How to improve the quality of Red Fuji Apple

How to improve the quality of Red Fuji apples? Please also have red Fuji apple planting experience to help introduce netizens High quality red Fuji apple requires fruit shape, obvious high stake, smooth fruit surface, bright color, moderate fruit size, moderate crispness, good fruit flavor, high soluble solids content, and low pesticide residues. Therefore, the planting network sorted out the methods to improve the quality of Red Fuji apples, listed in detail below for netizens 'reference. Step 1: Rational fertilization: In late April, the tree tray is planed, about 15 cm deep near the trunk and about 25 cm at the outer edge, so as to avoid cutting off too many roots, minimize damage to shallow roots, and combine deep turning between rows to achieve the purpose of comprehensive loosening. In autumn, base fertilizer should be applied, 1-1.5 kg of high-quality manure, compost or livestock manure should be applied for each kilogram of fruit, and topdressing should be timely. The ratio of nitrogen, phosphorus and potassium should be 10:7:8. Generally, 1000 kg of fruit should be produced. Pure nitrogen fertilizer is 8 kg, effective phosphorus fertilizer is 5.5 kg, and effective potassium fertilizer is 6.4 kg. Nitrogen fertilizer should be applied in early stage, especially in spring and within one month after flowering, which is beneficial to fruit coloring and improving fruit shape index. In early August, after the fruit begins to color, nitrogen fertilizer should be controlled and phosphorus and potassium fertilizer should be increased. Step 2: Scientific watering: Fuji apple focus on watering water before flowering, after flowering water and frozen water. Pre-flowering water is generally combined with topdressing from mid-late March to early April. This period should not be too much irrigation, so as not to reduce ground temperature, affecting root development. It is very important to irrigate after flowering at 10 days after flowering to reduce fruit drop, promote fruit development and flower bud differentiation. Freezing water is poured in early November before the soil freezes. In addition, if the soil is dry in the early rainy season, it still needs to be watered 1-2 times. Step 3: Prune the fruit trees: According to the previous planting experience of Red Fuji apple, most large fruits were planted on the lower secondary fruiting branch group, especially on the short fruit branch transformed from strong and vigorous branches, so the lower secondary fruiting branch group should be cultivated during pruning. When pruning, we should maintain an appropriate branch-fruit ratio, generally 5-10:1. The branch-fruit ratio is too large or too small, and the fruit is not long. In order to solve the problem of individual and group lighting, attention should be paid to pruning during the whole growth period, such as bud wiping and bud removal in April and May, twisting and branch taking in June, thinning in September, etc. Step 4: Sufficient light: The length and intensity of illumination of fruit are related to its quality. Therefore, the position of illumination, lateral illumination and internal illumination of tree body should be adjusted as much as possible during pruning to increase the coloring degree and soluble solid content of fruit. Generally, the population coverage rate of the orchard is not more than 80%, the number of branches per mu after winter pruning is about 100,000, and the transparency of the tree body is not less than 40%.
