Analysis of Growth Characteristics and Physiological Disorder of Korean Ginseng Affected by Application of Decomposing Plant Residues in Paddy-Converted Field
pp.140-146
This study was carried out to investigate the difference of the content of soil chemical components and growthcharacteristics in six years old ginseng affected by application of decomposing plant residues in paddy-converted field. Theresults show that aerial parts of ginseng are no difference between press cake (PC) 200㎏/10a and control but subterraneanparts of ginseng PC 200㎏/10a, especially quantity related root fresh weight and tap root diameter, are statically about 1.6times heavier and about 1.2 times thicker than the ginseng control. Furthermore, the survival rate of PC 200㎏/10a is67.1% rise significantly compare with the control 50.7%. But compared with the PC 200㎏/10a and the PC 400㎏/10a,ginseng root growth and survival rate of PC 400㎏/10a get worse and that increase physiological disorder occurrence ratethan PC 200㎏/10a. Even though there are no significant differences between the ginseng of decomposing plant residuesexcept press cake treatment and the ginseng of control in growth characteristics, it does tend to increase the survival rateand decrease the physiological disorder occurrence rate in most fertilizer treatment except for RSC 2ton/10a, RSC 4ton/10a and RH 4kL/10a. Noted that EC is highly increased and exceeded 1.7ds/m in RSC 2ton/10a, RSC 4ton/10a and RH4kL/10a. It would be caused physiological disorder in many ways and affected ginseng growth characteristics, survival rate.
