Problems solved by technology

[0003] At present, the off-season longan cultivation and longan fresh-keeping technology have not really succeeded in China. Although the off-season longan cultivation in Thailand is successful, the exported fruits are treated with sulfur, which is seriously polluted and is not conducive to human health. It is boycotted by many countries.
Fresh-keeping technologies other than sulfur have not been successfully researched at home and abroad, and the research is relatively difficult

Embodiment 1

[0019] Use a knapsack sprayer or a mechanical sprayer to spray the fruit ears of the Fuyan variety in Ningde, Fujian Province. Spray once 20 days before the longan matures, and spray again 10 days before the maturity. The daily management of normal longan orchards is carried out.

[0020] The medicament used is: 1 part of Baitai fungicide and 2 parts of potassium dihydrogen phosphate are uniformly mixed according to the parts by mass; when the medicament is used, it is mixed with 2000 times of water.

[0021] After the measures were taken for the Fuyan variety, no phytotoxicity occurred on the ear, and the harvest of the fruit was delayed from September 10 to September 20, and the harvest was delayed for 10 days. The color of the fruit did not deepen, the shape and quality of the fruit remained normal, and the fruit drop rate was low. at 6%.

Embodiment 2

[0023] Spray the ears of Dongbao No. 9 variety in Fuzhou, Fujian Province with a knapsack sprayer or a mechanical sprayer, and spray it once 20 days before the longan matures, and spray it again 10 days before the maturity; production Management is carried out according to the daily management of normal longan orchards.

[0024] The medicament used is: 1 part of Baitai fungicide and 2 parts of potassium dihydrogen phosphate are uniformly mixed according to the parts by mass; when the medicament is used, it is mixed with 2000 times of water.

[0025] After the measures were taken for Dongbao No. 9 variety, no phytotoxicity occurred on the ear, and the harvest of the fruit was delayed from October 5 to October 20, and the harvest was delayed for 15 days. The color of the fruit did not deepen, the quality of the fruit shape remained normal, and the fruit dropped. The rate is less than 3%.

Embodiment 3

[0027] Use a knapsack sprayer or a mechanical sprayer to spray the ears of the Lidong variety in the Ningde area of ​​Fujian Province, with the degree of spraying wet to dripping water, spray once 20 days before the longan matures, and spray again 10 days before the maturity; production management according to The daily management of normal longan orchards is carried out.

[0028] The medicament used is as follows: 1 part of Baitai fungicide and 2 parts of potassium dihydrogen phosphate are uniformly mixed according to the parts by mass; the medicament is mixed with 2500 times of water when used.

[0029] After this measure was taken on the Lidong variety, no phytotoxicity occurred on the ears, and the harvesting of the fruit was delayed from October 19 to November 10, with a delay of 20 days. The color of the fruit remained green, the shape and quality of the fruit remained normal, and the fruit drop rate less than 2%.

[0030] The following is an experiment on the effect of...

Abstract

The invention discloses a method for delaying the harvesting of longan fruit. The medicament used is: according to the mass parts, 1 part of Baitai bactericide and 2 parts of potassium dihydrogen phosphate are evenly mixed; when the medicament is used, it is mixed with 2000-2500 double use; when in use, use a knapsack sprayer or a mechanical sprayer to spray the longan fruit ears to the extent of spraying wet to dripping water, and spray twice 20 days and 10 days before the longan matures; production management is carried out according to the daily management of normal longan orchards That's it. The medicament formula of the invention is scientific and reasonable, the implementation method is simple, the implementation cost is low, the longan fruit can be prevented from delayed harvest quality deterioration and a large number of fruit drop, effectively maintain the fruit quality, ensure the yield, have significant economic benefits, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for delaying the harvest of longan fruit. Background technique [0002] Longan is a famous subtropical fruit native to my country. Its fruit is rich in nutrition and has been regarded as a tonic since ancient times. It is known as "Southern Ginseng". my country's longan production and area both rank first in the world, and its maturity period is later than that of Thailand, Vietnam and other major producing countries. It has the advantage of late maturity and broad development prospects. Fujian is located in the northern edge of the subtropical zone, and its longan production ranks among the top in the country. In 2010, the planting area of ​​longan in Fujian Province was 1.06 million mu, ranking first in fruit cultivation area; the total output was 230,000 tons, ranking fourth in fruit output. Production and sales involve more than 200,000 rural employ...
