Vegetable of the mustard family, better like the mouthfeel after the scald such as orchid, cauliflower passes on the west, they contain rich cellulose to be digested more easily also; Spinach, bamboo shoot, wild rice stem contain the vegetable with more oxalic acid best also scald, it is difficult to because oxalic acid is inside alvine path,be become with calcic union synthetic oxalic acid is calcic, disturb the human body absorption to calcium; The mustard such as rutabaga kind vegetable contains glucoside of sulfur acting grape, shui Chao, hydrolysis have a youthful look becomes volatile mustard oil, taste is better, and can promote digest absorb; Dust of can complete purify mixes the potherb scald such as purslane small bug, still can prevent allergy.

十字花科蔬菜，如西兰花。菜花等焯过后口感更好，它们含有丰富的纤维素也更轻易消化；菠菜。竹笋。茭白等含草酸较多的蔬菜也最好焯一下，因为草酸在肠道内与钙结合成难吸收的草酸钙，干扰人体对钙的吸收；大头菜等芥菜类的蔬菜含有硫代葡萄糖甙，水焯一下，水解后生成挥发性芥子油，味道更好，且能促进消化吸收；马齿苋等野菜焯一下能彻底去除尘土和小虫，还能防止过敏。

A method combining HPLC, a post-column derivation device and a fluorescent detector was used to determine residues of ten carbamate pesticides （aldicarb sulfoxide, aldicarb sulfone, oxamyl, methomyl, 3-hydroxy carbofuran, aldicarb, propaxur, carbofuran, carbaryl and methiocarb） in 68 vegetable and 32 soil samples under four different cultivation systems （traditional kailyard, open field vegetable base, green house and paddy） were collected from a certain city in South Jiangsu.

本研究采用高效液相色谱-柱后衍生-荧光检测法分析了苏南某市4种不同种植方式下（传统菜地、露天蔬菜基地、大棚蔬菜基地和水稻田）68个蔬菜样品和32个土壤样品中10种N-甲基氨基甲酸酯类农药（涕灭威、涕灭威砜、涕灭威亚砜、杀线威、灭多威、残杀威、克百威、3-羟基克百威、甲萘威和灭虫威）的残留量，结果表明在蔬菜中检出的氨基甲酸酯农药残留水平多处于0.2～23μgkg^-1，土壤中为0.1～10μgkg^-1；土壤中3-羟基克百威和灭虫威全部检出，其最高检测浓度分别为10μgkg^-1和1.64μgkg^-1，其他农药仅有少数检出。

The degree of nitrate pollution was up to serious (NO3-3 100 mg/kg)or high(NO3-1 440 mg/kg) for 34%~100% flowering Chinese cabbage,23%~46% Chinese cabbage and 25%~57% green leaf vegetables,while was up to less for 50% gourd vegetables,bean vegetables and solanaceous fruits.

而瓜类、豆类、茄果类最低，平均含量为480 mg/kg。蔬菜硝酸盐污染达严重至高度污染水平的超标率，菜薹类、白菜类和空心菜等绿叶类蔬菜分别为34%~100%，23%~46%，25%~57

The correlation analysis in the different vegetable kinds shows that the correlation degree is bigger in leaf vegetable than in fruit and vegetable. The correlation analysis of heavy metals displays the correlation degree of the different vegetable breeds is bigger in asparagus lettuce than in cabbage than in kidney bean than in onion than in hot pepper than in raw vegetable than in three-coloured amaranth.

不同蔬菜种类相关性分析表明相关性程度为叶菜类＞果菜类，不同蔬菜品种相关程度为莴笋＞莲白＞四季豆＞葱子＞海椒＞生菜＞苋菜。

In order to study the relationship between vegetable quality and water, nutrition supply, the effects of different water and nutrition supply on the growth of lettuce, melon were investigated, and the effects of grafting on quality of cucumber, melon and watermelon were studied.

根据蔬菜生产实际和消费者对蔬菜营养品质的需求，重点开展了嫁接对瓜类蔬菜品质、不同水肥条件（不同灌溉模式、营养条件）与生菜和甜瓜品质等方面的研究，提出了适合上述蔬菜品质形成的高效水肥调控技术。

Among these species, 180 for annuals and biennials, 20 for perennials and 13 species are flowering shrubs. Concerned about the adaptability for local environment and the sight impression, 81 well-behaved species were introduced.

其中一、二年生观赏蔬菜180种，多年生20种，花木类13种；结合观赏蔬菜的生长适应性和景观应用效果，进一步筛选出山东地区适宜的观赏蔬菜种类81种。

But along with the social economy development, the vegetables consumption quantity is daily increased, the great scale of the greenhouse vegetables production is higher and higher day after day and a special reason is benefit actuation. It emerges one batch of vegetables types relatively sole specialized production base one after another, which causes the original cropping system to disintegrate objectively, the farmer who is engaged to run some specific vegetables production is increased day by day, the vegetables type are restricted frequently by the high production and economic efficiency fruit vegetables, the tendency of specialized production is suddenly revealed day after day, finally is causes the soil environment to worsen, the vegetables plant disease to be serious, the output to reduce, the quality and the series barrier of continuous copings to occur and the facility vegetables production further development to be cut down.

但随着社会经济的发展，蔬菜消费量的日益增加，温室蔬菜规模化生产日渐升温，加上效益驱动等原因，相继涌现出一批蔬菜种类相对单一的专业生产基地，客观上导致原有耕作制度瓦解，从事某一特定蔬菜生产的农民日益增多，蔬菜种类常常局限于生产经济效益高的果菜类，专业化生产趋势日渐突显，结果导致土壤环境恶化、蔬菜病虫害严重、产量降低、品质下降等一系列连作障碍的发生，严重威胁着设施蔬菜生产的进一步发展。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
