Breeding method of papaya and crabapple flowers
The swaying papaya crabapple in the spring courtyard can always attract countless envious eyes. This kind of traditional flowers and trees, which combines viewing flowers and fruits, is often mistakenly thought that they need careful care. In fact, as long as they master a few key maintenance skills, novices can easily cultivate a magnificent scene full of flowers and branches. The core point of garden flower maintenance is the golden ratio of sunshine and ventilation. As a typical sun-loving plant, it is necessary to ensure more than 6 hours of direct light every day. An open balcony facing south or southwest is the best choice. In a closed environment, attention should be paid to opening windows regularly for ventilation. Appropriate shade at noon in summer can prolong the flowering period, but it should not be placed in shade for a long time. Although the three-step method for soil improvement does not have high requirements on soil quality, using the ratio of legus soil: garden soil: river sand =5:3:2 can significantly improve the growth rate. Mix bone meal as base fertilizer when turning pots in spring every year, and control the pH value between 6.0 and 6.5 is most conducive to root development. The principle of "seeing dry and wet" in the smart watering system needs to be flexibly applied: keep the soil slightly moist in spring and autumn, observe the state of the basin soil once in the morning and evening in summer, and control the water until the surface layer is 3cm dry before watering. During the rainy season, it is recommended to raise the flowerpot high to prevent stagnant water. Precise fertilization schedule Apply decomposed soybean cake fertilizer during the germination period in March, and apply additional potassium dihydrogen phosphate solution (1:1000) two weeks before flowering. During the fruit expansion period, seaweed fertilizer is applied semi-annually, and organic compost is added before winter to enhance cold resistance. Advanced techniques for reproduction: Stratification treatment during sowing can increase the germination rate by 30%: Mix the seeds with moist vermiculite and refrigerate them for 60 days, and transplant them after the radicle breaks through the seed coat. The three-year-old Vitis chinensis was selected as the rootstock for grafting, and the success rate of using the embedded bud grafting method can reach 85%. In the early stage of ecological control of pests and diseases, garlic extract (100g/500ml) can be sprayed every week, and in severe cases, combined with the biopesticide Bacillus subtilis. For aphid prevention and control, yellow sticky insect board + matrine solution is recommended for dual protection, which is environmentally friendly and efficient.
Through the systematic implementation of these four core maintenance points, we can not only harvest the splendid spring scenery, but also realize the cycle of flowers and fruits year after year. It is recommended to appropriately adjust the watering frequency and fertilization ratio based on the characteristics of the regional climate, and regularly observe the status of the plants, so that this traditional famous flower can glow with new vitality in modern courtyards.
