旨在分析干旱区水氮耦合效应对膜下滴灌棉花的生长机制.采用灌溉定额和施氮量二因素完全随机试验,研究水氮耦合效应对棉花生长性状及产量的影响.结果表明:灌溉定额为3300 m3/hm2时棉花苗期一蕾期天数增加,开花期-吐絮期天数缩短,地上部干物质积累量较低.灌溉定额为4500 m3/hm2时随着施氮量的增加,棉花株高、地上部干物质积累量增加,但产量呈先增加后下降的趋势.不同的灌溉定额下,施氮量为150 kg/hm2时,棉花蕾期-盛铃期天数最短,蕾铃脱落率较高,施氮量增加至375 kg/hm2时,棉花株高、地上部干物质积累量较高,但叶面积指数、单株有效铃数和单铃重呈下降趋势.灌溉定额为3900 m3/hm2施氮量为300 kg/hm2时,棉花蕾期-盛铃期天数延长,优化了产量构成因素,产量达到最高为6992.33 kg/hm2.

综合技能教育与人文素质教育都是高职教育人才培养的重要组成部分,实施综合技能与人文素质教育融合是高职教育发展的历史必然和现实需要。有利于培养全面发展的高技能、应用型人才,有利于构建创新人才培养体系,有利于受教育者可持续发展.现有高职教育体制已不适应学生人文素质教育与综合技能教育的融合,需通过整合学院教育机制、创新专业课程体系、改革课程教学方法、建设"双师型"教师队伍、占领校园文化与第二课堂阵地等途径来实现。

;高职人才培养实施综合技能实训课程与资格证书融合,有利于知识整合和技能综合,可促进教学与职业就业岗位的"零距离对接",带动对教材、教学设各、实训场地的建设,带动专业课程整体改革,将职业标准融入"课程标准",实现高职职业技能培养与职业资格考试同步.教学中可以通过制定课程目标、选择综合技能实训模式、构建教学大纲和选择教学方法、确定组织形式、准备必要的实训条件、确定考核评价方法、制订综合实训课程与职业资格证书融合方案等措施来实现二者融合,并在两年来的教学实践中取得了显著效果.

<正>人才培养模式是为培养目标服务的,不同的教育类型、办学层次、办学形式,其培养目标不同,人才培养模式也不同。一种人才培养模式是否能够很好地实现培养目标、是否能够满足学生就业的需求是判断其应用是否科学的依据。自二次世界大战之后,各发达国家都大量培养高等职业技术人才,在培养

教材是实现教育目的的主要载体,而精品教材的建设更是体现职业教育特色的关键。精品教材建设应在分析现有教材现状及存在问题的基础上,理清基本思路,根据精品教材建设原则与要求,顺应职业教育教材发展趋势,建立和完善教材建设体制与运行机制。

The correlation and the diameter analysis to the main agronomic characters of the eight weak vernal wheat varieties which were demonstrated on the 2004-2005 national wheat variety exhibition was done, and the results to indicate the agronomic characters and the output relativity are in turn: number of ear in hm2 (0.8034), seed number of each ear (0.5492), weight of a thousand seeds(-0.4146), high(0.3366), ear of long(0.0639) and each ear of spike let number. The importance of the direct factors to the output are in turn: weight of a thousand seeds (1.5139), each ear of number of seeds (1.0816), ear of number in hm2 (1.0254), high (0.4358), each ear of spike let number (0.2968) and ear of long (-0.0274). It indicates that the agronomic characters have the obvious restricted relations. The strategy of the high production of the vernal wheat in Henan province and the technology of the high production cultivation are proposed.

The comparative study on the two methods for determining the decomposing and retention rate of the organic material in fluvo-agvic soil in Henan province was carried out.The result showed that it conformed to the actual condition of the field to determine the decomposing and retention rate of the organic material with the method of nylon bag-potassium dichromate,so it's suggested that the relative study being performed with the method to replace the method of sand filtration tube-potassium dichromate.The humification cofficient of the wheat straw determined with the nylon bag method was 12.25%.

The experiment was conducted in sandy soil of Eastern Henan Province to investigate the effects of the allotment of P on different crops in the system of winter wheat intercropping with peanut.The results showed that soil available P represented the characteristics of high in winter and low in summer in the rotation.The minimum occurred in the period of winter wheat sprout to the start to grow while the maxmum occured in that of peanut seedling to harvest,and this trend did not change when P fertilizer was applied.The usage of P could noticeably increase the N uptake,and the uptake efficiency of N by winter wheat and peanut increased by 7-20% and 12-24%,respectively.It was noticed that P fertilizer should be used more to winter wheat and less to peanut in the rotation.More carefulness should be paid to once application of large amount of P when soil available P was low and lack of P fertilizer.

We studied the effect of the compound microbiological preparation on the yield and quality of the replanted strawberry.The result showed that the compound microbiological preparation reduced the verticillium wilt in nonsterilized soil by 76.9%-84.6%.Whether the soil was sterilized or not,the compound microbiological preparation could always increase the photosynthetic rate of strawberry leaves and the content of chlorphyll,promote the growth of the strawberry plant,increase the content of vitamin C and the soluble sugar in strawberry fruits,improve the quality and flavor of the fruits,and boost the yield by 14.21%-16.20%.At the same time it could improve the physical and chemical characteristics of soil and increase the productivity of soil as well.

This paper used grey system evaluation method to analyze the effect of 4 different kinds of leaf fertilizer on hybrid cotton,and finded out that humic acid leaf fertilizer had the best effect,the requlative pharmaceutical leaf fertilizer was the worst,while amino acid leaf fertilizer and microelement leaf fertilizer were somewhere between.

利用沃尔特钾基磷铵、奥诺嘉尔吉嘉安磷2种俄罗斯复合肥在芹菜上进行了试验.结果表明,同国产三元复合肥相比,2种俄罗斯复合肥料在促进芹菜生长、增加产量、提高品质方面效果更好.可增产6.05%～7.30%;叶柄维生素C含量增加4～5 μg/g、叶片维生素C含量增加9～11 μg/g;硝酸盐含量降低4.10～4.27 mg/kg;施肥净收入增加2 478.6～2 988.9元/hm2.

农村职业教育是我国"十五"时期发展的重点,也是职业教育发展的新的增长点,农村职业技术教育在农村发展、社会稳定、农民生活质量提高等方面都有相当重要的意义和作用.根据目前我国农村劳动力的受教育程度现状、国家"三农"政策导向、社会经济发展的需求,农村职业教育必须实行平衡化发展的战略.

为了解不同类型叶面肥料在河南省棉花生产上施用效果.于2003年选择了4种不同类型叶面肥料进行棉花肥效试验,以评价其在生产上的使用效果,以期为棉花生产提供依据.

Abstrcat The experiment results showed that compound microbiological preparation could promote the mycelial growth of Pleurotus ostreatus, reduce the contamination rate,improve the biological efficiency and improve the quality of fruitbody greatly. The contamination rate could be reduced by 31.7% and the biological efficiency could be improved by 79.6% by adding 1.0% compound microbiological preparation to raw compost.And the contamination rate could be reduced by 12.5% and biological efficiency could be improved by 42.4% if 0.5% compound microbiological preparation was added to the fermented compost.

应用灰色系统评价方法对4种不同类型的叶面肥在杂交棉花上应用效果进行分析,从而得出在对综合性状的影响等权与加权关联度中,腐殖酸叶面肥关联度最大,含调节剂叶面肥关联度最小,氨基酸叶面肥和微量元素叶面肥效果居中.4种叶面肥关联度都高于清水对照.
