摘要:
为筛选适宜早酥梨疏花疏果的化学药剂，选取六至七年生早酥梨为试材，研究在不同时期Ca+NAA、Ca+SNA、Ca+ Sevin、Ca +6-BA药剂处理对早酥梨果实坐果率和品质的影响。结果表明：在盛花期1次疏花+盛花后10 d疏果时Ca150倍液+SNA 40 mg?L-1表现最好，坐果率为32.04%。在初花期、盛花期2次疏花+盛花后10 d疏果时喷施Ca150倍液+Sevin 2.0 g?L-1药剂处理表现最好，坐果率为23.63%。
Abstract:
In order to screen out the suitable chemical treatment for Zaosu pear flowe and fruit thinning,we use 6-7 years old pear trees as test material to study the effects of Ca+NAA,Ca+SNA,Ca+Sevin and Ca+6-BA treatments at different stages on the fruit setting and quality.The results showed that the treatment 2(Ca 150 times+SNA 40 mg?L-1)was the best in the treatment of thinning flower at flowering stage and thinning fruits at 10 days after flowering stage,and the fruit set rate was 32.04%.In the early flowering stage,the treatment 7 of Ca 150 times+ Sevin 2.0 g?L-1 was the best in the treatment 2 times flower thinning at early flowering stage and flowering stage and thinning fruits at 10 days after flowering stage,and the fruit setting rate was 23.63%.
