广东是我国主要粮产区之一,水稻双造连作,气候上早春2—3月回暖,早稻播种较早。但早春天气冷暖不定,有阵寒,有低温阴雨,以致各地有不同程度烂秧、死苗,影响早稻生产,甚至延误全年生产季节,对生产威胁很大。 Guangdong is one of China’s major grain-producing areas. The double-cropping of rice continues to pick up in the early spring in February-March and early sowing in early rice. However, in the early spring, the weather is warm and cold, with cold and rainy days, causing low temperature and rainy weather, causing various degrees of rotting seedlings and dead seedlings throughout the country, affecting the production of early rice and even delaying the annual production season, threatening the production.
