Abstract:

In order to improve the planting efficiency and explore the ecological planting pattern of honeysuckle flower in Gansu Province, we intercropped different cash crops in the early growth stage of honeysuckle, which were honeysuckle+ spring onion (T₁), honeysuckle+ cauliflower (T₂), honeysuckle+ soybean (T₃), honeysuckle+ ‘Shanghaiqing’(T₄), honeysuckle+ potato (T₅) and honeysuckle+ non-intercropping (T₆). By measuring the growth and development index of honeysuckle, soil water and heat, and the yield of honeysuckle and intercropping crops, we analyzed and compared the effects of ecological planting patterns on yield and economic benefit of honeysuckle in Gansu Province. The results showed that the survival rate of ‘Beihua 1’ in Gansu Province was higher, the average was over 94.44%, and the number of new shoot was between 7.81 and 9.19 in the same year, the length of new shoot was 3.39-5.83 cm, which grew well; the benefit of honeysuckle was low in the early stage of planting, with no yield in the same year. The average yield was 0.81 kg/10.8 m² in the second year, and the average total output value was 16.21 yuan/10.8 m². After interplanting, the yield of honeysuckle was increased significantly under T₃ treatment, the yield was1.45 kg/10.8 m², which was 158.93% higher than that of non interplanting; the economic benefit of T₄ treatment was the best, the total yield of interplanting crops was 38.36 kg/10.8 m², the economic benefits was 153.44 yuan/10.8 m². Therefore, intercropping different cash crop in early stage of honeysuckle can significantly improve its economic benefits and land use efficiency. Honeysuckle+ ‘Shanghaiqing’ is a suitable ecological planting method for honeysuckle cultivation in Gansu Province.
