    In recent years,Chinese protected vegetable(CPV)soils have degenerated widespreadly.
    The soil is firm and compacted,with secondary salinization,imbalanced nutrient,heavy metals pollution and
    increased soil borne diseases,etc.At present,although studies on soil CPV properties of protected vegetable
    fields in China have made significant progress,most studies primarily focused on the single index in terms
    of soil physical,chemical and biological properties,and microorganism characters,etc.While,studies
    on comprehensive evaluation of soil quality is lacking.This paper reviewed the internal and external studies
    related to soil quality of protectes vegetable fields;and comprehensively analyzed the soil quality of protected
    vegetable fields on the basis of combining soil physical,chemical and biological properties.Besides,the
    paper also briefly introduced the soil over all quality evaluation methods,hoping to provide references for indepth
    evaluation on soil quality of protected vegetable fields.

    TCP is a class of transcription factors unique to plants and plays an important role in plant
    growth and development.Selecting 18 TCP members highly expressed in tomato leaf tissue,this study detected
    their expression levels at different development stages;and screened out 10 TCP family members related to
    leaf blades development process,including SlTCP2,SlTCP4,SlTCP8,SlTCP11,SlTCP14,SlTCP15,
    SlTCP19,SlTCP22,SlTCP24,SlTCP25
    ,etc..Then bioinformatic analysis was performed on them.The
    results indicated that these 10 SlTCPs members were distributed in 8 different chromosomal locations.There
    were relatively larger differences in their length of basic group,amino acid and molecular weight.And all
    of the TCPs were unstable hydrophilic proteins.Analysis of SITCPs protein structure and element indicated
    that in center about 50aa length amino acid sequences were relatively well conserved.Moreover,serine took
    relatively larger proportion.The site prediction of SlTCPs protein subcellular fraction were all localized on the
    nucleus.The above mentioned SlTCPs protein all contained the conserved domains of typical TCP family.
    Its classification of conserved motif was consistent with the branching of phylogenetic tree.Results of tissue
    expression analysis showed that SlTCP11,SlTCP15 and SlTCP24 all had relatively higher expression levels
    in different tissues and organs at each stage.Using typical tomato leaf shape mutant materials LA2922 and
    LA2532 and their corresponding wild types,this experiment conducted qRT-PCR.The results indicated that
    the expression levels of SlTCP2,SlTCP11,SlTCP14,SlTCP15,SlTCP19 and SlTCP24 in leaf blades of
    LA2922 and LA2532 were in the opposit direction.Combining with the results of bioinformation analysis,it
    was specified that SlTCP2,SlTCP11,SlTCP14,SlTCP15,SlTCP19,and SlTCP24 might play a key role in
    the development of tomato leaf shape.This has laid foundation for further explorating the molecular mechanism
    of tomato leaf blades growth and development.

    Excessive application of nitrogen fertilizer will reduce crop quality and harm environment.
    How to reduce the nitrogen fertilizer applying dosage without reduction of output has become an issue urgently
    to be solved for agriculture development.Arbuscular mycorrhizae fungi(AMF) plays a positive role in
    promoting plant nutrient absorption,growth and development,and yet has the potential of replacing nitrogen
    fertilizer.Taking lettuce(Lactuca sativa L. var. ramose Hort.) and spinach( Spinacia oleracea L.) as research
    objects,this experiment set up 8 treatments with different nitrogen fertilizer dosage and 5 treatments with
    different AMF use level,respectively.This experiment screened out the best dosages of pure nitrogen fertilizer
    for lettuce and spinach growth being 6.0 kg · hm-2 and 8.0 kg · hm-2,respectively and the best use level of
    AMF were 200 g · kg-1 and 175 g · kg-1,respectively.Then AMF was used to replace the nitrogen fertilizer in
    different proportions.Afterwards,the paper studied the effect of AMF on reducing nitrogen fertilizer dosage
    in lettuce and spinach.The results showed that under the condition of substrate cultivation and on the premise
    of not reducing lettuce and spinach fresh weight,adding 200 g · kg-1 and 175 g · kg-1 AMF,respectively could
    reduce 40% and 60% nitrogen fertilizer dosage in lettuce and spinach production,respectively.That is,the
    nitrogen fertilizer dosages were 3.6 kg · hm-2 for lettuce and 3.2 kg · hm-2 for spinach,their plant growth were
    unaffected.The experiment result provided a new way for reducing nitrogen fertilizer application in lettuce and
    spinach and for high-quality cultivation as well.

    Under the condition of root restriction cultivation,taking normal drainage (20-EC1.6
    treatment)as the contrast,this paper measured tomato growth indexes,leaf photosynthetic parameters,
    fruit commodity characters,related metabolic enzymes and primary metabolites,etc. under the conditions of
    minimal drainage(0-EC1.6 treatment) and increasing nutrient solution concentration(0-EC1.6-2.4 treatment)
    or adding NaCl(0-EC1.6-2.4Na treatment) and studied the effect of extremely low drainage rate(ELDR)
    and nutrient concentration regulating on tomato fruit quality.The results showed that ELDR could significantly
    inhibit tomato plant stem thickening,leaf extension and fruit expanding,decreased leaf net photosynthetic
    rate(Pn),stomatal conductance(Gs),intercellular CO2 concentration(Ci),transpiration rate(Tr),
    single fruit weight and yield per plant.However,the contents of soluble solid matter,VC,lycopene,
    polyphenols,free amino acid and glucose/malic acid,fructose/citric acid in fruit were significantly increased,
    while the percentage of non-commercial fruit was decreased.ELDR combined with increasing nutrient solution
    concentration could further increase the contents of soluble solid matter, amino acid and its ramification
    (5-L-glutamyl-L-alanine),phenolic acid(coumaric aldehyde)and glucose/malic acid;and reduced noncommercial
    fruit rate.ELDR could significantly increase the activities of invertin and sucrose synthase,which
    were further remarkably increased by increasing nutrient solution concentration.Thus,catalytic decomposition
    of sucrose was made to produce glucose and fructose.Comprehensively considering various indexes,0-EC1.6-2.4
    was the optimum treatment for improving tomato fruit quality under root restriction cultivation condition.

    Aiming at the problems existed in current design and construction of solar greenhouses,
    including poor thermal accumulation capacity in wall,low land utilization rate,shortage of soil resources
    and slow construction speed,etc.,this paper innovatively designed a prefabricated solar greenhouse actively
    accumulating thermal by water module(GH1).The paper also conducted measurement and comparetive
    analysis on the indoor temperature,ground temperature and relative humidity between GH1 and ordinary solar
    greenhouse(GH2).The results showed that during the consecutive sunny days,the highest temperature at
    day time and lowest temperature of GH1 were 1.2 ℃ and 1.8 ℃ higher than that of GH2,respectively.And the
    average temperature at night was 1.2 ℃ higher,and average ground temperature of GH1 was 1.5 ℃ higher than
    that of GH2.During consecutive cloudy days,the average day time temperature of GH1 was 5.3 ℃ higher
    than that of GH2,4.0 ℃ higher at night,and average ground temperature was 2.0 ℃ higher.During extreme
    weather,the average temperature of GH1was 4.8 ℃ higher than that of GH2,and average ground temperature
    was 1.8 ℃ higher than that of GH2.The test results for 31 consecutive days showed that the average minimum
    temperature of GH1was 1.1 ℃ higher than that of GH2,and average night temperature was 3.8℃ higher than
    that of GH2.When it is sunny,the average relative humidity of GH1 was 14.7 percentage point lower than
    that of GH2.And when it was cloudy,it was 4.1 percentage point lower than that of GH2.In summary,the
    technical scheme for solar greenhouse actively accumulating thermal by water module is feasible, and its overall
    thermal accumulation performance is obviously better than that of the ordinary solar greenhouses.Especially
    under consecutive cloudy and extreme rain and snow conditions,it can maintain a higher indoor temperature
    and ground temperature.
