The tolerance to glyphosate of Zong 31 and weeds in the 3-leaf period indicated that it was belter to prevente and cure weeds when the glyphosate concentration was 1.2g/l,which was nearly the lethal concentration of Zong 31 in the 3-leaf period.

草甘膦在玉米三叶一心时对玉米和杂草的喷施效果表明，1.2g/l的浓度时对杂草的防治效果良好，对玉米接近致死浓度，所以确定筛选时期选择在玉米三叶一心时期，浓度为1.2g/l。

The effect of Zea mays and Bromus riparius on soil and water loss were studied,the experiment was conducted to plant crop and grass in runoff-plots on the 15 degree slope naturally,the bare slop is CK,then the runoff and soil erosion amount and the biological characteristics of corn and meadow bromes termly were measured,and difference of soil and water loss prevention effect on the slop land were determined.The results showed that soil and water loss became less after both corn and meadow brome planting.And the leaf area and the coverage of meadow brome higher than corn,which was benefit for less soil and water loss at the rain season early.Meanwhile,roots of corn and meadow brome mainly distributed in 0-10 cm soil layer,and the root biomass of meadow brome was 2.88 times than that of corn.

试验在自然降雨条件下，在15°坡地设置作物与牧草径流试验小区，以裸地为对照，在每次降雨之后用全深剖面采样器取样，测量其径流量和土壤侵蚀量，定期测定玉米和草地雀麦的生物学特性，研究玉米与草地雀麦生物学特性变化及其坡地水土流失防治效果的差异，探索植物种植对坡地水土流失的主要影响因素，结果表明：种植玉米与草地雀麦，对坡地水土流失均有一定防治作用，但是，与玉米相比，草地雀麦的叶面积指数和覆盖度可在雨季前达到较高水平，有利于早期坡地水土流失防治。

Using large sample DNA of capacity technology, the maize high lysine content of SSR mark analyse technological platform has been established in this paper. The main results are as follows: the five comparing research methods of drawing maize DNA mark have shown that the method of iso- sulphur cyanic acid guanidine drawing maize genome DNA has the superiority of using less medicine, operating sequence more simple , faster, and costs lower , steady and reliable quality of DNA, etc..Utilizing this method , one person can draw 300-400 DNA samples each workday.lt indicates that the method can be used in SSR marker of maize,.

本文从大样本容量的DNA快速提取技术入手，初步建立了玉米高赖氨酸含量的SSR分子标记分析技术平台，获得的主要结果如下：对五种玉米DNA提取方法的比较研究认为，异硫氰酸胍法提取玉米基因组DNA，具有使用药品少、操作步骤简单、快速、成本低、DNA质量稳定可靠等优点，利用该方法，每人每个工作日可以提取300～400个DNA样品，可以在玉米SSR标记分析中应用。

Study on the genetic characteristic of improved lines which can broad temperate maize genetic basis, found new heterotic patterns, resolve the back and force situation, overcome the obstacle of high and super- high yield breeding, provide the technique guarantee for the sustainable development of Chinese maize production.

对改良系进行遗传研究，拓宽温带玉米的遗传基础，构建新的杂种优势模式，这将解决我国玉米育种徘徊不前的局面，克服玉米高产超高产育种的障碍，为我国玉米生产的可持续发展提供技术保障。

There are vegetables and vegetables daily, Lycopus, melon leaves, Beijing cabbage, Chinese cabbage, rape, mustard, lettuce, celery, spinach, kale, water spinach, radish, Ma bitter vegetables, beans and even leaves, sweet potato leaves, pumpkin Miller, pumpkin flowers, pea sprouts can also dish.

玉米也有机玉米与糯玉米之别，机玉米用于熬粥，有时也煎成玉米饼。

Trends of overground physiological and biochemical indexs are almost the same—weak soil Naphthalin pollution stress stimulate them,strong pollution restrain stress them. In the first two weeks of seeding stage weak soil Naphthalin pollution stimulate root activity,but soil Naphthalin pollution stress restrain root activity from the second week till jointing stage, In corn grouting stage soil Naphthalin pollution stress stimulate root activity.

部分的生理生化指标都有促进作用，而高浓度的土壤萘污染胁迫对玉米地上部分的生理生化指标有抑制作用；苗期的前两周低浓度土壤萘污染胁迫对玉米的根系活力有促进作用，苗期第三周到拔节期土壤萘污染胁迫抑制玉米的根系活力，而到了用营养生长到以生殖生长为中心的灌浆期土壤萘污染对玉米的根系活力有促进作用。

Physiologicalmechanism of high yielding corn in the ravined valley was studied. Based on the results,the technical regime of ecologically adverse resistant and high yielding cultivation forthe corn in the ravined gully has been constructed. The major detailed techniques for theregime are ridging-ploughing in autumn and film-mulching during the thawing time inspring, adopting compact corn varieties with big ears and grains and adequately longgrowing stage, fertilizing adequately at seedtime and at jointing stage and irrigatingwith floodwater in the middle and late. The standardized techniques have also beenestablished.

&九五&期间，我们以充分发挥沟谷地的生态资源优势和育壮苗、攻大穗、增粒重的玉米高产规律为结合点，研究与明确了沟谷地高产玉米的生理机制，组建了以秋耕起垄顶凌覆膜保墒、选用紧凑型&三大&玉米品种、施足底肥重攻拔节肥、中后期洪淤补灌等四项技术为核心的沟谷地玉米生态抗逆高产栽培技术体系，制定了针对性强、技术准确、便于操作、简单易行的规范化技术。

本文综述了8个已应用于商业化育种的甜玉米胚乳突变基因的染色体位点、编码的产物及其表现型，介绍这8个甜玉米胚乳突变基因的分类、遗传效应及其互作效应，并提出其在我国甜玉米育种中的应用策略，旨在为甜玉米的深入研究和开发利用提供参考。

We have developed sweet mucilaginous mealie normal temperature preserving projects, we use biological enzyme method to produce sweet mucilaginous corn steep olquor pure crude drink, we produce health benefits yeast calcium, ferro, zincum, selenium, germanium etc.

开发了甜粘玉米穗常温保鲜项目；生物酶法生产甜粘玉米浆纯天然饮品；以玉米糖化液为原料生产益生酵母钙，铁，锌，硒，锗等营养冲剂，兼具了补充人体必需微量元素和益生菌两方面的特点，同时含有玉米糖浆丰富的营养，较比其他方式的微量元素补充剂具有更易吸收的特点。

There was an interaction between maize and intercrops in Cd uptake. Legumes absorbed smaller amount of Cd but significantly increased the Cd uptake by maize, while amaranth was in adverse. Rape had a higher level of Cd concentration in its shoot, but reduced the Cd in aboveground part of maize.

间作植物与玉米对Cd的吸收具有不同的交互作用特征，豆科作物在自身较少吸收Cd的条件下，显著提高了玉米对Cd的积累；籽粒苋在自身大量累积Cd的同时，一定程度上抑制了与其间作的玉米的Cd累积量；油菜地上部分吸收较多的Cd，但降低了玉米地上部分Cd含量。
