摘要
The growth speed,fresh grass yield,nutritional components,soil nutrient variation and economic benefit of Brassica napobrassica cv. Huaxi under different planting patterns( drilling,hole sowing and seedling transplanting) were analyzed by a test of interplanting B. napobrassica cv. Huaxi under economic fruit forest,to solve the contradiction between food and feed during rapid development of ecological animal husbandry and improve land utilization rate. The comprehensive performance of B. napobrassica cv. Huaxi was good under the three planting patterns,and the comprehensive performance of B. napobrassica cv. Huaxi under the seedling transplanting pattern was the best among the three planting patterns. The fresh grass yield and net profit of B. napobrassica cv. Huaxi under the seedling transplanting pattern can reach 125 580. 0 kg/hm^2 and 16 674. 0 Yuan/hm^2,respectively. Interplanting B. napobrassica cv. Huaxi under economic fruit forest can improve soil physical and chemical properties,increase soil nutrients and inhibit weed growth.
