四川盆地柑桔秋季地膜覆盖效果初报

柑桔是典型的热带常绿阔叶果树。四川盆地的“暖冬”气候条件,为柑桔越冬避冻提供了良好的生态环境;但是四川盆地夏季积温相对偏少,特别是秋季阴霾寡照、气温偏低、秋雨过多的天气,导致四川盆地柑桔成熟度偏低、食味偏酸、品质下降。为了提高四川柑桔的市场竞争能力,作者在盆中浅丘区做了柑桔秋季地膜覆盖试验。结果表明,柑桔非生理落果减少,平均增产5%～32.6%,成熟期提前4～11天,果实含糖量提高2.6%～23.9%,酸度下降1%～19.8%,品质、风味均有所改善。

Preliminary Study on the Efficiency of Autumn Orange Trees Covered by Plastic Film in Sichuan Basin

Based on the test of Autumn orange trees covered by plastic film,this paper studied the relations between the orange sugariness,acidness and the yield with the meteorological conditions.It shows that the orange mature priod is shortened,the production is increased and the orange quality is en- hanced.
