摘要
通过黄甜竹笋用林集约经营 ,促进早出春笋和高产培育。于秋冬季黄甜竹“孕笋期”采用竹林地灌溉 ,施“孕笋肥”促进其春笋孕育 ,并进行林地覆盖砻糠、稻草等增温、保温 ,促使林地地温稳定、持续达 14℃以上 ,可使黄甜竹春笋提前 2 0～4 5d出笋 ,且早期笋市场热销价高 ,产值翻番 ,其经济效益十分明显。翌年 5、6月份黄甜竹“发鞭期”施用“壮鞭肥” ,以深翻、深层施肥 (深度达表土层下≥ 30cm)可复壮竹林 。
The spring bamboo shoot emergence on an early day and high yield cultivation are promoted with Acidosasa edulis bamboo shoot producing forest intensive management.Flooding on bamboo forest lands is adopted and fertilizers for gestating bamboo shoots are applied to promote gestation of spring bamboo shoots in Autumn and Winter (A.edulis bamboo shoot gestation period),meanwhile,covering forest lands with haulms,etc.for increasing and keeping temperature is conducted to impel forest lands to keep stable ground temperature and over 14℃ contiously,which may make A.edulis spring bamboo shoots emerge 20～45 days earlier,the economic benefit is very evident.Applying fertilizers for making rhizomes vigorous may rejuvenate bamboo forests with deeply tilling and subsoil application (deepness under the topsoil ≥30cm),the objective of A.edulis forest high yield culture in May and June next year is obtained.
