At present, it is the season when fresh grape varieties begin to be listed on the market. Because of its delicious, juicy, nutrient-rich, and good health care functions, fresh grapes are well-received by consumers. However, the author observed that most of the grapes currently sold in the market lack commercial quality, that is, the appearance is not beautiful. This not only affects the amount of sales, but also affects the price. Because consumers are demanding good fruit taste, they also want to enjoy the beauty from the appearance. Therefore, in order to meet the needs of consumers, the majority of farmers must pay attention to improving the commercial nature of grapes, so as to obtain higher economic benefits. To improve the commercial quality of grapes, it is necessary to strengthen the management of grape ears. The following points are proposed for concrete measures for your reference and application: 1. The number of sparse spikes is directly related to yield, and the level of yield is directly related to the quality of grape berry. In general, quality and output are inversely proportional. If the output is high but the quality is not good, sales are difficult, and the economic efficiency will not go. As long as we take good care of certain natural conditions and ensure the quality of grape berry, we can maximize the production potential of the earth and strive for good economic benefits. The best land strength is not more than 2,500 kilograms or mu; the lower land yield is about 1000 kilograms per mu. For fruit thinning, the ear reserve was determined according to the average ear weight and planned yield of the variety. The sparse spikes were performed in 2 replicates. The first time was about 5 days before flowering. The earing volume was slightly higher than the planned ear opening, and the second time was performed 3 to 5 days after fruit enlargement. This time the last reserved ear number. 2 . Fruit thinning For 1 spike grape, the amount of fruit is inversely proportional to the size of the fruit. With fruit as a dominant species, fruit thinning is particularly important, such as red, rattan and other. The fruit thinning is generally carried out after fruit enlargement. The small fruit, residual fruit, and deformed fruit must be removed. The overlying fulcrum shaft is cut off and the dense fruit is removed from the fulcrum. After the ear grows into a beautiful cone or cylindrical shape. 3 . The spike tip not only improves the fruit setting rate, but also makes the appearance of the ear beautiful. Usually 3 to 5 days before flowering, 1/5 to 1/4 of the ear tip. 4 . On the shoulders of most grape varieties, there is often one to two shoulders. Most of the fruits on the shoulders are ripe at the fruit on the main ear. Therefore, they should be cleared 3 to 5 days before flowering. 5. Increase the fruit weight to increase the single fruit weight, can spray large agent. About 12 days after flowering, the specific operation according to the instructions. 6 . Sugar-enriched color can be sprayed with "grape sugar coloring spirit", but also in the 20 days -25 days after flowering on the mother of the twig or the results of the girdling base girdling, a width of 3 mm is appropriate. To apply nitrogen fertilizer lightly and reapply phosphorus and potassium fertilizers, potassium fertilizer should be applied 30 days before fruit harvest. 7. The ear bagging of the ear bagging can effectively protect the fruit from pests and diseases, avoid drug contamination, and the fruit surface is clean and bright, and the preserved fruit powder has a better overall appearance and improves its commercial properties. Ear bagging is generally performed during fruit enlargement. 15 to 20 days before picking to facilitate coloring. 8 . Aging leaves of turning heads change the direction of the ear during the coloring period of the ear. At the same time, removing the old leaves, sick leaves, and dense leaves around the ear not only facilitates the coloration of the grapes, but also facilitates the maturation of new shoots and the differentiation of winter buds. 9 . Pre-harvest non-irrigation grapes into the fruit after the maturity period of the least water, pay attention to control irrigation. Some growers mistakenly use pre-harvesting irrigation as a measure to increase production, which has a great impact on the quality of the grapes. Although the yield has increased a bit, the sugar content of the grapes has dropped, the acidity ratio has increased due to the change in the ratio of sugars to acids, and the taste has deteriorated, which has led to a decline in the commercial quality and reduced economic benefits. 10. In order to form excellent fruit quality, the grapes harvested in proper period must be able to successfully complete the berry growth and development process and achieve the desired fruit quality, which is the appropriate harvest period of the grapes. Precocious grape varieties need about 110 days to 130 days from sprouting to maturity, mid-maturing varieties need about 130 days to 150 days, and late mature varieties need about 150 days or more. Some fruit growers marketed for the purpose of seizing market share and adopting advance harvesting methods. Because the quality does not meet the requirements of consumers, they often sell at lower prices. As a result, not only have they not increased their income, but they have become counterproductive. As fresh grape sales must be harvested in batches according to the maturity of the grapes to ensure excellent fruit quality, in order to obtain higher economic benefits.
