栗树良种丰产配套栽培技术的研究

Series of high yield planting techniques of fine varieties of chestnut trees

对新选育出的辽栗10号、辽栗15号、辽栗23号3个栗树新品种,应用良种、施肥、修剪、授粉、合理密植等丰产栽培技术进行中试推广,结果表明,以2年生实生苗嫁接建园,初植密度1m×1m,嫁接第4年,密度调整为2m×2m,在不同立地条件选用合适的良种组合,可以达到结实早、丰产的效果。

Medium experiment popularization regarding such high yield cultivation techniques as application of fine varieties, fertilization, trimming, pollination, rational densely planting was conducted for 3 chestnut species newly selected, namely, No 10 LiaoLi, No 15 LiaoLi and No 23 LiaoLi. The results showed that establishing seed orchard by using 2a seedlings, initial density 1m×1m and adjusted to 2m×2m at 4th year of grafting, early fruiting and high yield effects could be achieved by choosing suitable combinations of fine varieties under different site conditions.
