莲藕覆膜厢作高效栽培技术研究

选用4个莲藕品种,对莲藕覆膜厢作栽培进行了2a的多点试验。结果表明：应用覆膜厢作技术,莲藕的生物性状、经济性状均显著优于常规下栽培的莲藕、覆膜厢作处理比对照增产莲藕6920.2kg/hm^2,增加34.5%,达极显著水平,增加纯收入13262.9元／hm^2。应用覆膜厢作技术表现出了全程节水、前期增温、改良土壤、早熟高效等综合功能。

Studies on High Efficient Cultivation Technology of Lotus Root by Tectorial Planting in a Field

Choosing 4 lotus root varieties, tectorial planting in a field of lotus root was experimented at different spots in two years. The results showed that the biology and economic characters of lotus root by tectorial planting in a field were better than which by traditional planting, the increasing yield of lotus root was 6920.2 kg/hm 2 , the amplitude was 34.5%, the varation arrived to high significant level, the increasing income was 13262.9 yuan/hm 2 . Technology of tectorial planting in a field had many comprehensive advantages such as saving water in the full time, increasing temperature in prophase, improving the soil, earliness and high efficiency.
