果树专用反光膜使用方法:
Method of using special reflective film for fruit trees:
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 began to lay reflective film in the early and middle of September, and combined with bagging, fruit rotation, leaf thinning and other supporting technologies to produce all-red fruit.
1、经生产试验,以下两种铺膜方法较好
1. Through production test, the following two 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 on both sides of the tree. The reflective film is perpendicular to the outer edge of the tree crown, and the ground is laid flat. Bricks and stones are used to press down the edge. This method is suitable for dwarfing and dense plantation.
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。
(2) In order to save reflective film in arborization and sparse plantation garden, we can lay the reflective film according to the size of the tree crown, and make the ground surface under the tree crown to a certain gradient, and cut the reflective film according to the size of the tree crown and lay it compactly.
2、在铺膜过程中应注意的问题
2. Problems to be noticed in 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) In dense planting orchards and orchards with poor illumination conditions, measures such as thinning leaves and fruits and thinning branches should be taken to increase illumination and improve reflectivity.
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) For orchards with better inter-row light transmission, after laying reflective film, attention should be paid to avoid sunburn. The reflective film can be slightly creased to make the reflective light diffuse and reverse, and

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, the reflective film should be laid in time, and the film surface should be kept clean to give full play to its reflective effect.
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 film, wipe it clean, dry it on the board and store it in a cool, ventilated and dry place for next year's use.
