Other claims from this paper (17)
- Observation Dry matter accumulation and nutrient uptake of cucumber had similar S-curve characteristics.
- Observation The fruiting stage was the critical stage for dry matter accumulation and nutrient uptake.
- Intervention effect Root dry matter was not significantly affected by the different water and nitrogen application patterns.
- Intervention effect Optimized water and nitrogen application rates improved dry matter accumulation and its ratio to total dry matter, especially in fruit.
- Intervention effect Optimized water and nitrogen application rates decreased the root to shoot ratio.
- Observation Cucumber absorbed 396 to 490 kg/ha N to attain a yield of 150 to 200 t/ha.
- Observation Cucumber absorbed 93 to 127 kg/ha P.
- Observation Cucumber absorbed 516 to 529 kg/ha K.
- Observation Nutrient uptake followed the order K, N, P to attain a cucumber yield of 150 to 200 t/ha.
- Observation The N:P:K ratio of nutrient uptake was 1:0.21:1.17 under optimized water and nitrogen application rates.
- Intervention effect Nitrogen fertilization improved dry matter and nitrogen uptake of cucumber.
- Intervention effect Reduced water supply improved dry matter and nitrogen uptake of cucumber.
- Intervention effect Compared with conventional supply, optimized water and nitrogen application improved dry matter accumulation, nitrogen uptake and the ratio of nitrogen in fruit.
- Intervention effect The ratios of P and K to N were increased by the optimized treatment.
- Intervention effect The uptake of P and K was decreased by the optimized treatment.
- Intervention effect Optimized water and nitrogen supply improved nitrogen use efficiency, partial nitrogen production efficiency and water use efficiency.
- Intervention effect Optimized water and nitrogen supply decreased luxury uptake of phosphorus and potassium.
