Embodiment 2

[0057] (1) Preparation of initiator: calcium chloride 5g / L, chitosan oligosaccharide 15g / L, sucrose 5g / L, proline 2g / L.

[0058] (2) Soaking of Brassica napus seeds in an initiator: put the Brassica napus seeds in a glass container, add the prepared initiator, and the dosage of the initiator is 3 times the mass of the seeds. The container was placed in a dark incubator at 20° C. for 12 h, during which it was stirred slowly 3 times.

[0059] (3) Re-drying treatment of Brassica napus seeds: Take out Brassica napus seeds and wash them with distilled water for 20 seconds, filter off excess water, blot dry with absorbent paper and put them in a blast drying oven at 25°C to keep the moisture content of Brassica napus seeds at 9%, the dried seeds should be stored in a light-proof environment below 4°C. This processing is denoted as T2.

Abstract

The invention provides a brassica napus seed initiator, an initiation method and application, and relates to the technical field of seed treatment. The raw materials of the initiator comprise common calcium chloride, chitosan oligosaccharide, cane sugar and proline. The invention further provides a seed initiation method matched with the initiator, seed initiation treatment is easy to operate, low in cost, environmentally friendly and efficient, and the seed initiation method is well matched with an existing cultivation mode. Compared with seeds not subjected to seed priming treatment, after brassica napus seeds are subjected to priming treatment, the germination rate and the seedling emergence rate are increased under the drought condition, seedlings emerge neatly, the growth cycle of brassica napus is shortened, the crop rotation contradiction is relieved, the planting area is enlarged, the seedling emergence rate can be increased by 13.7%, the dosage of the seeds and the coating agent is saved by 20.9-25.4%, and the yield is improved by 18.1%.

Description

technical field [0001] The invention belongs to the technical field of seed treatment, and in particular relates to an initiator of Brassica napus seeds, an initiator method and an application thereof. Background technique [0002] Rapeseed (Brassica napus L.) is the world's largest oil crop, not only the main source of edible oil, but also an important industrial raw material and protein feed. Rapeseed is an important oil crop in my country. The planting area and total output of rapeseed in my country ranks second in the world, second only to Canada. In 2015, the total sown area of ​​rapeseed in my country was 7.534 million hectares, with a total output of 14.93 million tons, accounting for 42.2% of the total output of oilseed crops. [0003] Water shortage is a global problem that restricts agricultural development. Its harm ranks first among all abiotic stresses. It has the greatest impact on agricultural production and is also one of the factors that are difficult to im...
