In order to explore the characteristics of fruit vegetable production in Beijing，this study used
descriptive statistical method to analyze the survey data gained from on spots investigation of fruit vegetable farmer
households in Beijing．Then on this base，this paper studies how planting scale，planting technique，circulation
channel，market infrastructure construction，farmer cooperative and supporting policy on vegetable production
affect fruit vegetable production and management．This study also compares the fruit vegetable production in
2012 with that in 2015，so as to study the development and change of fruit vegetable production in Beijing in
recent 4 years from a dynamic perspective．The major conclusions are as following：1）business entity of fruit
vegetable production and management in Beijing is farmer households of small scale，2）there is a remarkable
aging tendency in farmer households engaged in vegetable production，3）there is a growing requirement for new
planting technology，4）the land scale， planting technology，market infrastructure construction and government
policies have significant positive effect on vegetable production，5）government support for fruit vegetable industry
is consistently increasing．
Horticulture crops grown in protected facilities were more sensitive to root zone temperature than
to air temperature and changes in root zone temperature could cause drastic physiological and ecological changes
in crops. This paper systematically summarized the effects and function machenism of root zone temperature on
physiological ecology of root system and canopy of crops grown in protected facilities. The paper reviewed the
progress made in studying the method and technology for adjusting root zone temperature， the existing problems.
Before ending， it also prospected the future research direction.
Recently，a mass outbreak of tomato bacterial pith necrosis occurred in Guangxi，except bacterial
wilt，Fusarium wilt and root-knot nematode．This experiment compared and identified 20 pieces of tomato rootstock
material from Guangxi，and screened rootstock material with multi-resistance to tomato bacterial pith necrosis．The
results indicated that rootstocks T034 and T103 were not only resistant to bacterial wilt，Fusarium wilt and root-knot
nematode，but also to bacterial pith necrosis，belonging to multi-resistance polymerization material．
For in-depth understanding the feature and correlation of seed phenotypic traits of faba bean
germplasm resources，comprehensive analyses were conducted in combination with correlation analysis，principal
component analysis and cluster analysis，etc. taking domestic and overseas 554 sets purified for 1 generation
of faba bean germplasm resources by insect nets as material，on seed phenotypic traits obtained from digital
equipment of seed examination. The results revealed that the tested seed phenotypic traits of faba bean germplasm
resources had a wide range variation and rich genetic diversity，especially in the trait of 100-seed weight.
Correlation analysis found that there was high correlation among 6 phenotypic traits of seed，including 100-seed
weight，seed projection area，perimeter，seed length，seed width and diameter；and the correlation coefficients
were greater than 0.80，reaching extremely significant level. The principal component analysis of 8 quantitative
traits showed that the component contribution rate of the former 3 components were 74.60%，23.09% and 1.70%，
respectively，with the cumulative contribution rate of 99.39%，almost covering the whole information of the
quantitative traits of the tested seeds. The variation of the above mentioned 6 phenotypic traits contributed largely to
the first principal component，which were all seed size characters. The cluster analysis showed that all the tested
material were classified into 3 groups associated with sowing time and geographical origin to some extent. Based on
the comprehensive analyses of seed phenotypic traits，11 genotypes with nearly spherical seeds and 8 genotypes
with high yield potential resources were selected for faba bean genetic improvement suitable for mechanized
production，and vegetable faba beans with high yield.
Through multiple spots experiments from 2014-2015， this study carried out test for screening
low cadmium accumulation watermelon varieties on cadmium polluted soil，and analyzed the cadmium contents
in watermelon vine，leaf，root and fruits．The results showed that the average cadmium content in vine was
0.057 0 mg·kg-1，in leaf was 0.062 1 mg·kg-1，in root was 0.054 8 mg·kg-1，in fruit was 0.009 2 mg·kg-1
．The cadmium contents in fruit of tested watermelon varieties were all below GB18406.1—2001 Agricultural
Product Safety and Quality Pollution Free Vegetable Safety Standards（cadmium ＜ 0.05 mg·kg-1）．
The cadmium content in different parts of watermelon was leaf ＞ vine ＞ root ＞ fruit．In soil，the cadmium
content was within the range of 0.310-9.480 mg·kg-1．Along with the increase of cadmium content in soil，
cadmium content in watermelon fruit would increase gradually．When the cadmium content in soil was below 9.480
mg·kg-1， the following 8 watermelon varieties‘Xiangxigua No.11’（‘Dongting No.1’），‘Xiangxigua No.19’
（‘Dongting No.3’），‘Jinlihuang’，‘Lyuhu’，‘Mitong’，‘Dongfangjiaozi’，‘Quanxin No.2’，‘Heimiren’
could be used as the optimal selection of cultivated land restoration and planting structure adjustment in cadmium
polluted area．
Taking tomato（Lycopersicon esculentum Mill.）cultivar‘Zhongza105’as experimental
material，this paper studied the effects of different sun-shade nets and tranditional black sun-shade nets on
inside light and temperature environment，tomato seedling growth and physiological properties．The result
showed that with the decreasing of shading rate，photon flux density（PFD），air temperature，5 cm and 10
cm soil temperatures all showed an increasing tendency．Compared with the 50% shading rate of black net，the
transmittance of 50% white net was remarkably different．The black sunshade net has higher UV transmittance
rate and there were not much differences between the transmittance rates of infrared light and visible light．While
the transmittance rates of UV light and part of infrard light of white sun-shade net was significantly lower than
the visible light．Therefore，the white sunshade net used as outside shading net of greenhouse could have better
cooling effect．Along with the decreasing shading rate，both black and white net treatments were all helpful for
increasing plant height，stem diameter，leaf area，total biomass，sound seedling index，root system activity and
foliar blade thickness of tomato seedling．Summing up the above，in summer according to the actural condition of
tomato seedling development，sunshade nets with shading rate between 20%-40% might be a good choice，among
them the white sun-shade net with 20% shading rate had the better effect．
Integrative water and fertilizer planting system for pakchoi〔Brassica campestris L. ssp.
chinensis（L.）Makino var. communis Tsen et Lee〕was designed using the non-woven fabric as growing
media．Taking‘Yangzhouqing No.1’and‘Gaogengbai’as material，this experiment studies the effects of
different nutrient solution concentrations on growth and physiological indexes of pakchoi by split block design．
The results indicate that along with the increase of nutrient solution concentrations，the overground fresh weight，
soluble sugar content and chlorophyll SPAD value will firstly increase and then decrease，while the root MDA has
an opposite tendency-firstly decrease and then increase．125% full price nutrition solution treatment is in favour of
upgrading overground fresh weight，soluble sugar content and chlorophyll SPAD value，and maintaining low root
MDA value of pakchoi．
Taking 5 pepper of different genotypes as experimental material，after artificial inoculating heavy
mosaic strain CMV，we tested the temporal change of CMV content in 5，10，15，20，25，30 days by DASELISA．
At the same time，the artificial classification method was used，and we carried out analysis on the
correlation of data gained through these 2 methods．The results showed that the virus content increased at 5，
10，15 days in turn，reached the highest level at 15 days．Then，the virus content reduced slightly．The virus
content of the plants obtained by DAS-ELISA was positively correlated with the disease index obtained by artificial
inoculation．The results obtained by the 2 methods were consistent.
In order to evaluate control effect of Bacillus vallismortis on gray mold of antagonistic bacterium
strain NBIF-001，this paper determined its inhibition activity to the pathogen of Botrytis cinerea by dual culture
method combined with optical microscope observation；and studied its controlling effects on cucumber leaf grey
mold and tomato fruit grey mold by in vitro tissue test．The results showed that the strain NBIF-001 had high
inhibition activity in dual culture．Optical microscope study revealed deformation of hyphal and enlargement
of cytoplasmic vacuoles．In vitro tissue test shew that NBIF-001 exhibited better biological control effect on
cucumber and tomato gray mold．The control effect reached 85.91% and 72.52%， respectively．
Germination is one of the main reasons causing potato storage loss. In order to investigate the
sprout inhibition effect of mint essential oil on storaged potato breeder seeds，this paper designed 4 mint essential
oil concentration gradient（0，20，50，80 μL·L-1） to treat 3 potato breeder seeds of‘ Yunshu 603’、
‘Yunshu 401’ and‘ Ziyun No.1’，and measured their germination rates and bud lengths of potato tubers at 0，
13，41，48，66 and 91 days after storage，respectively. The results showed that compared with the contrast， the
germination rate and bud length of these 3 potato varieties were significantly decreased after 3 months treatments
by mint essential oil and storage under room temperature. When the mint oil concentration reached 80μL·L-1，
the germination rates and bud lengths of these 3 potato varieties were all lower than that of the other treatments，
showing the rule of the higher concentration of mint essential oil，the more obvious of sprout inhibition effect. But
the sprout inhibition effects of‘ Yunshu 401’ treated with the concentration of mint essential oil by 20μL·L-1 and
80μL·L-1 were better than that by 50μL·L-1，showing the fact that besides the concentration of mint essential
oil concentration，the potato variety was also related with the sprout inhibition effect.
