Nutritive liquid for improving seedless grape fruit quality

Abstract

The nutritive liquid for improving seedless grape fruit quality consists of over ten kinds of organic and inorganic nutritive liquid and is sprayed to anthotaxis of seedless grape 7-10 days before anthesis and to young grape fruits 10 days, 20 days and 30 days after pollination. Compared with seedless grape without the nutritive liquid sprayed, the seedless grape with the nutritive liquid sprayed has fruit stem tension resistance raised from 86.5 g to 452.1 g, fruit compression resistance raised from 672.5 g to 2144.4 g, sloughing rate lowered from 44.8 % to 20.1 %, fruit weight increased from 1.55 g to 3.63 g, fruit stem tension resistance after storage in cool house for 10 days raised from 61.0 g to 415.0 g, fruit compression resistance after storage in cool house for 10 days raised from 605.0 g to 2135.0 g, and sloughing rate after storage in cool house for 10 days lowered from 81.6 % to 45.6 %.

Description

technical field [0001] The invention relates to an agricultural chemical fertilizer, in particular to a nutrient solution for improving the quality of seedless grape berries. Background technique [0002] Grape has gradually become one of the main fruits that people like to eat because of its rich nutritional content. As a worldwide fruit, its cultivation area and output have ranked second among all kinds of fruits and are showing an increasing trend year by year. Seedless grapes are easy to eat, unique in flavor and high in quality, so no matter fresh eating, drying or processing, they have become an important direction of world consumption. In the United States, 80% of fresh table grapes are seedless grapes. Australia, South Africa and Europe The research and development of seedless grapes are also very important in grape producing countries such as China. my country is also a big grape-producing country, with a cultivation area of ​​40,000 hectare...

AI Technical Summary

Problems solved by technology

At present, gibberellin (GA) is generally only used in the production of seedless grapes in my country. 3 ) to increase the weight of berries, but the effect is often not good due to the use period and improper use concentration

In recent years, the Turpan area of ​​Xinjiang began to use the "Pyrazole Grape Swelling Agent" produced by the Lanyue Technology Development Company of the Sichuan Academy of Agricultural Sciences to increase the size of the seedless white grapes. Generally, the size of the fruit can be increased by 1-1.5 times. However, a series of problems such as reduced sugar content, delayed ripening, and serious deformation of fruit stems and cobs appeared during use.
