苹果果实只有靠太阳光的直射才能着色
苹果果实只有靠太阳光的直射才能着色,果实着生部位不同,阳光不能充分照射苹果导致着色不均匀。果园通过铺反光膜,反射阳光,改善整个果园特别是下部及内膛光照条件,使果实尤其是果实不易着色的部位(如萼洼处)充分着色,增加全红果,改善果品外观。
Apple fruit can only be coloured by direct sunlight. The sun can not
fully irradiate apple, resulting in uneven coloring. The orchard
reflected the sunlight by laying the reflective film, improving the
whole orchard, especially the lower and inner light conditions, so that
the fruit, especially the part of the fruit which was not easy to be
coloured, was fully coloured, to increase the whole red fruit and to
improve the appearance of the fruit.
据测定,铺反光膜园内中下层(距地面 1.5m 以下)的光合有效反射量增加 4~10 倍。
According to the measurement, the effective reflection amount of the
middle lower layer (below 1.5m of the ground) in the reflective film
garden increased by 4~10 times.
2、反光膜及园地选择:
2, reflective film and garden choice:
①反光膜选择:果园使用的反光膜宜选用反光性能好、 防潮防氧化、 抗拉力强的复合型塑料镀铝箔膜,其反光率可达 60%~70%,一般每亩果园用反光膜350㎡~450㎡,可连续使用 1~3 年。
(1) reflective film selection: the reflective film used in orchard is
suitable for composite plastic aluminum foil coating with good
reflective performance, moisture proof and oxidation resistance and
strong tensile strength. The reflective rate can reach 60% to 70%, and
350 acres of reflective film is used for 1~3 years in a mu orchard.
②园地选择:应选择管理精细,透光率好的果园,一般行间要有 0.6m~1m 的作业带,有太阳直射光,管理粗放,树体高大,果园郁闭,透光差的果园,意义不大。
(2) garden choice: we should choose the orchard with fine management and
good transmittance. There should be 0.6m to 1m operating belts between
the lines, the direct sunlight, the extensive management, the tall tree
body, the orchard canopy and the poor transmittance of the orchard.
3、铺设方法:
3. The method of laying:
(1)铺膜时间。套袋园一般在摘除果袋3~5天后进行,具体时间,要根据不同地区不同品种的成熟时间而定,
(1) paving time. Bagging gardens are usually carried out 3~5 days after
the fruit bags are removed. The specific time is determined according to
the maturity time of different regions and varieties.
