摘要
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 6 92 0 .2kg/hm2 ,增加34.5 % ,达极显著水平 ,增加纯收入 132 6 2 .9元 /hm2 。应用覆膜厢作技术表现出了全程节水、前期增温、改良土壤。
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.
