Papaya plants grow fast, early-maturing varieties, 45 to 50 days after planting to start budding, flowering annual results, it required a large number of trace elements and must be an adequate supply to meet normal growth and flowering. Foreign studies have shown that the annual production of fresh nutrient entrained nitrogen 1,000,000 kg 112 kg, 9.9 kg phosphorus, potassium 178.5 kg, 9.43 kg calcium, magnesium 40.71 kg, 0.161 kg of boron, iron 0.1909 kg, 0.1173 kg zinc, molybdenum, 0.0025 kg , copper 0.0276 kg, manganese 0.0299 kg, sodium 3.0889 kg. The ratio of nitrogen, phosphorus, potassium, calcium and magnesium is 1 : 0.09 : 1.59 : 0.08 : 0.36 . Potassium and boron are scarce in the soil of most orchards in Hainan. Therefore, potassium and boron fertilizers should be applied in production. The optimum fertilization ratio of papaya balanced fertilization test is: the ratio of nitrogen, phosphorus and potassium in the whole annual growth period (from January to December ) is 1 : 0.9 : 1.1 , and the ratio of nitrogen, phosphorus and potassium in the vegetative growth period is 1 : 1 : 0.5 (including base fertilizer), the ratio of nitrogen, phosphorus and potassium in reproductive growth period is 1 : 0.8 : 1.5 . Nitrogen, phosphorus and potassium are mainly absorbed from the soil by the root system. The amount of nitrogen, phosphorus and potassium needs to be large enough. It is necessary to meet the needs of fast-growing and high-quality by rational fertilization. The boron fertilizer is satisfied by spraying on the soil and foliar surface .
How to determine the amount of fertilization, fertilization period and method in each growing season, in principle: the application of thin fertilizer in the seedling stage, re- application in the bud stage, young fruit stage and fruit stage . Mainly based on farmyard manure, supplemented by chemical fertilizers, combined with organic fertilizers and inorganic fertilizers. In production, organic fertilizer is used as the base fertilizer, organic water and fertilizer is used as top dressing, and chemical fertilizer is used as fertilizer.
Fertilization method: foliar fertilizer spraying, chemical fertilizer shallow ditch application or spreading, the general saplings are applied by the ring ditch, the ditch is 10 cm deep and 15 cm wide , and the soil is applied after the drip line; the three-month-old strong tree is in Both sides of the plant were digging in shallow trenches along the drip line to fertilize the soil. Do not burn the stems or leaves when applying fertilizer. Usually the dry season against irrigated facilities, rainy or applicator after watering sprinkler, the effect is better. The cake fertilizer or farmyard manure in organic fertilizer needs to be applied after 20 days of ripening .
