1977年,我们去湖北省黄岗县参观学习无土育苗经验,回来后立即组织8个水田重点队(场)开展试验,由9月20日～10月底搞了两期无土育秧试验,初步体会如下: 1.抓好播种关①精选种子:种子质量一定要好,发芽率要求在95％以上,不足90％的不能做种。做好盐水选种和药剂消毒。②恒温浸种,高温催芽,催小芽:浸种时间以3天为宜,水温30℃左右,每天早上换一次清水(水温30
In 1977, we went to Huanggang County, Hubei Province to visit and learn soilless seedling experience. After returning, we organized 8 paddy field key teams (field) to carry out the experiment. From September 20 to the end of October, we conducted two soilless seedling tests, initially realizing As follows: 1. Do a good job sowing ① Selective seed: seed quality must be good, the germination rate of more than 95%, less than 90% of species can not do. Good salt selection and disinfectant. ② soaking temperature, high temperature germination, urinary small buds: soaking time to 3 days is appropriate, the water temperature about 30 ℃, change the water every morning (water temperature 30
