Embodiment 1

[0019] In February 2020, a blueberry sleep-break experiment was carried out in an indoor environment with artificial light. The variety tested was 'Misty' four-year-old seedlings, which were planted in a mixed substrate including but not limited to peat soil and perlite. The concentrations of cyanamide used as a sleep breaker in the test were T1: 0.45%, T2: 0.5%, and T3: 0.65%. The specific test steps are as follows:

[0020] (1) The blueberry seedlings will accumulate low temperature (less than 7.2°C) for 300 hours until January 1, 2020, and gradually increase the temperature to 15°C-20°C within 7-10 days, the light intensity is 200μmol / ㎡·s, and the sunshine length is increased to 10 -12 hours, the air relative humidity is controlled at 60%-70%. At this time, the blueberry enters the dormancy budding period, and the flower buds germinate one after another in late January, but the leaf buds do not germinate.

[0021] The suitable light environment and supporting management ...

Abstract

The invention discloses application of cyanamide as a dormancy breaking agent in breaking dormancy of indoor cultivated blueberry leaf buds, and solves the problems that blueberries do not sprout or blossom and spread leaves irregularly when the cooling capacity of the indoor cultivated blueberries does not meet the cooling capacity required by varieties.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to the application of cyanamide as a dormancy-breaking agent in breaking dormancy of indoor cultivated blueberry leaf buds. Background technique [0002] Blueberry is a plant belonging to the genus Vaccinium of Rhododendronaceae, a perennial shrub with small berries and deciduous or evergreen fruit trees. Because its peel and pulp contain a large amount of biologically active substances such as anthocyanins, vitamins, and flavonoids, it has the unique effects of preventing brain aging, enhancing heart function, preventing visual fatigue, and preventing cancer. It is recommended by the Food and Agriculture Organization of the United Nations. One of the top five healthy fruits. [0003] In order to achieve the goal of blueberry fruit going on the market early, in production, the blueberry flower buds are often given the shortest amount of cooling required and...
