In the big peanut regional tests in north China in 2011-2012, Shanghua No.6 had the average yield of pod and seed respectively of 4 695.30 kg/hm^2 and 3 514.73 kg/hm^2;in the production test in 2013, its average yield of pod and seed were 4 531.0 5kg/hm^2 and 3 312.15 kg/hm^2. Its crude fat content was 50.46-53.46%, oleic acid content was 50.9-51.7%, and oil oleic acid/linoleic acid value was 1.69-1.76. The variety was high-resistant to brown spot and focal spot, susceptible to black spot,resistant to net blotch and stem rot. Its 100-pod weight was 256.2 g, 100-seed weight 111.2 g, and shelling percentage was 74.75%. The variety was certificated by National Crop Variety Approval Committee in 2014（identification number：2014010）, which was suitable for planting in Shandong, Henan, Hebei, Liaoning,Beijing, north of Huaihe River in Jiangsu and Anhui provinces.展开更多

During flowering stage, leaf cutting, application of ＂920＂ and pollination were conducted; after pollination, bentazon with a certain concentration was sprayed to kill the male parent; and the hybrid rice was harvested mechanically. Before storage, color separation was performed to remove little remaining male parent, thereby achieving whole-process mechanization of hybrid rice seed production. This study introduced mechanized seed production of Xinhunyou No. 6 through mixed- seeding from the aspects including mechanical direct seeding, seeding raising fol- lowed by transplanting and mechanical planting.展开更多

Lymphadenectomy of lymph nodes No. 5 and No. 6 is the major difference between total and proximal gastrectomy. We elucidated the appropriate surgical procedure for PGC by investigating the pathological characteristics and prognostic significance of lymph nodes No. 5 and No. 6.Methods: In total, 333 PGC patients who underwent total gastrectomy were enrolled in this study. We investigated their clinicopathological characteristics and the metastatic patterns of the lymph nodes. Patients with metastasis in lymph nodes No. 5 and No. 6 were combined into one group and we compared the difference in survival between those with and without metastasis in lymph nodes No. 5, 6(lymph nodes No. 5 and No. 6 in any group of metastasis) for different subgroups.Results: The metastatic rates for lymph nodes No. 5 and No. 6 in PGC were 9.91% and 16.11%, respectively.The metastatic rate for both lymph nodes No. 5, 6 was 20.42%. Multivariate analysis showed that positive metastasis in lymph node No. 4, depth of invasion, and tumor size were independently correlated with the presence of metastasis in lymph nodes No. 5, 6.Conclusions: When lymph node No. 4 is positive(intraoperative pathology) or tumor size ≥5 cm or T4 stage,lymphadenectomy should be performed for lymph nodes No. 5 and No. 6, and total gastrectomy is recommended.展开更多

The authors selected this deposit and used the multivariate statistical analysis to study the types of association of main ore-forming elements at different temperatures and pressures and their distribution in the deposit. On that basis combined with the structural analysis of the deposit, the recto-geochemical features of No.6 East tin deposit have been revealed and the direction and channel of migration of the ore solutions in faults and the deposit have been deduced. This research can appropriately elucidate the control of faults on the migration of ore solutions and the sites where ore solutions are dispersed and accumulated, thus providing the theoretical basis for the prediction of hydrothermal deposits in question.展开更多
