The physiologic changes of leaf vegetables after picked and the basic principles of the technology for keeping fresh were discussed. The effect of MAP on leaf vegetables stored in different component gas at normal temperature was studied with cabbages, caraways, leeks, to select the best packaging atmosphere for keeping leaf vegetables fresh.

论述了叶菜类蔬菜采后的生理变化和气调包装保鲜的基本原理，并以小白莱、香菜和韭菜为例，对常温叶菜在不同气体成分下的气调保鲜进行了实验研究，提出了适合叶菜气调包装保鲜的最佳气氛配比。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species （ r = 0.93, p 〈 0.01）. Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher Pn, Tr and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.

这些结果表明，所观测的早春短命植物具有典型的G植物特征，相比其它类型的荒漠植物具有较高的单位叶面积Pn、高Tr及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

Moreover, pruming leaf decreased the yields of muskmelon. In contrast to the control, the yield of remained upper five-leaf treatments was close to the controls, and upper-leaf made more contribution to the fruit.

在果实成熟过程中，与下位叶处理相比，上位叶处理的果实鲜质量、干质量较高，果实横、纵径的增大速度较快，果实的内壁糖和中心糖的含量较高。

To obtain the best nutritional quality, the optimum nitrogen application is 125.8kg/hm~2 under middle density, during different development stage, the best C/N value were respectively 1.35-1.40, 1.17-1.25, 1.02-1.03, 0.62-0.71, 1.55-1.72, 0.98-1.02.8, Consequently, to obtain the unification between high yield and good quality, under the conditions of this study the optimum plant density is 60000 plant/hm2, the optimum nitrogen application is 120kg/hm2 to 180kg/hm2 under this density, it was obtained that at five-leaf, seven-leaf, ten-leaf, silking, lid after silking and harvest stage, the best C/N value were 1.27-1.63, 0.80-1.38, 0.81-1.07, 0.62-0.90, 1.39-1.72, 0.98-1.17, respectively.
