试验于1983—84年在临沭县曹村果园进行,供试品种为国光。果园土壤沙壤,土肥水管理水平一般。试验采用裂区设计,单株区组,重复四次。83年设三个处理,即花后立即行摘心、花后十天摘心及对照。84年为四个处理,即花后立即摘心、花后一周摘心、花后两周摘心及对照。摘心长度均为把付梢顶部嫩叶摘去。待生理落果后调查座果率、测量果实纵径,采收后测量果形指数。试验结果证明: 一、花后十天内摘心可促进座果,提高
Test in 1983-84 in Linshu Cao Village Orchard, the test varieties for the country light. Soil orchard soil silt, soil fertilizer and water management level in general. The experimental design using split zone, single plant block, repeated four times. In 1983, there were three treatments, that is, topping the flowers immediately after anthesis, and topping and contrasting ten days after anthesis. 84 years for the four treatment, that is, after the topping in the flower immediately, after a week topping after the flower, two weeks after the flower topping and control. Topping the length of the tips are to pick the tip of young leaves removed. Pest physiological fruit to be investigated after the fruit rate, measuring the fruit longitudinal diameter, fruit shape index after harvesting. Test results show that: First, within ten days after the flower topping can promote fruit, improve
