Problems solved by technology

[0003] Post-harvest treatment combined with cold storage, that is, passive post-harvest preservation to prolong the shelf life of fruit storage, has been studied a lot; and pre-harvest measures are used to improve the storage quality of fruits, so that the quality of post-harvest stored fruits is better and the shelf life is longer. There is still little research on the method of fruit development, and the method of applying multi-nutrient and multi-functional ingredients to improve the quality of fruit before harvest is even more lacking.

example 1

[0065] Example 1. The test material is the 15-year-old sand pear variety Cuiguan (Pyrus pyrifolia Nakai.cv.Cuiguan). Choose pear trees with tree vigor and uniform growth.

[0066] 30 days after flowering (young fruit stage, cell division stage), spray with 0.1-0.5% plant flower and fruit source nutrient solution (preferably, honey pears, extracts from flower thinning and fruit thinning, containing a variety of pear growth Plant growth hormones necessary for growth, organic and inorganic components), 500mg / L polyamine, 0.2mg / L brassinolide, CO(NH 2 ) 2 (Urea) 0.2-0.5%, superphosphate leaching solution 0.4-0.8%, H 3 BO 3 (boric acid) 0.2%, FeSO 4 (Ferrous sulfate) 0.05~0.1%, ZnSO 4 (Zinc Sulfate) 0.1~0.4%, (NH 4 )6Mo 7 o 24 4H 2 O (ammonium molybdate) 0.02% ~ 0.05%, 18% fruit tree leaf silicon fertilizer 600 ~ 800 times liquid, etc.

[0067] 60d~80d after flowering (fruit expansion stage), spray with 0.1~0.5% medicinal and edible food aloe extract nutrient solution (al...

[0071] Example 2. The test material is the 10-year-old Fujiminori grape sprout "Yongyou No. 1". Choose vines that are large in vigor and uniform in growth.

[0072] 5-7 days after flowering (young fruit stage, cell division stage), spray with 0.1-0.5% plant flower and fruit source nutrient solution, 500mg / L polyamine, 0.2mg / L brassinolide, CO(NH 2 ) 2 (Urea) 0.2-0.5%, superphosphate leaching solution 0.4-0.8%, Na 2 B 4 o 7 10H 2 O (borax) 0.1~0.3%, FeSO 4 (Ferrous sulfate) 0.05~0.1%, ZnSO 4 (Zinc Sulfate) 0.1~0.4%, (NH 4 )6Mo 7 o 24 4H 2 O (ammonium molybdate) 0.02% ~ 0.05%, 18% fruit tree foliage silicon fertilizer 600 ~ 800 times liquid, etc., spray once.

[0073] At 40d~55d after flowering (the second swelling period of berries), spray 0.1~0.5% medicinal and edible plants such as aloe extract nutrient solution (also antibacterial), 10% amino acid nutrient solution 100~700 times liquid, CO (NH 2 ) 2 (Urea) 0.2~0.5%, KH 2 PO 4 (Potassium dihydrogen phosphate) ...

Abstract

A method for improving the quality of southern fruit before picking is characterized in that a quality improving agent A, a quality improving agent B and a quality improving agent C are sprayed on the southern fruit during a fruit cell division period, an expanding period and a ripe period respectively; and the southern fruit relates to honey pears, waxberries or grapes. Compared with the prior art, the method has the advantages as follows: before picking, people combine quality improvement with initiative fresh keeping and focus on improving the quality of the southern fruit before storage, so that the nutrition and the storage level of the picked fruit are substantially improved while compared with those of conventionally produced fruit, and the proportion of high-quality storable big fruit is increased.

Description

technical field [0001] The invention relates to a method for improving fruit quality, which belongs to the technical field of agriculture. Background technique [0002] Red bayberry, grape and honey pear are dominant fruits in the southern region. The areas of waxberry, grape and honey pear in Zhejiang Province are 1.27 million mu, 383,000 mu and 356,000 mu respectively, the output is 405,000 tons, 670,000 tons and 391,000 tons respectively, and the output value is 4.85 billion yuan, 2.61 billion yuan and 1.65 billion yuan respectively. billion, occupying an important position in the province's agricultural economy. The supply season of these three dominant fruits is from June to August, which is the off-season of fruits in the north and south, and they have strong market competitiveness. However, due to the fact that the production season is a high-temperature season, the fruit is perishable and cannot be stored. For example, red bayberry "changes in color in one day, tas...
