| Abstract: In order to make full use of the high-quality light and heat conditions in Beijing from March
to May, and maintain the quality of tomato cultivated in substrate, the effects of different planting densities
(4 000, 6 000, 8 000 plants per 667 m2
) on the yield and quality of tomato were studied by changing the traditional
cultivation methods and adopting the cultivation measures such as artificial controlling the plant height, leaving
only 2 ears of fruit and water deficient irrigation in the same facility. The results showed that the soluble solid content
of fruit with treatment of 6 000 plants per 667 m2
was 8.2%, and the yield of fruit was 3 183.6 kg per 667 m2
, which
were all significantly higher than that of the control, and the net income was 2 484 yuan per 667 m2
higher than
that of the control, which was a suitable density of high density cultivation. |
