为了引进适合干旱绿洲区气候环境的茎用莴苣品种,寻求适合该地莴苣种植的最佳密度和栽培模式,于2015年在干旱绿洲区高台县绿色蔬菜产业园区进行了莴苣的品种适应性、适宜密度及栽培方式研究。结果表明:供试品种中W4(“14-Q64”)的综合表现优于其它品种,种植后75d适收,肉质茎长棒形,茎皮最薄,茎肉最厚,商品率最高,单株质量较对照增加了4.56%。同一种植模式,随着种植密度的增大,株高、茎长、茎粗和单株质量均减小;同一种植密度,起垄栽培的株高、茎长、茎粗和单株质量均大于平畦栽培。综合分析表明,“14-Q64”适合在河西干旱绿洲区推广种植,且当地莴苣种植以起垄栽培、播种密度以株行距35cm×30cm为最佳。
In order to introduce suitable varieties of lettuce suitable for the climatic environment in the arid oasis and find out the optimal density and cultivation mode for the lettuce in this area, adaptability of lettuce in 2015 was evaluated in Gaotai County Green Vegetable Industrial Park in arid oasis area, Study on Density and Cultivation Methods. The results showed that the comprehensive performance of W4 ( “14-Q64 ”) was better than that of other cultivars, which was suitable for 75 days after planting. The fleshy stem had the shape of long rod, the thinnest bark, the thickest stem and the highest commodity rate , The quality of single plant increased by 4.56% compared with the control. In the same planting pattern, plant height, stem length, stem diameter and plant weight decreased with the increase of plant density. The plant height, stem length, stem diameter and plant weight Flat 畦 cultivation. Comprehensive analysis showed that “14-Q64 ” was suitable for poplar planting in Hexi arid oasis area, and the local lettuce planting was riddled with planting density of 35cm × 30cm.
