现代温室番茄产量规律及其与环境因子的关系

对现代温室无土栽培的樱桃番茄和中果型番茄进行了3年3大茬的产量测定.结果表明,樱桃番茄年平均株高10 m左右,定植后70 d开始采收,年单株座果32~38层,每层15~30个果实,单果重12~15 g,每株年产果实3 kg左右,全年生长期340 d,采收期270~280 d,果实从开花至成熟需40~70 d,产量高峰分别在12月中旬至元月上旬和4月中旬至7月底.中果型番茄年平均株高6~8 m,定植后100 d左右开始采收,年单株座果22~25层,单果重150 g左右,每株年产果实10 kg左右,全年生长期340 d,采收期240~250 d,果实从开花至成熟70~100 d,产量高峰分别在1月和5~7月.年际间产量变化趋势基本一致,但总产量相差较大.年产量的60%~70%在4~7月份.由相关性分析可得,产量与温度呈显著至极显著的正相关,产量与光照呈正相关,产量与湿度呈负相关.温度与湿度呈显著至极显著的的负相关,温度与光照呈极显著的正相关,湿度与光照呈极显著的负相关.

Tomato production laws and its correlation to the environmental factors in modern greenhouse

The production of soilless-cultured cherry tomato and middle-sized tomato in modern greenhouse has been tested for three years in three rotations.It shows cherry tomato has an average height of about 10 meters per year.The fruit is available 70 days after planting,and single plant sets 30 to 38 layers of fruits per year.Each layer sets 15 to 30 fruits and single fruit weights from 12 to 15 gram.Each plant produces about 3 kilogram fruits a year.It grows 340 days yearly and fruit is available in 270 to 280 days.It takes 40 to 70 days from flowering to mature of fruit.The peak of production is from middle of December to the beginning of January,also from middle of April to the end of July.Middle-sized tomato has a height of 6 to 8 meters yearly.The fruits may be picked 100 days after planting,and sigle plant sets 22 to 25 layers of fruits per year.Three to four fruits are kept in each layer and sigle fruit weights about 150 gram.Single plant produces about 10 kilogram fruits yearly.It grows 340 days in a year and the fruits may be picked in 240 to 250 days.It takes 70 to 100 days from flowering to mature of fruit,and the peak production is found in January,and May to July,respectively.The changing trends of production between years are almost the same,but total production varies greatly.The more important facts affecting total production are temperature and sunshine during the winter.60 to 70 percent production is obtained from April to July.Production is positively relative to temperature,at an extremely notable level.Production is also positively relative to sunshine;however production showed negatively relative to humidity.Temperature is negatively relative to humidity,at an extremely notable level.Temperature is also positively relative to sunshine,at an extremely notable level,while humidity is negatively relative to sunshine,at an extremely notable level.
