油菜不同地表覆盖栽培方式产量与效益的比较研究

Comparative study on yield and economic benefits of rape under different planting and mulching patterns

  • 摘要: 西部地区是我国油菜的主产区, 干旱是该地区油菜高产的主要制约因子。为寻求适宜西北沿山干旱区自然气候条件下油菜抗旱栽培技术, 选膜侧沟播、半膜覆盖平播、全膜覆盖平播、麦秸覆盖平播和全膜覆盖沟播5种地表覆盖栽培方式, 与常规露地平播种植方法进行了植株形态、产量和效益比较。结果表明: 不同地表覆盖栽培方式对油菜株高、茎粗、主花序长度、单株分枝数量、角果数等性状产生较大影响。除麦秸覆盖平播外, 全膜覆盖平播、全膜覆盖沟播、膜侧沟播和半膜覆盖平播均能显著提高油菜的株高、茎粗和主花序长度; 全膜覆盖平播和全膜覆盖沟播可有效地促进油菜植株的一次分枝, 而半膜覆盖平播、膜侧沟播和麦秸覆盖平播无明显作用; 地表覆盖处理抑制了油菜的二次分枝。全膜覆盖沟播、全膜覆盖平播、膜侧沟播和半膜覆盖平播均促进了油菜单株角果数的增多, 而膜侧沟播、麦草覆盖平播、半膜覆盖平播提高了油菜角粒数, 全膜覆盖沟播、全膜覆盖平播、膜侧沟播、麦秸覆盖平播降低了油菜千粒重。采用全膜覆盖沟播、全膜覆盖平播、膜侧沟播栽培油菜, 产量分别达2 111.25 kg·hm-2、2 017.95 kg·hm-2和1 934.70 kg·hm-2, 比常规露地平播增产52.16 %、45.44 %和39.44 %; 纯经济效益分别达1 985.85元·hm-2、1 868.55元·hm-2和1 495.20元·hm-2, 比常规露地平播高2.22倍、2.03倍和1.43倍。半膜覆盖平播、麦秸覆盖平播产量及效益均显著低于常规露地平播。因此, 我国西北沿山旱作区采用全膜覆盖沟播、全膜覆盖平播、膜侧沟播等3种栽培方式种植油菜, 可获得较高的产量和较为理想的经济收入, 应在生产上大力推广应用。

     

    Abstract: To establish drought-resistant cultivation techniques of rape (Brassica napus) in dry mountainous lands of the West China, the characteristics, yield and economic benefits of rape under five mulching/planting treatments were investigated in an field experiment using conventional cultivation as the control. The treatments included furrow planting with plastic-film-covered ridges (FURP), flat planting with half plastic-film mulch (FLHP), flat planting with complete plastic-film mulch (FLOP), flat planting with wheat-straw mulch (FLW) and furrow planting with plastic-film-covered furrows/ridges (FUFRP). Result showed that FLOP, FUFRP, FURP and FLHP significantly increased rape plant height, stem diameter and length of main inflorescence. While FLOP and FUFRP promoted first branching of rape, FLHP, FURP and FLW inhibited it. The five mulching/planting treatments unduly affected secondary branching of rape. Whereas FUFRP, FLOP, FURP and FLHP increased pod number per plant; FURP, FLW and FLHP increased grain number per pod. There were notable negative effects of FUFRP, FLOP, FURP and FLW on the 1000-grain weight of rape. Actual yields of FUFRP, FLOP and FURP were 2 111.25 kg·hm-2, 2 017.95 kg·hm-2 and 1 934.70 kg·hm-2, respectively representing an increase of 52.16%, 45.44% and 39.44% over conventional cultivation. Net economic benefits of FUFRP, FLOP and FURP were 1 985.85 Yuan·hm-2、1 868.55 Yuan·hm-2 and 1 495.20 Yuan·hm-2 which were respectively 2.22, 2.03 and 1.43 times higher than those of conventional cultivation. Yields and economic benefits of FLHP and FLW were significantly lower than those of conventional cultivation. The study suggested that in dry mountainous lands of the West China, FUFRP, FLOP and FURP were suitable mulching and planting patterns for rape cultivation. In terms of yield and economic benefits, the outputs of these cultivation patterns were higher than those of the other patterns of cultivation.
