苎麻在湖南平原地和山坡地栽培的比较试验

The Comparative Test of Ramie Grown in Plain and Hillside in Hunan

为了解苎麻山坡地栽培特点,以中苎一号为材料,采用大田试验,设计山坡地和平原地种植苎麻两个不同处理,比较分析山坡地和平原地种植苎麻的经济性状指标及亩产差异。研究结果表明:山坡地苎麻平均单株株高、茎粗、皮厚、鲜皮重、干纤维重等经济性状指标均低于平原地苎麻;全年平均单蔸产量比较发现,苎麻平原地有效株数、总鲜重、鲜麻重、干纤维重均显著高于山坡地,折合平均亩产平原地高于山坡地栽培。该研究结果可为苎麻山坡地的高产栽培及合理肥水管理提供依据。

In order to understand the cultivation characteristic of ramie planting in the hillside, with Zhongzhu No. 1 as experimental material, based on the field test, two treatments （plain and hillside） were set to investigate the economic traits and average yield per mu. The results showed that the average plant height, stem diameter, skin thickness, fresh weight, dry weight of ramie economic characters grown in the hillside were lower than that in the plain. Comparing to the annual average single plant yield, the effective number of plants, total fresh weight, fresh weight, dry fiber weight of ramie grown in the plain were significantly higher than that in the hillside. The annual average dry weight yield of ramie per mu grown in plain was higher than that in the hillside. The results could provide a basis for high yield culti- vation and rational fertilization of ramie grown in the hillside.
