Problems solved by technology

In the seedling raising and planting of seedlings, the root system of seedlings cannot take root due to improper seed treatment, geological soil compaction, poor water permeability or impermeability; or due to drought, less rain, low temperature, low air humidity and other reasons, the survival rate of seedlings is low. , which has brought unprecedented difficulties to forestry, how to improve the survival rate of afforestation is a problem facing reality

Abstract

The invention provides a seedling-raising method for increasing the survival rate of seedlings. The method comprises the following steps of 1, seed treatment and 2, seedling raising. The seed treatment comprises the steps that 1, seeds are put into warm water of 50-55 DEG C, seed warming is conducted for 10-15 minutes, stirring is continuously conducted during the period, and impurities and shrivelled seeds are removed; 2, the seeds are soaked in a disinfection and sterilization solution for 3-5 hours and then taken out, and the seeds are cleaned with clear water until the surfaces of the seedling seeds have no mucilage; 3, after the seeds soaked in the step 2 are irradiated by an ultraviolet lamp for 10-20 minutes, the seeds are soaked in a salicylic acid solution with the concentration of 40 mg / L for 4-6 hours; 4, the seeds are wrapped with a wet towel which is soaked with gibberellin, a germination agent and a plant growth regulator, the wrapping thickness is 1-1.5 cm, the seeds are put in a constant-temperature box of 21-26 DEG C to be stored for 10 days, then the temperature of the constant-temperature box is set to be 2-4 DEG C, and storage is conducted for 15 days. Seedling raising comprises the steps of 1, preparing a seedling-raising matrix and 2, sowing the seedlings. By the adoption of the seedling-raising method for increasing the survival rate of the seedlings, the seed germination rate and bud germination rate of the seedlings can be increased, and the survival rate of seedling planting is increased.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a seedling raising method for improving the survival rate of seedlings. Background technique [0002] The technology and method of seedling planting should be widely used in garden engineering. In order to improve the ecological environment, my country has successively launched key projects such as Tianbao, Sanbei, and returning farmland to forests in the past ten years, and the forest coverage rate has increased year by year. In terms of forestry afforestation, since key projects with good site conditions have been given priority, most of the remaining implementation plots are arid places with poor site conditions. In the seedling raising and planting of seedlings, the root system of seedlings cannot take root due to improper seed treatment, geological soil compaction, poor water permeability or impermeability; or due to drought, less rain, low temperature, low air...
