- 摘要:
- 以“丰收128”番茄为试材,采用完全随机区组设计,研究了不同密度和行距对番茄生长及产量的影响,以期确定更适合于宁夏大跨度塑料大棚番茄栽培的最佳模式,为番茄优质高产高效栽培提供参考依据。结果表明:A3B3处理有利于植株冠层内光能的捕获及利用,一定程度上提高了光能的利用率,也有利于植株根系活力的增强,667 m2产量为21 447.31 kg,相比A1B3处理产量增幅达48.48%;其有机酸含量最低为0.27%,可溶性糖最高为2.35%。因此,A3B3处理为适宜于机械化操作的大跨度塑料大棚较理想的栽培模式。
- Abstract:
- The effects of different densities and row spacing on tomato growth and yield were studied by using a completely random block design with ‘Harvest 128’ as the test material,in order to determine the best tomato cultivation model suitable for large-span plastic greenhouses in Ningxia and to provide scientific basis for tomato cultivation with high quality,high yield and high efficiency.The results showed that the A3B3 treatment was beneficial to the capture and utilization of light energy in the canopy of the plant,to a certain extent,the utilization rate of light energy was improved,and the root activity of the plant was enhanced.The production of 667 m2 was 21 447.31 kg.Compared with A1B3 treatment,the yield increased by 48.48%.The content of organic acid was the lowest,0.27%,and soluble sugar was the highest at 2.35%.Therefore,A3B3 was an ideal cultivation mode suitable for mechanized operation of large-span plastic greenhouses.
