甘蔗是我场主要作物之一,历年甘蔗种植面积在二万五千亩左右,甘蔗生育期长,在甘蔗出苗前或刚出苗时,正是各类杂草萌发的盛期。农场地多劳力少,人工除草较困难,也费工费时,往往影响甘蔗的产量,一般可使甘蔗减产20—50％。为此,我们进行了多年的杂草种类及其生长规律的调查观察,在此同时并进行了甘蔗地化学除草的试验研究,对我场甘蔗地草害的化学防除作了一些探索。一、甘蔗地主要杂草的种类: 我场甘蔗前作棉花,冬耕休闲。主要杂草种类有14科34种:禾本科有双穗雀稗、马唐、
Sugarcane is one of the main crops in our field. The annual area of sugarcane planting is about 25,000 mu. The growth period of sugar cane is long. Before the emergence of sugarcane or when it is emerging, it is the peak of all kinds of weeds germination. Farm labor and less labor, artificial weeding more difficult, but also laborious and time-consuming, often affect the yield of sugarcane, sugar cane can generally cut 20-50%. To this end, we conducted many years of weed species and its growth law of the survey observed at the same time and conducted a chemical weed control study of sugarcane field, the field of sugarcane grass weeds chemical control made some exploration. First, the main weed species of sugar cane: my field of cotton before sugar cane, winter plowing leisure. There are 14 families and 34 main types of weeds: gramineous paspalum, crabgrass,
