Yanbian Academy of Agricultural Sciences
December, 1998
1.
Aim of the Experimental
The experiment is to demonstrate the efficacy of Power fertilizer
in soybean by comparing with other foliar fertilizers and
provide scientific basis for the application and extension
of this product.
2. Materials and methods
Power fertilizer: Produced by Zhejiang;
Ti-micronutrient Fertilizer: Produced by Liaoning.
Gaomeishi: Produced by USA.
Wang ping san£ºProduced by Wangqing, Jilin.

Treatments and experimental design
4.1 Power:
4.1.1 Soaking seed at rate of 20ml Power product /kg seed
4.1.2 Spraying with 700 time dilute of Power at the initial
stage of flowering
4.1.3 Spraying with 700 time dilute of Power at the flourishing
stage of flowering
4.2 Ti-micronutrient Fertilizer
4.2.1 Soaking seed at rate of 7.5ml/kg seed
4.2.2 Spraying with 500 time dilute of Ti-micronutrient at
the initial stage of flowering
4.2.3 Spraying with 500 time dilute of Ti-micronutrient at
the flourishing stage of flowering
4.3 Gaomeishi
4.3.1 Spraying with 400 time dilute of Gaomeishi at the initial
stage of flowering
4.3.2 Spraying with 400 time dilute of Gaomeishi at the flourishing
stage of flowering
4.2 Wangpingsan Fertilizer
4.2.1 Soaking dressing at ratio of 1: 200.
4.2.2 Spraying with 200 time dilute of Wangpingsan at the
initial stage of flowering.
4.2.3 Spraying with 200 time dilute of Wangpingsan at the
flourishing stage of flowering.
4.5 CK: water
5. Results and analysis
Results from 5 sites experiments in 1997-1998 showed that
the average yield in Power plots was 2986.98kg/ha, and that
the yield increased by 19.02% compared with CK£¬by 36.54% compared
with Ti-micronutrient£¬and by 7.97% compared with Wangpingsan,
respectively (table 1).
The results also showed that the number of bean pods/plant
in Power plots was 71.9, increasing 19.9 plant/plant compared
with CK£¬that the average number of soybean grain in Power
plots was 169/plant, increasing 54.8 bean grains compared
with CK, and that the average number of bean grains in each
bean pod was 22.5 and the mean weight of hundred bean grains
was 20.7g, increasing 1.0g compared with CK.
Two years' results obtained in 6 site experiments indicated
that Power treatment increased soybean plot yield by 19.2%.
