为筛选当地温室专用番茄高产优质品种,选取了2个进口品种和2个国产品种,对其生长发育和产量性状进行了试验研究和动态分析。结果表明:株高、茎粗和主茎叶片数在苗期、盛花期和盛果期,进口品种均高于国产品种;单株果穗数和单株果数,进口品种高于国产品种,单果重和综合产量在早春茬栽培中并无绝对优势。株高、主茎叶片数和单株果数等3个测试指标的动态分析表明,规律一致但分布不同,2个进口品种的动态曲线从苗期到盛果期始终保持上位,说明进口品种在株高、主茎叶片数和单株果数3个生长发育指标上具有明显优势,植株生长旺盛,增产潜力大。
In order to select high-yield and high-quality varieties of tomato for the local greenhouse, two imported varieties and two domestic varieties were selected and their growth, development and yield traits were tested and analyzed. The results showed that the plant height, stem diameter and number of main stems were higher than those of the domestic varieties at the seedling, full bloom and full fruit stage. The number of fruit per plant and the number of fruit per plant were higher in the imported varieties than in the domestic ones. Single fruit weight and comprehensive yield in early spring cultivation has no absolute advantage. The dynamic analysis of the three test indexes such as plant height, number of main stems and number of fruit per plant showed that the dynamic curves of the two imported varieties remained the same from the seedling stage to the fruit-bearing stage, The plant height, the number of main stems and the number of fruit per plant three growth and development indicators have obvious advantages, vigorous plant growth, yield potential.
