摘要
为提高土地利用率、增加甘蔗种植综合经济效益,进行粉垄耕作下甘蔗宽窄行间作花生试验,探索粉垄宽窄行间作对甘蔗农艺性状、光合生理特性、产量品质及经济效益的影响。结果表明,与常规单作相比,粉垄宽窄行间作的甘蔗分蘖率、株高、有效茎数、产量和含糖量有所下降,蔗糖分和纤维分有所提高,对出苗率、茎径和蔗汁重力纯度影响规律不明显;甘蔗分蘖期的净光合速率、气孔导度和蒸腾速率有所提高,对胞间二氧化碳浓度和叶片SPAD值影响规律不明显;伸长期的气孔导度、蒸腾速率和叶片SPAD值有所提高,对净光合速率和胞间二氧化碳浓度影响规律不明显;成熟期的净光合速率、气孔导度、胞间二氧化碳浓度和蒸腾速率有所提高,对叶片SPAD值影响规律不明显。因多收1造花生,‘桂糖44号’甘蔗每667m2总收益提高561~749元,纯收益提高265~414元;‘桂糖55号’甘蔗每667m2总收益提高284~467元,纯收益提高96~188元。‘桂糖55号’甘蔗3.0m宽窄行粉垄间作模式的总收益和纯收益最高,‘桂糖44号’甘蔗3.0m宽窄行粉垄间作模式次之。
In order to improve the land utilization rate and increase the comprehensive economic benefits of sugarcane planting the experiment of intercropping peanut between wide and narrow rows of sugarcane under Fenlong tillage was carried out to explore the effects on the agronomic characteristics,photosynthetic physiological characteristics,yield,quality and economic benefits of sugarcane.The results showed that,compared with conventional single cropping,the tillering rate,plant height,effective stem number,yield and sugar content of sugarcane were decreased,the sucrose content and fiber content were increased,and the effects on seedling rate,stem diameter and gravity purity of sugarcane juice were not obvious.The net photosynthetic rate,stomatal conductance and transpiration rate on sugarcane were increased at tillering stage,but the effects on intercellular carbon dioxide concentration and SPAD value were not obvious.The stomatal conductance,transpiration rate and SPAD value were increased in extension period,but the effects on net photosynthetic rate and intercellular carbon dioxide concentration were not obvious.The net photosynthetic rate,stomatal conductance,intercellular carbon dioxide concentration and transpiration rate were increased during the mature stage,but the effect on SPAD value was not obvious.Due to an extra crop of peanuts,the total income of'Guitang 44'sugarcane increased by 561 to 749 yuan per 667 m2,and the net income increased by 265 to 414 yuan;the total income of'Guitang 55'sugarcane increased by 284 to 467 yuan per 667 m2,and the net income increased by 96 to 188 yuan.The total income and net income of'Guitang 55'sugarcane in 3.0 m wide-narrow row intercropping pattern were the highest,followed by'Guitang 44'sugarcane in 3.0 m wide-narrow row intercropping pattern.
