How to supplement calcium for apple trees? When is the best time to supplement calcium for apple trees? We also ask experienced netizens to help explainWhen apple trees are deficient in calcium, the tips of the roots turn brown, the branches and leaves grow excessively and become soft in texture, affecting the accumulation of sugars in the fruit, with less fruit bloom and a faint aroma, poor maturation of new shoots, and weakened tree vigor. It also causes a decline in the immunity of the fruit trees, making them susceptible to various bacteria and disease, reducing fruit quality and cutting the next year's yield. Therefore, Zhongdiwang has compiled two methods for calcium supplementation in apple trees, listed below for netizens' reference.
Calcium supplementation method one for apple trees: spraying calcium fertilizer or applying water-soluble calcium fertilizer:
Apple trees have two peak periods of calcium uptake each year: the first peak is about 40 days after petal fall, that is, the young fruit stage, when a high-grade liquid calcium fertilizer can be sprayed 2 to 3 times in succession on the leaves and fruit, combined with applying highly water-soluble calcium when watering for the first time in spring.
The second peak period of calcium uptake is about 40 days before harvest, and on the 2nd to 3rd day after bagged fruit is unbagged, calcium should also be sprayed 1 to 2 more times. In addition, there is pre-harvest calcium supplementation, mainly because as the fruit body continues to expand, the calcium concentration inside the fruit decreases accordingly. Supplementing calcium at this time can not only significantly increase fruit firmness, but also increase the tree's accumulation of calcium.
Calcium supplementation method two for apple trees: applying calcium fertilizer in autumn:
Applying calcium fertilizer in autumn can solve various physiological diseases caused by calcium deficiency in apples. It is best to choose a formulated fertilizer when applying base fertilizer in autumn after fruit drop and before leaf fall. Increase the application of various fully decomposed organic fertilizers as much as possible, because organic fertilizer can improve the soil, build soil fertility, increase soil organic matter content, and provide fruit trees with various nutrient elements evenly and over the long term, especially trace elements, which play an important role in the root growth of apple trees, fruit coloration, and improving stress resistance.
