Comparative Analysis of Benefits of Zhangshugang Pepper and Grain Crop Rotation
A large-scale experiment was conducted to analyze the benefits of Zhangshugang Pepper,fresh corn,grain-fed corn,soybean,and rice rotation in greenhouses and open fields,as well as upland rice rotation in greenhouses.The results show that pepper cultivated in greenhouses and open fields can rotate with the experimental grain crops in the same year,and its annual benefit increase ratio is 14-33 times higher than double cropping rice.The benefits of the same grain crop and pepper rotation in greenhouses are higher than those in open fields by more than 10 000 yuan,and the difference in benefits is mainly caused by pepper cultivation in greenhouses.Among the five crop rotations,fresh corn Jintianshun 999 cultivated in greenhouses and open fields has the best benefits of 351 105 yuan/hm2 and 197 505 yuan/hm2,respectively.The benefit increase ratio is 5.6%and 6.3%lower than that of single pepper cultivation in greenhouses and open fields,and the benefit increase ratio decreases the least.To improve soil and facilitate the subsequent production of pepper,the rotation of pepper and rice(transplanting)is the optimal choice.
