1.甘蓝蚜是新疆维吾尔自治区为害十字花科作物,特别是晚甘蓝最严重的害虫。不同年份因被害不能包心因而減产达22—54％。 2.1963—65年来研究表明,在甘蓝蚜大发生之年,在晚甘蓝定植时穴施,或在定植后每株侧施4％有效成份的乙拌磷颗粒剂5克一次;或在一般发生年份,每株穴施或侧施2％有效成份乙拌磷颗粒剂3—5克一次,可以保证包心,获得丰产.即使在大发生之年,定植时每株穴施2％者2.5克,此后再侧施一次,亦可保证丰产。侧施时间以在晚甘蓝莲座期进行表现最好. 3.试验证明用乙拌磷颗粒剂作地下处理一次,其防治效果较一般地面喷药防治数次为佳。 4.甘蓝蚜越冬卵主要依附在晚甘蓝种株上,故晚甘蓝种株是每年的主要蚜源.春季移栽种株后,每株侧施5％有效成份乙拌磷颗粒剂5克,防治效果突出,种籽千粒重增加1.7倍。
1. Cabbage aphid is a cruciferous crop harmed in Xinjiang Uygur Autonomous Region, especially the most serious pest of late cabbage. In different years due to the victims can not be cautious and therefore cut production of 22-54%. Studies from 1963 to 65 years showed that in the year of large-scale occurrence of cabbage aphid, 5 grams of brimstone granules with 4% active ingredient per plant were applied once at the time of colonization of late cabbage or 5 grams once in normal occurrence year , Each hole facilities or lateral application of 2% active ingredient B clastosone granules 3-5 grams once, can guarantee the heart, access to high yield. Even in the great year, when planting 2% of each plant 2 grams 2.5 grams, Since then the facilities once again, but also to ensure high yield. Side application time to perform best in late brassy milky rosette stage.3 tests proved that the use of brife phosphorus granules for underground treatment, the prevention and treatment effect than the average ground spray prevention and treatment is better. Cabbage aphids overwintering eggs mainly depend on the cabbage varieties, so cabbage varieties are the main annual aphid source.After the spring transplanting strains, each side of 5% of the effective components of bixin phosphorus granules 5 grams, Control effect is outstanding, seed thousand grain weight increase 1.7 times.
