夏季是板栗结果枝梢生长的旺盛期,同时又是板栗根系生长的第一个高峰,需要大量养分。如此期的树体养分不足,特别是硼肥缺乏,板栗空苞增多,产量低。要使板栗降低空苞率必须施好夏肥。其技术要点如下:一是根外追肥。此法在夏季或整个生长期均可进行。可采用0.3%—0.4%
Summer is the vigorous growth of chestnut results shoots, but also the first peak of chestnut root growth, requiring a lot of nutrients. This period of insufficient tree nutrients, especially the lack of boron, empty chestnut hollow increase, low yield. To reduce chestnut empty peanut rate must be applied to summer fertilizer.
