Embodiment 1

[0041] The method for cultivating ratooned rice provided by the invention comprises the following steps:

[0042]Step S10: Seed soaking. In the Grain Rain season, conventional upland rice is used as the female parent to soak the seeds with biological medicine for 24 hours. Every jin of seeds is soaked in 2 jin of biomedicine, wherein the female parent is Shicanian conventional rice. Wherein, the biomedicine is prepared by boiling Guangui, Codonopsis pilosula, Wuyao, rabbit silk, Radix Polygonum multiflorum and Rhizoma Polygonatum with water for 2.5 hours. The mass fraction of the Guangui is 15 parts, the mass fraction of the Codonopsis pilosula is 14 parts, the mass fraction of the black medicine is 6 parts, the mass fraction of the rabbit silk is 4 parts, the mass fraction of the The number of parts by mass of Radix Polygoni Multiflori is 22 parts, the number of parts by mass of Polygonatum is 13 parts, and the number of parts by mass of water is 90 parts.

Embodiment 2

[0052] The method for cultivating ratooned rice provided by the invention comprises the following steps:

[0053] Step S10: Seed soaking. In the Grain Rain season, the conventional upland rice is used as the female parent to soak the seeds with biological medicine for 26 hours. Every jin of seeds is soaked in 2.5 jin of biological medicine, wherein, the female parent is Shicanian conventional rice. Wherein, the biomedicine is prepared by boiling Guangui, Codonopsis pilosula, Wuyao, rabbit silk, Radix Polygonum multiflorum and Rhizoma Polygonatum with water for 2.8 hours. The mass fraction of the Guangui is 12 parts, the mass fraction of the Codonopsis pilosula is 13 parts, the mass fraction of the black medicine is 7 parts, the mass fraction of the rabbit silk is 4.5 parts, the mass fraction of the The number of parts by mass of Radix Polygoni Multiflori is 24 parts, the number of parts by mass of Polygonatum is 14 parts, and the number of parts by mass of water is 95 parts. ...

Abstract

The invention discloses a method for cultivating regenerated rice and regenerated rice seeds. The method includes soaking seeds: soaking conventional upland rice as a female parent with a biological liquid medicine; accelerating germination: putting the seeds into a sterilized cloth bag, covering an insulating layer, standing in the sun for insolation, keeping the temperature at 20-30 DEG C, pouring warm water 2-3 times every morning and evening to accelerate germination until the seeds germinate; sowing: evenly sowing the germinated seeds on the whole soil and covering sterile plant ashes; cultivation: watering the sowing area 1-2 times in the morning and evening respectively, transplanting the seedlings to the field where wild rice is transplanted 5 days ago until the rice is ripe, wherein wild rice is planted in each 2 rows and dry rice is planted in each 3 rows; and selecting seeds: selecting seeds from harvested rice ears, and continuing to hybridize the selected seeds by the above steps in the coming year to obtain hybrid seeds through multi-year hybridization. The method aims to solve the disadvantage of time-consuming and labor-consuming caused by non-renewable rice grainsin the existing rice grain planting method.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for cultivating ratooned rice and seeds of ratooned rice obtained by the method for cultivating ratooned rice. Background technique [0002] Rice is the main grain crop in China. Since ancient times, it has been said that food is the most important thing for the people; In recent years, the cultivated area of ​​rice has become less and less, and the cultivated area of ​​upland rice in the north is more than two or three times the cultivated area of ​​rice, and most of the places where water is scarce are barren and unsuitable for cultivation. However, rice remains one of the most important food crops. In the prior art, rice is not regenerative, so it is necessary to re-cultivate the land every year, and re-use seeds to cultivate seedlings and transplant seedlings. Therefore, it is necessary to buy new seeds every year, and repeat a lot of physical labor, that is, ...
