Baihe papaya quality technical requirements (1) variety. Local local papaya varieties. (2) Land conditions. At an altitude of 300 to 900 meters, the soil type is yellow brown soil, the soil layer thickness is more than 50 cm, the soil pH is 5.3 to 7.0, and the organic matter content is ≥1.0%. (3) Cultivation management. 1. Seedling breeding: seedling breeding. Seedlings are divided into autumn and spring sowing. Autumn sowing, from late October to early November. Spring sowing, from the beginning of March to the end of March. Choose well-developed, fully mature papaya fruit, take the seeds, clean them, dry them, and store them in a low-temperature dry place. Seeds sown in spring must be stratified by sand at low temperatures. Both spring and autumn can be used. When the seedling diameter is more than 0.5cm, it can be grafted. Spring grafting is carried out 20 days before the sprouting of the rootstock, using splicing, tongue or leather. After grafting, check the survival rate and make up. Cut the anvil in time, except for sprouting and loosening. 2. Planting: Planting time, autumn planting in the normal leaves of papaya trees until the land is frozen (mid-November to early December); spring planting is carried out before the soil is thawed to the saplings (from late February to mid-March). ≤900 plants per hectare. 3. Fertilization: It is mainly based on decomposed farmyard manure or crushed high-quality cake fertilizer, and assists in the use of chemical fertilizer (papaya special fertilizer). The application rate of decomposed farmyard manure is 37500-75000kg/ha, and the quality cake fertilizer is 2250-3750 kg/ha. 4. Plastic pruning: pruning is dominated by winter pruning, combined with winter pruning and summer pruning. The main task of winter shearing is to shorten the strong branches, to eliminate the dense branches, the weak branches and the diseased dead branches, and to slowly release the moderate branches. In summer, measures such as thinning, topping, twisting, thinning and thinning, and leaf thinning are used to adjust the tree potential, and the ventilation is light. 5.
