抑制金柑高温落果试验研究初报

Preliminary report of the experimental research on inhibiting kumquat fruit drop in high temperature

为探讨金柑高温落果原因和防治方法,开展抑制金柑高温落果试验。通过对气温情况进行调查,发现气温是导致落果的重要因素,继而进行了6组不同营养素和生长调节剂组合对比试验,结果显示:采用30mg/l 920+5mg/12,4-D+芸薹素2000倍、芸薹素2000倍+30mg/l 920+天牛膏和糖醇钙+聚合硼+天牛膏三个处理落果明显减少。表明生长素和营养素可以有效地减少由于高温导致的落果。

To investigate the causes and control method of kumquat fruit drop in high temperature ,to carry out high-temperature suppression kumquat fruit drop test. By to investigating the temperature,it is found that the temperature is an important factor leading to fruit drop, which inturn carried out to six groups of diiterent numems test.Results show： 30mg/1 920 ＋ 5mg/1 2, 4-D＋Brassinolide 2,000 times,brassinolide 2000 times＋ 30mg/1 920 ＋ Longhorned beetle cream and sugar alcohols liquid calcium ＋polymeric boron ＋ longhorned beetle cream proeessing signicantly reduced fruit drop. It is showed that auxin and nutrients can effectively reduce the fruit drop caused by high temperatures.
