What harm does not produce acidification of soil acidification small head is why Apple will produce the following three cases how do serious apple orchard soil acidification, nutrient uptake and one of the most serious is the calcium soil occur. Fruit calcium deficiency occurs once bitter pit disease prevention apples rot, while calcium and a table of light elements, calcium apple table light is poor, a fruit is low. Second, acidic soils prone to manganese poisoning, impede nutrient transport, the main branch of a "snake swallowing a mouse" shape, presenting IBN, Shaotou appear small dead branches, weak grower serious. Third, soil acidification, soil compaction easy, poor ventilation, stunted roots, and soil-borne diseases increase, root diseases easily spread. Promotion of acid soil improvers years - "Baume" is the best in acid soil improver, which has been used to recognize and growers become an indisputable fact. 2014 apple blossom and flower bud abortion less fertile relationship with climate phenomena 1. big rain, heavy loss of fertilizer. 2. serious waterlogging, root damage to apples, fertilizer absorptive capacity. 3. rain, increased the use of low soil acidification, fertilizer. 4. rainy days more, insufficient light, flower bud physiological differentiation poor foundation. 5. Root damage fertilizer absorption capacity is weak, inadequate nutrition. 6. DIF small, large respiration, tree nutrition consumption, less accumulation, poor quality of morphological differentiation of flower buds.
