摘  要：
采用负水头灌溉装置,通过调节装置的供水吸力值来持续稳定地控制栽培基质的湿度,供给不同浓度磷酸二氢钾(KH2PO4)营养液配方进行樱桃番茄基质栽培试验,研究营养液中不同磷酸二氢钾浓度对樱桃番茄株高、茎粗、产量、水肥利用效率和根系活力的影响。结果表明:在负水头供水控水技术条件下,适当提高营养液中磷酸二氢钾浓度,有利于增加樱桃番茄株高、茎粗,效果显著;同时可以提高果实产量、水分利用效率和N、K利用效率以及根系活力。负水头供给营养液樱桃番茄栽培生产中,2.5S处理即340mg·L-1的KH2PO4浓度可作为推荐用量。

摘  要：
A negative pressure water irrigation device was used to supply nutrient solution directly for cherry tomato(Lycopersicon esculentum var.cerasiforme).Setting water supply tension to control stable soil moisture regime,different nutrient solutions formulae with different potassium dihydrogen phosphate(KH2PO4)concentrations were designed to make cherry tomato substrate cultivation.Effects of nutrient solutions with different potassium dihydrogen phosphate concentrations on plant height,stem diameter,yield,water and fertilizer use efficiency and root activity of cherry tomato were investigated.The results indicated that under the condition of negative water supplying and controlling device,as the concentration of potassium dihydrogen phosphate in nutrient solution increased,the plant height,stem diameter of cherry tomato increased,the effects were significant.The fruit yield,water use efficiency,N and K utilization efficiency and root activity were increased at the same time.For cherry tomato production under solutions from negative pressure water irrigation device,340 mg·L-1 KH2PO4 concentration can be considered as suggested application rate in solutions.
