1, Miao. At present, seed propagation is widely used in Lushui County. The method is to take out the seeds after the fruit matures in autumn, without washing the seeds after taking them out. Be careful not to expose the seeds to the sun. Sow the seeds in autumn after picking them, or store them in sand at low temperature until the next spring.
2. Planting. Planting in autumn, spring or before the rainy season, the density is about 40 plants per mu, and it is also planned to plant 60-80 plants per mu. In order to blossom and bear fruit in advance and maintain the excellent characteristics of the mother tree, it is best to adopt cutting and grafting propagation. Then spray a new high-fat film to shorten the suspension period.
3. Soil, fertilizer and water management. Papaya has strong adaptability, but it still needs careful management to achieve high and stable yield. Peas, soybeans, potatoes, etc. Intercropping can be done in young trees. In order to prevent soil erosion, the number of intertillage on steep slopes is less. Every autumn, after fruit harvesting, ditch and apply base fertilizer (farm manure plus appropriate amount of phosphorus and potassium fertilizer). In the spring of the following year, topdressing was carried out again in the young fruit stage with backward flowers, with potassium fertilizer as the main fertilizer and phosphorus and potassium fertilizer as the supplement. In spring, the top dressing during fruit expansion is mainly potassium fertilizer and nitrogen fertilizer.
4, plastic trimming. The pruning method of young trees is: after the young trees are planted, they are fixed, and the main branches and lateral branches are cultivated year by year to form the crown skeleton. In this way, when pruning trees, if the crown is too shady, some big branches can be thinned or retracted, and if there are many long upright branches on the crown, they can be cut off or shortened to dry as needed. Cut off dead branches, pests and diseases, and cross branches in the crown. The sprouting branches at the base of the big branches and the lower part of the trunk are generally not cut off, and a small number of positions can be left for crown regeneration. Secondly, put an anti-corrosion film on the trimming mouth to prevent water evaporation and nutrient consumption.
