秋子梨是梨中形成花芽较强的品种,大年时,花量达70％以上,任其自然结果,下年就会形成小年。调节的办法是蔬花疏果,而人工疏花疏果用工量太大,效率低。为了解决秋子梨疏果难的问题,去年春,在省果树所的指导下,我们在北镇富屯公社龙岗子大队进行了药剂疏果试验,收到了较好效果。 秋子梨盛花后7天喷布1,500ppm西维因,达到淋湿状态,对照树喷水。喷药后调查,花序座果率比对照减少3.4％,花序平均座果数降低0.85个。采收后,一级果率比对照树提高13.1％。
Autumn pear is the formation of pears strong flower bud varieties, the New Year, spend up to 70%, let its natural result, the next year will form a small year. The method of adjustment is thinning fruit and flower, but the amount of artificial flower thinning fruit is too large, low efficiency. In order to solve the problem of fruit thinning of autumn pear, last spring, under the guidance of the Provincial Fruit Tree, we conducted the drug thinning test in Longgangzi Brigade of Tuen Mun Commune in Beichen Town and received good results. Autumn pear spray 7,500 days after the flower sprinkling 1,500ppm cineral, reached the wet state, the control tree water. After spraying the investigation, inflorescence fruit rate decreased 3.4% compared with the control, the average number of inflorescence fruit reduced 0.85. After harvesting, the first-level fruit rate increased by 13.1% over the control tree.
