Abstract

The invention provides a high mountain dry rice cultivation method, and relates to the field of dry rice protection original seed cultivation. The high mountain dry rice cultivation method comprises the following steps: S1, selecting seeds: selecting dry rice seeds in an original rural alpine region, which are low in yield and serve as initial seeds, and then preparing to pre-treat the seeds to prepare for sowing; s2, obtaining a female parent: planting the selected seeds to ensure that the planted seeds grow normally in a natural environment, so that the initial seeds are selfed for 3-5 generations, and then selecting the seeds which grow stably and are excellent in quality as female parent seeds. According to the cultivation method, through hybridization of the dry rice and the reed imperata cylindrical powder, the rice planted by the cultivated dry rice has excellent quality of drought resistance, cold resistance, strong virus and insect pest infection resistance and thick and hardrhizomes of a wild original variety, and the reed imperata cylindrical is not dead in nature and has stubborn vitality.

Description

technical field [0001] The invention relates to the technical field of upland rice cultivation, in particular to a method for cultivating alpine upland rice. Background technique [0002] Upland rice is also called upland rice. It is an ecological crop formed by the long-term domestication and evolution of rice under dry land conditions without water layer. It is suitable for cultivation in dry land, and can also be planted in paddy fields or depressions. It is mainly distributed in dry lands and hillsides with stable summer rainfall but lack of irrigation conditions, or low-lying areas where spring droughts are prone to waterlogging in summer and autumn. There is a small amount of cultivation in the north and south rice regions of my country. [0003] Rice is one of the most important food crops for human beings, and it has a long history of cultivation and consumption. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America and parts ...
