Problems solved by technology

[0003] However, during the fresh-keeping period of longan fruit hanging on the tree, with the prolongation of time, the pericarp H 2 o 2 Accumulation, the content of MDA increases, the accumulation of active oxygen will start membrane lipid peroxidation, promote fruit aging, and then cause the content of soluble solids in the fruit to decrease, the rate of fruit drop to increase, the hilum to protrude, the fruit to thaw, and the peel to brown , making the internal quality and appearance quality of the fruit deteriorate

Embodiment 1

[0014] Mix 1 part by weight of vitamin C and 1 part by weight of calcium nitrate as a medicament, dilute it 1000 times with water, use a knapsack sprayer to spray the "Lidongben" fruit ears of Zhangwan Orchard in Ningde, Fujian Province, and spray 15 days before the longan matures. Once, spray again 5 days before maturity, with dripping water as the degree, and the rest of the production management is carried out according to the daily management of normal longan orchards; at the same time, it is compared with only spraying water and spraying 1000 times of acetylsalicylic acid to investigate the effect of different treatments on the longan orchard. See Table 1 for the results of the effects of longan fruit quality during hanging on trees.

[0017] It can be seen from Table 1 that with the prolongation of the preservation period of "Lidongben" fruit,...

Embodiment 2

[0021] Mix 1 part by weight of vitamin C and 1 part by weight of calcium nitrate evenly as a medicament, dilute it with water 1000 times, and use a mechanical sprayer to spray the "Fuyan" fruit ears of the Longan Production Park in Wumashan, Fuqing, Fujian Province, before the longan matures. Spray once every 15 days, and then spray again 5 days before maturity, with dripping water as the degree; the rest of the production management is carried out according to the daily management of normal longan orchards; The effects of different treatments on the fruit quality of longan fruit hanging on the tree during the fresh-keeping period are shown in Table 2.

Abstract

The invention discloses a medicament capable of guaranteeing the quality of longan in a period of keeping fresh on a tree and an application method thereof. The medicament is prepared by mixing vitamin C and calcium nitrate according to a weight ratio of 1: 1. In use, the medicament is diluted by 1000 times with water, and the diluted medicament is sprayed on longan clusters 15 days and 5 days before mature of longan respectively, wherein the spraying amount of the diluted medicament is as much as the diluted medicament drips downward; and other normal daily management of an orchard of longan is carried out. The medicament is scientific and reasonable in formula; the application method is simple and has low cost; and the medicament and the application method can prevent deterioration of the quality of longan in the period of keeping fresh on the tree, maintain inherent and appearance quality of longan, are beneficial for delaying the period of keeping fresh on the tree, have substantial economic benefits and suitable for large-scale promotion and application.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a medicament for ensuring the quality of longan hanging tree fruit during the fresh-keeping period and an application method thereof. Background technique [0002] Longan is one of the main subtropical fruit trees in southern my country. Its fruit is rich in nutrition and has high nutritional value, and has always been loved by consumers. Thailand's off-season longan is often treated with sulfur to prolong the freshness of the fruit when it is exported, which leads to serious pollution of the fruit and is not beneficial to human health. Ningde and Fuqing in Fujian are the northernmost regions for longan cultivation in my country, and they have geographical advantages for the development of late-maturing longan. On the basis of late-maturing varieties, the implementation of tree-hanging fresh-keeping technology can further delay the harvest period of longan and ...
