Seed collecting method for improving Sophora davidii germination rate

Abstract

The invention discloses a seed collecting method for improving Sophora davidii germination rate. The method comprises the steps of: (1) taking Sophora davidii seeds about 60d after anthesis as materials, according to selection criteria, picking seed pods to take out seeds when the seed pod peels just turn to brown, if the seeds cannot be treated immediately, putting the seeds in a kraft paper bag or mixing them with wet river sand evenly, and then placing the seeds in the refrigerating chamber of a refrigerator for one week for standby use; and (2) soaking the seeds with 50-60DEG C warm water for about 4h, and then performing airing at room temperature, thus being able to conduct seeding. The method provided by the invention is simple and feasible, can be implemented only by recording the anthesis and observing the seed pod color change, and is safe, time saving and labor saving, and has stable effect compared with previous methods. Also, the method is in line with the national requirements for energy-saving and cost-reducing, and ecological security.

Description

technical field [0001] The invention relates to a method for collecting seeds of plants, in particular to a method for collecting seeds of Nitraria japonica. Background technique [0002] When the seeds of Nitraria japonica are fully mature, they are hard seeds. At present, the germination rate of common seeds is only about 20%. It can reach 80-90%, but the operation safety of concentrated sulfuric acid treatment is poor, the waste liquid treatment is troublesome, and improper treatment is easy to pollute the environment; mechanical friction is good for a small amount of seeds, but it is time-consuming and labor-intensive, or the treatment effect is inconsistent. Other methods such as GA treatment, sodium hydroxide treatment, potassium nitrate treatment, hydrogen peroxide treatment, hot water soaking, stratification treatment and other methods can improve the germination rate, but the improvement effect is not good. Contents of the invention [0003] The technical problem...

Problems solved by technology

[0002] When the seeds of Nitraria japonica are fully mature, they are hard seeds. At present, the general seed germination rate is only about 20%. It can reach 80-90%, but the operation safety of concentrated sulfuric acid treatment is poor, the waste liquid treatment is troublesome, and it is easy to pollute the environment if it is not handled properly; the treatment effect of a small amount of seeds by mechanical friction is better, but it is time-consuming and labor-intensive, or the treatment effect is inconsistent

Other methods such as GA treatment, sodium hydroxide treatment, potassium nitrate treatment, hydrogen peroxide treatment, hot water soaking, stratification treatment and other methods can improve the germination rate, but the effect of improving germination rate is not good.
