Other claims from this paper (16)
- Intervention effect Closed hydroponic cultivation increased the average fruit weight of netted melon by 71.4 g relative to open cultivation, a statistically significant difference.
- Intervention effect Closed hydroponic cultivation increased the fruit width of netted melon by 0.2 cm relative to open cultivation, a statistically significant difference.
- Intervention effect Closed hydroponic cultivation did not change the average sugar content of the fruit flesh of netted melon relative to open cultivation.
- Intervention effect Closed hydroponic cultivation did not change the height of netted melon relative to open cultivation.
- Intervention effect Closed hydroponic cultivation increased the productivity of irrigation by 7.6 kg/ton compared with open cultivation.
- Intervention effect Closed hydroponic cultivation decreased water resources used per fruit by 31.6% compared with open cultivation.
- Association Closed cultivation saved about 59% of nitrogen (N) over the whole cultivation period.
- Association Closed cultivation saved about 55% of potassium (K) over the whole cultivation period.
- Association Closed cultivation saved about 83% of calcium (Ca) over the whole cultivation period.
- Association Closed cultivation saved about 76% of magnesium (Mg) over the whole cultivation period.
- Association Closed cultivation saved about 87% of sulfur (S) over the whole cultivation period.
- Association Reusing the drainage raised the NO3- ratio in the drainage, up to a maximum of 9.6.
- Association Reusing the drainage raised the Ca2+ ratio in the drainage, up to a maximum of 9.1%.
- Association Reusing the drainage gradually decreased the ratios of the other ions in the drainage.
- Mechanism The authors conjecture that the change in the macronutrient ratio of the irrigation raised fruit weight by changing the nutrient uptake concentrations of the crop.
- Recommendation The authors conclude that closed hydroponic cultivation can effectively optimize the use of water and fertilizer in melon cultivation while maintaining excellent fruit quality.
