摘要:

针对我国大蒜常规种植密度较小、生长空间较大,造成土地资源浪费的情况,开展了田间小区试验,考察了不同种植密度对大蒜生长的影响。结果表明:宽窄行(行距25 cm/15 cm)处理的大蒜在整个生长期的表现优于等行距(行距20 cm)处理的;与对照(CK)处理相比,在大蒜收获期,株距9 cm的宽窄行(T4)处理的单株鲜质量、蒜头径分别显著提高了13.8%、7.0%;直径60 mm以上的大蒜占比最高的是株距12 cm的宽窄行(T3)处理和T4处理,均为66.7%;T4处理的大蒜商品产量最高,比CK处理的提高了1 376.85 kg/亩,经济效益较好。结合全生育期整体长势、产量和经济效益,株距9 cm的宽窄行处理的效果较理想。

Abstract:

In connection with the situation of small garlic planting density and large growth space in China, which causes waste of land source, the field plot experiment is carried out and the effect of different planting density on the growth of garlic is investigated. The results show that the garlic treatment with wide-narrow row (row spacing 25 cm/15 cm) is better than that with equidistant row (row spacing 20 cm) treatment throughout the whole growth period. Comparing with the control treatment (CK), in the harvest period of garlic, the fresh weight and the diameter of the garlic head of wide-narrow row treatment with 9 cm plant spacing (T4) are significantly increased by 13.8% and 7.0%, respectively. The highest proportion of garlic in diameter of more than 60 mm is the treatment of wide-narrow row with 12 cm plant spacing (T3) and T4 treatment, all of which are 66.7%. T4 treatment has the highest commercial output of garlic, which is 1 376.85 kg/mu higher than that of CK treatment, and has better economic benefits. From the perspective of overall growth during the whole growth period, yield and economic benefits, the treatment of wide-narrow row with plant spacing of 9 cm is ideal.
