SU Yi，FENG Guojun，LIU Dajun，YANG Xiaoxu，YAN Zhishan，LIU Chang
Saline-alkali stress is one of the important factors restricting common bean industry
development．Screening identification index for alkali tolerance of common bean in seedling stage has
great importance in breeding alkali-tolerant common bean varieties and promoting common bean cultivation
in saline-alkali land．This experiment took 35 common bean varieties as test materials，simulated 60
mmol · L-1 NaHCO3 solution as alkali stress，and treated common bean seedlings．Ten indicators including net
photosynthetic rate，intercellular CO2 concentration，stomatal conductance，malondialdehyde content，plant
height，root length，and dry/fresh weight of the above-ground part and underground part were measured，
respectively．The identification indicators for alkali tolerance of common bean in seedling stage were screened
by principal component analysis，and alkali tolerance of common bean in seedling stage was comprehensively
evaluated by fuzzy membership function and clustering analysis．The results showed that alkali stress could
significantly inhibit the growth of common bean seeldings．Eight indicators including root length，dry/
fresh weight of the above-ground part，dry/fresh weight of the underground part，net photosynthetic rate，
intercellular CO2 concentration and stomatal conductance could be used as main indicators for rapid identifying
alkali tolerance of common bean in seedling stage．These 35 varieties were divided into 5 types with different
alkali resistance through sorting the comprehensive evaluation value（D value）and clustering analysis．
‘Fenguan’was alkali-resitant variety．4 varieties such as‘14-4-1-3’ were relative alkali-tolerant varieties．
13 varieties such as‘Chiyu No.21’were medium alkali-tolerant varieties．16 varieties such as‘44-1-1’were
relative alkali-sensitive varieties．‘Tailaibaitiao’was alkali-sensitive variety．

LI Xin，ZHANG Xu，LA Shikai，XIE Yingfei，CHEN Shijun，GAO Lihong，TIAN Yongqiang
In-situ incorporation of vegetable plant straw returning to fields can effectively avoid
resource waste and environment pollution，but there is short of microbial consortium（MC）capable
of degrading cucumber plant straw in actual production．Moreover，MC influence on crop growth is
undefined．Taking cucumber plant straw as test material，this experiment screened high-efficient MC capable
of degrading cucumber plant straw by special non-carbon culture medium and explored the efficacy of MC for
cucumber growth promotion．The results showed that the degradation rate of cucumber plant straw by MC
reached as high as 80.7%，and their degradation rates of cellulose，hemicellulose and lignin were 78.8%，
74.7% and 49.4%，respectively．The highest cellulase activity（0.110 4 IU）appeared on the 9 days after
treatment．The dominant communities in MC included 8 phyla and 12 genera．They could utilize 23 kinds
carbon source substances out of 31 kinds carbon source．33 single strains were isolated from MC，among
which 15 strains had the capacity of degrading cellulose．Results of seed and seedling tests showed that MC
could efficiently promote the growth of cucumber seed seedlings and seedlings when OD600 of MC reached
0.4．Taken together，the screened MC could not only effectively degrade cucumber plant straw，but also

MAO Xin，YUAN Wenfei，ZHANG Yi，LI Yaling，WEN Xiangzhen,HOU Leiping,BAI Longqiang，LI Yansu
The formed organic substrate planting-board（OSP）cultivation is carried out by using
larger size planting-board with planting holes produced by pressing agricultural organic waste substrates．
Those planting-boards were lined up in greenhouses by robotic arm for vegetable production．This model is
suitable for mechanized vegetables cultivation．In order to seek the effects of OSP model on growth，yield
and quality of vegetables，this paper took lettuce as test material；conducted cultivation experiment on OSP
（decomposed sheep manure∶pea straw = 2 V∶1 V），taking conventional soil cultivation as the contrast．
The results showed that the growth vigor of lettuce grown in OSP was obviously stronger than that in soil
cultivation．And root vitality，chlorophyll content，net photosynthetic rate，single plant fresh weight
above ground and total N，P and K accumulation were obviously increased than those in soil cultivation，
amplification was 34.85%，10.42%，14.98%，101.00%，98.16%，69.96%，78.48%，respectively．The
contents of VC，soluble protein，soluble sugar in edible parts were obviously increased than those in soil
cultivation．While nitrate nitrogen content was significantly reduced，indicating OSP cultivation model could

50 Studies on Regulating and Controlling Excessive Growth of Cucumber Seedlings  by CCC Applying Method and Irrigation Water Temperature
SANG Jiajun，JI Yanhai，LIU Mingchi，WU Zhanhui，WANG Liping，WANG Suna
Taking‘Jingyan 118’cucumber as test material，this experiment set 3 irrigation water
temperatures（10 ℃，15 ℃ and 22 ℃）and 2 CCC applying methods（foliage spray and along with water
irrigation）；studied the effects of irrigation water temperature and CCC applying method on cucumber seedling
growth，strong seedling index and chlorophyll fluorescence parameters of leaves；and explored the technology
for regulating and controlling excessive growth of cucumber seedlings．The results showed that treatments
with different CCC applying method and irrigation water temperature all could significantly reduce the plant
height of cucumber seedlings．The strong seedling index in along with water irrigation treatments were
higher than that of foliage spraying treatments．Under the same CCC applying method，reducing irrigation
water temperature could inhibit cucumber seedlings excessive growth to certain degree．But it would reduce
the SPAD value of leaves，and cause some damage to them．In a comprehensive analysis，the treatment
combining 200 mg · L-1 CCC concentration，along with water irrigation， and 22 ℃ irrigation water temperature
can effectively inhibit the excessive growth of cucumber seedlings，and achieve the best strong seedling
effect．This is a suitable regulating and controlling measure for strong cucumber seedlings．
