问:新栽的红富士苹果,结的果个小是什么原因? 答:红富士苹果属于大型果,在土、肥、水、修剪、疏花疏果、病虫害防治等综合技术都跟上去的条件下,单果重一般在200克以上。至于“果个小”的因素是多方面的。一是土壤瘠薄,肥、水条件差,管理粗放,树势弱,养分积累少。二是遇到春早年份,土壤保肥、保水能力差,浇不上水,势必影响果实的生长发育。如山东省的年降雨量 Q: What are the reasons for the newly planted Red Fuji apples? A: Red Fuji apples are large-scale fruits and they are kept in comprehensive technologies such as soil, fertilizer, water, pruning, thinning, thinning, pest control, etc. Conditions, single fruit weight is generally above 200 grams. As for the “small fruit” factors are many. First, soil infertility, fertilizer, water conditions are poor, extensive management, tree weak potential, nutrient accumulation less. Second, in the spring early years encountered, soil fertility, poor water retention capacity, pouring on the water, is bound to affect the fruit’s growth and development. Such as the annual rainfall in Shandong Province
