The application of strong fruit fertilizer from July to September is one of the key technologies for stable production and high yield of citrus, and it is also an effective measure to prevent the phenomenon of the size of citrus.

Grasp the fertilization period July-September coincides with the period of citrus fruit enlargement, the plant needs a large amount of fertilizer, should be timely application of strong fruit fertilizer. In mature fruit trees, strong fruit fertilizers should be applied in mid-July; young fruit trees in early fruiting days should be applied from late July to early August, which is good for strong fruits and early and healthy autumn. Tip; tree-branched citrus trees and hillside citrus groves should be planted early enough, and a well-watered flat ground citrus grove can be applied as late as possible.

Re-emphasizing strong fruit fertilizer During the period of strong fruit, it requires many nutrients and is complete. Therefore, in addition to the appropriate application of available nitrogen fertilizer, it is necessary to use phosphorus, potash fertilizer and organic fertilizer. At this time, the amount of fertilizer should account for about 30% of the total fertilization for the whole year. Precocious and very precocious varieties, such as Miyamoto, Hingjin, and Oita early-growth varieties, should be finished in early July. Late-maturing varieties such as Owari, can be applied in September. Generally, it is better to use compound fertilizers containing nitrogen, phosphorus, and potassium, or fully decomposed pig cow dung and human manure. Fertilizer amount: 1 kg of compound fertilizer per plant, 0.25 kg of urea, or 15 to 20 kg of fully-composed human and animal manure and 0.2 kg of urea per plant. When applying strong fruit fertilizer, potassium fertilizer should also be given priority.

Appropriate application of foliar fertilizer in the strong fruit period from July to August, spraying leaf foliar fertilizers outside the root also has significant effects, and can improve fruit quality. Can spray 0.3% urea, 0.2% potassium dihydrogen phosphate solution, or other multi-element fertilizer solution, spray once every 10 to 15 days, and even spray 2 times better. It is advisable to choose foliar fertilizer before cloudy time or at 10 o'clock in the morning or after 4 o'clock in the afternoon. Because there are more stomatal holes in the leaves, the absorption capacity is stronger than that of foliar surfaces. When the spray is applied, the foliage, leaves, and back are sprayed. Dripping water is appropriate.

Cooling Agent

Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
