Breeding method of Hovenia trifoliata
Hovenia trifoliata is a characteristic tree species with both ornamental and medicinal values. Its unique crutch shape and strong adaptability have attracted the attention of horticulture enthusiasts. Mastering scientific Hovenia trifoliata cultivation methods can not only improve the survival rate, but also promote the high-quality and high-yield fruits. This article will systematically analyze the key points of full-cycle management from seedling raising to adult plants to help you create healthy and lush Hovenia trifoliata plants. Key elements of environmental regulation, temperature and light management, Hovenia trifoliata has excellent cold resistance and can grow between-15 ℃ and 25℃. It needs to avoid direct strong light during the seedling period, and mature plants need a full sun environment. It is recommended to build a sunshade net when the high temperature exceeds 35 ° C in summer, and anti-freezing measures such as white tree trunks are needed below-30 ° C in winter. Collaborative management of water and fertilizer adopts the irrigation strategy of "two controls and three promotion": maintain soil moisture at 60%-70% in spring and autumn, increase the flowering and fruit period to 75%, and drop to 40% in winter. Fertilization follows the principle of "ratio of nitrogen, phosphorus and potassium in stages." Nitrogen fertilizer accounts for 60% in seedling stage, high phosphorus and potassium compound fertilizer is adjusted during fruiting stage, and 5-8kg of organic fertilizer per plant is applied every season. Efficient sowing techniques for reproduction and shape management are preferred for mother tree seeds more than 20 years old. Maintain 40% humidity during sand storage, and soak them in warm water to break the cuticle before sowing. The double-row ridge sowing method was used, with a row spacing of 50cm×30cm, and then covered with straw to moisturize, and the emergence rate reached more than 85%. Key points of modeling and pruning: breeding method of Hovenia trifoliata
The "three-level pruning method" is implemented after falling leaves: the first level is to cut off pest and insect branches, the second level is to cut off dense branches, and the third level is to shape and prune. Keep the height of the trunk at 2.5-3 meters, cultivate 3-4 main branches to form a open-heart crown, and maintain the light transmittance of 60%. The comprehensive disease prevention and control system for pest and disease prevention and control has established a three-level protection of "prevention-monitoring-management": 70% thiophanate methyl 800 times solution is sprayed for ulcer diseases, and 1:1:200 Bordeaux mixture is applied for leaf blight, in conjunction with the elimination of sick and disabled bodies to reduce the pathogen base. During the ecological pest control and aphid outbreak period, 40% dimethoate EC 1500 times solution was combined with biological control of ladybugs. Yellow sticky plates were set up to monitor insect population density to maintain the vegetation diversity in the park and form a natural barrier.
Through systematic implementation of environmental regulation, refined management and pest control, the efficiency of Hovenia trifoliata planting can be significantly improved. It is recommended to make a maintenance calendar based on the phenological period, regularly test the soil EC value, and use modern gardening equipment to achieve precise management, so that this "Oriental Grape Vine" can bloom with its unique charm.
