Novel citrus fruit cracking preventing method

Abstract

The invention discloses a novel citrus fruit cracking preventing method. According to the method, after fruit setting, citrus tree branches, leaves and fruits are sprayed with special fertilizer once every 10-15 days till citrus coloring. The special fertilizer is prepared from 40-80 mL of FIP, 20-50 mL of urea-based chelated ionized calcium, 30-60 g of health potassium, 10-25 mL of shunzhi and 25000-35000 mL of water. Compared with the prior art, the method has the advantages that citrus tree branches, leaves and fruits are sprayed with the special fertilizer obtained according to a specific ratio from fruit setting to citrus coloring, so that citrus peel can sufficiently absorb nutrients (such as calcium) in the special fertilizer, the mechanical strength of peel is improved so that pressure generated by fruit growth and water absorption can be resisted sufficiently, and then citrus fruit cracking rate is effectively reduced and can be controlled to be lower 1%.

Description

technical field

[0001] The invention relates to a new method for preventing citrus fruit from cracking, and belongs to the technical field of citrus planting. Background technique

[0002] Fruit cracking not only affects the appearance quality of citrus, but also affects the storage and processing of citrus. The cause of fruit cracking is mainly that the citrus pulp grows faster than the peel. Under the high temperature and scorching sun in summer and autumn, fruit cracking is more likely to occur after a long drought and heavy rain. The more the juice cells of the fruit petals, the thinner the peel, the greater the probability of fruit cracking. Also known as cotton orange, cotton orange) and so on. Among all citrus varieties, Mianju is a variety with excellent appearance and internal quality. It is a characteristic geographical variety in Xing'an County, Guangxi. However, the fatal defect of this variety is that it is particularly prone to fruit cracking. Generally, the...
