Peach tree sowing and seedling-raising method

Abstract

The invention relates to a peach tree sowing and seedling-raising method, and relates to the technical field of peach tree seedling raising. The method is characterized by comprising the following steps: seeds are collected; cold stratification is carried out, wherein a pit is dug at a high-dryness, well-drained, leeward and sunny place in October to November, stones are placed in the bottom of the pit. seeds are stratified on the stones; coarse sand is added on the seeds, 3-4cm of wet sand is spread on the coarse sand, 5-10cm of hay covers the wet sand, and the seeds are subjected to cold stratification for 60-80 days; germination accelerating is carried out before sowing, wherein un-germinated seeds after cold stratification are soaked with cold water for 3-5 days before sowing, wherein water is changed once a day, the soaked seeds are exposed to the sun at a sunny place for 2-3h every day, and are then stacked and covered for thermal insulation and moisture preservation; sowing is carried out, wherein before sowing, soil is sterilized by using a 1:500 water solution of potassium permanganate, and after sowing, when 2-3 pairs of true leaves appear on each seedling, the seedlings are transplanted into nursery containers; and seedling-stage management is carried out. The method provided by the invention has high efficiency; sprout survival rate is high; and the method is easy to operate. The method is suitable for cultivating new varieties.

Description

technical field [0001] The invention relates to the technical field of peach tree seedling cultivation, and relates to a method for sowing and cultivating peach tree seedlings. Background technique [0002] Peach tree is a small deciduous tree whose fruit is used as fruit. The flowers can be viewed and admired, and the fruit is juicy. It can be eaten raw or made into preserved peaches, canned food, etc., and the kernels are also edible. The pulp is white and yellow, and there are many varieties of peaches. Generally, the skin is hairy, and the skin of "nectarine" is smooth; petal. The seedling raising method of peach tree all is to adopt the mode of grafting seedling raising of peach tree as rootstock at present, but the efficiency of existing seedling raising method is too low, and operation is more troublesome, and the budding rate of peach tree seed, and the success rate of peach tree grafting are all too low, cause And can't adopt the method for this grafting seedling ...
