摘要

该研究在胡志明市农林大学农学院实验农场进行。研究了钾肥种类和用量对攀壤大蒜生长和产量的影响。双因素试验采用随机完全区组设计,8个处理,3个重复。因子A包括2种商品钾肥(KCl、K2SO4),因子B包括4种不同剂量钾肥(110 kg/ha、140 kg/ha、170 kg/ha、200 kg/ha)。结果表明,施用200 kg K2SO4/ha可使株高增加51.8 cm;200 kg/ha施钾处理大蒜的球茎直径(24.7 mm)、球茎瓣数(12.3瓣)、球茎重(4.83 g)、干物质率(92%)和球茎产量(1.36 kg/100盆)最高。

Effects of types and doses of potassium fertilizers on growth and yield of Phan Rang garlic variety (Allium sativum L.)
The study was conducted at the Experimental Farm of the Faculty of Agronomy, Nong Lam University, Ho Chi Minh City. The objective of the study was to determine the effects of type and dose of potassium fertilizer on growth and yield of Phan Rang garlic variety. The two-factor experiment was arranged in a randomized complete block design with 8 treatments and 3 replicates. The factor A included 2 types of commercial potassium fertilizers (KCl, K2SO4) and the factor B was 4 different doses of potassium fertilizers (110 kg/ha, 140 kg/ha, 170 kg/ha, 200 kg/ha). The results showed that the application of 200 kg K2SO4/ha increased the plant height (51.8 cm). Bulb diameter (24.7 mm), number of cloves/bulb (12.3 cloves), bulb weight (4.83 g), percentage of dry matter (92%) and bulb yield (1.36 kg/100 pots) were highest in the garlic plants with potassium application at 200 kg/ha.
