A field study was conducted to evaluate the effect of organic mulches and tillage practices on growth, yield of cluster bean and soil physical properties. Experiment was comprised of two factors: A (Tillage), b (Mulches). Factor A was assigned to main plot and consisted of two treatments (Minimum tillage and Conventional tillage). Factor b was assigned to sub plot and consisted of four treatments (no mulch, wheat straw mulch, grass clipping mulch and saw dust mulch). The mulching materials were partially incorporated in the field after germination of crop. The experiment was laid out in Randomized Complete block Design (RCbD) with split plot arrangement having three replications. Control treatment was kept for comparison. All other agronomic practices were kept standardized and consistent for all the treatments. Data regarding growth and yield components were collected and analyzed statistically by fisher analysis of variance and treatment significance was measured by significant difference test at 5% probability level. The factors, tillage and mulches significantly affected growth, yield, yield parameters and soil physical properties. Maximum plant population (31.7 m2), plant height (159 cm), branches per plant (18.9), cluster per plant (15.88), grains per pod (7.3), 1000-grain weight (34.6 g), grain yield (1.9 t•ha-1), biological yield (9.91 t•ha-1) and harvest index (19.15) was recorded in conventional tillage comparative to minimum tillage. Mulches also affected grain yield, and maximum grain yield was recorded in wheat straw mulch (1.88 t•ha-1) followed by grass clipping mulch (1.81 t•ha-1) and saw dust mulch (1.76 t•ha-1) while minimum grain yield was recorded in control without mulch application (1.67 t•ha-1). Tillage and mulches interactively affect pH, soil organic matter contents, electrical conductivity and soil bulk density. Mulches and minimum till

Genes and Transcriptional Factors in Chili Plant with Aspect to Metabolism and Resistance against Virus, bacteria and Fungi： A Review

Journal of Agricultural Science and Technology(b) 2014年第7期4卷 509-517页

These days, there is a lot of discussion about genetically modified plants. There are different schools of thoughts in public, and some people adjusted while others are reluctant to accept genetically modified organism foods. Many vegetables are transformed and are used in daily life. Chili is one of those which is genetically modified and used in our food. Race specific genes can be used more efficiently for disease resistance and improving metabolic pathways. Different genes and transcriptional factors are available in Capsicum for this purpose. We can optimize and use the better expressed genes while engineering the chili plants, Genetic modifications causing significant changes are related with metabolism, which cause disease resistance.

单翼迷宫式滴灌带产品新国家标准中增加了氧化诱导时间(OIT),这对产品的抗热氧老化性能提出了要求。本文从滴灌带配方出发,讨论了产品原料与其OIT的料效关系,结果表明,防老化母料的加入比例对滴灌带的OIT影响最大,增加其比例可增大滴灌带的OIT;高密度聚乙烯(PE-HD)的加入比例对滴灌带的OIT影响大于线性低密度聚乙烯(PE-LLD)和低密度聚乙烯(PE-LD)的加入比例,增加PE-HD比例、减小PE-LLD和PE-LD比例可增大滴灌带的OIT;PE-LD的加入比例对滴灌带OIT的影响最小,在配方设计时应综合使用比例合理的PE-HD、PE-LLD、PE-LD以满足滴灌带良好的加工和其他性能要求;防老化母料中稳定剂比例不应随成本而减少,稳定剂比例增大时,滴灌带的OIT增大;通过对滴灌带的熔体质量流动速率(MFR)、炭黑含量及OIT指标测试,得出滴灌带MFR和炭黑含量与其OIT无明显的相互变化关系。

分别对滴灌带进行人工加速紫外老化和50℃热老化试验,研究了两种老化后氧化诱导时间(OIT)、熔融温度(T_(m))、拉伸强度(σ_(m))、拉伸断裂应变(ε_(m))、熔体质量流动速率(MFR)和炭黑含量(c)指标的变化,以及50℃热老化后流量均匀性、爆破压力、耐水压、耐拉拔和抗泥沙堵塞水力学使用性能变化或符合国标情况。结果表明,滴灌带人工加速紫外老化后的性能指标变化幅度明显大于50℃热老化的,尤其是OIT;在老化624 h后,人工加速紫外老化的OIT下降速率是50℃热老化的4.25倍。人工加速紫外老化的σ_(m)、ε_(m)、c、T_(m)和MFR下降速率分别是50℃热老化的1.24、1.17、1.11、1.02和1.01倍;滴灌带在人工加速紫外老化后,OIT、σ_(m)、ε_(m)和c的指标保持率变化相对较大;在50℃热老化后OIT保持率变化相对较大,水力学使用性能受50℃热老化影响较小,且在老化过程及624 h后均符合国标要求;对国标OIT不小于5_(m)in的要求而言,当保持率为21%时,σ_(m)保持率达到失效程度;因此,使用过程中滴灌带的OIT应不小于1.05_(m)in,否则可能失效。
