目的
2
探究不同比例有机肥和化肥配施对二年生射干生长、产量和品质的影响,为实现射干的高产优质栽培提供科学的施肥依据。
方法
2
采用田间小区试验,设置5个不同比例有机肥配施化肥的处理模式,OM
0
(纯化肥施用)、OM
1
(30%有机肥配施化肥,有机肥使用量2 567 kg·hm
-2
)、OM
2
(50%有机肥配施化肥,有机肥使用量4 283 kg·hm
-2
)、OM
3
(70%有机肥配施化肥,有机肥使用量6 000 kg·hm
-2
)、OM
4
(100%有机肥施用,有机肥使用量8 567 kg·hm
-2
),测定不同施肥模式对射干农艺性状、药材产量、黄酮类成分含量、矿质元素含量及肥料利用率的影响。
结果
2
适当比例的有机肥配施化肥可增加射干叶片宽度并促进分蘖苗的产生,从而提高射干药材产量,OM

处理组比较产量增加6.65%和13.10%;有机肥配施比例过高则会导致产量下降。配施有机肥后,射干根茎中芒果苷、射干苷、野鸢尾苷、鸢尾黄素、野鸢尾黄素和次野鸢尾黄素的含量增加,且一定比例的有机肥有利于钾、铁、铜等功能元素含量积累。主成分分析结果表明,5个施肥模式下射干的综合品质排名由高到低为OM

结论
2
综合不同比例有机肥和化肥配施处理下射干的农艺性状、产量、品质指标及肥料利用率,建议在二年生射干生产上采用4 283 kg·hm

的有机肥用量与化肥配施,以促进射干产业的提质增产。
Objective
2
To investigate the effect of the combined application of organic fertilizer and chemical fertilizer at different ratios on the growth, yield and quality of two-year-old
Belamcanda chinensis
and provide a scientific basis for fertilization to achieve high yield and quality of this medicinal plant.
Method
2
In a field plot experiment, we designed five fertilization patterns with organic fertilizer and chemical fertilizer at different ratios: OM
0
(pure chemical fertilizer), OM
1
(30% organic fertilizer + chemical fertilizer, application of organic fertilizer at 2 567 kg·hm
-2
), OM
2
(50% organic fertilizer + chemical fertilizer, application of organic fertilizer at 4 283 kg·hm
-2
), OM
3
(70% organic fertilizer + chemical fertilizer, application of organic fertilizer at 6 000 kg·hm
-2
), and OM
4
(pure organic fertilizer, 8 567 kg·hm
-2
). The effect of different fertilization patterns on the agronomic properties, herb yield, flavonoid content, mineral element content, and fertilizer utilization rate of
B. chinensis
were determined.
Result
2
The combined application of organic fertilizer and chemical fertilizer at an appropriate ratio increased the leaf width and promoted tillering, thereby improving the yield of
B. chinensis
. The yield of OM
1
and OM
2
groups increased by 6.65% and 13.10%, respectively, compared with that of OM
0
group, while too high a proportion of organic fertilizer led to a decrease in yield. With organic fertilizer application, the content of mangiferin, tectoridin, iridin, tectorigenin, irigenin, and irisflorentin in the rhizomes of
B. chinensis
increased. Moreover, a certain proportion of organic fertilizer facilitated the accumulation of functional elements such as K, Fe and Cu. The results of the principal component analysis showed that the overall quality of
B. chinensis
was ranked in the order of OM
3
>
OM
2
>
OM
1
>
OM
4
>
OM
0
. The OM
2
group had the maximum accumulation of N, P and K and the maximum partial factor productivity of fertilizer.
Conclusion
2
According to the agronomic traits, yield, quality indexes and fertilizer utilization rate of
B. chinensis
under different fertilization patterns, we recommended to apply 4 283 kg·hm
-2
organic fertilizer in combination with chemical fertilizer to the production of two-year-old
B. chinensis
, so as to improve the quality and yield of
B. chinensis
.
