补充资料:甘蔗栽培制度(cropping system of sugarcane)
甘蔗栽培制度(cropping system of sugarcane) 蔗田轮作:水田蔗区甘蔗主要与水稻、小麦、油菜、蚕豆、蔬菜等作物轮作。实行稻蔗轮作,除具有水旱轮作一般优点外,水稻可利用剩余养料和蔗根等有机残余物,土壤也较疏松,利于增产;水稻收获后,留在田里的稻根和稻秆,可增加土壤有机质和钾的含量,对甘蔗生长也有利。旱地蔗区甘蔗多与甘薯、大豆、花生、蔬菜等作物轮作。轮作周期长短,根据当地甘蔗种植面积比例、土壤肥力、病虫情况、生产水平和经济条件而定,一般甘蔗种植2-3年,其他作物种植1-2年。 蔗田间作:甘蔗生长期长,行距大,封行迟,下种或移栽后至封行约有2-3个月,利用这段时间,在行间种植其他短期作物,可增加复种指数,提高光能利用率,增加农作物产量,又可提早覆盖地面,改善蔗田生态环境,减少水分蒸发,防止杂草滋生。间作作物多采用大豆、花生、绿豆、番茄、黄瓜等。 蔗田套种:在前作物收获前,把甘蔗套种在前作物行间,可充分利用土地,延长甘蔗生长期。中国蔗田套种的方式有:在小麦、油菜、蚕豆、豌豆、蔬菜等冬作物中套种春植蔗;在早稻、春花生中套种夏植蔗;在晚稻、甘薯、秋花中套种秋植蔗;在冬作物的蔬菜中套种冬植蔗。 种植方式:甘蔗有新植和宿根两种。 新植蔗:生产上利用蔗种种植的甘蔗种新植蔗。春植蔗是春季下种,生长期8月至12个月。当年冬季或翌年春季收获。中国主要蔗区处于亚热带和温带,普遍采用春植蔗。其发芽正值春季温度回升,生长盛期在6月至10月的强光、高温季节,有利于生长。成熟期又处在冷凉、干燥的冬季,有利于糖分积累。但下种季节有的蔗区遇低温阴雨,有的蔗区春旱,对发芽出苗不利。秋植蔗在8月至10月下种,翌年冬季收获。秋植蔗下种时温度高,发芽快,发芽率高,分蘖和伸长时间早又长,成熟也早,具有高产、高糖的优越性。但生长期长达一年半,土地利用率低,又是害虫越冬的场所,为害较严重。中国多数蔗区冬季有不同程度的霜冻,所以采用秋植的较少。冬植蔗在12月至翌年1月下种,适合冬季没有严重霜冻的蔗区采用。冬植蔗可利用冬季土温比气温高和根点可在10℃以上萌发的特性,先长根,为翌年早生快发创造条件,又可减少蔗种贮藏。但在低温、干旱季节下种,发芽时间长,出土慢,发芽率高,分蘖多,但发芽期和苗期占用生长条件最好的时期,有效伸长期短,生长不足,产量低,压榨时蔗茎成熟度差,蔗糖分较低;主要用于做种,下部可供榨糖;采用极早熟品种和育苗移栽技术,蔗和糖的产量可明显增长。 蔗田培养食用菌:甘蔗生长中后期,蔗田小气候适于多种食用菌生长。利用蔗茎为柱搭架,以蔗叶为天然遮荫物,在叶层下部和架的四周用塑料薄膜围盖,成为一座临时的田间培养室。架上铺放培养料为菇床,栽培蘑菇、猴头菇和香菇等食用菌。食用菌的培养料主要来自甘蔗的副产物。 |
