Jixinguo, also known as Jinxiu Haitang, is both ornamental and edible, sweet and sour, and has a unique taste. This kind of fruit tree is robust, with thick leaves and less water evaporation. It can resist the cold and dry climate, and is very suitable for planting in northwest and northeast China, and can adapt to the climatic conditions there. It has high economic value and large development space, and can be widely planted in sightseeing parks and ecological parks. Let's talk about daily maintenance:
Pruning rejuvenation: Pruning rejuvenation is a rejuvenation measure taken after the results due to the influence of years of fruit or malnutrition, as well as the influence of ventilation and light transmission.
Cold maintenance:
Newly planted Cynanchum komarovii has less nutrient reserves, more new shoots, relatively low lignification degree, low resistance to adverse external environment, and is prone to freezing injury in winter. In order to ensure the safe overwintering of seedlings, the following anti-freezing technologies should be adopted:
Spraying 380 times of compound sodium phenolate and potassium dihydrogen phosphate antifreeze four times a week before the yellow leaves in autumn can effectively improve the frost resistance of fruit seedlings and improve their plumpness and robustness. The tree trunk is coated with whitening agent, which is completed after defoliation and before freezing.
You can also build a windbreak wall in the direction of the incoming wind, which can play a cold-proof role. Water the frozen water, and seal it when it freezes during the day and night. Roots are cultivated with soil, and when it freezes in winter day and night, soil is cultivated above the marriage joint to prevent root freezing and marriage joint freezing. Covering for heat preservation, especially when planted in sandy soil, is easy to freeze the roots because of the large temperature difference between day and night in sandy loam, so plastic film mulching or grass mulching can be used to keep the roots warm.
