Method for immersing corn seeds by combining rare earth element lanthanum with temperature variation

Abstract

The invention discloses a method for immersing corn seeds by combining a rare earth element lanthanum with temperature variation and belongs to the field of common breeding of plants. The method comprises the following steps: firstly, preparing a rare earth element lanthanum working solution with the concentration of 300ppm; putting corn seeds into a seed bag; after disinfecting at 50 DEG C for 10 minutes, immersing the seeds into the rare earth element lanthanum working solution according to the ratio of the mass of the seeds to the volume of the rare earth element lanthanum working solution of 1 to 5; and performing slow temperature variation treatment for 1 day at 20 or 30 DEG C; and putting the treated corn seeds into a germination box containing sand to germinate for 10 days at a constant temperature of 25 DEG C (12 hours in light and 12 hours in dark).

Description

technical field [0001] The invention relates to a method for soaking corn seeds in combination with rare earth element lanthanum at variable temperatures, which belongs to the field of conventional plant breeding. Background technique [0002] Corn is an important food, economic and feed crop with wide application and large demand, and occupies an important position in the national economy. Therefore, increasing corn production plays an important role in ensuring national food security, promoting animal husbandry and rural economic development, and increasing farmers' economic income. At present, domestic corn planting adopts the method of drill sowing and hole sowing, and most of the seeds are directly planted in the ground. The disadvantage of this method is that the seedling emergence and seedling time are inconsistent, and the lack of seedlings is serious, which brings huge troubles to corn production. Therefore, improving the rate of full seedlings, full seedlings and ...
