绿豆生育期短,适播期长,4月下旬～7月中旬均可播种。早熟品种在冀中南地区可一年两熟。春、夏播绿豆生长期间的气候生态环境迥然不同,导致病虫害的种群有很大差异,需采取相应措施综合防治。我们于1987～1989年,对冀南地区绿豆病虫的主要种类、发生为害规律及防治措施进行了研究,通过积极综合防治,绿豆亩增产30～80%。现将其防治方法介绍如下:
Mung bean growth period is short, suitable sowing period, late April ~ mid July can be sown. Early maturing varieties in southern Hebei can be twice a year. Spring and summer sowing mung bean climate during the growth of very different ecological environment, resulting in pests and diseases are very different populations need to take appropriate measures to comprehensive prevention and control. From 1987 to 1989, we studied the main types of mungbean pests and diseases and their control measures in the area of southern Hebei. Through active and comprehensive prevention and control, mung bean mu increased by 30-80%. Now the prevention and treatment methods are described below:
