Preliminary report on the reagent test for preserving flowers and fruits of pear
Abstract：A continuously two-year reagent test for preserving pear flowers and fruits was conducted by using frequently-used hormones and micro-element fertilizers.The results showed that the hormones such as 2,4-D,GA and KT-30 could improve the fruit setting rate.However,pear trees were sensitive to 2,4-D and it was difficult to handle a suitable concentration in productive process.Two concentrations(66.7 mg/kg and 200.0 mg/kg) of GA have unfavorable effect on fruit quality and were not suitable to be further extended.Both too low(5.0 mg/kg)or too high(20.0 mg/kg) concentrations of KT-30 were not ideal to improve the fruit setting rate.Concentration of 10.0 mg/kg was helpful for the fruit setting rate and has no unhealthy effect on pear plants as well as less effect on fruit quality.Micro-element fertilizers such as Plant Dynamic 2003,OPAL fertilizer and multi-Elements and high efficient compound fertilizer could improve the fruit setting rate in certain degree and be beneficial for improving fruit quality and plant growth.The above micro-element fertilizers could be popularized in the productive practice.
