绿竹笋芽提前萌发促成技术研究

Study on Shooting Hastening Techniques of Dendrocalamopsis oldhami

以绿竹林高产、高效、优质和可持续经营为目标,为促成笋芽提前萌发,采用3种措施对比试验表明:林地覆盖和提前晒目竹笋早出效果明显.3月初晒目20d,可提前出笋36d,笋期延长32d;2月中旬以砻糠覆盖30cm厚可提前出笋57d,笋期延长17d;土壤水分供应对笋期影响不显著,但显著提高出笋数量和竹笋产量、质量.绿竹林地覆盖和提前晒目可作为竹业实用技术推广,指出应就竹林土壤水分精准化供应和长期立地生产力维护等技术开展深入研究.

Aiming at high yield, fine quality, efficient production of bamboo shoots and sustainable management of Dendrocalamopsis oldhami plantation, a shooting hastening experiment was conducted with varied measures of cultivation. It was showed by the experiment that the shooting was evidently hastened by sun bathing of the bamboo shoots and mulching the stand ground surface with organic substance. It was showed that bamboo shooting can be brought forward by 36 days compared with control, and the shooting period was prolonged by 32 days by bathing the shoots in the sun for 20 days in early March. The shooting stage was moved up by 57 days, and the shooting duration was prolonged by 17 days through mulching the ground surface of the stand with 30 cm in thickness of rice chaff in mid February. Though water supply did not significantly influence the shooting duration, it significantly promoted shooting quantity and quality of the bamboo shoots. It was recommended that ground mulching and sun bathing the shoots be popularized as feasible techniques in shoot production of Dendrocalamopsis oldhami, and it was suggested that studies be deepened on precise irrigation and productivity maintenance of the stand while hastening the bamboo shooting is applied.
