1、土肥水管理。根据树龄不同,产量不同,土壤肥力不同,确定施肥量。一般按照1千克果2千克肥追施基肥,5-6年生的树氮、磷、钾肥比例为2:2:1,株施基肥30千克,追尿素1千克,过磷酸钙2千克,硫酸钾0.4千克;大树氮、磷、钾肥比例为1:0.5:1,株施有基肥75千克,追施尿素2.5千克,磷酸二氢钾2.5千克,喷施500倍惠满丰。浇水4—5次,花前水、花后水、幼果膨大水、封冻水,雨季天气过旱再补浇1-2次,水量浇透为宜;浇水后中耕除草,保持土壤疏松;免耕果园适时喷除草剂。
1, soil and fertilizer water management. According to different ages, different yields, different soil fertility, to determine the amount of fertilizer. Generally follow the 1 kg of fruit 2 kilograms of fertilizer to chase the base fertilizer, 5-6 year-old tree nitrogen, phosphorus and potassium ratio of 2: 2: 1, plant base fertilizer 30 kg, urea recovery 1 kg, 2 kg of superphosphate, potassium sulfate 0.4 kg; tree nitrogen, phosphorus and potassium ratio of 1: 0.5: 1, the plant has a base fertilizer 75 kg, topdressing urea 2.5 kg, potassium dihydrogen phosphate 2.5 kg, spraying 500 times benefit Manfeng. Water 4-5 times, before flowering, after flowering, young fruit enlargement of water, frozen water, rainy season and then make up drought irrigation 1-2 times, watering appropriate; irrigation after weeding, keep the soil loose ; No-tilled orchard timely spray herbicide.
