Applying organic fertilizer in citrus production can not only meet the nitrogen, phosphorus and potassium needed for growth, but also supplement trace elements such as magnesium and zinc, and improve soil acidity and soil bulk density, and improve fertilizer utilization. Improve the symptoms of citrus deficiency and increase soil fertility, thereby increasing its sweetness.
2, reasonable spraying of foliar fertilizer
In the early, middle and late stages after fruit-hanging, the application of organic foliar fertilizer can be used. It can be used with humic acid foliar fertilizer, alginic acid foliar fertilizer, such as sea elf bio-stimulant, etc., which can improve leaf photosynthesis and enhance stress resistance. Sex, promote coloration, improve quality, and mature early.
3. Scientific water control
Under the premise that the water supply basically meets the needs, the moderate water deficit in a certain period of time has no adverse effect on the fruit quality. Properly maintaining the soil of the citrus orchard in the late stage of fruit expansion can reduce the absorption of nitrogen, and can also increase the soluble solids and sugar content in the fruit juice, which is conducive to the improvement of fruit quality.
4, timely harvest
Different varieties and different regions have different maturity stages. It is necessary to decide whether to harvest according to the maturity of the fruit. It is not suitable for too early or too late.
Premature harvesting, the nutrients in the fruit can not be completely transformed, affecting the quality and yield of the fruit.
Late harvesting, although the sugar content increased slightly, the fruit drop and floating fruit will also increase, resulting in a decline in the annual output.
The factors such as output, quality, and tree potential should be considered comprehensively and harvested at the right time!

Cosmetics are compound mixtures made from various raw materials after reasonable blending and processing. There are many types of cosmetics raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: base raw materials and auxiliary raw materials. The former is a main raw material of cosmetics, which occupies a large proportion in cosmetic formulations, and is the main functional substance in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other characteristics to cosmetics. These substances are not used in large amounts in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production processes such as heating, stirring and emulsification.
