16 Research Progress on Cucumber Salt Tolerance and Salt Tolerance Related Genes
LAI Wei，HE Peng，XU Ming-yuan，CHEN Liang-hai，LIU Shi-qiang，YANG Yin-gui Hot!
Cucumber is one of the important greenhouse vegetables．Because of its fragile root
system，good atmosphere and shallow distribution，its adaptability to saline environment is lower．
Soil salinization has become a main limiting factor affecting its yield and quality．This paper described
the response of cucumber to salt stress and its basic salt tolerance mechanism from perspectives of
photosynthesis，ion toxicity，cell membrane and antioxidant enzymes，etc. angles；introduced the
research progress on cucumber salt tolerance related genes including genes related to Na+/K+ regulation，
plant hormone regulation and ROS regulation；and also pointed out problems existing in studying salt
tolerance of cucumber，aiming at providing theoretical references for revealing cucumber salt tolerance
mechanism and breeding of salt tolerant cucumber varieties

39 Screening of Resistant Germplasm of Tomato spotted wilt virus and Optimization of Artificial Identification Method
SHI Yan，MO Ning，QI Shi-ming，LIANG Yan Hot!
In this study，154 tomato materials，including 76 common tomatoes and 78 cherry tomatoes
were investigated twice for the disease indexes of Tomato spotted wilt virus（TSWV）in fields for 2 years，
and 14 of them were screened with stable resistance to TSWV．Molecular marker identification was carried out
by Sw-5 co-dominant SCAR marker on materials with disease resistance in fields．Three materials carrying
Sw-5 gene against TSWV were discovered．In order to shorten the artificial inoculation identification period
for TSWV，this study took disease resistant material H8 containing Sw-5 and susceptible material M82 as
study object；set up 4 inoculation periods for 4，6，8 and 10 true leaf blades；and conducted disease index
investigation and resistance grading 14，21，28 days after inoculation．The results showed that inoculation
during 6 true leaf stage，and conducting disease investigation 28 days after inoculation could effectively
identify plant resistance for TSWV．Matching with the effect of inoculation in 8，10 true leaf blades stage，the
efficiency of artificial inoculation for disease resistance identification was significantly promoted．

MA Jun-feng，ZHANG Chen，ZHANG Chun-yu，LI Xiao-yu，WANG Yong-zhi
The complete genome of Shallot yellow stripe virus（SYSV） Jilin isolate SYSV-JL（MN607702）
was cloned from SYSV infected tillering onion by RT-PCR．The complete sequence of SYSV-JL consisted of
10 427 nucleotides，and shared high sequence identity with 3 SYSV isolates that had submitted to GenBank
in many gene segments，but the sequence identity of nucleotide and amino acid in P1 gene was lower，
only sharing 69.5%-84.2% and 60.9%-76.9%，respectively．Further variation analysis showed that P1 gene
contained 369 variation sites，showing obvious high variation characteristics．Phylogenetic analysis indicated
that different SYSV isolates had distinct regional differences and the phylogenetic relationship between SYSV-JL
isolate and multiple Chinese isolates was closer．

FU Yan-xiang，LI Nai-hui，LIU Jia-yao，WU Feng-zhi
Taking tillering onion and tomato as material，this paper studied the effects of concomitant
tillering onion on tomato rhizosphere soil bacterial and fungal community constitution and structure using highthroughput
sequencing．Results showed that comparing with tomato monoculture，concomitant treatment
with tillering onion could change the bacterial and fungal community constitution in tomato rhizosphere soil．
Proteobacteria，Bacteroidetes，Actinobacteria，Acidobacteria，Firmicutes，Planctomycetes，Chloroflexi
were advantage bacteriophyta．Ascomycota，Zygomycota，and Basidiomycota were dominant fungal
phylum．At class level，the treatment of concomitant tillerng onion could significantly enhance the relative
abundance of Alphaproteobacteria with beneficial potential，while reduced that of Sordariomycete and
Eurotiomycetes．At the order level，concomitant tillering onion treatment could significantly enhance the
relative abundance of Sphingomonadales and Propionibacteriales，while reduce that of Microascales，
Onygenales and Xylariales．At the family level，concomitant tillering onion treatment could significantly
enhance the relative abundance of Nocardioidaceae，Microbacteriaceae，Sphingomonadaceae，Blrii41 and
Lasiosphaeriaceae，while reduce that of Microascaceae and Onygenaceae．At the genus level，concomitant
tillering onion treatment could significantly reduce the relative abundance of fake allescheria with pathopolesis
potential—Pseudallescheria，Kernia and Wardomyces．However，there was no significant effect on
rhizosphere soil bacterial，fungal community structure and biodiversity．

ZHANG Jun-feng，XIE Jian-ming，ZHANG Yu-xin，WANG Xiao-wei，LIU Sheng-ming
In the randomized block experiment，there were 5 treatments，including no fertilization（CK），
conventional fertilization（100CF），100% conventional fertilization + bio-organic fertilizer（100CF+SF），
90% conventional fertilizer + bio-organic fertilizer（90CF+SF），and 80% conventional fertilizer + bio-organic
fertilizer（80CF+SF）．This experiment studied the eff ects of partial substitution of chemical fertilizer by bioorganic
fertilizer on cucumber yield，output input ratio，quality，nutrient distribution and fertilizer utilization
rate．The results showed that the distribution rates of N，P and K in diff erent parts of plant were diff erent，
that in stem and leaf were the highest，followed by fruit and those in root was the least．Compared with the
treatment of conventional application of chemical fertilizer alone，reducing 20% of the common chemical
fertilizer + applying 400 kg · （667 m2） -1 bio-organic fertilizer had the better effect．Thus，the single fruit
weight and cucumber yield were increased，nitrate content of cucumber fruit was reduced，contents of soluble
sugar and soluble protein were increased，and product quality was improved，utilization rates of nitrogen，
phosphorus and potassium were all enhanced．

LI Hui，LI Nai-hui，CUI Wen-jing，YIN Jun-hui，CHEN Qing，WU Feng-zhi
The occurrence of fungal diseases induced by continuous cropping in protected field was closely
related to the changes in soil physichemical properties．Applying alkaline soil ameliorant could reduce the
damage of soil-borne diseases in protected fields of acidified soil．Taking protected field soil with 25 years’
continuous cropping on cucumber as test soil，and through pot experiment，this study compared the effects
of 2 kinds alkaline soil ameliorant，including 2.5 g · kg-1 of potassium humate（pH 8.5，HA）and fertilizer
of calcium silicon magnesium potassium（pH 9.96，SiCa）on cucumber growth and controlling Fusarium
wilt．The results showed that these 2 kinds of ameliorant，HA and SiCa had remarkbly increased the soil
pH by 0.10 and 0.24 unit，respectively，comparing with no application of ameliorant treatment；promoted
cucumber seedling growth；the effects of controlling cucumber Fusarium wilt had reached 45.8% and 51.3%，
respectively．Application of these 2 ameliorants had also significantly improved the soil exchangeable
potassium contents．Compared with HA，SiCa performed more outstanding effects in promoting cucumber
growth and inhibiting cucumber Fusarium wilt．
