Greenhouse gases are ever increasing at the great risk of climate change in recent years. Climate change adaptation has been the most fundamental measure to achieve carbon neutrality. It is a high demand to reduce the agricultural carbon and nitrogen emission for water use efficiency during irrigation. In this study, a systematic investigation was made to clarify the effects of tillage systems on greenhouse gas emission and water use efficiency in farmland fields using the winter wheat-summer maize rotation system. The farmland experimental site was selected in the plot of the ninth production team of Zhoujiazhuang Town, Jinzhou City, Hebei Province of China. The test area was about 30 000 m² with a width and length of 91, and 330 m, respectively. A total of 54 plots were then divided into the experimental area, each with a randomly arranged area of 120 m² (8 m×15 m). The field experiment was performed on the different tillage and irrigation systems during the winter wheat-summer corn growing season from 2017 to 2018. The influencing factors were also determined, including the irrigation quantity, fertilizer application rate, and tillage mode. Among them, the conventional irrigation and fertilizer application were set as the control group in this case. The rotary and deep tillage modes were set at the same time. A total of 18 experimental treatments were carried out, each of which was arranged in the three experimental plots for repeat. Some parameters were measured, including the soil gas emission flux, crop water use efficiency, and crop yield. The test results show that: 1) There was a very significant level in the single factor effects of irrigation amount and fertilizer application rate on the yield and water use efficiency, as well as the effect of tillage mode on the yield, except for water use efficiency. There was no significant interaction between the three factors. Since the irrigation amount in a certain range increased the yield of the winter wheat, too much irrigation amount led to a significant decrease in the grain yield. The water use efficiency was higher than before when the irrigation amount was in the middle and low level. 2) There was the highest flux of N2O emission in summer during the growing period of winter wheat, while the lowest in spring and winter. Specifically, the N2O emission flux of soil showed several peaks, most of which occurred after irrigation during the growing period of summer corn. There was a positive correlation between the soil CO2 emission flux and soil surface temperature during the growing period of winter wheat. The peak of soil CO2 emission flux during the growing period of summer maize was concentrated in the stages from the seedling emergence to the jointing and from the tasseling to the silking. 3) There was a significant level in the interaction effects of irrigation water, fertilizer application, and tillage modes on the CO2-eq emission fluxes of winter wheat and summer maize. The mean N2O and CO2 emission fluxes were 261.57 mg/m² and 7 885.52 kg/hm², respectively, under the rotary tillage. In the deep tillage, the mean values of N2O and CO2 emission fluxes were 331.91 mg/m² and 9 313.69 kg/hm², respectively. The cumulative emission fluxes of N2O and CO2 under rotary tillage were 21.19% and 15.33% lower than those under deep tillage. 4) The low to medium level of irrigation and fertilizer application under the rotational tillage greatly contributed to the improved water utilization and crop yield, while reduced CO2-eq emissions. The CO2-eq emissions decreased by 3.4%, whereas, the water utilization increased by 8.16% under the low water and medium fertilizer rototill conditions. The CO2-eq emissions decreased by 1.9%, whereas, the water utilization increased by 19.9% under the medium water and low fertilizer rototill conditions. The CO2-eq emissions decreased by 13.8%, whereas, the water use efficiency increased by 12.24% under the low water and low fertilizer rototill conditions. The findings can provide a strong reference for the water saving and emission reduction of winter wheat and summer corn. [ABSTRACT FROM AUTHOR]

Mulberry leavesare rich in plant polyphenol and flavonoid. Amounts of hydroxyl and hydroxyl functional groups are distributed on the surface, which can be absorbed with heavy metal ions by complexation and electrostatical processes. However, there are commonly soluable tannic in organisms and it is not suitable to use organisms to remove Cd from waste water. In this study, mulberry leaves were used as the experimental materials and were boiled and modified with 1 mol/L H3PO4 to prepare an adsorbent for cadmium. Results show that the absorption effect of modified mulberry leaves to Cd(Ⅱ) is best when pH is 4.0. When the initial concentration of Cd is 150 mg/L,6 g/L modified mulberry leaves have absorption recovery of 96.58%. The adsorption process of modified mulberry leaves to Cd(Ⅱ) adheres to the pseudo-second order equation. The isothermal adsorption process of cadmium with modified mulberry leaves fits the Langmuir model well. Maximum absorption capacity of Cd(Ⅱ) on the chemically modified mulberry leaf absorbent is 30.58 mg/g, which is higher than that of a previous study. The modified mulberry leaves are easily available, which provides a new method for Cd removal from waste water. [ABSTRACT FROM AUTHOR]

Formulating non-dominated solution set effectively can speed up the solving process of the Pareto front, and can improve the quality and efficiency of multi-objective decision-making. Therefore, based on the definition and feature of the non-dominated solutions, the lemma of dominations relation transitivity, the theorems and lemma of non-dominated solution set construction are deduced. Depending upon the proposed theorems and lemmas, a novel non-dominated solution set construction method is first proposed. Then the frequency of the comparison and the number of iteration in the new method are counted, and a novel formula is put forward to calculate the deterministic value of computational complexity in the worst case. Finally, the correctness and completeness of the new method are proved in theory, and the structural features of the construction set at the maximum degree of complexity are given, what's more, the performance test of the new method is carried out through the ZDT1 ~ ZDT3 test functions. The results show that the new method is lower in computational complexity and faster in construction speed than the exclusions method and electoral law method. [ABSTRACT FROM AUTHOR]
