Embodiment 1
[0021] The method for growing rice seedlings in a cold area in which soaked seeds and a composite matrix are integrally formed comprises the following steps:
[0022] The first step is seed soaking treatment, including rice seed selection and soaking liquid soaking, using a rice seed selection machine to separate the seeds of grains, aphids, moth-eaten, mildew, smut and smaller weed seeds, Sand, clods are removed, and then the selected seeds are soaked for 24 hours and then air-dried naturally. The amount of the soaking solution is based on the complete submersion of the seeds at the liquid level; the soaking solution can significantly improve the low temperature and disease resistance of rice seeds and To promote root development, the soaking solution is a mixed solution of melatonin and 30% chlormequat-uniconazole microemulsion, and the mass concentration of melatonin is 10 μmol L -1 , the concentration of the 30% chlormequat·uniconazole microemulsion is 6g·L -1 .

[0037] The method for growing rice seedlings in a cold area in which soaked seeds and a composite matrix are integrally formed comprises the following steps:
[0038] The first step is seed soaking treatment, including rice seed selection and soaking liquid soaking, using a rice seed selection machine to separate the seeds of grains, aphids, moth-eaten, mildew, smut and smaller weed seeds, Sand, clods are removed, and then the selected seeds are soaked for 24 hours and then air-dried naturally. The amount of the soaking solution is based on the complete submersion of the seeds at the liquid level; the soaking solution can significantly improve the low temperature and disease resistance of rice seeds and To promote root development, the soaking solution is a mixed solution of melatonin and 30% chlormequat uniconazole microemulsion, and the mass concentration of melatonin is 15 μmol L -1 , the concentration of 30% chlormequat · uniconazole microemulsion is 9g · L -1 .
