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.
