Causes of uneven size of citrus fruits
In the autumn shoot growth period of citrus, it is also the final expansion period of fruit, but at this time, the phenomenon of uneven fruit size appears, which can not be improved at this time. If the fertilizer and water management is strengthened, the large fruit will appear floating skin. So what is the cause of citrus fruit size? Let's get to know each other.
1. Direct cause
In the first physiological fruit dropping period of citrus, there is no fruit drop, or very few fruit drop, until the second physiological fruit drop, the big fruit and small fruit drop together, so the remaining young fruit has big and small, resulting in serious fruit size in the later period. If the first physiological fruit drop is normal, then the bad small fruit drops, and the remaining normal young fruit will be relatively uniform. The main reason for the first physiological fruit drop is that there are flowers but no spring shoots, and the tree nutrients concentrate on the fruit, which affects the normal fruit drop of the first physiological fruit drop.
2. Indirect causes
In the control of winter because of improper use of chemicals, too high concentration or too many times, will cause spring flowers without shoots. In addition, the phenomenon of flowers without shoots is also common for plants with weak tree vigor, and it is easy to have normal spring shoots without flowers when the tree vigor is too prosperous, and there are many reasons for weak tree vigor, such as insufficient nutrients and damaged roots.
3. Preventive measures
In the fruit expansion period nutrient deficiency, the most easy to lack fertilizer in May-July, then generally do not fertilize or less fertilizer, afraid of a large number of small spoons, and tree nutrient deficiency, easy to form large and small fruit serious. Can be used in just flowering is a drop of Xie Hua, potassium fertilizer and high-quality water-soluble fertilizer mix. When spraying winter shoot control chemicals, choose paclobutrazol + potassium dihydrogen phosphate single spray, mainly spray autumn shoot position 1-2 times, so it is safer, not suitable for whole plant spray, weak trees, large fruit hanging quantity, late fruit trees spray once or not spray.
