早竹保护地栽培筱盖材料的研究

田间试验结果表明,6种不同及盖材料的保护栽培,均提早了始笋期,延长了笋期,增加了笋产量和产值,其中以竹叶、谷株及盖增温效果较为理想。地面及盖酿热就是利用微生物的繁殖、分解、发酵产生的热量增温。酿热温度的高低和持续时间,主要取决于酿热物的破、氮、氧和水的含量。对多种覆盖材料的碳氮比的测定和试验,豆饼、莱饼一类为高温型酿热物,稻草、麦杆一类为低温型酿热物,包括竹叶在内的阔叶树落叶、新鲜厩肥等一类介于两者之间。当碳氮比为20~30,含水量70%,有适量氧气时,微生物活动旺盛,酿热正常而持久。

Mulching Materials on Phyllostachys praocox Forest of Protected Cultivation.

Field experiments revealed that 6 kinds of mulching materials all were effective to move up the beginning Period of bamboo shoots,prolong the Production Period of bamboo shoots,and increase the yield and value.Bamboo leaves and chaff among them were good ferment materials.Raising temperature by ground cover is to use heat Produced from reproduvtion,decompsition and fermentation of microorganism.Ferment temPerature and sustained time depend mainly on carbon,nitrogen,oxygen and water of ferment materials.Soyben cake and cole cake belong to high-temperature ferment materials,rice straw and wheat straw low-temperature,and broad-leaf tree leaves including bamboo leaves,fresh farm manure,etc.middle types.Heating from ferment materials is normal and continued when20~30 of carbon-nitrogen ratio,70%of moisture content,moderate oxygen,and exuberant activity of mieroorganism.
