Fruit trees are generally perennial, long-term growth in a fixed location, and periodically absorb some of the nutrients in the soil. If you neglect the nutrients needed to supplement fruit trees, it will easily lead to the occurrence of pests and diseases, the lack of certain nutrients, causing physiological Damage caused by reduced production and quality, especially the large-scale application of nitrogen, phosphorus, potassium fertilizer, while ignoring the supplement of trace elements and fertilizers. Trace elements play an important role in the growth and development of fruit trees. Zhengbao Si-Ca fertilizer is rich in trace elements: silicon, calcium, magnesium, sulfur, boron, manganese, iron, zinc, etc. After fruit trees are used, the fruit is ripe, the color is fresh, and the hardness and sugar content of the fruit are increased. Yun, to promote the development of Apple to the level of high quality fruit. Grass Seed,Cynodon Dactylon,Elymus Dahuricus,Onobrychis Viciifolia Chengdu Lv Mu Tian Xia Agricultural Technology Co.

Application effect of silicon-calcium fertilizer on apple trees (1) Strengthen tree vigor and increase yield. Apple is a perennial fruit tree. Apple trees grown from 8 to 9 years produce about 150 kg of apples each year. The apple tree is fixed in a small area for a long time. Absorbing a large amount of nutrients in the soil will inevitably cause the deficiency of these nutrients. Especially, silicon and calcium fertilizer have never been artificially supplemented, which affects the apple tree. With normal growth and further high yields, one month after the application of silicon-calcium fertilizer to apple trees, the effect of promoting the growth of apple trees is clearly demonstrated. The absorption rate of silicon-calcium fertilizer in apple trees is relatively fast. The apple tree branches treated with silicon-calcium fertilizer are thick, and the whole tree vigor grows evenly and healthily. The leaves are enlarged and flat, straight and thick, and the color is dark green, indicating the surface of the leaves. More silicified cells have formed and the chlorophyll content has increased significantly. At the same time, the number of leaves of fruit trees is moderate, and the ventilation and light transmission are good. Apples have an increase in yield of more than 10%, while other apple trees with almost the same conditions do not grow branches with silicon and calcium fertilizers and have small leaves. Leaf margin curling is uneven, leaf color is shallow, leaves are few, leaves are not straight, cover each other, poor photosynthetic ability, the overall performance of the general tree vigor. The above differences are mainly due to the fact that fruit trees absorb a large amount of silicon dioxide. Silica forms silicified cells in the surface tissues of stems and leaves to silice the epidermis, which makes the leaves thicker and becomes more resilient, straight and flat. , conducive to the full photosynthesis. In addition, the application of silicon-calcium fertilizer can activate phosphorus in the soil, so that the phosphorus fixed in the soil can be absorbed, thus indirectly providing Apple with a large amount of phosphorus to promote protein synthesis and improve fruit quality. Therefore, the application of calcium-silicon fertilizer can also save the amount of phosphate fertilizer. Silicon-calcium fertilizer also contains a large amount of zinc, iron, manganese and other trace elements. These elements are also added to the apple tree at the same time to balance its nutrient supply, thereby greatly promoting the growth and development of fruit trees.
(2) To improve quality and early maturity, the current poor quality of apples and low quality fruit rate make it difficult to enter high-end markets at home and abroad, which has become the main contradiction that restricts the healthy development of apple production. In response to this problem, in the apple formula fertilization, silicon-calcium fertilizer should be applied. The coloration of apples treated with silicon-calcium fertilizer is 3 to 5 days earlier than that without silicon-silicon fertilizer. The fruit matures about 10 days earlier, and the color is brighter and the fruit is larger. The supply market can be improved by one grade. This is mainly due to the balanced nutrition and robust trees after the application of silicon and calcium fertilizers. Increased leaf area allows for full photosynthesis and provides sufficient carbohydrates for apple growth. At the same time, due to the increase in fruit and fruit ratio of silicon-calcium fertilizer, mineral nutrient supply is abundant, and the supply of phosphorus is greatly increased, resulting in increased sugar content of the fruit and improved apple aroma and taste.
(C) increase the hardness, improve resistance to storage and transportation, silicon is a quality element, has the effect of improving the quality of agricultural products, and is conducive to apple storage and transportation. Applying 5 kg of silicon-calcium fertilizer per apple tree can increase the hardness of the fruit to a more ideal degree, and it has better resistance to storage and transportation. 8 to 15 years of apple trees, each plant applies about 5 kilograms of silicon and calcium fertilizer. It is advisable to mix apples with soil and mixed fertilizers in autumn and winter and early spring.
