早春地膜栽培蔬菜具有早熟、早上市、高产优质的特点。但地膜栽培也容易形成杂草滋生,在作物生长中后期杂草把地膜抬起。据调查,草害严重的能将地膜抬离地面16厘米,影响通风透光,降低结实率和产量,其中又以对矮秆作物如菜椒等影响为甚。为消灭地膜内的杂草,我们于1983～1984年进行了用不同除草剂对不同菜田除草试验。 供试药剂及每亩用量为:①48％氟氯灵3两;②50％杀草丹5两;③60％丁草安2两;④48％拉索2两;96％禾大壮2两;⑤25％除草醚1斤。以上均加水120斤喷雾。
Early spring film cultivation of vegetables with precocious, morning market, high yield and quality characteristics. But mulching is also easy to form weeds breeding grass in the late crop growth weeds raised. According to the survey, serious damage to the grass can lift the ground film 16 cm, affecting the ventilation and light, reducing the seed setting rate and yield, which in turn on the dwarf crops such as pepper even worse. In order to eliminate the weeds in the mulching film, we conducted the weeding experiments with different herbicides on different vegetable fields from 1983 to 1984. Test agents and the amount of acreage per acre: ① 48% chlorothalon 3 two; ② 50% to kill Cadesin 5 two; ③ 60% Dingcao An 2 two; ④ 48% cable 2 two; 96% Wo big strong 2 two; ⑤ 25% Weeding ether 1 kg. More than 120 pounds of water spray.
