Abstract：The cucumber was selected to study different deep plowing on the growth and yield. In the early flowering stage, the prophase, metaphase and anaphase to determined growth and yield indexes by plowing 30, 50, 80 cm. The results showed that deep plowing could improve leaf number, leaf area index, plant height and stem diameter in middle and late fruiting stage, the photosynthetic rate in early,middle and late fruiting stage, the coefficient and the root volume in middle and late fruiting stage, 20-40 cm root percentage and yield. In middle and late fruiting stage, effect of deep plowing 50 cm on plant growth and yield increasing is the most significant. Significantly increased the number of leaves by 12.20% and 38.82%, leaf area index by 16.67%and 30.65%, plant height by 22.98%and 19.63%, stem diameter by 10.00%and 6.52%, net photosynthetic rate by 50.33%, intercellular carbon dioxide concentration by 30.47% and 29.88, transpiration rate by 25.97%and 31.35%, root coefficients by 48.01%and 35.30%. 50 cm deep plowing increased 35.29%root in 20-40 cm soil layer, 23.05% for cucumber yield per plant, 17.63% for the total yield. Therefore, 50 cm deep plowing has great value in greenhouse cucumber cultivation.
