摘要
白姜花作为香料植物由南亚热带引种到中亚热带栽种是成功的。为提高花的产量,已找出较为合理的N—P_2O_5—K_2O配比为3.4∶1∶3.1。以追肥方式,每公倾全年施用量N—127kg,P_2O_5—3.8kg,K_2O—117.6kg。栽种密度为5丛/m^2,每公倾鲜花量达36.085t。
The introduction of the spice plant coronarious gingerlily (Hedychium coronarium) from tropical South Asia to Central Asia was successful. In order to promote the flower yield a good proportion of the fertilizers applied is required. The authors found out that the rational formula of N: P2O5 : K2O was 3.4 : 1 : 3 .1, so an annual per ha dosage of after manuring with 127 kg of N, 3.8 kg of P2O5 and 117.6 kg of K2O was desirable. When the planting density was 5 clumps per square meter, the yield of fresh flower per ha could reach 36.085 tons.
