在5年滴灌研究期间,对果实产量和果汁品质进行了测定。灌溉处理以不灌溉为对照。设每株2个、4个滴嘴,1个、2个喷嘴处理;施肥处理以干肥为对照。设通过灌溉系统(滴灌施肥)分别供给15％、30％N和K处理结果表明:灌溉增加了39—64％的果实产量,超过对照;果实产量随各灌溉处理所及面积的增大而增加;灌溉和局部滴灌施肥处理,降低了果汁的可溶性固形物(白利糖度)和酸浓度;局部滴灌施肥处理对果实产量影响不太。滴灌或低容量灌溉作为佛州柑桔最流行的灌溉方式正在得到承认,因为该系统仅灌溉根系的一部分。成本相当低,且具有节水省能的潜力。通过灌溉系统供给肥料的滴灌施肥是滴灌方式的潜在优越性之一。而树下喷嘴系统,还具有防冻的可能性。据报道,砂质土上的柑桔果实产量,随滴灌处理所及的地表面积的增大而增加。本研究始于1978年,旨在评定不同的处理面积和滴灌比率对植株的影响。此外将局部滴灌施肥处理与干肥处理作一比较。本文总结了5年来的叶分析、果实产量和果实品质的数据。 During the five-year drip irrigation study, fruit yield and fruit quality were determined. Irrigation was compared to non-irrigation. Set 2 per plant, 4 drops, 1, 2 nozzles; fertilization treatment with dry fertilizer as a control. Supplying 15%, 30% N and K by irrigation system (drip fertilization), respectively, showed that the irrigation increased the fruit yield by 39-64% over the control and the fruit yield increased with each irrigation treatment and the area increased Irrigation and local drip fertilization reduced the soluble solids (Brix) and acid concentration of fruit juice. Local drip fertilization did not affect fruit yield significantly. Drip irrigation or low volume irrigation is being recognized as the most popular irrigation method for Florida citrus because it only irrigates part of the root system. The cost is quite low and has the potential to save energy and save energy. Drip irrigation by supplying fertilizers through irrigation systems is one of the potential benefits of drip irrigation. The tree nozzle system, but also with the possibility of antifreeze. It is reported that citrus fruit production on sandy soil increases with increasing surface area of ​​drip irrigation. This study began in 1978 to assess the effects of different treatment areas and drip irrigation rates on plants. In addition, local drip fertilization treatment and dry fertilizer treatment for a comparison. This article summarizes leaf analysis, fruit yield, and fruit quality data over the past five years.
