Problems solved by technology

In recent years, due to the short supply of large-scale white-bark pine seedlings, there is a broad market space for cultivating strong seedlings and large seedlings. However, due to the lack of scientific seedling cultivation and management, white-bark pine seedlings still have a low survival rate and a low rate of strong and large seedlings.
Bring certain difficulties to whitebark pine growers

Embodiment 1

[0015] A kind of seedling cultivation method of white bark pine, comprises the following steps:

[0016] 1) Choose a good nursery: choose a flat plot with drainage and irrigation conditions, not a land with heavy clay or saline;

[0017] 2) Soil preparation: deep plowing, leveling and raking, applying sufficient base fertilizer or mixing calcium superphosphate with cake fertilizer or soil miscellaneous fertilizer, spreading 10 kg of ferrous sulfate powder per mu before land preparation, turning it into the soil for sterilization and disinfection, the land After finishing, make a north-south border field with a height of 25 cm and a width of 1 meter for sowing;

[0018] 3) Seed germination treatment: soak and sterilize the pine seeds with Bordeaux mixture, soak the seeds at a water temperature of 50°C or mix with sand to accelerate germination;

[0019] 4) At the beginning of late March, wide-width drilling or broadcasting is adopted, and 1 cm of fine sand is covered after sow...

Abstract

The invention belongs to a seedling culture method and particularly relates to a seedling culture method of lacebark pine, which is provided aiming at the current situation of low survival rate, strong seedling rate and large seedling rate. According to the seedling culture method, a seedling land is selected from a whole flat land which can be drained and irrigated, the seedling land is turned deeply, flattened and refined by raking, base fertilizers are sufficiently supplied to the seedling land, 10kg of ferrous sulfate powders are applied to each mu of the seedling land before land preparation and are buried into the soil to sterilize, and seeds need to be subjected to bud forcing treatment. A bordeaux mixture is used for soaking and sterilizing the seeds, before being sown, the seeds are soaked by warm water (50 DEG C-60 DEG C) or are accumulated in a sand mixing layer, so that bud forcing is conducted, after the soil is thawed for 15 days, 1-1.5kg of seeds are sown for each 10m2 of land, 1500 seedlings can be produced, the large seedlings can be cultured, and the seedlings can be transplanted for 2-3 times before planting. According to the seedling culture method, the survival rate and the strong seedling rate are high.

Description

technical field [0001] The invention belongs to a method for raising seedlings, in particular to a method for raising seedlings of pine pine. Background technique [0002] White bark pine is an evergreen tree with whorled branches, prominent winter buds, many bud scales, many scales, and arranged in imbricate shapes. There are needles on the twigs, and the needles are born on the nodular leaf pillows at the intersection of branches and leaves. The cones mature in the autumn of the second year. It is one of the unique tree species in China, with various tree shapes, tall and straight green, and unique characteristics. It is an excellent tree species for urban and garden greening. In recent years, due to the short supply of large-scale white-bark pine seedlings, there is a broad market space for cultivating strong seedlings and large seedlings. However, due to the lack of scientific seedling cultivation and management, white-bark pine seedlings still have a low survival rate ...
