    B3 family genes are unique transcription factors in plants and participate in the process of plant stress resistance. Arabidopsis thaliana HSI gene(AT4G32010) is a member of B3 family. In this study, homozygous mutant hsi were obtained by using PCR. The expression of HSI gene in mutant is lower than that in wild type. Under drought and salt stress, the germination rate of wild type and mutant hsi decreased with the increase of mannitol and salt concentration. At the same concentration, the germination rate of the mutant hsi was lower than that of the wild type, and the difference was significant. The results indicated that HSI gene of Arabidopsis thaliana played a positive role in seed germination. Under drought and salt stress, there was no significant difference in root length between wild type and mutant. It is indicated that the HSI gene is involved in the growth process of the root, and the regulatory role of the gene needs to be further clarified.

    At present, there is a wide range of studies on the cultivated land protection policy, but there is no research on its own structure, so a study on the use of policy instruments for protecting cultivated land opens up a unique perspective for exploring the pathways and features of cultivated land protection. Through constructing a two-dimensional analysis framework of cultivated land protection policy in China, including the dimensions of policy instruments and policy objectives, 181 policy texts of cultivated land protection at national level were measured and coded by using content analysis method. The research showed that, there were more structural mandatory policy instruments and fewer economic-oriented and mutual influenced policy instruments in the cultivated land protection policy. In the trinity stage of cultivated land protection, as the proportion of structural mandatory policy instruments decreased, there was a deficiency in use of tax policy instruments. Therefore, the leading and radiating role of economic-oriented and mutual influenced policy instruments should be brought into full play, and the concept of Trinity conservation of quantity and quality of cultivated land should be strengthened, so as to promote the development and perfect of cultivated land protection policy.

    To explore the effects of different land use patterns on Soil Labile Organic Carbon(LOC),Carbon Pool Management Index(CMI) and crop yields,selecting the arable land(T1),grape land(T2),jujube orchard land(T3) and vegetable land(T4) in Xinzheng city of Henan province as case object,to compare and analyze the variations of soil labile organic carbon and carbon pool management index under the 4 typical land use patterns(arable land,grape land,jujube orchard land and vegetable land). The results indicated that,under different land use patterns,total organic carbon(TOC) of 0-60 cm soil layer existed obvious difference,and decreased with increasing soil depth,among them,TOC mass fraction of 0-20 cm soil layer differed greatly,T4,T3,T2 was increased 60.0%,53.3% and 13.3% than T1 respectively,and LOC and CMI were significantly improved compared with unused land(T0). The crop yields was positively correlated with available nitrogen,carbon library activity (L) significantly(P<0.05),but had no significant correlation with LOC and CMI, that may be caused by different statistical standards of crop yield. For the obvious different effects of different land use patterns on soil TOC,LOC and CMI,the LOC and CMI could be used as the evaluation index for different land use patterns and soil carbon pool quality.
