Description
Technical Field
The invention belongs to the technical field of cherry planting, and particularly relates to a rapid germination and seedling raising method for sweet cherry seeds in south.
Background
Sweet cherry (Prunus avium) belongs to Rosaceae (Rosaceae) Prunus (Prunus) Cerasus (Cerasus) Laurera, and is called as early spring first fruit. The sweet cherry is a famous cherry and is originally produced along the coast of the European black sea and in the western Asia. In recent years, sweet cherries develop rapidly in southern areas, but cherry varieties suitable for being planted in the southern areas have certain limitations in adaptability, more sweet cherry varieties suitable for being planted in the southern areas need to be selected, and seedling selection is a main mode for selecting new sweet cherry varieties at present.
The sweet cherry seeds are not easy to germinate, the seeds can germinate only by being stored in sand for 4-5 months at low temperature, and the germination rate is low. In the south, the sweet cherry seedlings are seriously influenced by high temperature and humidity in summer. These problems severely restrict the process of breeding new variety of south sweet cherry.
The Chinese invention patent application (publication No. CN105284234A, published: 20160203) discloses a method for improving the germination rate of sweet cherry seeds. The method adopts a technical means of breaking shells and breaking dormancy at low temperature, promotes core-shell cracking, increases seed coat permeability, and is beneficial to decomposition or conversion of inhibiting substances in seed coats. The barrier of the core shell is broken through the seeds after the mechanical shell breaking, and the germination rate can be greatly improved after the seeds are treated at low temperature. The method has strong operability, does not need to remove seed coats, is suitable for large-scale treatment, is slightly influenced by the outside, has high germination speed, does not need hormone medicines such as gibberellin and the like, has the germination rate of over 95 percent, can improve the germination rate by 50 to 80 percent compared with the existing sand-storage stratification treatment method, and has the germination rate of over 90 percent. However, the method needs low-temperature and wet treatment for 90-120 days, and is not beneficial to the rapid breeding of the new variety of the sweet cherries in the south.

The organic-inorganic mixed matrix adopted by the application fully exerts the air permeability and water retention capacity of the perlite, the vermiculite and the turf, and provides enough nutrient substances for seed germination.
Preferably, the GA concentration is 800-2000mg/L, and the 1L mixed matrix addition amount is 50-200 mL. Preferably, the pregermination hormone is GA +6-BA solution; GA in mass ratio: 6-BA 80-150: 1-2. Most preferably, 80-120 mLGA +6-BA solution is added into 1L of mixed matrix, and the GA +6-BA solution contains 1000mg/L of GA and 10mg/L of 6-BA. The germination accelerating hormone used in the application plays a role in breaking dormancy of seeds and promoting germination by GA and 6-BA.
Further, the application also discloses a sweet cherry seed rapid seedling method, which comprises the following steps:
1) the method obtains the sweet cherry seeds and seeds are sowed in a forest seedling culture hole tray,
2) placing the plug tray in an illumination incubator, controlling the illumination at 6000lx, the temperature at 22-23 ℃ and the humidity at 60-70%, and spraying the 800-fold hypersensitive protein immune preparation once every 7 days;
3) and transplanting the seedlings into a beauty planting bag for management when the height of the seedlings is 6-10 cm.
This application is owing to adopted foretell technical scheme, and this application's advantage is: selecting sweet cherry seeds in the fruit coloring period, wherein the seeds have higher activity and higher germination rate; the seeds sprout and grow seedlings with the shells, the influence of substances such as hormones on the seeds is reduced, the seeds sprout under the state close to the natural state, and the resistance of the seedlings in the later period is stronger. This application carries out vernalization through vernalization hormone in organic inorganic mixed matrix, obtains the seed that sprouts fast, and the seed vigor is higher, and the germination rate is higher.
