【摘要】：以番茄“佳西娜”为试验材料,采用北京市农林科学院蔬菜研究中心研发的封闭式无机基质槽培种植方式,栽培基质为珍珠岩,研究了每日供液时间对番茄生长发育的影响,以及不同体积大小的栽培槽铺设无纺布对番茄生长发育的影响。本试验对番茄的形态指标、生理指标、产量、果实品质、水肥利用效率、基质含水量分布以及根系分布进行调查,对所测数据进行综合分析可得出以下结论:1.供液时间过短或过长均不利于番茄植株的生长;随着供液时间的增加,果实产量呈现增加的趋势,但供液时间大于2h后,产量差异不显著,果实品质和根系活力整体呈现下降的趋势;水肥利用效率受到果实产量和水肥利用量两个因素共同影响,T2(供液2h)处理的水肥利用效率是最高的,比CK高5.11%,T5处理的水肥利用效率是最低的,比CK低12.83%;在根系分布和基质含水量分布方面,随着供液量的增加,各基质层的根重量和基质含水量均呈现增加的趋势。建议封闭式无机基质槽培番茄供液时间为T2(供液2h)。2.相对于小栽培槽,大栽培槽显著提高了番茄的株高、产量、植株生物量和根系活力,但是降低了水肥利用效率和基质含水量;铺设无纺布提高了茎粗、产量、植株生物量、水肥利用效率和基质含水量,并且提高了无纺布上层的根量,降低了无纺布下层的根量。建议大栽培槽铺设无纺布更有利于番茄生长发育。
[Abstract]:The effect of daily liquid supply time on tomato growth and development was studied using tomato "Jiaxina" as the experimental material, the closed inorganic substrate culture cultivation method developed by vegetable Research Center of Beijing Academy of Agriculture and Forestry, and the cultivation substrate as perlite. The effects of different volume of cultivation grooves laid by non-woven cloth on the growth and development of tomato were studied in this paper, including morphological index, physiological index, yield, fruit quality, water and fertilizer utilization efficiency. After investigating the distribution of water content and root system, the following conclusions can be drawn: 1. Too short or too long liquid supply time is not good for the growth of tomato plants, and with the increase of liquid supply time, The fruit yield showed an increasing trend, but when the time of liquid supply was more than 2 hours, the yield difference was not significant, and the fruit quality and root activity showed a downward trend as a whole. The water and fertilizer use efficiency was the highest in the treatment of T2 (water supply 2 h) and the lowest in the treatment of 5. 11% T5 higher than that of CK, which was affected by two factors, fruit yield and water and fertilizer utilization. The distribution of root system and water content of substrate increased with the increase of liquid supply. The root weight and substrate moisture content of each substrate layer showed an increasing trend. It was suggested that the time of supplying liquid to tomato in closed inorganic substrate slot culture was T _ 2 (2 h ~ (-1) 路2). Compared with the small cultivation slot, the plant height and yield of tomato were significantly increased by the large cultivation slot. Plant biomass and root activity, but decreased water and fertilizer utilization efficiency and substrate water content; laying non-woven cloth increased stem diameter, yield, plant biomass, water and fertilizer utilization efficiency and substrate water content, and increased root amount in the upper layer of non-woven fabric. It is suggested that laying non-woven cloth in large cultivation slot is more beneficial to tomato growth and development.
