Experimental study on mechanized cultivation mode of facility tomato in Sichuan Basin
In view of the problems of the existing wide-narrow double-row cultivation mode for facility tomato production in the Sichuan Basin,the aisles will be narrow in the middle and later stages of planting,which is not conducive to mechanized operation and low management efficiency.The premise is that under the condition of the same cultivation density in the multi-span plastic film greenhouse in Pengzhou City,Chengdu,the comparison experiment of adjusting the row spacing of tomato cultivation is carried out.The experiment is designed for 3 treatments,which are T1 plant spacing 0.34 m,wide row spacing 1.6 m;T2 plant spacing is 0.40 m and wide row spacing is 1.3 m;The spacing of T3 plants is 0.45 m,and the wide row spacing is 1.11 m and the light conditions of the plant community,plant growth,yield and quality of different treatments are measured.The results show that enlarging the wide row spacing and reducing the plant spacing can significantly increase the photosynthetically effective radiation intensity in the middle and lower parts of the planting row and the light duration of the whole plant,and reduce the photosynthetically effective radiation intensity inside the planting row.From the inside and outside of the planting row,the photosynthetically effective radiation intensity of the tomato community is improved.Enlarging the wide row spacing and reducing the plant spacing will increase the leaf biomass of the tomato plant,but the stem diameter and stem diameter are increased.Stem length was not significantly affected.The single fruit weight of different treatments was 0.18-0.19 kg,and the yield was 101 625-103 140 kg/hm2,with no significant difference.The ratio of sugar to acid of tomato fruit was 6.6 with no significant difference.Based on the above results,it can be seen that the plant spacing of 0.34 m,the narrow row spacing of 0.4 m,the wide row spacing of 1.6 m,and the cultivation mode of 29 430 plants per hectare can be used for facility tomato plants in the Sichuan Basin.On the premise of not affecting the output and quality,the operation efficiency is improved and the production cost is reduced.
