材料和方法试材为一致的一年生 Wagner 氏岔(直径265mm、深300mm)栽兴津早生温柑/枳树,盆中于1986年、1987年3月下旬用花冈岩土和茎皮堆(2:1)肥充满。直到试验开始时,试材均置于大田。通过将盆载桔树安置在可与其分离的水池(640×440×380mm)装置里,用加热或冷却的办法来控制土温。每个水池表面用泡沫聚苯乙烯板包被,只为树干和环流管留一小孔(Poerwanto,R.1987)。试验一般所有树保持在25℃恒定气温中。将试材分为三组,每一组分别给予15、20、25
Materials and methods The test material was a uniform annual Wagner switch (265 mm in diameter and 300 mm in depth) planted early morning temperature citrus / trifoliate orange, pot in 1986, late March 1987 with the flower soil rock and stem bark ( 2: 1) fat is full. Until the beginning of the test, the test materials are placed in Daejeon. The soil temperature is controlled by heating or cooling by placing the potted orange tree in a pool (640 × 440 × 380mm) unit separable from it. Each pool surface is covered with Styrofoam plates, leaving only a small hole for the trunk and loop (Poerwanto, R. 1987). Test All trees are generally kept at a constant temperature of 25 ° C. The test material is divided into three groups, each group were given 15,20,25
