The experiment was to explore the effect of stubble height on quality of silage corn. Yayu Silage No. 8 was selected for experiment. It was planted in random groups and harvested at the waxy ripening stage. Four stubble height treatment groups (group Ⅰ, group Ⅱ, group Ⅲ and group Ⅳ) were set up, including 15, 25, 35 and 45 cm, and each treatment group was set up with three replicates. Crush and bag after harvest, and measure the quality after 90 d of silage. The results showed that the crude protein content of Yayu Silage No. 8 increased with the increase of stubble height, and the crude protein content in group Ⅳ was significantly higher than that in group Ⅰ, group Ⅱ and group Ⅲ (P<0.05). The content of ADF and NDF in group Ⅰ was significantly higher than that in group Ⅳ (P<0.05). Compared with group Ⅰ, TDN, NEm and NEg in group Ⅳ were significantly increased (P<0.05). With the increase of stubble height, the non-fibrous carbohydrate and non-structural carbohydrate showed an upward trend (P>0.05). The content of non-fibrous carbohydrate in group Ⅳ was significantly higher than that in group Ⅰ (P<0.05). The degradation rate of DM, NDF and CP in group Ⅳ was significantly higher than that in other groups (P<0.05). The study indicates that the suitable stubble height of Yayu Silage No. 8 in Zhanjiang is 35~45 cm. [ABSTRACT FROM AUTHOR]

The northeast black soil region has been one of the most important main grain producing areas and commodity grain production bases in China. A great task is to realize the national grain supply and security. The typical black soil has the excellent soil characteristics and high fertility. However, the high-intensity utilization mode of arable land is widely used in the grain production under the ever-increasing demand with the acceleration of industrial development and urbanization. Although this approach can improve the grain output in a short period of time, the cultivated land pressure (such as shallower surface layer and quality decline) is gradually appeared in the black soil area. Therefore, it is very urgent to protect the black soil areas, as issued by the Outline of the Plan for the Protection of Black Soil in Northeast China (2017-2030) in 2017. This study aims to clarify the cultivated land pressure in the black soil area of Northeast China under different scopes of food security. The 21 typical black soil counties and districts were selected using the statistical data from 2004 to 2019. A modified model of cultivated land pressure index was established to calculate the cultivated land pressure index. The grey-BP network combined with the forecasting model was used to predict the change trend of cultivated land pressure in the next five years. Some suggestions were also proposed for the black land protection. The results show: 1) The cultivated land pressure was generally better in the typical black soil area of Northeast China from 2004 to 2019. But, there were still some areas with the "false security" phenomenon, due to the high intensity of cultivated land use pattern. The severe pressure constraints were found in the black soil of the cultivated land. The dynamic change of cultivated land pressure was negatively correlated with the quality of cultivated land, actual per capita cultivated land area, as well as social and economic development level. Therefore, the cultivated land pressure gradually increased with the expansion of food security. 2) A typical northeast black soil area of cultivated land was found to effectively relieve the national pressure from 2020 to 2024. But, the low and medium pressure level was observed in the Nehe, Changtu counties, whereas, the Baiquan county was in a high pressure rise. The Yian County was depended mainly on the rural social and economic development. Specifically, the pressure was in the good condition before 2023, but the subsequent trend indicated the pressure warning. 3) The pressure of cultivated land can be expected to represent the pressure of food security, but the pressure of food security cannot accurately reflect the pressure of cultivated land. Short-term high-intensity use of cultivated land can lead to the “deceptive” performance of cultivated land pressure. A low pressure of cultivated land was found at first, but the long-term role failed to ensure the food security with the gradual reduction of the fertility. 4) The measurement demonstrated that the current refined and improved policy was achieved in the pilot implementation of soil protection and utilization. Consequently, the pressure of arable land can be effectively relieved, even though there was a certain lag in the project. The index of cultivated land pressure was divided into four levels. Different protection suggestions were proposed to adjust the measures for the better policy benefits, according to the local conditions in the various soil pressure areas. [ABSTRACT FROM AUTHOR]

BACKGROUND: Traditional dialysis membranes are mostly synthesized by organic polymer materials. Although these materials can meet the needs of treatment, the pore size range is large and the microtubules are not uniform, which can cause protein clogging on the dialysis membrane. Therefore, it is difficult to achieve the expected therapeutic effect. OBJECTIVE: To study the hemocompatibility of titanium dioxide nanotube bio-dialysis membrane. METHODS: High-strength titanium dioxide nanotube films were prepared by anodic oxidation method, the bottom of the nanotubes was etched by HF gas, and the LLC-PK1 and ECV304 cells were seeded onto the prepared titanium dioxide nanotube array membranes to construct two kinds of titanium dioxide nanotube bio-dialysis membranes. Hemolysis test, dynamic clotting time test and platelet adhesion test were used to determine the hemocompatibility of the prepared titanium dioxide nanotube bio-dialysis membrane. RESULTS AND CONCLUSION: In the hemolysis test, the hemolysis rates of the titanium dioxide nanotube array membranes carrying LLC-PK1 and ECV304 cells were lower than that of the polyurethane material (0.30%, 0.34%, 0.56%; P < 0.05). In the dynamic clotting test (20, 40, 70 minutes), the dynamic clotting time of the titanium dioxide nanotube array membranes carrying LLC-PK1 and ECV304 cells were significantly longer compared with the polyurethane material (P < 0.05). In the platelet adhesion test, the platelet adhesion rate showed no significant difference between the polyurethane material and the titanium dioxide nanotube array membranes carrying LLC-PK1 and ECV304 cells (P > 0.05). These findings indicate that the titanium dioxide nanotube bio-dialysis membrane possesses good hemocompatibility. [ABSTRACT FROM AUTHOR]

Scrophulariae Radix is one of the most popular traditional Chinese medicines (TCMs). Primary processing of Scrophulariae Radix is an important link which closely related to the quality of products in this TCM. A method of ultra high performance coupled with triple quadrupole liner ion trap mass spectrometry (UPLC-Qtrap-MS/MS) was established for the determination of iridoid, phenylpropanoid glycosides and organic acids in Scrophulariae Radix. The goal of the method was to investigate the influences on multiple active constituents with different processing methods of Scrophulariae Radix. Twelve multiple active constituents in Scrophulariae Radix with different processing methods were simultaneous determined by UPLC-Qtrap-MS/MS, and grey incidence degree method analysis was performed to evaluate the different processed samples according to the contents of twelve multiple active constituents. The analysis was carried out on an BDS HYPERSIL C18 column (250 mm×4.6 mm×5 μm), with elution of acetonitrile-water as mobile phase at a flow rate of 1.0 mL/min. The column temperature was 35 ℃. The target compounds were analyzed by the negative ion multiple reaction monitoring (MRM) mode. The results show that twelve multiple active constituents have good linearity (r≥0.999 0) in the range of the tested concentration. The average recoveries of the twelve components are 95.82%-99.35% with the relative standard deviations less than 2.44%. There are differences in multiple active constituents of Scrophulariae Radix with different processing methods and the processing method of air drying method and complete root by oven drying after steaming had a better quality. The method is useful for the overall assessment on quality of Scrophulariae Radix, and this study may provide the foundation and support for processing method of Scrophulariae Radix in normalization and standardization.
