There is increasing effect of hundred-pod weight employed only in legumen forming stage and with the level of 30kg/hm2, and the level of 30kg/hm2 also have increasing effect for hundred-seed weight in acicula forming and legumen forming stage. Foundation fertilizer with 30kg/hm2 level increasing the quantity of per plant; employing silicon has no significant effect on fat concentration, so silicon is applicable to edible species. Employing silicon make significant descend of plant nitrogen, significant increasing of plant phosphorus only with level of 90kg/hm2 applying before planting, decreasing of that only with level of 150kg/hm2 employing in legumen forming period, and no distinct effect with others levels. Comprehensive effect of plant potassium, and that should do better in future.
仅在结荚期施用30kg/hm2硅提高花生的百仁重;在下针期和结荚期施用30kg/hm2可提高百果重;基施(30kg/hm2)提高产量的主要原因是增加了单株结荚数;花生施用硅肥后对花生仁的脂肪含量没有明显的影响,花生施硅适宜于食用型品种;花生施用硅肥能明显降低花生成熟期植株的全氮含量;对磷的影响则表现为,基施硅肥90kg/hm2可提高植株中磷的含量,而结荚期追施150kg/hm2的处理降低植株中磷的含量;对钾的影响则表现为复杂的规律,其机理需进一步研究。

Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.
在磷胁迫[0mmol/L,砂培]条件下,对不同基因型大豆苗期在根系形态、生物量等方面的差异进行了研究,结果表明:磷高效基因型在两叶期并未发挥出其基因型潜力的优势;四叶期,磷高效基因型的侧根数、侧根长、根系吸收面积、茎叶干重等性状的受抑制程度均显著低于磷中、低效基因型,而地下干重、根冠比却受到了较中、低效基因型更强的诱导作用。

In the past, researches focused only on sole function of bacteria such as tricalcium phosphate or ferric phosphate solubilization. In order to efficiently develop superior phosphate solubilizing microorganisms which are useful on various crops, a team includes Professors C.C. Young, C.C. Tang, S.H. Su, H.J. Chen and C.T. Lo in National Chung Hsing University and National Formosa University was established. Microbial consortiums include phosphate solubilizing bacteria, phosphate solubilizing actinomycetes, phosphate solubilizing yeast, and phosphate solubilizing fungi will be designed in the present study and their capabilities to promote crop growth will be demonstrated. The suitable phosphate solubilizing bacterial formula will also be designed. Consideration for the specificity and adaptation of phosphate solubilizing microorganisms to their host crops, the designed biofertilizers will be used as inoculants to increase the yields of various crops meanwhile reduce the overdose usage of chemical fertilizers.
