一、肥水管理每年秋季每株成龄树沟施农家肥50-60公斤和氮肥1-2公斤,磷肥1-2公斤。一般沟深为25-35cm,沟宽40-50cm,把肥料撒入沟底掺土搅拌均匀,然后盖土。每年在开花前(5月下旬)和幼果膨大期(7月上旬和8月上旬)各追施一次化肥。5月下旬株施尿素1-2公斤和过磷酸钙1.5-2公斤。7月上旬株施果树专用肥1.5-2公斤或磷酸二铵0.5-1公斤。8月上旬株施磷酸二铵0.5-1公斤或硫酸钾0.5-1公斤。5月中下旬叶面喷布350-400倍尿素液一次,7-8月份叶面喷布0.3%磷酸二氢钾2-3次,一般半个月左右喷一次。
First, fertilizer and water management Each autumn tree planting facilities 50-60 kilograms of farm manure and 1-2 kilograms of nitrogen, phosphate 1-2 kilograms. General ditch deep 25-35cm, ditch width 40-50cm, drenched into the ditch fertilizer mixed with soil, and then cover the soil. Each year before flowering (late May) and young fruit enlargement (early July and early August) each topdressing fertilizer. In late May strain of urea 1-2 kg and superphosphate 1.5-2 kg. Early July plant dedicated fruit trees 1.5-2 kg or 0.5-1 kg of diammonium phosphate. In early August strains of ammonium phosphate 0.5-1 kg or 0.5-1 kg of potassium sulfate. In mid to late May foliar spray 350-400 times a urea solution, July-August foliar spraying 0.3% potassium dihydrogen phosphate 2-3 times, usually spray about once a month.
