The pros and cons of seeds are directly related to the peasants' one-year harvest. Blind introduction of rice seeds will inevitably bring major losses to large grain producers. Therefore, when introducing new varieties of rice this year, I suggest farmers throughout the country have a correct grasp of the “five characteristicsâ€: One should pay attention to "adaptability". The comprehensive coordination of natural, cultivated, tillage and management conditions for new varieties of early rice, middle rice, one night and two nights is suitable for local planting. Second, we must pay attention to "warmness." Taking the Jiujiang region of Jiangxi Province as an example, some new rice varieties are sensitive to temperature when planted in Jiujiang. The early rice varieties with a warm temperature must reach a certain accumulated temperature to differentiate into panicles, otherwise they cannot form young panicles. For example, in the Jiujiang region of Jiangxi Province, the conventional rice variety has a short growing period of high temperature during the production process; otherwise, it has a long growing period. Third, pay attention to "photosensitivity." Some late rice varieties are sensitive to light. The young spikes must be formed in a short environment at night, otherwise the new varieties of “photosensitive†late rice have only long stems and leaves without spikes. Fourth, pay attention to "speciality." In addition to the commonness of rice crops, all varieties have their own particularities. Such as adaptability, different cultivation methods. If any breed is insensitive to temperature and daily photography, it will take a long time to start young panicle differentiation. Fifth, pay attention to "regionality." When rice seeds are introduced every year by local rice breeding companies (agrotechnical stations), the first consideration is to introduce the ecological conditions of early rice, mid-season, one-night and two-night varieties, the ecological conditions of the introduced regions, and the introduction of regional ecological conditions. Differences in size, latitude, and proximity to different altitudes are easy to introduce. All localities must implement a strict quarantine system and do not introduce rice seeds from quarantine pests and diseases in the outer areas to the counties, cities, townships, and villages. The introduced rice seeds must also be planted first. After trials, they showed that their adaptability, high yield, resistance to disease and fertilizer, and high yield can be promoted in large areas in Daejeon.
