袋控缓释肥在北京山坡地桃园的应用效果初探

Application of bag controlled-release fertilizer in hillside peach orchard of Beijing

以6年生’华玉’桃树为试材,设置3个处理:习惯施肥处理、等价袋控缓释肥处理、推荐袋控缓释肥处理,比较了北京市山坡地桃园中3种施肥处理对桃果实产量、品质和树体生长的影响。结果表明:施用等价袋控缓释肥,比习惯施肥减少2/3的肥量,二者产量无显著差异;施用目标产量的推荐袋控缓释肥比习惯施肥成本降低了36.5%;施用袋控缓释肥,施肥次数比习惯施肥减少2次,省工节肥。建议在类似果园推广推荐袋控缓释肥。

Using 6-year-old'Huayu'peach tree as test material,three treatments were set up:conventional fertilization treatment,equivalent bag controlled slow-release fertilizer treatment,and recommended bag controlled slow-release fertilizer treatment.The effects of three fertilization treatments on the yield,quality and growth of peach fruit were compared in the peach orchard of hillside in Beijing.The results showed that the application of equivalent bag controlled slow-release fertilizer reduced two-thirds of the amount of fertilizer compared with the conventional fertilization,and there was no significant difference in the yield between the two;the recommended bag controlled slow-release fertilizer with the target yield reduced 36.5%of the cost compared with the conventional fertilization;the application of bag controlled slow-release fertilizer reduced the frequency of fertilization by 2 times compared with the conventional fertilization,saving labor and fertilizer.
