烤田是水稻栽培的基本措施之一,不但促使稻根深扎、控制无效分蘖、保障生长整齐、不倒伏、成穗率高、子粒饱满,又能减轻三化螟的侵害。近年来我们对烤田与三化螟害的关系进行了调查,所得结果报告于下。 1.减少成虫产卵量 在合肥地区主要世代(第三代)的成虫发生期,烤田的每亩卵块累计数为1,660块,不烤田的高达26,780块。烤田的减少成虫产卵量15倍多。
Baked field is one of the basic measures of rice cultivation, not only to promote deep-rooted rice tie, control of ineffective tillers, protect the growth and tidy, non-lodging, spike rate, full grain, but also reduce the yellow rice borer invasion. In recent years, we conducted a survey on the relationship between the bakeries and the damage of the yellow rice borer. The results are reported below. 1. Reduce adult fecundity In the main generation (third generation) of Hefei adults occur, the cumulative number of oiled eggs per mu of grilled fields was 1,660, up to 26,780 not baked fields. Grilled fields to reduce the amount of eggs laid by adults more than 15 times.
