- 摘要:
- 为提高枇杷果果实品质与产量,针对北缘地区冬季风大冻害重的问题,研究平地枇杷园风障对枇杷果实冻害及品质的影响。结果表明:遮阳网与单膜防寒布的防冻效果明显,二者间无明显差异;添加副风障的防冻效果更为显著;随着与风障距离的增加,每花序果实数减少明显,5 m、25 m处理分别比50 m多3.32、1.43个;风障可提高果实可溶性固形物含量和产量。
- Abstract:
- In order to improve the quality and yield of loquat fruit,solve the freezing damage in Beiyuan area,we mainly research the effect of wind barriers on the anti-freezing,quality and yield of loquat.The results showed that sunshade and single film anti-cold cloth had obvious anti-freezing effect,and no evident difference.The secondary wind barrier had significant effect on freezing damage.With the distance extension to wind barrier,fruit number per inflorescence decreased significantly,5 m and 25 m treatments were more than 50 m for 3.32 and 1.43,respectively.Wind barrier could improve the content of soluble solid and yield.
