Cultivation method of Peruvian annua
As a characteristic fruit tree originating in tropical America, Peruvian annola has gradually attracted the attention of planting enthusiasts due to its unique fruit flavor. However, many people often encounter problems such as wilting plants and low fruit bearing rates during the cultivation process. In fact, as long as you grasp the five core elements, you can make this tropical treasure flourish in the courtyard. The soil ratio plan for basic maintenance points recommends using a mixed substrate of perlite + humus soil + coarse river sand (3:4:3) to ensure drainage and maintain a slightly acidic environment. Adding 5% bone meal to soil replacement every spring can enhance water retention. Temperature and humidity control In addition to maintaining the basic temperature of 28℃, special attention should be paid to the temperature difference between day and night not exceeding 8℃. In winter, double-layer insulation sheds can be used to maintain the air humidity at 65%-75%. During the growth period of the water and fertilizer management cycle, the principle of "watering three and resting one" is implemented: watering thoroughly in the morning and evening for three consecutive days, and stopping water is observed on the fourth day. Combine the alternating use of fish protein liquid fertilizer and seaweed fertilizer, and apply additional calcium and magnesium fertilizer every 15 days to prevent fruit cracking. In addition to direct light throughout the day, the light optimization plan for advanced cultivation techniques is recommended to set up a fill light 30cm at the top of the tree canopy to extend the light for 2 hours every day. At noon in summer, a sunshade net is needed to filter 30% strong light to prevent leaf burns. Manual pollination practice 9-11 a.m. Use a brush to dip the male flower pollen and gently touch the female flower stigma. Focus on treating the flowers in the middle and lower parts of the crown, and put them with insect-proof net bags after pollination. The success rate can be increased to 80%. Daily management details modeling and pruning essentials Carry out retraction and pruning in March every year, retaining the 3-4 branches of the main branch. The height is controlled by picking and branch pulling is used to adjust the tree shape to ensure that 8-10 fruiting branches are retained per square meter of crown width. Pest and insect pest control focuses on controlling scale insects and (T-J) diseases. Spray the back of leaves with a mixture of neem oil + diatomite every month. When the diseased branch is found, it is immediately cut off and the wound is smeared with Bordeaux mixture.
By accurately controlling environmental parameters and refined management, even novice gardeners can harvest sweet fruits from trees. It is recommended to regularly test the soil EC value and adjust the maintenance plan according to the phenological period, so that the high-yield period can be entered within two years. The observation data accumulated during the cultivation process will become an important basis for optimizing the planting system.
