Citrus is a tropical, subtropical evergreen tree. China is one of the important origins of citrus. Rich in citrus resources, it has been cultivated for more than 4,000 years. Citrus contains abundant B vitamins, vitamin C, flavonoids, polyphenols, carotenoids and other human beneficial components. Its sales account for an important part of China's fruit market. Therefore, ensuring the high yield and stable production of citrus is a topic of concern for all growers. According to the experience of citrus management in recent years, the full-year fertilization techniques for high citrus yield are summarized as follows:
1. Outline of citrus fertilization to promote flower fertilization Fertility, also known as flower before flowering, spring shoots sprouting before flowering, the purpose is to ensure that citrus growth and development of nutrients. Fertilization time is usually implemented from late February to early March (8-10 days) before germination. If the application of the microbial fertilizer Jinbao (click here) or other organic fertilizers, because of its long-term fertilizer efficiency and high utilization rate, the fertilization time can be advanced to 15 days before sprouting. Fertilizers need to include 30% to 40% of nitrogen fertilizer, 30% to 40% of phosphate fertilizer, 20% to 30% of potassium fertilizer and slow-lasting fertilizer. Fertilizer application along the crown can be applied under the crown. This fertilization can promote spring shoots and flowering results.2. Citrus fertilization to protect the fruit fertilizer Fertility Summary Protecting fruit fertilizer, also known as post-flowering fertilizer, after the fall flowering fruit period. It is mainly to improve the fruit setting rate and control the burst of summer shoots. The young fruit of the orange tree is generally formed from May to June, during which the nutrients are consumed. If the supply of fertilizer is insufficient, it can cause fruit drop and fruit drop. Therefore, this fertilization is mainly to protect the fruit, fertilization and more use of foliar spray, can be used 0.3% urea, 0.2% potassium dihydrogen phosphate, hormones (50 ~ 100 mg / kg Naphthyl acetate, etc.). Paul Fruit Fertilizer can be used in combination with Golden Baby Sweetener. The use of Golden Baby Sweetener can overcome all the disadvantages of previous use of hormones and growth regulators. The fruit spraying period can supplement many kinds of trace elements needed for fruit growth to prevent cracking. Increase the soluble solids of fruits by 2%, increase the sugar content of oranges by 0.8-1.5 degrees, color early and have a deep and even color. At the same time can enhance fruit hardness, extend the storage period. The preparation spraying period is about 10-15 days, and 2-3 cycles can be received with good results. Fertilization should be completed from late April to early May. If fertilization is delayed until June, it will cause a large number of new shoots, resulting in a large number of fruit drop. An orchard with a long period of stable fruit can be applied for 1-2 times more fertilizer.
3. Strong fertilization of citrus fertilization Strong fertilizer fertilization is carried out during the fruit enlargement period and is dominated by chemical fertilizers. Its purpose is to improve fruit quality and improve storage performance, and reduce the second physiological fruit drop. The focus of this fertilization is on quick-acting nitrogen fertilizer and phosphate fertilizer, in addition to reapplying additional potassium fertilizer. The proportion of fertilizer is generally: 30% to 40% of nitrogen fertilizer, 20% to 30% of phosphate fertilizer, 40% to 50% of potassium fertilizer. Phosphate fertilizers are preferred for calcium magnesium phosphate or superphosphate, or use organic fertilizers that are decomposed. In areas where there is more rainfall, it can be divided into multiple applications, which can improve the fruit yield and quality, but also enable the growth of autumn shoots to enrich and promote the accumulation of tree nutrients.
4. Application of citrus fertilization fruit fertilizer fertilization General fruit harvesting before and after fruit harvesting, organic fertilizer-based and appropriate mix of available fertilizer according to the circumstances. Early maturing varieties are applied side by side while late mature varieties are applied within one week after harvest to improve fertilizer efficiency and restore tree vigor. It is not advisable to apply the fruit fertilizer too early to avoid fruit turning green. The proportions of fertilizers applied for fruit harvesting were: 20%-30% for nitrogen fertilizer, 40%-50% for phosphate fertilizer, and 20%-30% for potassium fertilizer. According to the situation, the harvested fruit fertilizer can be applied first to quick-acting chemical fertilizers, and then to organic fertilizers (can buy off-the-shelf organic fertilizers or self-made by using golden treasure organic fertilizer starter). Boron or zinc-deficient orchards need to be supplemented with borax, zinc sulfate and other trace element fertilizers.
