Embodiment 1

[0016] A method for cultivating black pine seedlings, comprising the following steps:

[0017] (1) Harvest mature seeds in the fruit ripening season first, select seeds with full grains and no cracks, and select them again after drying to ensure their survival rate;

[0018] (2) Seed treatment: first mix the black pine seeds with wet sand, freeze in an environment below minus 3°C for 25 days, then soak the black pine seeds in clear water for 4 hours, and then use 7% KH 2 PO 4 Soak in the solution for 2 hours, the soaking temperature is 25°C, after the seeds are sterilized, soak them in warm water at 50°C, stir them thoroughly for half an hour, let the water temperature drop to 20°C, soak for 1 day and night, take them out and put them in a basket or cover them with a damp cloth Put it in a warm place, add clear water to the soaked seeds and rub and wash, the degree of rubbing is that the waxy layer on the surface of the black pine seeds is destroyed, and it is sown into the s...

[0024] A method for cultivating black pine seedlings, comprising the following steps:

[0025] (1) Harvest mature seeds in the fruit ripening season first, select seeds with full grains and no cracks, and select them again after drying to ensure their survival rate;

[0026] (2) Seed treatment: first mix the black pine seeds with wet sand, freeze in an environment below minus 3°C for 30 days, then soak the black pine seeds in clear water for 3 hours, and then use 5% KH 2 PO 4 Soak in the solution for 5 hours, the soaking temperature is 28°C, after the seeds are sterilized, soak them in warm water at 55°C, stir them thoroughly for half an hour, let the water temperature drop to 25°C, soak for 1 day and night, take them out and put them in a basket or cover them with a damp cloth Put it in a warm place, add clear water to the soaked seeds and rub and wash, the degree of rubbing is that the waxy layer on the surface of the black pine seeds is destroyed, and it is sown into the s...

Embodiment 3

[0032] A method for cultivating black pine seedlings, comprising the following steps:

[0033] (1) Harvest mature seeds in the fruit ripening season first, select seeds with full grains and no cracks, and select them again after drying to ensure their survival rate;

[0034] (2) Seed treatment: first mix the black pine seeds with wet sand, freeze in an environment below minus 3°C for 40 days, then soak the black pine seeds in clear water for 1 hour, and then use 3% KH 2 PO 4 Soak in the solution for 7.5 hours, the soaking temperature is 32°C, soak the seeds in warm water at 60°C after disinfection, stir thoroughly for half an hour, make the water temperature drop to 30°C, soak for 1 day and night, take them out and put them in a basket or basket, cover them with a damp cloth and put them away In a warm place, the soaked seeds are rubbed and washed with clear water. The degree of rubbing is that the waxy layer on the surface of the black pine seeds is destroyed, and they are s...

Abstract

The invention discloses a lodgepole pine seedling growing method. The lodgepole pine seedling growing method comprises the steps of seed selection, seed treatment, seedling growing on a seedbed and seedling growing through sowing and the like. In the seed treatment process, low-temperature treatment is conducted on seeds firstly, then the seeds are treated through chemicals and warm water, in this way, the seeds can germinate in a shorter time, the defects that in the prior art seeds germinate slowly, and seedlings are not uniform are solved, and propagation of trees the seedlings of which are difficult to grow originally is made easy and fast; in addition, the germination rate is increased, and seed treatment cost is reduced. According to the method, a prepared lamination matrix is higher in breathability, in this way, the seeds can breathe easily, dormancy breaking of the seeds is accelerated, and germination of the seeds is facilitated by selecting the matrix.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a black pine seedling raising method. Background technique [0002] Black pine, also known as white bud pine, Japanese black pine, is an evergreen tree of the genus Pinaceae. Black pine grows fast, has strong wind resistance, sea fog resistance, drought resistance, barrenness, strong resistance to harsh weather, and has the effect of preventing wind and sand and maintaining water and soil. It is a pioneer tree species in the eastern part of my country to build coastal forests and coastal barren hills and beaches. The tree shape is tall and beautiful, evergreen, and it is also an ornamental tree species for garden greening. Timber can be used as ore pillars and building materials. Black pine is native to Japan and is cultivated in my country's Liaodong Peninsula, Shandong, Jiangsu, Zhejiang and Taiwan. Vertically distributed in the area below 600 meters above sea level in Shandong ...
