Method for hybrid seed production, flowering period coordination and field seedling preservation for millet

Abstract

The invention discloses a method for hybrid seed production, flowering period coordination and field seedling preservation for millet. Seedlings are cultured according to different staggered periods and different proportions of male and female parents and at suitable time in the hybrid millet seed production field, and during field planting, the seedlings are cultured at suitable time according toactual production demands. According to the method, by transplanting cultured millet seedlings, the hybrid seed production and flowering period coordination for the millet are achieved, a suitable seedling reservation density is adopted for millet planting, and the problems are solved that the flowering periods of produced hybrid millet seeds are not coordinated, the hybridization rate and the seed production rate are low, seedling emergence is difficult through direct seeding of traditional millet seeds in the field, lacking seedlings and seedlingless ridges are frequently caused, the per unit area yield of the millet in the field is seriously affected, varieties with a long growth period are planted, or the accumulated temperature of millet for multiple cropping is insufficient after preceding crops are harvested, and the planting enthusiasm of farmers is not high.

Description

technical field [0001] The invention relates to millet hybrid seed production and field millet cultivation technology, in particular to a millet hybrid seed production method for coordinating flowering period and field preservation of seedlings. Background technique [0002] Millet is one of the traditional and ancient cultivated crops in my country. It was called millet, millet, or beam in ancient times. It was the first of the "five grains" in ancient China. After peeling, commonly known as "millet", it is one of the main grains loved by people in northern China. Millet is one of the traditional and ancient cultivated crops in my country, with a cultivation history of at least 7,000 years in China. It has the characteristics of drought tolerance, barren resistance, and rich nutrition. For thousands of years, it has not only nurtured the Chinese descendants, but also played an important role in the gestation, formation and development of Chinese civilization. [0003] Ch...

Problems solved by technology

[0006] The purpose of the present invention is to provide a method for coordinating the flowering period of millet hybrid seed production and preserving seedlings in the field, through millet cultivation and transplanting of seedlings, to realize the coordinated flowering period of millet hybrid seed production and suitable seedling density for millet planting, and to solve the uncoordinated flowering period of hybrid millet seed production , the hybridization rate and seed production yield are low, and the traditional millet seeds in the field are directly broadcast, and it is difficult to emerge, which often results in lack of seedlings and broken ridges, which seriously affects the yield per unit area of ​​field millet. Insufficient and farmers' low enthusiasm for planting
