Embodiment 1

[0012] Choose a plot with convenient irrigation and drainage and fertile soil, and plow more than 30cm deep before winter. On March 10 of the following year, plow about 30cm deeper, apply base fertilizer, and apply 5000kg of manure per mu, 30kg of superphosphate and 150kg of plant ash at one time, and then create ridges with a distance of 85cm and a height of 12cm. Rake the ridge surface and open two small ditches on the ridge surface with a distance of about 35 cm and a depth of 7 cm. Then water the small ditch, rake it again, spray herbicides, and cover the film to increase the temperature. On March 15th, when the ground temperature at a depth of 5 cm in the ridge was stable at 12°C, the two ridges were drilled and sown on the small ditch lines on the surface of the ridge, with a plant spacing of 15 cm and single seed sowing. When the seedlings are just exposed to the soil on March 25, the seedlings should be released in time to prevent aphids during the flowering period. ...

Embodiment 2

[0016] Choose a plot with convenient irrigation and drainage and fertile soil, and plow more than 30cm deep before winter. On March 15th of the following year, plow about 30cm deep again, spread base fertilizer, apply the standard of 5000kg manure per mu, 30kg superphosphate and 150kg plant ash at one time, and then create ridges with a distance of 85cm and a height of 12cm. Rake the ridge surface and open two small ditches on the ridge surface with a distance of about 35 cm and a depth of 7 cm. Then water the small ditch, rake it again, spray herbicides, and cover the film to increase the temperature. On March 20, when the ground temperature at a depth of 5 cm in the ridge was stabilized at 14°C, holes were drilled and sowed on the small ditch lines of the original two ridges, with a plant spacing of 15 cm and single seed sowing. When the seedlings are just out of the soil on March 28, the seedlings should be released in time. Prevent aphids during flowering. On June 15, 4...

Abstract

The invention provides a quick peanut propagation method, which comprises the following steps of: (1) preparation before sowing: selecting a plot convenient for drainage and irrigation and fertile, deeply tilling the plot before winter, deeply turning the plot in the first ten days of next March, applying a base fertilizer, ridging, raking the ridge surface, forming two ditches on the ridge surface, watering, raking, spraying herbicide, and covering a film to increase the temperature; (2) sowing of a first season: drilling holes for sowing on the original two ditch lines of the ridge surface in the middle ten days of March, sowing single seeds, releasing seedlings in time when the seedlings just come out of the soil in the last ten days of March, harvesting and drying the peanut serving as seeds of a second season when the peanut is 80 percent mature in the last or middle ten days of June; and (3) sowing of the second season: covering a film for cultivating the peanut from the last ten days of June to the first ten days of July in a plot where wheat is just harvested, sowing the seeds in the same mode as that in the first season, and harvesting and drying the peanut in the first or middle ten days of October. The propagation coefficient of the peanut seeds can reach over 50 times, and is improved by 250 percent compared with a traditional method; and the method has remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to a rapid propagation method of a new peanut variety, which belongs to the technical field of peanut breeding. Background technique [0002] Peanut is an important oil crop and economic crop in my country, which plays an important role in adjusting the rural industrial structure and increasing farmers' income. However, the amount of peanut seeds used is very large. The amount of seeds used for large peanuts is about 25 kilograms per mu, and the amount of seeds used for small peanuts is about 20 kilograms per mu. 10% of the total peanut production is used to reserve seeds. The Huanghuaihai area is the main peanut production area in my country, and the peanut planting area accounts for more than 65% of the national peanut area. However, peanuts are planted for one season in the Huanghuaihai region, and the breeding coefficient of peanut varieties is very low. At present, the single-seed sparse sowing, high-yield and high-multipli...
