Soil plowing depth is very important in improving soil quality and promoting of crop production system. The relationship between soil plowing depth and soil chemical properties and crop yield was analyzed. Soils were sampled from 20 watermelons, 19 muskmelons, and 22 squash farms of plastic film house. The results showed that the average soil plowing depth of watermelon, melon, and squash cultivated in the plastic film house were 22 cm, 21 cm, and 27 cm, respectively. when the soil depth of watermelon and squash was deepened to 31 cm (26 - 39 cm), the levels of nitrate ion (NO₃<sup>-</sup>), electrical conductivity (EC), and exchange cations (Ex. cations) decreased by 2 - 42% compared to 18 cm (14 - 24 cm). The concentration of NO₃<sup>-</sup>, EC, and Ex. Potassium (Ex. K) of muskmelon cultivation with soil depth of 28 cm (26 - 36 cm) tended to decrease by 5 - 39% compared to 17 cm (14 - 22 cm). The yield of watermelon, muskmelon, and squash were increased by 6 - 22% when the soil plowing depth was 39 cm compared to 25 cm. The contribution of plowing depth to yield of 3 crops was highly significant at 13.1 - 28.2%. Therefore, deep tillage is necessary to improve soil health and increase yield of watermelon, muskmelon, and squash under plastic film house
