Direct seeding of rice has become a main planting method due to the low labor input and high economic benefit in South *** direct seeding(DDS)has been widely used for single-season rice planting ***,few studies have examined the performance of early-season indica rice under mechanical dry direct seeding.A two-year field experiment was conducted with two indica rice cultivars(i.e.,Zhongjiazao 17 and Zhuliangyou 819)to study lodging characteristics and grain yield formation under DDS,flooded direct seeding(FDS)and wet direct seeding(WDS)*** results showed that the annual grain yield in DDS was higher by 14.42–26.34%for cultivar ZLY819 and 6.64–24.58%for cultivar ZJZ17 than in WDS and FDS,respectively,and these increases were mainly attributed to the improvement of the *** DDS pattern significantly increased the seedling emergence rate of early indica rice cultivars,and increased total dry weight and crop growth ***,shorter basal internodes,better stem diameter and stem wall thickness and lower lodging index were found in DDS in contrast to FDS and *** particular,DDS improved the stem lodging *** results suggested that the appropriate direct seeding method was beneficial for improving the grain yield and lodging resistance of early indica rice.

Glass appears to be an ordinary material with wide applications in daily life and industry; however, its formation mechanism, phase transition and microscopic structure remain mysterious. It is accepted to be an amorphous solid exhibiting glass transition, with short-range(20?A)disorder structures [1]. Experimental determination of the structure of glass is crucial to understand its dynamic and physical properties.‘What is the nature of glass?’ is one of the most fundamental and challenging scientific questions [1].

There is great controversy regarding the origin and source of natural gas in the Lower Triassic Feix-ianguan Formation in the Eastern Sichuan *** seriously restricts the study of natural gas dy-namics in the Feixianguan Formation and thus hampers natural gas exploration in the region,so further study is urgently *** experimental tests of natural gas composition,stable isotopes,and noble gas isotopes with gas chromatography(GC)and mass spectrometry(MS)studies of source rock and reservoir asphalt saturated hydrocarbons,the natural gas geochemical characteristics,the genetic identification and a gas-source comparison of the Feixianguan Formation were ***,con-strained by the thermal history,the histories of gas generation and expulsion were restored by basin simulation ***,a gas accumulation model was established for the Feixianguan *** results showed that(1)the H_(2)S-rich and H2S-poor gas reservoirs of the Feixianguan Formation are distributed on the east and west sides of the Kaijiang-Liangping trough in the Eastern Sichuan Basin,*** carbon and hydrogen isotope compositions of the natural gas in the gas reservoirs are generally heavy and have typical characteristics of high-maturity dry gas reservoirs.(2)The natural gas of the Feixianguan Formation is organic thermogenic gas,which is mainly oil-type gas generated by the secondary cracking of crude *** gas-generating parent material is mainly type II kerogen.(3)The natural gas of the Feixianguan Formation in the Eastern Sichuan Basin was mainly generated by argil-laceous source rocks of the Upper Permian Longtan Formation.(4)Natural gas accumulation occurred as follows:the paleo-structure heights were filled with crude oil in the Early Jurassic,and paleo-oil res-ervoirs were formed in the Feixianguan Formation;during the Middle-Late Jurassic,the paleo-oil res-ervoirs were cracked when the reservoir temperatures rose above 160 C,and paleo-gas reservoi

This work was to determine which concentration of a mixture of fresh Humulus scandens （HS） and fresh alfalfa could be included in diets for rabbits. The fresh forage of three experimental diets is composed of 100% alfalfa, 50% alfalfa ＋ 50% HS, 100% HS, respectively. 30 rabbits [（1.42 ± 0.056） kg] were used to determine nutrient digestibility. A feeding trial was carried out using 90 weaning rabbits [35 d of age; （512±6.5） g]. Increasing content of HS in the diet did not affect digestibility of DM （dry matter）, CF （crude fiber）, CP （crude protein）, GE （gross energy）, and EE （ether extract）. But diarrhea decreased markedly （P〈0.01） compared with the diets that had no HS. ADF1 （average daily feed intake） increased by 4.3% （P 〈 0.05） and 3.6% （P 〈 0.05） when rabbits fed the diet with 100% HS of fresh forage compared with the diets containing 0 and 50% HS, respectively. Feed efficiency improved significantly （P 〈 0.05） by 2.07 and 5.30% when rabbits fed 0 and 50% HS of fresh forage, respectively, compared with 100% HS. There was no effect on ADG （average daily weight gain）. In conclusion, the mixture （50：50） of HS and alfalfa constitutes an alternative source of fiber for fattening rabbits and prevents diarrhea effectively.

We analyze the existence and stability of two kinds of self-trapped spatially localized gap modes,gap solitons and truncated nonlinear Bloch waves,in one-and two-dimensional optical or matter-wave media with self-focusing nonlinearity,supported by a combination of linear and nonlinear periodic lattice *** former is found to be stable once placed inside a single well of the nonlinear lattice,it is unstable *** to the case with constant self-focusing nonlinearity,where the latter solution is always unstable,here,we demonstrate that it nevertheless can be stabilized by the nonlinear lattice since the model under consideration combines the unique properties of both the linear and nonlinear *** practical possibilities for experimental realization of the predicted solutions are also discussed.
