摘要
为探求不同种植密度对大蒜鳞茎形状、产量及经济效益的影响,以大名紫皮蒜、永年白蒜2个大蒜品种为试验材料,采用随机区组设计,各设6个密度处理水平,分析了不同种植密度对大名紫皮蒜、永年白蒜2个大蒜品种鳞茎形状、产量及经济效益的影响。结果表明,大名紫皮蒜、永年白蒜2个大蒜品种随着种植密度的增加,鳞茎单头重、直径逐渐显著降低,商品性逐渐降低,产量虽然逐渐增加,但经济效益却先升高后降低。根据密度与产量、利润拟合的曲线可以得出,大名大蒜种植密度为76.57万株/hm^(2)、永年大蒜种植密度为99.07万株/hm^(2)时,大名紫皮蒜鳞茎达到理论最大产量22965.80 kg/hm^(2)、永年白蒜鳞茎达到理论最大产量19026.45 kg/hm^(2);大名紫皮蒜种植密度为63.64万株/hm^(2)、永年大蒜种植密度为77.47万株/hm^(2)时,大名紫皮蒜鳞茎达到理论最大利润33589.98元/hm^(2)、永年白蒜鳞茎达到理论最大利润30230.48元/hm^(2)。综合分析可以得出,邯郸地区大名紫皮蒜适宜的种植密度为63.64万~76.57万株/hm^(2)、永年白蒜适宜的种植密度为77.47万~99.07万株/hm^(2)。
In order to explore the effects of different planting densities on garlic bulb characters,yield and economic benefits,Daming purple garlic and Yongnian white garlic were used as materials,6 density treatment were set up by use of randomized block design.The results showed that with the increase of planting density,the bulb weight and diameter of Daming purple garlic and Yongnian white garlic gradually decreased,and its commodity gradually decreased,the yield gradually increased,but the economic benefit first increased and then decreased.According to the curve fitting density with output and profit,when the planting density of Daming purple garlic was 76.57×10^(4) plants/hm^(2) and Yongnian white garlic was 99.07×10^(4) plants/hm^(2),the theoretical maximum yield of Daming purple garlic bulb was 22965.80 kg/hm^(2) and Yongnian white garlic bulb was19026.45 kg/hm^(2),when the planting density of Daming purple garlic was 63.64×10^(4) plants/hm^(2) and Yongnian white garlic was 77.47×10^(4) plants/hm^(2),the theoretical maximum profit of Daming purple garlic bulb was 33589.98 yuan/hm^(2) and Yongnian white garlic bulb was 30230.48 yuan/hm^(2).According to the comprehensive analysis,the suitable planting density of Daming purple garlic is 63.64×10^(4)~76.57×10^(4) plants/hm^(2) and that of Yongnian white garlic is 77.47×10^(4)~99.07×10^(4) plants/hm^(2) in Handan.
