Problems solved by technology

Although this method is simple, the soaking time is too long, and the water temperature and time of soaking are not well controlled. It is easy to cause the seeds to lose activity due to too high soaking water temperature or too long time, thus affecting the germination rate of cotton seeds.

Abstract

The invention discloses a cotton seed germination accelerating method, which comprises the following steps of 1, seed selection; 2, sterilization and disinfection; 3, cleaning; 4, seed soaking; 5, germination acceleration (soaked cotton seeds are coated by a towel and are then made into a germination accelerating seed bag; next, the seed bag is put onto a small-hole sieve screen; hot air being 35to 40 DEG C vertically blows through the seed bag from a position under the sieve screen; after 1 to 3h, the seed bag is put into a microwave processor; a layer of pad material being 3 to 5cm in thickness is uniformly laid on the bottom of the seed bag; next, the seeds are subjected to microwave treatment for 15 to 30s; finally, the seed bag is put onto the small-hole sieve screen; 6, culture. Thecotton seed germination accelerating method provided by the invention solves the problems of low cotton seed germination rate and poor young seedling survival rate; the emergence rate is improved; the strong seedling and healthy seedling rate is ensured.

Description

technical field [0001] The invention belongs to the technical field of seed treatment, and in particular relates to a method for accelerating germination of cotton seeds. Background technique [0002] The seed coat of cotton seeds is tough and covered with a layer of short fleece. If dry seeds are sown directly, their germination will be affected in drier soil, which will inevitably cause some seeds to germinate late. Thereby the growth speed of seedlings is different, which will affect the flowering and boll setting and mature harvesting of cotton in the future. Seed soaking and accelerating germination are conducive to sowing all seedlings at once, and early emergence and early development. The traditional method is to soak the seeds in cold or warm water. After the soaking, wrap the seeds with plastic cloth or towel, and then germinate them in an environment of 30-35°C. After most of the seeds sprout, they are sown. Although this method is simple, the soaking time is t...
