Field culture european large cherry budbreaking chemicals and budbreaking method in regions south of the Changjiang river

Abstract

The invention relates to a dormancy-breaking agent of an European large cherry cultivated out-door in the region at the south of the Changjiang River, and a dormancy-breaking method thereof, which are used for carrying out dormancy-breaking to the European large cherry and promoting the growth of an ovule and a megaspore. The dormancy-breaking agent is prepared by diluting a cyanamide solution of 50 percent to 1-2 percent and then being added with osmotic agent fatty alcohol polyethenoxy ether of 0.05 percent. The European large cherry is treated for two times. The first treatment is carried out about 30 days before the sprouting of the European large cherry and the whole branch of the European large cherry is sprayed up by using the dormancy-breaking agent; the second treatment is carried out after one week of the first treatment, and the same dormancy-breaking method is treated repeatly for consolidating the effects. The method is applicable to the large cherry varieties of 'early-red precious stone', 'red light', 'early-mahapphala', 'pioneer', 'Lapins' and the like. The dormancy-breaking agent has easy preparation and safe use, and can lead the European large cherry to sprout in advance for more than one week, with neat sprout and blossom, the flower quantity is increased, the percentage of fertile fruit is improved, the growth of the young sprout is promoted, the leaf area is increased and the fruit quality is enhanced.

Description

technical field [0001] The invention relates to a sleep-breaker and a sleep-breaking method for open-field cultivation of European cherry in the south of the Yangtze River, which solves the problem that the flowers of the open-field cultivation of European cherry in the south of the Yangtze River are false, and belongs to the technical field of agricultural and forestry crop cultivation. Background technique [0002] European cherry is one of the important fruit tree species in my country. Because of its good economic benefits, high nutritional value and broad market prospects, it has become a new growth point for the development of my country's fruit tree industry. Since the early 1980s, some agricultural scientific research institutes and agricultural enterprises in the south of the Yangtze River, such as Shanghai, have repeatedly introduced European cherries from Shandong, Dalian and other places for trial planting, but all showed slow germination, uneven germination, and ...

AI Technical Summary

Problems solved by technology

Taking a broad view of domestic and foreign sleep-breaking technology and the sleep-breaking agent adopted, there are following deficiencies: (1) although some chemical substances are better for breaking the dormancy effect of European cherry, they are harmful to human body and easily cause poisoning (as thiourea), There are residues after application, and organic or green product production cannot be carried out; (2) physical measures such as heating and temperature change are too costly, or are not feasible in actual operation, and are difficult to promote

Therefore, in the south of the Yangtze River, there is no successful product or technology for large-scale popularization and application of European cherry sleep-break technology.
