The phenomenon of young citrus fruit dropping is more serious in rainy weather. How to deal with it?
Citrus is a fruit, and there are more and more fruits. How do fruit farmers manage them? The year is in spring, citrus flowers bloom in spring, carrying the year's output and orange friends as evergreen fruit trees, citrus exotic and long-lived growth, not only for nutritional needs, but also very sensitive, tolerant, and March, large Most citrus-producing areas have more rain and climatic conditions.
The growth and development of trees and flowers causes stress, causing a lot of trouble throughout the flowering period. The impact of low-temperature rain on citrus 1 rain and multiple trees. Every time the temperature is less than 12°C for 3 consecutive days or more, it is usually called a cloudy day. If it is also accompanied by precipitation, it is a low-temperature day. rain. Typically, citrus trees are at least 12.8°C to resume growth. When it is lower than this temperature, physiological activity will be inhibited or even stagnant, resulting in new sprouts and bean sprouts being weaker and susceptible to the effects of cold. Reverse roll and freeze. Rainwater will increase soil moisture and further reduce soil temperature. The root system will be starved of oxygen and hydrophobic absorption will be reduced. It does not meet the huge nutrient consumption of the current tree. The leaves fall off after using the previous year's reserve nutrients. 2. In the form of citrus flower buds, the development of flower organs requires not only a variety of mineral nutrients, but also sufficient organic matter. Long-term low-temperature rainfall leads to insufficient gamma, poor photosynthesis, and development of citrus flowers and young fruits. It also affects insect activity and is not conducive to pollution, resulting in a large number of flower drops. 3. More rain means more pests. Citrus diseases are frequent in spring, such as sores, brown spot disease, anthracnose, and gray mold. The extent of rain occurs, sedimentation and serious diseases.
On the one hand, rain can provide conditions for the spread of diseases; on the other hand, if there is more rain, the trend is affected, disease resistance is reduced, and the feeling speed is increased. In addition to diseases, long rains cause serious damage from a common pest of citrus - flower brats with large feathers. How to manage citrus prices? Stable tree trend, active flowers continuous rainy days, root system absorption is weak, photosynthesis can be laminated, leaves should be chased in the rain, choose functional foliar fertilizers containing amino acids, humic acid, boron sources, cell grading. etc. For yellow leaves that are heavier on longevity, Sea Spirit's Restorative Biostimulant, supplemented with Tree Nodules, stimulates root growth and size. Drainage and shake flowers, dirty pest-resistant gardens are low and there is water phenomenon, it is necessary to dye in time to reduce the humidity of the orchard; flowers are flowing, resistant to flowers, and reduce the occurrence of gray mold. For sore diseases, brown spot disease, anthracnose, etc., you can choose to win (75% trichosporin dry)) Citrus is now the bud, and seal the perforation, when the bud is white, the femora is reduced. When there is a lot of rainfall during the flowering period, you must pay attention to the supplementation of various diseases, otherwise it will be too late.
