Embodiment 1

[0039] The method for cultivating ratooned rice provided by the invention comprises the following steps:

[0040] 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

[0050] The method for cultivating ratooned rice provided by the invention comprises the following steps:

[0051] 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 ratooning rice and seeds of ratooning rice. The method comprises: soaking the conventional upland rice as the female parent and soaking the seeds with biological medicine; accelerating the germination, putting the seeds into a sterilized cloth bag, covering the heat-insulating layer and placing them in the sun for exposure; And keep it warm at 20-30°C, pour warm water 2-3 times a day in the morning and evening to accelerate germination until the seeds germinate; sow, spread the germinated seeds evenly on the prepared soil, and cover with aseptic plant ash; cultivate, to the sowing area Water 1-2 times in the morning and evening, until the seedlings grow 3-5 tillers, transplant the seedlings to the field where the wild rice has been transplanted 5 days ago, plant and cultivate until the rice is mature, and the wild rice is planted every 5 days. 2 rows, planting 3 rows of upland rice; seed selection, selecting seeds from the harvested rice ears, and continuing to use the above-mentioned steps to hybridize the selected seeds in the coming year, so as to obtain hybrid seeds through multi-year hybridization. The invention aims to solve the time-consuming and labor-intensive drawbacks caused by non-renewable rice in the existing rice 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. 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, the traditional rice planting method is time-consuming. Therefore, it is necess...
