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.

Embodiment 1

[0018] 1. Prepare cyanamide solution. The crystalline cyanamide used in the present invention is packaged in a sealed container, kept dry and cool (25°C or lower), and the temperature must not exceed 45°C under any circumstances. When stored below 10°C, the shelf life is about 1 year. Its packaging method is a sealed polyethylene bag, plus a metal bucket. In the present invention, the crystalline cyanamide is added with water to prepare a solution with a mass concentration of 50% before use, and can be sealed and packaged with 202 and 304 stainless steel, glass, polyethylene, and polyester materials, and stored in a dry environment below 25°C for future use. The shelf life is about 6 months.

[0019] 2. Preparation of penetrant: The penetrant JFC used in the present invention is yellowish to colorless viscous liquid under natural conditions, generally packed in 200kg iron drum and 50kg plastic drum, stored as general chemicals, with a shelf life of 2 years. In the present i...

Embodiment 2

[0026] Before the hypnotic treatment, the preparation of the cyanamide solution and the penetrating agent were the same as in Example 1.

[0027] The germination period of European cherries cultivated in Jinhua, Zhejiang is generally in late February, so choose sunny weather around February 1 with a temperature between 10 and 24°C for treatment.

[0028] Use a graduated cylinder to measure 600ml of cyanamide solution with a mass concentration of 50% and add it to a 15L knapsack sprayer, then use a graduated cylinder to measure 75ml of a JFC solution with a mass concentration of 10% and add it to the same sprayer, add water to a safe water level Wire. At this time, the final mass concentrations of cyanamide and JFC were 2% and 0.05% respectively, and they were applied after being fully stirred. Seven days after the first treatment, that is, the second treatment was carried out around February 7 to consolidate the effect of the first treatment.

[0029] The dormancy-breaking m...

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 ...
