Can be once every quarter, each time per acre (12-15 trees) 10-20KG. Two adult trees: adult tree hi high temperature and humidity, non-resistant non-drought resistance to low temperature (critical point of 15 degrees), prefer potassium, before the flowering recommended 1-2 times high nitrogen fertilizer 30-10-10 ( 1:500 ratio foliar spray) to promote flower bud differentiation, fruit to high potassium fertilizer, especially like potassiu...
