油菜根肿病的发生及防治

近日，笔者在广汉市等地了解到．今年油菜生产中，根肿病发生面积相当大，危害较重．一些地方甚至无苗移栽，导致改种小麦。在川西平原，一些地方连年种植油菜，使土壤积累了相当数量的病原菌．加上免耕栽培和近期雨水鞍多、田间湿度大等原因，非常有利于根肿病的发生和流行。现将油菜根肿病的防治方法介绍如下：

12种蔬菜干制技术

1．白菜干。选择叶色深绿、质地脆硬的白菜20千克，去掉老叶、老帮及菜根。切块后洗净。将清水煮沸，放入1。0克小苏打，稀释成0．5％的苏打水。将白菜投入锅中热烫1～2分钟，捞出，放入流动冷水中冷却。将白菜放入0-2％的冷小苏打水中稍泡，捞出后沥水，摊开，送进烘房烘制。烘温前期75～80℃，8小时后出烘房，包装。     

曰光温室连作障碍对策

l、1上壤传染性病虫害的积累。一些常见的病虫害如番茄青枯病、茄子黄萎病、黄瓜枯萎病、韭菜根蛆、多种蔬菜的根结线虫病以及果树腐烂病等，引起的主要原因是日光温室长期适宜的温湿度环境以及连作栽培条件下，由同种或同类作物根系分泌物和植株残茬腐解物给某种病原菌或虫卵提供了适宜的环境、寄主和丰富的营养，     

东北地区温室韭菜病虫害的诊断与防治

<正>韭菜一直以来深受广大百姓的喜爱,是现在家庭不可缺少的一种蔬菜。由于东北地区冬长夏短,要想吃上鲜嫩的韭菜就需要在温室里种植。但温室韭菜病虫害较为严重,成为当下农民种植韭菜的一大障碍。为了让农民减少温室韭菜的病虫害的困扰,下面就常见的病虫害的诊断与防治做以介绍。1.韭菜枯萎病1.1发病初期外叶的叶尖开始变成茶褐色,然后叶片渐渐枯死,中部叶子变白,这是因为温室温度较高而引起的叶烧病,也是生理障碍引起的叶腐病。     

技术遇难题 专家来帮忙

芹菜的心腐病是一种生理性病害，主要发病症状是芹菜外叶深绿，心叶干黄、腐烂。发病原因：（1）土壤中钙的含量缺乏；（2）土壤中硼的含量缺乏，造成芹菜根吸收钙困难；（3）土壤中盐类浓度过大，造成钙的吸收困难；（4）在干燥情况下氮肥用量过多造成根吸收硼困难，导致钙的吸收不足。     

川西坝子的“九斗碗”

九斗碗以蒸菜的“九大菜”而得名，即软炸蒸肉、清蒸排骨、粉蒸牛肉、蒸甲鱼、蒸浑鸡、蒸浑鸭、蒸肘子、夹沙肉、咸烧白。     

大白菜深加工技术

一、酸白菜。将白菜洗净，切去菜根，削除老帮，将l公斤以上的大棵菜纵切成两瓣或四瓣。将菜用开水烫1分钟，捞出后放入凉开水中冷却。然后取出并层层交错地排列在腌缸内，压以重石，灌入清水，使水淹没原料约l厘米。为促进发酵，可加少量米汤。腌制时间随外界温度高低不同，温度高腌制时间缩短，直到缸内有较浓酸味时即成。

Identification of Zinc Deficiency-Responsive MicroRNAs in Brassica juncea Roots by Small RNA Sequencing

The importance of zinc （Zn） as a micronutrient essential for plant growth and development is becoming increasingly apparent. Much of the world’s soil is Zn-deficient, and soil-based Zn deficiency is often accompanied by Zn deficiency in human populations. MicroRNAs （miRNAs） play important roles in the regulation of plant gene expression at the level of translation. Many miRNAs involved in the modulation of heavy metal toxicity responses in plants have been identiifed;however, the role of miRNAs in the plant Zn deifciency response is almost completely unknown. Using high-throughput Solexa sequencing, we identiifed several miRNAs that respond to Zn deifciency in Brassica juncea roots. At least 21 conserved candidate miRNA families, and 101 individual members within those families, were identiifed in both the control and the Zn-deifcient B. juncea roots. Among this, 15 miRNAs from 9 miRNA families were differentially expressed in the control and Zn-deifcient plants. Of the 15 differentially expressed miRNAs, 13 were up-regulated in the Zn-deifcient B. juncea roots, and only two, miR399b and miR845a, were down-regulated. Bioinformatics analysis indicated that these miRNAs were involved in modulating phytohormone response, plant growth and development, and abiotic stress responses in B. juncea roots. These data help to lay the foundation for further understanding of miRNA function in the regulation of the plant Zn deifciency response and its impact on plant growth and development.
