Abstract:
Taking tomato as test material,the east-west ridging mode of tomato in autumn-winter season was adopt,and three ridge distances treatments were set.Under the same cultivation density,the effects of different ridge distances on the light transmittance,yield and quality of tomato canopy were studied,in order to provide reference the suitable mechanized cultivation mode of tomato in solar greenhouse.The results showed that with the increase of ridge distance,the plant distance was decreased,the difference of light intensity between the north and south sides of the same ridge increased,but the difference multiple of light transmittance between the north and south sides of the middle and upper canopy decreased.The light transmittance of different height canopy of tomato rows was R4 (ridge distance 2.2 m)>R5 (ridge distance 1.8 m)>R6 (ridge distance 1.4 m),indicating that the larger the ridge distance,the better to the increase of rows light transmittance.In the experiment,the fruit color of R4 treatment was changed earlier,the early yield was higher,and the vitamin C,soluble sugar,sugar-acid ratio and soluble protein content in fruit were significantly higher than those of R5 and R6 treatment.At the same time,R4 treatment could significantly reduce the walking distance of manual operation in solar greenhouse,save time,improve work efficiency,and facilitate mechanized production and management.
