Ordered porous block copolymer films（PBCFs） have attracted much attention because of their potential applications in several fields. In this paper, we first reported a non-destructive, controllable, and efficient approach for preparation of β-cyclodextrin（β-CD）-functionalized PBCFs（β-CD-PBCFs）. The key point of the approach is to incorporate β-CD units into the hydrophilic segment of amphiphilic block copolymers before the preparation of films. β-CD-PBCFs with structural integrity and controllable pore parameters were fabricated through combining of self-assembly and breath figure methods. And then, the effective adsorption capacity of β-CD-PBCFs toward Congo red was confirmed through UV-Vis spectroscopy and was found to be affected by β-CD content and solution p H values. Adsorption kinetic results showed that the adsorption behavior of β-CD-PBCFs was consistent with the pseudo-second-order kinetic model and the chemisorption mechanism.

Based on the distance of interval numbers and the two-stage decision methods, this paper expands the decision model of grey target into some situation under which the decision information and target weights are the interval numbers at the same time. It also gives the optimization method of weights in the grey target. We get the optimum coordinated vector utilizing the combination assigning method, based on the local optimization of various schemes. So it can shift the weights of interval number into real number form and sequence it according to the weighted off-target distance. Finally the effectiveness and practicality of the model is proved by a real project.

To identify a strategy for earlier sowing and harvesting of spring maize(Zea mays L.) in an alternative maize–maize double cropping system, a 2-year field experiment was performed at Quzhou experimental station of China Agricultural University in 2014 and 2015. A short-season cultivar, Demeiya number 1(KX7349), was used in the experiment. Soil temperature to 5 cm depth in the early crop growth stage, crop growth, crop yield, and water use of different treatments(plastic film-mulched raised bed(RF) and flat field without plastic film mulching(CK) in 2014; RF, plastic film-mulched flat field(FF), and CK in 2015)were measured or calculated and compared. Soil temperature in the film-mulched treatments was consistently higher than that in CK(1.6–3.5 °C in average) during the early growth stage. Crops in plastic film-mulched treatments used 214 fewer growing-degree days(GDDs) in 2014 and 262 fewer GDDs in 2015. In 2014, the RF treatment yielded 32.7%higher biomass than CK, although its 9.4% higher grain yield was not statistically significant. Also, RF used 17.9% less water and showed 33.1% higher water use efficiency(WUE) than CK. In 2015, RF and FF showed 56.2% and 49.5% higher yield, 15.0% and 4.5%lower water use(ET), and 63.4% and 75.7% higher WUE, respectively, than CK. RF markedly increased soil temperature in the early crop season, accelerated crop growth, reduced ET,and greatly increased crop yield and WUE. Compared with FF, RF had no obvious effect on crop growth rate, although soil temperature during the period between sowing and stem elongation was slightly increased. However, RF resulted in lower ET and higher WUE than FF. Effects of RF on soil water dynamics as well as its cost-effectiveness remain topics for further study.

挥发油作为藿香的药效成分,积累并储藏在腺鳞中。以胡薄荷酮型藿香的叶片为材料,对藿香不同生长时期的叶片进行形态学观察,并通过GC-MS检测分析腺鳞中的挥发油成分。同时采用qRT-PCR技术测定挥发油中单萜生物合成途径中关键酶基因的相对表达量。结果表明,藿香腺鳞的密度呈现先下降后趋于平稳的趋势。随着藿香叶片的不断生长,腺鳞中胡薄荷酮的相对含量由79.26%降至3.94%(89.97%~41.44%),而异薄荷酮的相对含量则由2.43%上升至77.87%(0.74%~51.01%),其他成分的变化相对不明显。单萜类成分相对含量与其关键酶基因相对表达量的相关性分析表明,薄荷酮、异薄荷酮的相对含量与胡薄荷酮还原酶(PR)的相对表达量存在显著的相关性(r>0.6,P<0.01)。综上所述,该研究揭示了藿香腺鳞内含物的主要成分的积累规律及其生物合成关键酶基因的表达规律,为藿香药材合适采收时期的确定及质量控制提供了科学依据和数据支撑,并初步揭示藿香中以胡薄荷酮和异薄荷酮为主的单萜类成分的生物合成机制,为后续研究藿香中单萜类成分合成积累的分子机制的深入研究奠定基础。
