云岭水果笋高产栽培技术研究

High-yield Cultivation Techniques for Dendrocalamus brandisii Kurz cv. songmingensis Gao Shoots

试验研究了不同地区、不同栽培措施对高氏甜龙竹发笋及笋产量的影响。结果表明:在云南勐海县、普洱市海拔1300~1700 m,重庆市武隆区、四川宜宾市等地海拔600 m以下的地区适合栽种笋用高氏甜龙竹;高氏甜龙竹栽植适宜的株行距为2 m×4 m,栽种时,以每丛留3~4株母竹、米径控制在4~8 cm为宜;在母竹高2.5 m处封顶可促进枝叶生长和笋芽萌发,增加笋产量;施肥、浇水、竹丛覆盖和剥土晒蔸等措施均能提高笋产量。

The effects of different regions and different cultivation techniques on the shoot growth and yield of Dendrocalamus brandisii Kurz cv.songmingensis Gao are studied.The results show that the bamboo species is suitable to be planted in places at the altitude of 1300-1700 m such as Menghai County and Pu er City in Yunnan Province,and at the altitude of less than 600 m like Wulong District of Chongqing and Yibin City in Sichuan.The suitable row spacing for planting the bamboo is 2 m×4 m.When planting the bamboo,it is suitable to keep 3-4 mother bamboos in each cluster and control the diameter within 4-8 cm;the top sealing of the mother bamboos at the height of 2.5 m can promote the growth of their branches and leaves and increase the shoot yield;meanwhile fertilization,watering,mulching and the exposure of stump to air can also increase the yield of shoot.
