Problems solved by technology

In order to ensure the shelf life of rice seeds, it is often necessary to dry the fresh seeds. With the reduction of moisture, the shelf life is extended, but the effects of soaking and accelerating germination in different seed states are very different. During the process, unbalanced germination phenomenon is common, especially for soaking and accelerating germination of ultra-dry rice seeds with moisture content ≤ 8%, it is easy to cause nutrient dissolution loss in rice seeds, low seed germination rate, poor germination potential and uniformity, and it is difficult to To achieve the desired effect of "fast, uniform, uniform and strong", resulting in nutritional deficiency or imbalance in the rice seedling stage, slow growth rate after transplanting, incomplete development in the later stage, and reduced rice yield

Abstract

The invention provides an efficient germination accelerating and rapid seedling raising method for rice seeds. The method includes the steps that (1) the ultra-dry rice seeds with the water content smaller than or equal to 8% are subjected to seed hardening in a high-temperature wet environment; (2) the seeds are dried in the sun and ventilating is conducted; (3) the rice seeds are soaked in seedsoaking solution containing 0.1-0.5% of sargassum pallidum extracting solution at the temperature of 30-32 DEG C, draining is conducted, and then the rice seeds are soaked in seed soaking solution containing 0.8-1.0% of the sargassum pallidum extracting solution at the temperature of 35-36 DEG C; and (4) the seeds are cleaned, drained, and spread in a steam greenhouse for accelerating germination,mixed aqueous solution containing L-malic acid and fumaric acid is regularly and uniformly sprayed on surfaces, cooling is conducted to 28-30 DEG C after the rice seeds are germinated, and continuously accelerating germination is conducted. According to the efficient germination accelerating and rapid seedling raising method for the rice seeds, high-temperature wet refining is adopted, the seedsare soaked in the seed soaking solution of the sargassum pallidum extracting solutions with different concentrations and combined with the steam greenhouse, and the method is more suitable for efficient germination accelerating of low-moisture rice seeds, so that the seed germination effect is improved, and the rice seedling raising quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for efficiently accelerating germination and rapidly growing seedlings of rice seeds. Background technique [0002] As a major food crop, rice plays an important role in global food security. The germination technology of rice seeds is a key link in the rice production process and the basis for cultivating strong seedlings. High-quality rice seedlings are the guarantee of high yield and high quality of rice. In order to ensure the shelf life of rice seeds, it is often necessary to dry the fresh seeds. With the reduction of moisture, the shelf life is extended, but the effects of soaking and accelerating germination in different seed states are very different. During the process, unbalanced germination phenomenon is common, especially for soaking and accelerating germination of ultra-dry rice seeds with moisture content ≤ 8%, it is easy to cause nutrient dissolutio...
