Studies on Wide Trench Narrow Ridge Cultivation Model of Protected Tomato in Southern Zhejiang Based on Integration of Agricultural Machinery and Agronomy
Abstract：In order to improve the mechanization level and management efficiency of protected tomato in southern Zhejiang region and explore the cultivation model of integrating agricultural machinery with agronomy，this experiment changed the traditional wide ridge narrow trench cultivation model（the upper bottom width is 90 cm， lower bottom width is 110 cm，and trench width is 40 cm）to the wide trench narrow ridge cultivation model（the upper bottom width is 60 cm，lower bottom width is 80 cm，and trench width is 90 cm）；and compared the relevant indexes of tomato plant growth，yield，quality and labor used amount，etc. of these 2 models．The results showed that compared with the traditional wide ridge narrow trench model，the wide trench narrow ridge model had no significant effect on vegetative growth，single fruit weight and single plant yield of tomato，but when plant space was 35 cm the yield，high-quality fruit rate and high-quality fruit yield were all significantly higher than those of the control．There were no significant differences in contents of moisture，soluble solids，VC，total sugar，total acid and sugar-acid ratio with those of the control．The wide trench narrow ridge model could save 54.187 5 used labor amount comparing to the traditional cultivation model．In southern Zhejiang region，the wide trench narrow ridge model for protected tomato could adopt the double lines cultivation model with 35 cm plant space and 28 500 plants·hm-2，so as to improve labor efficiency
and increase yield.
