Problems solved by technology

However, the report did not pretreat the seeds. The seeds may have problems such as insufficient after-ripening, large consumption in the post-ripening process, and decreased vitality. There are also problems that the seeds absorb the treatment agent low and the soaking time is long, which is still difficult to meet. Require

Embodiment 1

[0027] The seed germination test (GB / T3543,4) is carried out by the Petri dish filter paper method, including the following steps:

[0028] 1. Seed material: select cabbage-type winter rapeseed varieties (such as WXM-1, DQW-1, wYw-1), the same type of seed material in the same comparison test, and the quality of the seeds is comparable;

[0029] 2. Select the petri dish for the test, and set the test group and control group 1-4, the test group number is A, and the control group numbers are B1, B2, B3, B4 in turn;

[0030] 3. For the numbered petri dishes, randomly select seed materials of the same variety, model and quality, with 100 seeds in each group;

[0031] 4. Seed treatment

[0032] ① The seed treatment method of the test group, including the following steps:

[0033] 1) Dry the fresh rapeseed in the shade to a water content of 12-15%, spread it on a bamboo mesh screen in the storage room, and control the indoor temperature at 15°C, light intensity of 2000lx, relative...

Embodiment 2

[0059] In 2015, a field test was carried out in Kongtong District, Pingliang.

[0060] 1. Experimental field preparation: select a river valley with deep soil, loose and fertile, and suitable water. After the previous crops are harvested, apply 2600-3000kg / mu of decomposed farmyard manure, and plow the soil 25-30cm deep, and then apply 20-25kg of urea / mu, superphosphate 40-50kg / mu, and rake after the rainfall, so that the ground is flat, the soil is soft, and the upper part is virtual and the lower part is solid;

[0061] 2. Seed material: select Chinese cabbage-type winter rape varieties such as WXM-1, and process them as follows:

[0062] 1) Dry the fresh rapeseed in the shade to a water content of 12-15%, spread it on a bamboo mesh screen in the storage room, and control the indoor temperature at 15°C, light intensity of 2000lx, relative air humidity of 30% and oxygen content of 5%, 10% carbon dioxide, fully matured for 10 days;

[0063] 2) Mix the fully post-ripened see...

Abstract

The invention discloses a seed treatment method for promoting early germination of rape. The method comprises the following steps: 1) drying fresh rape seeds in shade until the moisture content is 12%-15%, sealing the seeds in a storage room, and controlling the temperature, humidity, light, oxygen and carbon dioxide for full post-ripening for 5-12 days; 2) sanding and roughening the fully post-ripened seeds, and gently rolling the seeds to obtain the roughened seeds; 3) immersing the roughened seeds in a potassium polyacrylate aqueous solution and a sodium borate and boric acid buffer solution sequentially for treatment, rinsing the seeds with distilled water 2-3 times, and performing dewatering and drying in a dry and ventilated place until the moisture content is 10%-12%; 4) immersing the dried seeds in magnetized water for 2-3 hours, taking out and drying the seeds in the shade until the water content is 30%-35% and sowing the seeds. With adoption of the method for treatment, germination and emergence of the rape can be obviously promoted, the emergence rate and the seedling rate of the rape seeds can be increased, the rape seedlings grow robustly and have low incidence rate, rhizomes grow and are thickened obviously year-on-year, and the environmental requirements of rape seed germination are further reduced.

Description

technical field [0001] The invention belongs to the technical field of rapeseed treatment, in particular to a seed treatment method for promoting early germination of rapeseed. Background technique [0002] Seed treatment refers to various physical, chemical or biological treatment measures performed on seeds before sowing in order to promote fast and neat seed germination, vigorous growth of seedlings, prevent and reduce pests and diseases, or promote early maturity of certain crops. Seed treatment can not only reduce the decline in seed vigor during growth, harvesting and storage, but also restore seed vigor to a certain extent, kill seed-attached germs, prevent the occurrence of seedling pests and diseases, and improve the absorption and absorption of nutrients by seedlings. Utilize it to promote growth and development, so as to achieve the purpose of complete seedlings, uniform seedlings, strong seedlings and increasing production. [0003] Seed treatment in a broad sen...
