Cherry seedling culture method

[0015] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] As attached figure 1 As shown, the cultivation method of cherry seedlings includes the following sequential steps: collecting rootstock seeds 1, rootstock seed planting soil pretreatment 2, rootstock seed treatment 3, rootstock seed planting 4, rootstock management 5, and cherry branch grafting 6.

[0017] In the specific implementation process, the rootstock seed 1 is collected before and after the first year of the cold. The outer flesh of the wild cherries is removed and cleaned, and the cherry pits are dried and placed in a dry and ventilated place as seeds for planting rootstocks for preservation. Pretreatment of the rootstock seed planting soil 2 is to first deep plow the soil to be planted in the spring of the second year; then spray and disinfect the deep plow soil with quicklime water and then perform shallow rotary plowing. In the specific implementation process, spray disinfection is performed according to the amount of 100kg quicklime used per mu of land. Rootstock seed treatment 3 is to soak wild cherry cores in sterilized spring water for 3 days 8 days before planting; then remove the cherry cores to drain the surface of the cherry cores, and wrap the cherry cores with plastic film and place them at 18°C It was stored for 3 to 5 days at an ambient temperature of ~25°C, and it was stored for 4 days during the specific implementation of this case. Rootstock seed planting 4 is to ditch the sterilized soil with a line spacing of 30 cm, and the ditch depth is greater than 20 cm; the ditched soil is exposed to the sun for 8 to 10 days; then two plants are planted at an interval of 10 cm. Grain cherry pits, the thickness of the cover soil during cherry pit planting is 10cm-12cm; then watering, using plastic film to cover the cherry pit planting row; subsequent watering every 10 days until the seedling emerges. Rootstock management after emergence 5 is to dissolve the compound fertilizer in water every 15 days for fertilization, after 3 to 4 times of fertilization; subsequent watering and fertilization every one month interval, continuous for 3 to 4 months; It grows to 60cm~80cm tall. Cherry branch grafting 6 is to cut the rootstock body and thin skin 20cm above the root of the rootstock in the third spring, and graft the cut cherry branches to form cherry seedlings.

[0018] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and modifications to these embodiments still fall within the protection scope of the present invention.
