不同株距对温室冬春茬番茄生长和产量的影响

Effect of Different Plant Distance on Growth and Yield of Winter-spring Greenhouse Tomato

为了研究温室冬春茬番茄合理的田间群体结构,以及株距对群体配置的影响,试验在相同的垄沟配置下通过改变株距,对番茄的植株生长、果实性状和产量表现进行研究。结果表明,株高、茎粗、幅宽、单株果数和单果重均表现为,随着株距的增大而增加的趋势,对果穗数和果型没有影响,畸形果率随着株距的减小而明显增加,单产处理间没有较大差异,均在115500kg/hm ^2左右;说明在相同的70＋50垄行配置下,株距在25-40cm之间部分性状虽表现出一定的趋势性变化,但均为比较合理的田间群体配置。

In order to seek a rational population structure and investigate the effects of different plant distances on group configuration of winter-spring tomato in the greenhouse, the growth, fruit characters and yields of tomato were studied in the same furrow configuration by changing plant distance. It is found that the plant height, stem diameter, stem width, fruits/plant and fruit weight increased with the increase of plant distance, but the plant distance had insignificant effects on the fruits/plant and fruit type. Insignificant differences in the yield per unit were found among different plant distances, with an average yield of about 115500 kg/ hm ^2 . There were a significant increase of irregular-fruit-rate （IFR） with the decrease of plant distance,. Moreover, some traits showed a certain changes in the plant distance of 25-40 cm, but they were reasonable field group configuration.
