Embodiment 1

[0020] 1. Slotting

[0021] (1) Slotting bed specifications The slotting bed is extended from east to west, 10-15m long, 1.2m wide, and 0.5m apart between the two beds. The bed surface is slightly higher than the original ground surface, and the bed soil is finely divided, loose and flat.

[0022] (2) Slotting bed matrix The matrix of the surface layer of the bed surface is mainly peat, supplemented by fine sand, with a volume ratio of 3:1, mixed well, and spread on the surface of the slotting bed with a thickness of 5-8cm.

[0023] The maturity of the peat should be small, and the sand should be silty. The matrix prepared by the two has good air permeability and water retention.

[0024] 2. Shed

[0025] The arch shed can be made of iron bars, and its height is 0.6m, width 1.3m, and length 3m. This arch shed is durable and easy to move. Bamboo splits can also be used to make sheds. The arch shed is covered with double-layer plastic shed film. Further up, a shade shed is s...

Embodiment 2

[0048] Embodiment 2: The cutting time is selected in the middle and late June, and compared with embodiment 1, only the cutting period is late, and the remaining operations of the seedling raising process are the same as in embodiment 1. If the cutting time is too late, the seedlings will be very small, so you can live through the winter directly on the seedbed without seedlings. Before overwintering, pour frozen water in late October, cover with straw or weeds after a few days, remove the cover in the next spring (late April), grow on the spot for 1 year, and transplant or transplant in the autumn of that year or the next spring. Colonization.

Abstract

The present invention relates to green branch cuttage breeding method for grassland cherry, and belongs to asexual propagation technology of plant. Cutting shoot is taken from available grassland cherry mother tree. The green branch cuttage breeding method includes the following steps: preparing cuttage bed with turf and sand as medium and covering double-layer arched sunshading film; cutting shoot from the mother tree and setting inside water in some container for inserting; regular watering after inserting, maintaining the humidity and ventilation and sunshading to promote growth; weeding, preventing disease and pests; and winter management. The method has high seedling survival rate.

Description

【Technical field】 [0001] The invention relates to the technical field of asexual propagation of prairie cherry, in particular to a green branch cutting propagation method of prairie cherry. 【Background technique】 [0002] Grassland cherry (Cerasus fruticosa) belongs to the Rosaceae cherry plant, native to the eastern, central, and Siberian areas of Europe. Its introduction and cultivation in my country began in 1988. It was introduced by the Department of Horticulture of Northeast Agricultural College from the Institute of Horticulture in Siberia, Russia. ', 'Maximovskaya' and other varieties, through more than ten years of research and observation, grassland cherries have shown strong adaptability, good growth and development, no freezing damage, no pests and diseases when cultivated in open field in many places in cold regions. The plant height of "Hope" is about 2m, and the weight of a single fruit is about 4g; the plant height of "Maximovskaya" is about 1.5m, and the sing...
