施用苹果增产菌具有增加产量、提高果实品质等功能。为了解苹果增产菌的最佳施用时期和用量,我们于1991年在宿县夹沟乡黄町村苹果园中进行了喷布苹果增产菌试验。试材为17年生的金冠苹果品种,行株距为7m×5m。试验设3个处理,处理1为萌芽前、开花期、幼果期(5月15日)、果实膨大前期(6月1日)和果实膨大中期(7月20日)5个时期分别每株喷施3、3、5、5、5g苹果增产菌;处理2为幼果期、果实膨大前期和果实膨大中期3个时期分别每株喷施5、5、5g苹果增产菌;处理3即对照为以上5个时期分别喷施清水。根据树体大小将所用增产菌按每株加无污染清水3-10 kg喷施(萌芽前和开花期分别加水3 kg和5 kg,其余均加水10kg)。3株小区,3次重复。苹果增产菌为北京农业大学试验厂生产。试验结果表明,处理1的花朵坐果率(61.2％)低
Application of apple increased production of bacteria with increased yield, improve fruit quality and other functions. In order to understand the optimal application period and amount of the apple increasing bacteria, we carried out the experiment of spraying the apple increasing bacteria in Huangmaocun apple orchard in Jiagou Township, Suxian in 1991. Test material for the 17-year-old Golden Delicious apple varieties, row spacing of 7m × 5m. The experiment was divided into three treatments: treatment 1: pre-emergence, flowering, young fruit (May 15), early fruit enlargement (June 1) and mid-fruit enlargement (July 20) Spraying 3,3,5,5,5 g apple to increase the production of bacteria; treatment 2 for the young fruit period, the fruit pre-swelling and mid-fruit enlargement were sprayed 5,5,5 g of apple per plant growth of bacteria; treatment 3 that control For the above five periods were sprayed with water. According to the size of the tree, the yield-producing bacteria should be sprayed with 3-10 kg of clean water without pollution (3 kg and 5 kg respectively before budding and anthesis, and the rest 10 kg water). 3 plants, 3 replicates. Apple increased production of bacteria for the Beijing Agricultural University pilot plant production. The results showed that the flower setting rate of treatment 1 was low (61.2%)
