活体微生物农药批量生产 总被引：1，自引：0，他引：1
正当中国茶叶出口面临“绿色”壁垒频频冲击时，一种以昆虫病毒为主的“活体微生物农药”日前被国家农业部正式批准实现批量生产，这标志着我国茶叶出口农药残留超标难题将迎刃而解。这种最新研制的“活体微生物农药”被命名为“武大绿洲茶园”，是国家计委批准的“国家高技术产业化示范工程项目”中一项生物高新技术成果。它是按照联合国粮农组织（FAO）和世界卫生组织（WHO）共同创导使用的最有毒力和最安全的昆虫杆状病毒与其它微生物复合而成。农残超标已成为中国茶叶出口的“瓶颈”。由武汉大学生命科学学院昆虫病毒研究所和湖北武… 相似文献

近几年,由于畜产品中兽药残留超标,严重影响了我国畜产品的出口.例如1990年出口日本的1万t肉鸡,由于检测出抗球虫药氯羟吡啶的残留超标,要求我国政府销毁所有产品,给我国造成了很大的经济损失.同年,出口到德国的蜂蜜由于农药“杀虫脒“残留超标而被退货.…… 相似文献

通过对甘肃省近3年出口苹果的农药残留抽检结果进行安全性评估,对我国和主要贸易国的农药残留要求进行了梳理。结果表明,甘肃省苹果的农药残留均在安全范围内,符合出口贸易对农药残留的要求;我国与主要贸易国之间对农药残留限量的要求还存在很大的空白,需要及时进行标准更新。 相似文献

芋头是烟台市特产蔬菜，其球茎口感细腻，品质极佳，深受消费者欢迎，年出口8万t以上，是重要的出口创汇蔬菜。近年来，随着种植面积和出口量的增加，外商对我国生产芋仔的品质、农药残留等方面的要求也越来越高，新的加工出口形势要求我们改善芋仔品质，降低农药残留，打造农产品绿色品牌。 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
