《中华人民共和国种子法》(以一简称《种子法》)及其配套的法规、规章实施以来,各级农业行政主管部门认真贯彻执行并规范种子市场的经济秩序,种子质量监督检查工作取得了显著成就。但是,随着种子市场的放开和经营主体增多,使品种混杂,未审先推,不规范经营行为,制售劣质种子坑害农民的事件时有发生。农民一旦受到损失仅仅得到很少的赔偿。极少数有法律意识的农民往往要经过艰苦的法律诉讼才能得到《种子法》、《中华人民共和国农业技术推广法》所规定的应有的补偿,始终处于弱势的农民,其合法利益很难得到保障,严重损害了农民的利益。为了维护企业和农民的合法权益,使种子市场健康有序发展,必须做好以下几方面的工作。 相似文献

“未审先推”是指《中华人民共和国种子法》(以下简称《种子法》)规定应当审定的农作物品种未经审定通过而先行宣传、推广的行为。这种现象目前仍具有一定的普遍性 ,且禁而不止。本文分析了未审先推现象的成因 ,并提出了加以控制的建议及措施 ,供参考。1 现象及形式目前 ,许多种子经营单位较普遍地存在着公开或隐蔽地销售未审品种的现象 ,自称是“农民喜欢种植 ,这也叫为农民服务”。有些农业技术人员认为 ,搞新技术推广和新品种示范开发 ,审定后的品种就不新了。有些基层领导干部到外地参观学习 ,看到某个品种表现好 ,回来后即在某些会议… 相似文献

《中华人民共和国种子法》(以下简称《种子法》)实施后,我省种子行业发生了巨大变化,一是绝大多数县(市)级国有种子公司已退出区域性封闭市场,市场经营主体多元化格局已经形成,种子市场空前活跃;二是主要农作物新品种更新速度加快;三是各地在探索种子管理制度和执法队伍建设上取得了一些实效。但应当看到:在一些地方,种子市场还存在一些混乱现象,品种未审先推、一品多名等还未能得到根本遏制;假、劣种子坑农的事件还时有发生等,极大地破坏了市场公平竞争秩序,直接影响和威胁农业生产安全和农民利益。[第一段] 相似文献

"未审先推",顾名思义是指经营推广应该审定而未经审定的农作物新品种种子的行为。《中华人民共和国种子法》(以下简称《种子法》)颁布实施10年来,我国种子市场呈现出空前的繁荣景象,市场供求也由卖方市场完全转型为买方市场,在某些玉米主产区,甚至出现了百余个玉米品种同时上市销售的壮观场面。 相似文献

Oil and protein crops are of growing importance in cropping systems. This study was carried out to compare oil crops of linseed, rapeseed, sunflower and protein crops of faba bean and white lupin for grain production, residual plant dry matter and nitrogen. Two field experiments with either oil or protein crops were conducted in 1993 and 1994, respectively. Total dry matter production, grain yield, residues, N concentrations and mineral N in the soil were measured. Dry matter production and distribution as well as N uptake and residues varied greatly among species and between years. In 1993, oil crops gave up to 3 t ha−1 grain and 16 t ha−1 residues with sunflower, while in 1994 up to 5 and 11 t ha−1, respectively, were recorded with winter rape. Protein crops showed an opposite reaction in years. Nitrogen uptake and residual N amounts were correlated with dry matter production. Plant residues of oil crops contained 20–140 kg N ha−1; those of protein crops up to 80 kg N ha−1. Despite the variation of residual plant N the variability of mineral N in the soil at harvest was hardly influenced by crops and amounted to only 20–50 kg NO−3-N ha−1. 相似文献

我国蔬菜产业和科学技术的发展与展望 总被引:1,自引:0,他引:1
1 我国蔬菜产业的发展现状蔬菜是人们日常生活中不可缺少的副食品,也是我国目前种植业中最具活力的经济作物。改革开放以来,随着市场经济的发展,农产品产销体制的不断改革和完善,特别是1988年实施“菜篮子工程”以来,蔬菜产业得到了蓬勃发展。1.1 播种面积1987~1999年,全国蔬菜播种面积由533.3万hm2,发展到1333.3万hm2,增长139.5%。1.2 总产量1987~1999年,全国蔬菜总产量由1.55亿t增加到4.05亿t,增长161.3%,使年人均鲜菜占有量达到330.7kg(世界各国人均105kg…… 相似文献

以Y05-222A和Y06-136R杂交得到的135株F2群体为研究材料,测定过氧化物酶(POD)、超氧化物歧化酶(SOD)、脯氨酸(Pro)、过氧化氢酶(CAT)、可溶性蛋白和丙二醛(MDA)等6个生理指标,并进行方差分析、相关性分析和通径分析,对F2群体进行偏度及峰度分析。结果显示,以上6个生理指标在F2群体中P>0.05,分布频率符合正态分布,同时存在双向超亲分离现象;相关性分析和通径分析显示,这些指标与抗盐碱系数均呈极显著相关(正相关或负相关),且相关系数与总间接通径系数方向一致。POD活性的直接通径系数为0.5003,可见POD直接影响抗盐碱性;CAT活性和Pro含量的直接通径系数分别为-0.1317和-0.0384,间接影响抗盐碱性;SOD活性、MDA及可溶性蛋白含量直接或间接影响抗盐碱性。POD、SOD、Pro、CAT、可溶性蛋白和MDA各生理指标的抗盐碱作用表现为POD>CAT>Pro>可溶性蛋白>MDA>SOD。叶片数、株高、茎粗和盘径与抗盐碱系数呈极显著正相关,其相关性表现为叶片数>盘径>株高>茎粗。以上结果可为研究油用向日葵抗盐碱性提供一定的理论基础。 相似文献

Acidity and sweetness in apple and pear 总被引:2,自引:0,他引:2
Summary Sweetness and acidity in apple and pear inherit independently and can be organoleptically evaluated separately, but less accurately in pear than in apple. For breeding purposes an analysis of fruits for acidity and sweetness with pH indicator paper and a hand refractometer is to be prefered to the organoleptic method.In apple, the acidity-decreasing with time-of the unripe fruit was already strongly indicative of that of the eating-ripe fruit; sugar-increasing with time-not before the fruit was picking ripe. Sugar content in apple and pear, and the pH in pear, appeared to be normally distributed; the pH in apple showed a segregation into an acid and a low-acid group, which occurred in both the unripe and ripe stage. The segregation ratio between these groups was found to be highly variable. On the whole, the mean acidity and sugar content of apple and pear progenies is significantly determined by that of the parents. Most of the observations made did not support the theory that low acidity in apple is determined by one recessive gene. The relationship between the pH of leaf juice and fruit juice in apple may offer a possibility for pre-selection. 相似文献
