不同栽培模式对夏茭生长发育及效益的影响

[目的]探索夏茭适宜的栽培模式.[方法]以双季茭白龙茭2号和浙茭6号为试验材料,采用大棚覆盖、小拱棚覆盖和露地栽培3种模式,分别考查分析不同模式对茭白萌芽、生长发育及其经济效益的影响.[结果]利用大棚、小拱棚覆盖栽培,均可以提高早期温度,促进茭白萌芽,促进提早上市,提高市场销售价格.但小拱棚栽培保温效果相对大棚栽培较差.[结论]夏茭栽培以大棚、小拱棚覆盖栽培模式较为适宜.

Effect of Different Cultivation Modes on Growth and Development and Economic Benefit of Summer Water Bamboo

[Objective]To explore the optimal cultivation modes of summer water bamboo.[Method]Taking two water bamboo （Zizania latifolia Turcz.） cultivars Longjiao No.2 and Zhejiao No.6 as test materials,three cultivation modes including greenhouse coverage,small arch coverage and open field,were used to investigate the effect of the different modes on the germination,growth and development,and the economic benefit of the water bamboo.[Result]The results showed that cultivated in greenhouse coverage and small arch coverage could incrcase early stage temperature,promote germination of water bamboo,appear on the market earlier,and improve the market price.As far as the insulation effect was concerned,the small arch coverage was inferior to the greenhouse coverage.[Conclusion]Greenhouse coverage and small arch coverage modes are more suitable for summer water bamboo.
