- 摘要:
- 以无限生长类型番茄“春棚一号”为试材,采用单干整枝的方式,研究不同密度和留果穗数对早春大棚番茄植株生长和果实发育的影响。结果表明:增加种植密度并减少留果数有利于早春大棚番茄的前期生长,株高降低,茎粗、叶长增加,使植株粗壮,加速了第一穗果实的膨大,提高了前期产量;改善了品质,使可溶性糖含量、可溶性蛋白质含量以及维生素C含量增加。增加密度、减少留果数不利于植株中后期生长,植株细高,表现出徒长现象。综合产量、效益以及品质,筛选出早春大棚番茄生产宜采用种植密度为90 000 株?hm-2且保留2穗果的栽培方式更好。
- Abstract:
- Using infinite growth type tomato ‘Chunpeng No.1’ as experimental material and alone training way to study the effects of different density and spike number on greenhouse tomato growth and fruit development in early spring.The results showed that increasing the planting density and decreasing the number of remaining fruits were beneficial to the early growth of greenhouse tomato in early spring.The plant height was reduced, the stem diameter and leaf length were increased, which made the plants thick and strong, the enlargement of the first ear fruit were accelerated and which increased the early yield. Soluble sugar content, soluble protein content and vitamin C content were increased, which improve the quality. Increasing the density and reducing spike number was not conducive to the late growth of plants, which made plant thin and height, showing the growth-legged phenomenon.According to the yield, benefit and quality,planting 90 000?hm-2 density and preserving two panicle fruits was a better way of tomato in early spring greenhouse.
