Abstract:Taking tomato variety‘Luola’as material,5 treatments were set up:CK,33 300 plants ·
hm-2 with 6 ears;T1,49 500 plants · hm-2 with 4 ears;T2,66 000 plants · hm-2 with 3 ears;T3,49 500 plants ·
hm-2 with 2 ears every other plant and another plant with 6 ears;T4,66 000 plants · hm-2 with 2 ears every
other plant and another 4 ears.The paper studied the effects of different planting densities and fruit retention
methods on tomato plant growth,yield,quality and population microenvironment.The results showed
that T2 and T1 treatments had the higher average temperature.The SPAD value of T1 and T3 treatments was
significantly higher than that of the contrast.The early stage yield and total yield of T1 and T2 treatments were
all significantly higher than that of the contrast.T1 treatment was the best for VC,titratable acid,soluble
sugar and lycopene.Synthesizing yield,quality,temperature,humidity and light suitability inside of the
large-span outer covered greenhouse,T1 treatment has smaller planting risk and is a more suitable planting
pattern.
