1 材料与方法1.1 材料试验选择在新疆昌吉州红地球葡萄高效示范园,4～5年生树,生长健壮,当年负载量中等。株行距1m×5m,管理水平较高。供试纸袋:①转光膜袋(北京市瑞得来转光膜厂),白色,规格30cm×20cm。②木浆纸袋(河北省晋州市纸袋厂),浅白色,大袋规格37cm×26cm、小袋33cm×24cm。③自制报纸袋,规格40cm×26cm。1.2 方法设计两个试验方案。1)选树势、树龄、负载量、管理水平一致的红地球葡萄80株,分4组,每组20株,每株选大小基本一致的果穗8个,其中2穗对照,另6穗分别套上述3种不同纸袋(每2穗套同一纸袋)。统一
1 Materials and Methods 1.1 Materials Test Selection Hongjiacaojiaoye, Changji, Xinjiang efficient demonstration garden, 4 to 5-year-old tree, robust growth, when the load was medium. Plant spacing 1m × 5m, a higher level of management. Test paper bags: ① transfer film bag (Beijing Rui to light film factory), white, size 30cm × 20cm. ② pulp paper bag (paper bag factory in Jinzhou City, Hebei Province), light white, big size 37cm × 26cm, pouch 33cm × 24cm. ③ homemade newspaper bag, size 40cm × 26cm. 1.2 Methods Design two experimental programs. 1) 80 red globe grapes with the same tree age, loading capacity and management level were divided into 4 groups with 20 plants in each group, 8 ears of the same size were selected for each plant, of which 2 ears were control and the other 6 ears were Set of the above three different paper bags (two sets of the same paper bag).
