省稻螟电子计算机测报协作组于四月下旬对赣北、赣中、赣南部份有代表性稻区二、三化螟发生期和发生量作出中长期预报(表1、2)。根据预报,上述稻区今年二化螟发生期为中发或中发偏晚;发生量属中发年份。三化螟发生期,赣中北稻区属中发偏晚,发生量属轻发年份;赣南稻区,发生期属中发,发生量为轻发或中发偏轻。根据预报预测,各地对二化螟仍应注意防治,对三化螟则可基本不防,但对早稻迟熟品种面积积大或耕作制度复杂的局部
In late April, the collaborating group of rice-stem borers and their computers reported long-term and medium-term forecasts on the occurrence and occurrence of the second and third rice borers in representative rice areas in northern Jiangxi, central Jiangxi and southern Jiangxi (Table 1 and Table 2). According to the forecast, the occurrence of the above rice stem borers in this year is either middle or late; the occurrence is in the middle of the year. Occurrence of stem borer, Jiangxi Province in the northern part of the rice is late, the amount of light-fat years; southern Jiangxi Province, the occurrence period is in the hair, the occurrence of light hair or hair too light. According to forecast and forecasting, all places should still pay attention to the prevention and control of the rice stem borer, but not to the rice stem borer, but the part of the late rice crop area or the tillage system is complicated
