Apples are a cash crop and are grown in all parts of our country. Among them, Shandong, Hebei, Shaanxi and other places have high yields of apples. However, during apple growth, fruit dropping occurs frequently, affecting apple yield and quality. So what is the reason for apple fruit dropping?
Climate change is the main reason for apple fruit drop. During apple growth, natural factors such as temperature and moisture have a huge impact on fruit growth, of which temperature is one of the most important factors. When the temperature drops sharply or cold damage occurs, apples will be caused to fall off, reducing their yield and quality.
Apple fruit drop is related to improper use of fertilizer. If the fruit tree lacks nutrients or too much fertilization, it will lead to an imbalance in the soil pH, which will hinder plant growth and lead to apple fruit drop.
Pests and diseases are an important reason for apple fruit drop. Apples are vulnerable to pests and diseases during their growth, such as the European Cerobug and apple thrips. They will egg on apples, causing apple fruit drop and quality decline.
Freezing damage during flowering causes fruit loss. During spring flowering, if large-scale cold damage weather occurs, pollen will fail to grow, making apples unable to develop normally and eventually causing them to fall off.
Malnutrition can affect the quality of apple fruits. When over-dense planting or drought and lack of water, soil nutrients will be completely lost, resulting in slow apple growth and decline in quality, and also affecting its yield.
Mastering the appropriate pruning time can reduce fruit drop. The pruning of the canopy helps apple grow and adjust the tree shape, and allows air circulation and sufficient sunshine. The appropriate pruning time is carried out before the crown stops growing and dormancy, avoiding fruit drop after tree crown pruning.
Improper irrigation methods are also one of the reasons for apple fruit drop. Improper irrigation methods can cause apple growth to be blocked and promote fruit shedding. Appropriate watering methods can promote the normal growth of apples and effectively prevent apple fruit drop.
Controlling pests and diseases can effectively reduce the rate of fruit drop. Pests and diseases are very harmful to apple growth. Therefore, timely prevention and control measures can avoid the spread and spread of pests and diseases, which is conducive to the growth and development of apples.
Proper shading helps reduce fruit drop. Long-term exposure to the sun can cause the fruits on apple trees to lose water and affect their growth and development. Scientific and reasonable setting of sunshade nets will help reduce apple fruit drop.
Close planting and topdressing will also affect the growth of apples. Reasonable close planting spacing and appropriate topdressing can promote the normal growth and development of apples and avoid harm to apples caused by excessive close planting and excessive topdressing.
Picking buds at the right time is very important to reduce apple fruit drop. Removing unnecessary buds and short branches on apple trees at the right time can promote the normal growth and development of apples and effectively reduce fruit drop.
Reasonable pruning and short pruning are conducive to the growth of apple trees. Through reasonable pruning and short pruning, the crown structure can be adjusted, so that the apple tree can get better air and light, thereby effectively reducing apple fruit drop.
Timely pruning of branches can reduce the rate of apple fruit dropping. During apple growth, timely pruning of branches can reduce the shift of the center of gravity and avoid fruit falling caused by natural factors such as wind blowing.
Regular fertilization can promote the growth of apple trees. Fertilizing apples at appropriate times can increase their nutrient content, benefit the development of trunks, leaves and fruits, and effectively reduce the rate of apple fruit drop.
Many factors affect the rate of apple fruit drop. Apple fruit drop is affected by many factors, including climate change, pests and diseases, improper use of fertilizers, etc. It is necessary to pay attention to these factors in production and take reasonable measures to effectively reduce the rate of apple fruit drop and improve apple quality and yield.
