Effect of Cold Plasma Treatment on Seed Germination and Growth of Wheat简

This study investigated the effect of cold helium plasma treatment on seed germina- tion, growth and yield of wheat. The effects of different power of cold plasma on the germination of treated wheat seeds were studied. We found that the treatment of 80 W could significantly improve seed germination potential （6.0%） and germination rate （6.7%） compared to the control group. Field experiments were carried out for wheat seeds treated with 80 W cold plasma. Com- pared with the control, plant height （20.3%）, root length （9.0%） and fresh weight （21.8%） were improved significantly at seedling stage. At booting stage, plant height, root length, fresh weight, stem diameter, leaf area and leaf thickness of the treated plant were respectively increased by 21.8%, 11.0%, 7.0%, 9.0%, 13.0% and 25.5%. At the same time, the chlorophyll content （9.8%）, nitrogen （10.0%） and moisture content （10.0%） were higher than those of the control, indicating that cold plasma treatment could promote the growth of wheat. The yield of treated wheat was 7.55 t-ha-1, 5.89% more than that of the control. Therefore, our results show that cold plasma has important application prospects for increasing wheat yield.     

水田旱整机插稻栽培技术研究

本研究通过机械配套组合,形成施肥、旋耕、整平、筑埂和建立丰产沟,完成土壤旱地整平后上水栽秧的水田旱整技术,改变多年来水稻上水整田的措施。加强耕层土壤疏松透气,促进水稻根系发育和植株生长。根据试验调查结果:水稻生长中期单茎根数、地上部干物重和根干重均高于常规水整;旱整水稻有效穗、实粒数和千粒重分别比水整高30.0万/hm2、10.1粒和1.1 g,并形成从水浆管理到化除等一系列高产栽培技术。同时,缩短从耕地到栽插的时间2~3 d,增加水稻适期栽插面积,实现水稻大面积平衡增产。     

锌肥作底肥施用对水稻产量的影响

为了解锌元素在水稻主产区的应用效果,掌握适宜的微量元素施用量,2013年进行了水稻锌肥用量试验。1材料和方法1.1供试土壤、品种及肥料试验于2013年在江苏省农垦农业发展股份有限公司新洋分公司农科所试验田进行。试验地块选择当地中、低等肥力土壤、没有施用过含锌肥料的缺锌土壤,设在农科所试验田3号,土壤为壤性潮盐土,肥力中等,土壤有机质含量22.0 g/kg,全氮含量1.45 g/kg,碱解氮含量118 mg/kg,
