Technical Field
The invention relates to the technical field of agricultural planting, in particular to a method for cultivating dry rice seeds.
Background
Dry rice is also called upland rice. An ecotype crop formed by long-term domestication and evolution of rice under the condition of dry land without water layer. The method is suitable for cultivation in dry land and can also be used for cultivation in paddy field or low-lying land, and is mainly distributed in dry land and hilly land where rainwater is stable in summer but irrigation conditions are lacked, or low-lying area where water is easily flooded in spring and drought, summer and autumn. A small amount of cultivation is carried out in the rice areas in the south and north of China. The upland rice has the advantages of strong and luxuriant stems and leaves, wide leaves, light color, developed root system, more root hairs, higher osmotic pressure of roots and cell juice concentration of leaves, early and heat resistance and strong water absorption capacity. The yield is generally lower than that of rice, the rice yield is low, and the rice quality is inferior.
In order to meet the market demand, dry rice seeds with strong drought resistance and good rice quality need to be bred.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a method for cultivating dry rice seeds with strong drought resistance and good rice quality.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a cultivation method of upland rice seeds comprises the following steps:
(1) cultivating and domesticating first-generation rice seeds: seeding the rice seeds of the fragrant silk seedlings on 1-2 mu of dry land, and collecting the rice with the single plant yield not less than 37 g/plant in the mature period as the domesticated first-generation rice seeds;
(2) cultivating and domesticating second generation rice seeds: sowing the domesticated first generation rice seeds on a dry land of 3-4 mu, and collecting rice with the yield of not less than 40g per plant in a mature period as domesticated second generation rice seeds;
(3) and (3) breeding the target dry rice seeds: and (3) sowing the domesticated second generation rice seeds on 5-8 mu of dry land, and collecting the rice with the single plant yield not lower than 43g per plant in the mature period to obtain the dry rice seeds.
Preferably, when the 'fragrant rice seedling' in the step (1) is as long as 8 to 10 cm, a layer of dry rice straw with the thickness of 4 to 6 cm is paved at the root of the rice seedling.
Preferably, when the domesticated first generation rice seedling in the step (2) is as long as 8 to 10 cm, a layer of dry rice straw with the thickness of 3.0 to 3.5 cm is paved at the root of the rice seedling.
Preferably, when the domesticated second-generation rice seedling in the step (3) is as long as 8 to 10 cm, a layer of dry rice straw with the thickness of 1.5 to 2.0 cm is paved at the root of the rice seedling.
Preferably, brassinolide is sprayed when the ears of the upland rice are sprouted in the step (1), and the using amount of the brassinolide is 25-30 g/mu.
The invention has the beneficial effects that: the invention relates to a method for cultivating dry rice seeds, which comprises the steps of sowing fragrant silk seedlings on dry land, and cultivating the rice seeds into dry rice seeds which have stable drought resistance and can be suitable for land production through continuous domestication.
According to the method for cultivating the rice seeds of the dry rice, disclosed by the invention, the thickness of the rice straws laid on the roots of the rice seedlings is continuously adjusted in the process of acclimatizing the rice seeds into the rice seeds of the dry rice, so that the effect of adjusting the surface moisture evaporation speed of the dry land is achieved, the acclimation strength for acclimatizing the rice seeds into the rice seeds of the dry rice can be effectively controlled, the survival rate of the rice seedlings in the process of acclimating the rice is improved, and the stability of the drought resistance of the rice seeds of the dry rice is improved.
According to the method for cultivating the rice seeds of the upland rice, disclosed by the invention, the brassinolide is sprayed when the ears of the upland rice are pulled and the flowers are raised during the cultivation and domestication of the first generation rice seeds, so that the maturing rate of the upland rice can be improved, and more rice with high single plant yield can be cultivated to obtain the domesticated first generation rice seeds.
