猪殃殃(Galiumspruiuml),俗名“涩拉秧”,属茜草科,是我省麦地的恶性杂草.全省常年发生约三千万亩,一般地块每平方米60—80株,严重地块达150株以上。猪殃殃出土比小麦晚7—10天,出苗后10—15天出现分枝。越冬期簇生或匍伏地面,春季长势加快,沿麦株上攀并覆盖小麦,使小麦减产15—30％。用人工防除,费工多,易踩断小麦,效果不好。为此,1980—1986年对其进行了化学防除技术研究和试验示范,
Galium spruce (Galiumspruiuml), commonly known as “Asparagus seedling”, is a Rubiaceae, is a malignant weed in the wheat field.The province perennial about 30 million mu, the general block 60-80 per square meter, serious Land of 150 or more. Pig apologists unearthed 7-10 days later than wheat, emergence of branches 10-15 days after emergence. Overwintering tufted or creeping on the ground, the spring is accelerating, climbed and covered wheat along the wheat plants, the wheat yield 15-30%. With artificial control, more labor, easy to step off the wheat, the effect is not good. To this end, from 1980 to 1986 on its chemical control technology research and experimental demonstration,
