适龄不结果苹果树主要是由于管理粗放,使树体生长过旺或者过弱而造成,严重影响了果树的发展,甚至威胁着果树的存亡。为此,从1999年开始,在四川省旺苍县三江镇83.3 hm2中、晚熟6年生不结果果园内采用多种促花、栽培措施进行试验,结果至2000年,促花、栽培综合管理的试验区就有86.40%的植物开花结果,平均每667 m2产量1 078.00 kg,其他实验区只零星挂果,2000年5月开始对所有实验区改用促花、栽培综合管理的试验方法,至2001年除对照区常规管理仍未开花结果外,各实验区均全部投产而且日产量达每667 m21526.00 kg,取得了明显的经济效益。
Appropriate age does not result Apple tree is mainly due to extensive management, so that the growth of the tree over or under the weak, resulting in serious impact on the development of fruit trees, and even threatened the survival of fruit trees. To this end, since 1999, 83.3 hm2 in Sanjiang Town, Wangcang County, Sichuan Province, the results of six years of late maturity orchards within the orchard using a variety of flowers and cultivars to test, the results of 2000, promoting flowers, integrated management of cultivation There were 86.40% of the plants in the experimental area, with an average yield of 1 078.00 kg per 667 m2. Other experimental areas only had sporadic fructification. In May 2000, all the experimental areas were switched to the experimental method of promoting flowers and integrated management of cultivation until 2001 In addition to the conventional control of the area has not yet flowering results, all experimental areas are all put into operation and the daily output of 667 m21526.00 kg, achieved significant economic benefits.
