1986~2000年由科研、推广及管理8家单位组成的浙江省农田杂草研究协作组在浙江省嘉兴、杭州、金华和温州4个农区,对水稻田杂草发生种类和危害程度开展全面系统调查,涉及早稻、晚稻、单季稻、秧田等各种耕作稻制和直播、抛秧、旱育秧等不同轻型栽培方式。调查结果,浙江省水稻田共有杂草41科77属131种和2变种,其中主要杂草21科35属41种和1变种,如稗草、千金子、双穗雀稗、异型莎草、空心莲子草、鸭舌草、矮慈菇、节节菜、牛毛毡、丁香蓼等。杂草危害以单季稻田最重,晚稻田次之,早稻田最轻;早稻田杂草群落简单,以稗草占绝对优势,而晚稻田群落较为复杂,由稗草和阔叶草及莎草共同构成群落。一些杂草在局部地区造成严重危害。同时,直播田和抛秧田杂草危害重于常规移栽田,早育秧田杂草种类多于常规水育秧田。长期使用除草剂,使常规栽培稻田一年生杂草发生减轻,而多年生杂草危害上升,但稗草仍为主要恶性杂草。最后,附有浙江省水稻田杂草名录。
1986~2000年由科研、推廣及管理8傢單位組成的浙江省農田雜草研究協作組在浙江省嘉興、杭州、金華和溫州4箇農區,對水稻田雜草髮生種類和危害程度開展全麵繫統調查,涉及早稻、晚稻、單季稻、秧田等各種耕作稻製和直播、拋秧、旱育秧等不同輕型栽培方式。調查結果,浙江省水稻田共有雜草41科77屬131種和2變種,其中主要雜草21科35屬41種和1變種,如稗草、韆金子、雙穗雀稗、異型莎草、空心蓮子草、鴨舌草、矮慈菇、節節菜、牛毛氈、丁香蓼等。雜草危害以單季稻田最重,晚稻田次之,早稻田最輕;早稻田雜草群落簡單,以稗草佔絕對優勢,而晚稻田群落較為複雜,由稗草和闊葉草及莎草共同構成群落。一些雜草在跼部地區造成嚴重危害。同時,直播田和拋秧田雜草危害重于常規移栽田,早育秧田雜草種類多于常規水育秧田。長期使用除草劑,使常規栽培稻田一年生雜草髮生減輕,而多年生雜草危害上升,但稗草仍為主要噁性雜草。最後,附有浙江省水稻田雜草名錄。

Surveys were made for weed species and their damages in rice fields in Jiaxing, Hangzhou, Jinhua, and Wenzhou, Zhejiang Province in 1986- 2000 by a collaborative team of scientists. It involved early rice, late rice, one season rice, rice nursery or direct seeding rice, transplanted rice by seedling-broadcasting, arid rice nursery. The result showed that there are 131 species and 2 varieties belonging to 77 genus and 41 families of weeds appearing in rice fields in Zhejiang, among which 41 species and 1 variety belonging to 35 genus and 21 families are dominant. They are Echinochloa crusgalli, Leptochloa chinensis, Paspalum distichum, Cyperus difformis, Alternanthera philoxeroides, Monochoria vaginalis, Sagittaria sagittifolia, Rotala indica, Eleocharis yokoscensis, Ludwigia prostrata, et al. Weeds have the heaviest damage to one season rice, heavier to late rice, and the least to early rice. In simple weed community in early rice fields, E. crusgalliis only one main weed, whereas weed community in late rice fields is complex and consists of E. crusgalli, broad leaf weeds and sedge weeds. The damage of weeds is heavier in fields of direct seeding rice and transplanted rice by seedling-broadcastng than in conventional cultivation fields, and there are more weed species in arid rice nursery than in paddy rice nursery. Since long application of herbicides, annual weeds have decreased, perennial weeds increased, while E. crusgalli keeps its main place in rice fields. A list of weed species in rice fields was appended at the end.
