在坡耕地白浆土上开展白地膜种植玉米、黑地膜种植玉米、祼地种植玉米的比较试验,调查分析各处理的生育期、叶片生长速度、生物学性状、产量及产值。结果表明,白地膜种植玉米较黑地膜种植玉米、祼地种植玉米分别增产118.5、2 712.0 kg/hm~2,分别增值151.68、1 554.12元/hm~2,白地膜种植玉米、黑地膜种植玉米均较祼地种植玉米生育期提前6 d,白地膜种植玉米较黑地膜种植玉米、祼地种植玉米收获穗分别多360、885穗/hm~2。表明白地膜种植玉米对提高保苗率、促进各生育期提前作用显著,在桦甸坡耕地应用白地膜种植玉米是玉米高产稳产优质的根本保障。
In the sloping arable land of white soil to carry out the white film planting corn, black film cultivation of corn, to cultivate corn marsh comparative test to investigate the treatment of growth period, leaf growth rate, biological characteristics, yield and output value. The results showed that the planting density of white maize was increased by 118.5,2 712.0 kg / hm ~ 2 compared with black maize and marshland, respectively, with added value of 151.68 Yuan and 554.12 Yuan / ha, respectively. Compared with the control, the growing period of maize was 6 days earlier than that of maize, while that of maize growing in white maize was 360.885 spikes / hm ~ 2 more than that of maize planting in maize. The results showed that planting maize with white film can improve the seedling-raising rate and promote the early effect of each growth period. The application of white film-growing maize in cultivated land of Huadian meadow is the fundamental guarantee of high and stable yield and quality of maize.
