m ~ 2 bamboo, underground whip structure most appropriate; as the growing age increased Large (12-year-old or older), strong-aged whip and strong buds decreased, the old whip increased.
