Description
Technical Field
The invention belongs to the technical field of rice production. More particularly relates to a hypoxia-resistant seed soaking agent for water-flooded direct-seeding rice and application thereof.
Background
With the mass transfer of rural age-appropriate labor, the labor cost of agricultural production is rapidly increased, and the agricultural technology is simplified, especially the agricultural technology is simplified, so that the urgent need for agricultural production is brought about. A novel green and light simplified rice production mode such as a perennial rice technology, a rice water flooding direct seeding technology and the like also has been developed.
The paddy water flooding direct seeding technology is a seeding mode that after paddy field tillage and base fertilizer application are completed, a water layer of 3-5 cm is reserved in the paddy field, the immersed and expanded rice seeds are uniformly sowed in the paddy field, and the paddy field is kept flooded for about 15d after sowing, so that the rice seeds germinate under water to form seedlings. The paddy rice water flooding direct seeding technology does not need to make a box and ditches in the field, can greatly lighten the labor intensity, can effectively prevent and control bird damage and mouse damage by covering the paddy field with a water layer, can control weeds, reduces the loss of fertilizer, and is more suitable for mechanized production of paddy rice. However, the existing rice varieties for large-area production almost cannot sprout and grow normally under underwater hypoxia conditions, and it is difficult to sow full seedlings in one step. Therefore, aiming at the problem of full seedling of the flooded direct-seeding rice, providing a corresponding low-oxygen-resistant variety, or enhancing the low-oxygen-resistant capability of the flooded direct-seeding rice by a certain agronomic measure in the growth process of the flooded direct-seeding rice, and improving the seedling rate and the yield of the flooded direct-seeding rice is particularly important.
At present, although various reports about genes for regulating and controlling the hypoxia tolerance of rice or molecular markers related to hypoxia tolerance of rice exist, the related genes can be utilized for molecular breeding of hypoxia tolerant rice or the related molecular markers can be utilized for molecular marker assisted breeding of hypoxia tolerant rice. However, in view of the longer period of time and the higher difficulty of breeding, no related low-oxygen-tolerant rice variety exists at present. The method for enhancing the hypoxia tolerance of the flooded direct-seeding rice by a certain agronomic measure is probably a more direct and rapid method, but no report or commodity application of the seed soaking agent related to the hypoxia tolerance of the flooded direct-seeding rice exists at present. Therefore, it is necessary to provide a hypoxia-resistant seed soaking agent for water-flooded direct-seeding rice, and the seedling rate and yield of the water-flooded direct-seeding rice are improved.
