特点: Characteristic: 1、促进果实着色:铺反光膜后,从地面向上反光,使下垂果实的顶部和背阴面都能受光,提高了树冠中下层和内膛的光照强度,从而促进果实全面着色。经测定,铺膜树的全株平均着色指数在50%~70%,未铺膜树则只达到26%~40%,平均着色指数提高25%~30%。树冠内膛和下层果实着色指数提高到43.8%~54.3%,全红果和着色面积达3/4以上的果子占全株果数的35%~69%。果实含糖量、重量增加据用手持糖度仪测定,铺膜树果实可溶性物质为13%左右,比对照树高1%~3%;单果重增加5.7~6.7克。 1, to promote fruit coloring: after the reflective film is laid, the light on the top and the back of the back of the drooping fruit can be reflected from the ground, which improves the light intensity of the lower and inner bore in the crown of the crown, thus promoting the full coloring of the fruit. The average coloring index of the whole plant was 50% to 70%, while the uncoated tree only reached 26% to 40%, and the average coloring index increased by 25% to 30%. The coloring index of inner and lower fruits increased to 43.8% to 54.3%, and that of all red fruits and coloring area of 3/4 or more accounted for 35% to 69% of the total fruit number. The increase of sugar content and weight of fruit was measured by a hand-held sugar meter. The soluble substance of the fruit of the paving tree was about 13%, 1% to 3% higher than that of the control tree, and the weight of single fruit increased by 5.7 to 6.7 grams. 2、有利于花芽分化:铺膜树叶片增厚,绿色加深,花芽饱满,为第二年的增产打好基础。 2, it is beneficial to flower bud differentiation: laying leaves, thickening leaves, deepening green, and full flower buds, laying a good foundation for increasing production in second years. 3、产出效益较高:若每亩果园每年投入反光膜成本为400元,产苹果2000公斤,则1公斤果品投入为0.2元,由于果子着色好,售价每公斤提高0.5~1.00元,可获利600~1000元/亩。 3, the efficiency of output is high: if the cost of reflecting film is 400 yuan per mu per year and 2000 kilograms of apple is produced, the 1 kilograms of fruit is invested to 0.2 yuan. As the fruit is coloured well, the price of the fruit is increased by 0.5 to 1 yuan per kilogram, and the profit is 600~1000 yuan per mu. 二、果树专用反光膜使用方法:(富士苹果为例) Two, the use of special reflective film for fruit trees: (Fuji Apple). 富士系等高档苹果在着色初期,一般在9月上中旬开始铺反光膜,结合套袋、转果、疏叶等配套技术,生产全红果。 Fuji and other high-grade apples in the early coloring period, generally in the middle of the September to begin to spread the reflective film, combined with bags, fruit, sparse leaves and other supporting techniques, the production of full red fruit. 1、经生产试验,以下两种铺膜方法较好 1, through the production test, the following two kinds of laying methods are better. ①将反光膜顺行铺在树下两边,反光膜与树冠外缘垂直,平铺地面,用砖、石等压住边缘,此方法适用矮化密植园。 (1) the reflective film is laid down on both sides of the tree, the reflective film is perpendicular to the outer edge of the tree crown, the ground is laid on the ground, and the edges are pressed with bricks and stones. This method is suitable for the dwarf dense planting garden. ②对乔化稀植园,为节省反光膜,可根据树冠大小进行铺设,将树冠下地表整地向内呈一定坡度,根据树冠大小剪下反光膜铺好压紧。 In order to save the reflective film, it can be laid according to the size of the crown, and the surface of the ground surface under the crown is inward, and the reflective film under the crown size is pressed tightly. 2、在铺膜过程中应注意的问题 2. Problems that should be paid attention to during the process of film laying ①密植园,光照条件差的果园,应采取疏叶转果、疏枝等措施,增加光照,提高反光率。 (1) close planting garden, light and poor orchard should take measures such as thinning the leaves, turning fruit and branched branches to increase light and improve the rate of reflection. ②对果树行间透光较好的果园,铺设反光膜后,应注意避免出现日烧,可将反光膜稍打点折皱,使反射光呈漫反向,避免反向光过于集中,烧伤果实。 (2) to the orchard with good light transmittance between the fruit trees, after laying the reflective film, we should pay attention to avoid the emergence of the sun burning, and can make the reflective film wrinkle slightly, make the reflection light diffuse reverse, avoid the reverse light too concentrated and burn the fruit. ③在果实着色初期,及时铺设反光膜,并注意保持膜面清洁,以充分发挥其反光作用。 3. In the early stage of fruit coloring, lay the reflective film in time, and pay attention to keep the membrane surface clean, so as to give full play to its reflective function. ④在撤膜时,将膜擦干净,凉干缠于板上,存入在阴凉、通风、干燥处待来年使用。 (4) when removing the membrane, wipe the membrane clean, dry and wrap it on the board, and store it in a cool, ventilated and dry place for next year. 总结:苹果摘袋后铺上反光膜,着色时间比原来缩短一倍以上,使苹果着色全面,色泽非常光亮鲜艳。 Conclusion: after the apple bag is removed, the reflective film is coated, and the coloring time is more than twice that of the original apple. The apple is colourful and bright.
