| Abstract: The effect of annual high efficiency cultivation model of ginger on cultivars, yield and agronomic traits of ginger was studied from the viewpoint of cultivation measures. The results showed that the annual high efficiency cultivation model of 'Laiwu big ginger' and 'Laiwu small ginger' were 60% and 40% higher than that of the common cultivation model, respectively. The growth of ginger at 24 ℃ and the distance between heating layer and ginger seed 5 cm was better than that of other spacing (15 cm and 10 cm) and different ground temperatures. Under this condition, the ginger showed high yield, large growth quantity, strong growth potentiality and good quality. The agronomic traits of ginger, such as plant height, effective leaf number, fresh weight of rhizome, stem diameter, branch number, were obviously promoted. Annual yield of 3 stubble cultivations treatment was the highest. The effect of annual high efficiency cultivation model on ginger growth mainly provided suitable growth factors, especially ground temperature conditions for ginger, thus breaking the barrier of natural dormancy of ginger, improving growth and realizing annual production. The effects of increasing yield on different cultivars were different. |
