Planting Adaptability of Brassica napobrassica cv. Huaxi Under Economic Fruit Forest

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.

经果林下花溪芜菁甘蓝的种植适应性

为解决生态畜牧业快速发展中人畜争粮争地的矛盾及提高土地利用率,开展经果林下套种花溪芜菁甘蓝试验,观测不同种植方式(条播、穴播及育苗移栽)芜菁甘蓝的生长速度和鲜草产量,分析芜菁甘蓝营养成分、土壤养分变化与套种模式的经济效益。结果表明,经果林内3种方式套种花溪芜菁甘蓝均有较好表现,以育苗移栽种植方式的鲜草产量最高,达125 580.0kg/hm^2;经济效益最好,纯利润达16 674.0元/hm^2。花溪芜菁甘蓝能适应林下土壤及生态条件,改善林下土壤理化性状,提高土壤养分,并能抑制果园杂草生长。
