在以色列西加里利地区,于萌芽期和座果期进行了猕猴桃疏除试验。其目的是:1.确定疏除的最佳生理期,2.获得最佳的果个和产量;3.确定单株数和翌年产量的相互关系。结果表明,单株果数和单果重或翌年产量呈负相关。萌芽期比座果后疏除的果个大,随单株负载量的降低,两种疏除期的差别越小。如单果重不小于70克,在萌芽期疏除每株需留1700个果,座果期疏除每株应留1400个果。未用氨氰(Alzodef)打破休眠的植株与喷施氨氰的植株相比,前者的结果致不及后者的一半。
Kiwi thinning tests were conducted during the germination and fruit setting stages in the Western Kalijal region of Israel. Its purpose is to: 1. Determine the best physiological period of thinning, 2. To obtain the best fruit and yield; 3. Determine the relationship between the number of single plants and the following year’s production. The results showed that there was a negative correlation between the number of fruit per plant and the weight of single fruit or the yield of the following year. In the budding stage, the fruit size was larger than that in the fruit thinning stage. With the decrease of the plant load, the difference between the two sparse periods was smaller. If the fruit weight is not less than 70 grams, in the budding period to leave 1,700 per plant to leave fruit, fruit thinning should leave 1400 per plant fruit. The plants that did not break dormancy with ammonia (Alzodef) did not produce as much half as the plants sprayed with ammonia cyanide.
