Effects of chemical fertilizer reduction and organic fertilizer substitution on yield and quality of Saposhnikovia divaricata
To explore the suitable fertilizing pattern for Saposhnikovia divaricata in the genuine producing area, a field trial was carried out to investigate the changes in the yield and quality of medicinal materials and soil in different fertilization patterns, such as organic fertilizer substitution(organic fertilizer+NPK fertilizer) and chemical fertilizer reduction(organic fertilizer+NPK fertilizer decrement and organic fertilizer+NPK fertilizer decrement+soil conditioner). The comprehensive analysis of all treatments was based on the medicine quality evaluation data set and soil quality evaluation data set, respectively, by CRITIC weight method. The results showed that(1) the yield of S. divaricate increased by 4.93%-12.67% under the organic fertilizer substitution mode, and the yield increased by 44.43% under the treatment of chemical fertilizer reduction YHT15, which was higher than that of the organic fertilizer substitution mode.(2) The quality of S. divaricate under the two fertilization modes was superior to the standard in the Chinese Pharmacopoeia, and the application of biochar was helpful to improve the quality of S. divaricate quality, with an increase of 82.83%-181.54%. CRITIC method analysis showed that fertilization treatments with high comprehensive scores were YHT15, YH30, and YH15.(3) Soil quality under the two fertilization modes was higher than that under the control. The fertilization treatments with higher comprehensive scores of soil quality were YHT15, YHT30, and YHT. The fertilization mode of adding biochar as soil conditioner, applying an appropriate amount of organic fertilizer, and reducing part of chemical fertilizer is the appropriate way to develop ecological plantation of S. divaricata in the Baicheng area in the western Jilin province. The specific fertilization mode is as follows. The basic fertilizer was 361 kg·hm~(-2) superphosphate+110 kg·hm~(-2) potassium sulfate+82 kg·hm~(-2) organic fertilizer+10 000 kg·hm~(-2) rice husk biochar, and urea was applied as top fertilizer three times, 29, 29, and 20 kg·hm~(-2), respectively.
