在当地套作模式基础上,兼顾小麦、小辣椒双高产,通过行距调整、株距配置、品种筛选、合理密植、共生期和中后期管理等措施,改善田间群体结构,增加小麦、小辣椒种植密度,发挥小麦边行优势,提高对小辣椒的遮阴效果,降低病虫为害,实现小麦、小辣椒产量和品质的双提升。配置由1 m一带改为0.8 m一带,缩小小辣椒行距,由40 cm缩减到20 cm,每亩小麦群体增加2.5万~3.0万头,小辣椒群体增加2 000~2 500株;小麦、小辣椒每亩平均单产均达到500 kg。每亩效益5 000~6 000元,亩增效益1 000元左右。
On the basis of local intercropping mode, taking both the high yield of wheat and peppers into account, we improved the population structure of the field and increased the planting density of wheat and peppers through the measures of row spacing adjustment, spacing, variety screening, rational close planting, symbiotic period and mid- and late-stage management , Play wheat edge line advantage, improve the shade of peppers, reduce pests and diseases, to achieve wheat, peppers yield and quality of the double upgrade. The configuration was changed from 1 m to 0.8 m. The pepper spacing was reduced from 40 cm to 20 cm, with an increase of 25,000 to 30,000 heads per mu of wheat and an increase of 2,500 to 2,500 peppers. Wheat and small Pepper average yield per acre reached 500 kg. The benefit per mu ranges from 5,000 yuan to 6,000 yuan, and the profit per mu increases by 1,000 yuan.
