水稻是我国栽培面积最大、总产最多的主要粮食作物。目前,我国水稻播种面积为3200万公顷,占全国粮食播种面积的27%;稻谷总产量约为20亿吨,占粮食总产的39%;从事稻作生产的农户约占农户总数的50%;全国约有60%以上的人口以稻米为主食。因此,水稻的丰产丰收对于我国粮食安全至关重要。然而我国水稻自播种、秧苗期至成熟期均遭受到不同种类害虫的危害。从第16期开始,本刊以连载的方式来介绍水稻害虫的识别与防治技术。
Rice is China’s largest cultivated area, the largest total output of the main food crops. At present, the sown area of rice in our country is 32 million hectares, accounting for 27% of the sown area of grain in the country. The total output of paddy is about 2 billion tons, accounting for 39% of the total grain output. The number of farmers engaged in rice production accounts for about 50% About 60% of the population in the country is mainly rice. Therefore, the bumper harvest of rice is of crucial importance to our food security. However, rice from the seeding, seedling to maturity are subject to different types of pests. Starting from the 16th issue, this journal introduces the identification and prevention and control of rice pests in a serial manner.
