摘    要:为探索设施栽培条件下水竹出笋及幼竹高生长的规律,对设施栽培水竹笋期、退笋率及新竹高生长进行观测,以露天栽培水竹为对照进行对比研究,其中笋期调查以2天为1个观察单元,以笋尖露出地面1~2 cm为标准开始记录,幼竹高生长每天观测1次,至幼竹抽枝展叶高生长基本停止为止.结果表明,设施栽培水竹笋期比露天栽培水竹笋期提早15天,露天栽培水竹总发笋数量占设施栽培水竹总发笋数量的85.1%,设施栽培具有提早出笋和提高出笋量的作用.设施栽培母竹较露天栽培母竹出笋率高16.6%,设施栽培有利于母竹孕笋.设施内外水竹幼竹生长速度都遵循慢—快—慢节律,但设施内幼竹高生长期比露天幼竹高生长期略长,设施内幼竹平均高度高于露天幼竹平均高度.

关 键 词:水竹  设施栽培  出笋规律  高生长

Abstract:

The bamboo shooting period, degeneration rate and new bamboo’s height growth of Phyllostachys heteroclada were observed in order to explore bamboo shoots emergence and young bamboo shoots height growth of Phyllostachys heteroclada inside greenhouses, meanwhile, Phyllostachys heteroclada outside greenhouses were also studied for comparison. Shooting period was observed for one time every two days, and records were made when bamboo shoots grew above ground 1-2 cm. The height growth of young bamboo was observed for one time every day until young bamboo’s leaves and branches grew out and height growth were stopped. The results showed that the period of the bamboo shoots inside greenhouse was 15 days earlier than that of outside bamboo, and the number of open-air cultivation of bamboo shoots of Phyllostachys heteroclada accounts for 85.1% of the total number of protected cultivation bamboo, therefore, the protected cultivation could improve early shooting and shooting quantity. The shoots emergence rate of protected cultivation of mother bamboo was 16.6% high than that of open-air cultivation mother bamboo, so protected cultivation was good for the pregnant of mother bamboo shoots. Both the open-air and inside young bamboos follow the rhythm of slow, fast and slow, but the high growth period within the greenhouse of young bamboo was slightly long than that of open-air young bamboo. The average height of young bamboo within greenhouse was high than that of open-air young bamboo.

Keywords:
