Nour
Shading treatment prevents the photosynthesis of the fruit itself, the amount of chlorophyll in the skin decreased rapidly and carotenoid accumulation was slow, and the relative content of sucrose increased significantly. Shading treatment also intensifies the transport of photosynthetic products to the pericarp, thereby reducing the distribution ratio of photosynthetic products in the juice sac and reducing the amount of sucrose in the juice sac. In this way, it affects skin color and pulp sugar accumulation.
Dema
Usually, within a certain range, the amount of sugar increases with increasing temperature, and the amount of acid increases with temperature. Where the storage temperature is high, the sugar content is high, the skin is thin, the acidity is low, the color is pale, and the cellulose in the fruit is also reduced. Especially at night, low temperature reduces breathing intensity and increases sugar accumulation, which can weaken protein synthesis. Promotes the formation of pigments. However, when the accumulated temperature is more than 7000 degrees Celsius, when the fruit is green or even mature, the skin of the fruit is still green.
انی Moisture
Deficiency of water in the soil during the period of fruit expansion obviously affects fruit growth, resulting in small fruit shape and increased acid content. At the late stage of fruit development, proper drying of the soil in citrus orchards can reduce nitrogen uptake and increase sugar, which leads to improved fruit quality.
این Pest crop management and control
Promote nutrient uptake and citrus transport through effective water and fertilizer management. It reduced physiological buds and fruit drop with chemical control and improved the amount of citrus fruits. Promote tree ventilation and light transmission to enhance sugar coloring through plastic quality. Regulate the transport of photosynthetic products through ring cutting and twisting to control fruit growth. By controlling pests and diseases, it reduces the effect of pests and diseases on fruit quality.
