The results showed that K.sieversiana could grow under high salt-alkaline conditions even when the salinity reached 500mmol and pH10.51. It was proved that K.sieversiana was a halophyte species with great tolerance to salinity and alkalinity.

结果表明：碱地肤幼苗在盐度为500mmol，pH10.51的高盐高碱条件下还能生长，证明了它是既高度耐盐又高度抗碱的盐生植物。

Malic acid concentration wasincreased with increasing the stress, even if its concentration was higher than that of oxalicacid.

在野外条件下，不同表型的碱地肤植株不同部位的物质积累、能量代谢呈规律的变化。

However, that alley before the village, still have name than this alkaline land, it is less than one meter wide, sinuate, winding in sight does not arrive on the saline alkaline beach of the edge; 3 days do not rain, full Lu Maobai is alkaline, far look, with respect to long and thin like white snake.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
