上海国营农场和郊县,水稻种植面积占秋熟作物的70～92％,其中,大部分为单季晚粳和中粳品种,少部分为中籼、特种稻和后季稻。由于农场、乡村劳动力正向乡镇企业和第三产业等领域转移,高效、节能、省工的水直播稻技术,受到了人们的普遍欢迎。然而,水直播稻田害虫的发生,与移栽稻不尽相同,为此,作者根据3年来的调查试验,对直播稻害虫的发生及其防治,进行了较系统的总结。
In Shanghai state-run farms and suburban counties, the rice planting area accounts for 70-92% of the autumn ripe crops, most of which are single-season late japonica and middle-season japonica varieties, with a small proportion of medium-season indica, special and later-season rice. Due to the transfer of farms and rural labor to the township and village enterprises and the tertiary industry, high-efficiency, energy-saving and labor-saving techniques for direct seeding rice have been widely welcomed by people. However, the occurrence of direct seeding rice fields pests is different from that of transplanting rice. Therefore, based on the investigation of three years, the author summarizes the occurrence and control of direct seeding rice pests.
