一、选地整地施肥选择疏松肥沃且有排灌条件的壤土或砂质壤土种植。每亩施土杂肥3000—4000公斤,复合肥10公斤,翻地深20—30cm,整平耙细,做成1.2M宽的平畦,以备播种和移栽。二、繁殖方法 8月上旬,采下成熟的种子后,室温浸种24小时,捞出稍凉,按每亩用种量2—3公斤,均匀撒于做好的畦内,复土2cm,出苗后适时浇水除草;翌年秋每株可形成3—5个地下茎,刨出整株,掰下长2cm以上的地下茎,做为繁殖材料,亦可结合收获选择地下茎有芽的一段切下,长约3cm,做为繁殖材料,在整好的畦内按行距25cm,株距8—10cm,深2cm栽种。若干旱,应先浇水造墒,待干湿合适时再栽种。春栽或 First, the selection of land preparation and fertilization Select loose and fertile conditions of irrigation and drainage of loam or sandy loam planting. Application of soil fertilizers per mu 3000-4000 kilograms, 10 kilograms of compound fertilizer, turn the ground 20-30cm deep, flat rake thin, made of 1.2M wide Pinggu, to prepare for sowing and transplanting. Second, breeding methods In early August, after the harvest of mature seeds, soaking for 24 hours at room temperature, remove a little cold, according to the amount of 2-3 kg per acre, evenly sprinkled in a good 畦, compound soil 2cm, emergence After the timely watering and weeding; the following autumn each plant can form 3-5 underground stems, planing the whole plant, breaking off more than 2cm long underground stems, as a breeding material, can also be combined with the harvested underground stems have a bud cut section, long About 3cm, as a breeding material, within the fine 畦 by row spacing 25cm, plant spacing 8-10cm, deep 2cm planted. Drought, watering should be made before planting moisture, wet and dry when appropriate and then planted. Spring planted or

戊聚糖是小麦籽粒中重要的组分之一,主要存在于细胞壁中,因其特殊功用而受到国内外广泛关注。目前国内外对戊聚糖结构、作用机理和性质等方面都有比较深入的认识,而生态因子和栽培因素对小麦籽粒戊聚糖含量及其合成的调控技术报道甚少。本研究选用不同类型的专用小麦,在不同生态点,不同栽培措施下(水分、肥料、播期、库源),研究了小麦籽粒戊聚糖含量及积累动态特征,以期为深化小麦籽粒戊聚糖形成机制研究和小麦调优栽培技术

本实验选用S06和S52两个黄瓜品系,以子叶和子叶节两种不同外植体作为转化受体,利用根癌农杆菌LBA4404介导进行遗传转化,同时对预培养时间、共培养时间和抗生素敏感程度三个影响
所获得转Bt+CpTI双价基因抗虫棉品系(简称双价抗虫棉),抗虫谱广,抗性强,单株结铃性强,但铃重较轻、衣分偏低、马克隆值偏高、生长势弱、易早衰。常规棉品种,适应性强,产量高和纤维品质优。本文以转Bt+CpTI双价基因抗虫棉品系,以及与常规品种配制的抗虫杂交种为材料,在转基因抗虫棉的棉铃虫抗性时空表达特性、对棉铃虫幼虫生长发育和营养效应的影响、抗虫蛋白的表达与氮代谢关系、抗虫性遗传规律、抗虫基因对
