不同施肥量对中华猕猴桃果实生长发育规律的影响

Influences of Different Fertilizer on the Growth and Development of Actinidia chinensis Planch

研究了不同施肥量对中华猕猴桃果实生长发育规律的影响。结果表明,不同处理对贵州猕猴桃果实纵、横径的生长量年变化规律有一定的影响,总趋势是开始生长较快,然后渐慢,以后进入缓慢生长期,最后随果实成熟期的到来,其生长曲线渐趋平稳;从整个曲线看,果实纵、横径生长出现两个明显的生长高峰期,均呈逐渐上升的单曲线,不同处理对贵州猕猴桃果实纵、横径的生长在年生长发育过程中的生长高峰期的次数没有影响,但对生长曲线的起伏有一定的影响;不同处理对贵州猕猴桃果实纵、横径的净增长量、纵、横径净生长量高峰出现的时间和净生长量曲线起伏程度的年变化规律有一定的影响,但不影响纵、横径净生长量高峰的次数;不同处理对果实纵、横径的影响效果最好的是单株施用农老大复合肥0.30kg的处理,其次是单株施0.15kg的处理,效果较差的是单株施0.45kg的处理和对照。

The influences of different fertilizers on the growth and development of Actinidia chinensis Planch were studied.The results showed that：①the different treatment had no effect on the number of peak in the process of growth,but had certain effect on the undulation of growth curve;②the different treatment had some influences on the net increase of fruit width and the diameter,the undulation of the growth curve,and had not influence on the number and size growth peak;③ among the different treatments,the effect of treatment of compound fertilizer 0.30kg per plant was the best,followed by the treatment of compound fertilizer 0.15kg per plant.
