Afforestation of poplar in arid zones by irrigation can protect farmland and prevent windburn as well as drain off ground water by transpiration of trees which can avoid the soil secondary saline-alkalizing, provide timber and benefit the terms of ecology. Arid zones are perpetually short of water, so developing poplar forest must increase income and decrease expenditure of water, utilize it resaonably, accomplish balance between water and land. Planting poplar belted along the sides of irrigation ditch where if there is non-protection against seepage. This side, especilly the inside slope of irrigation ditch has enough soil water for trees to grow without special irrigation, using manpower, earth and water sparingly. Therefore, this sites are the major places for poplar's afforestation in arid-irrigated farmlands which have great potentialities. Afforestation of poplar by irrigation at some stretched lands which abounded with water and earth resources are also an important way in arid zones. Euphrates poplar(populus euphratica ) is a major species at saline and alkaline soil in arid zones where it occupies a major place. At summer draw the rich flood to the natural forest to promote it regeneration and growth by natural seeding, sprouting and rejuvenation. At present,owing to the afforested site unsuitable, planted too close, managed extensively, harmed by diseases and insect or stocks, especially irrigated insufficiently, the forest of poplar is relatively poor in many arid zones. In future, these problems must be surmounted so that can be developed more well and quickly.

干旱地区杨树灌溉造林可以防风护田、生物排水、提供木材和其他林副产品、改善人类的生态环境,具有重要的意义。干旱地区水分不足,通过灌溉可以发展杨树,但必须开源节流,合理用水,做到水土平衡。沿渠带状造林省水省地省工,林木生长好,效益高,应作为主攻方向,水土条件好的地方可以发展杨树片林,此外,胡杨的引洪灌溉造林和盐碱地造林也很有发展前途。当前干旱地区杨树灌溉造林的水平不高,生长量低,还有相当大的潜力,除管好现有林木,促进生长,提高质量外,今后发展中必须注意克服以往造林中选地和造林技术不当、树种单纯、造林过密、管理粗放、灌水不足、牲畜及病虫危害等问题。本文在调查研究和田间试验的基础上,结合有关资料,对干旱地区杨树灌溉造林中的一些问题进行初步的探讨。

There is a large area of saline-alkali soil in Hebei province, it has not been utilized fully, especial for the afforestation.By the means of experiments, it is confirmed that Salix mongolica Sivzev is a good species for afforestation on the soline-alkali soil and its saltresistance concentration is 0.2—0.4%, much better than that of S. matsudana Koidz and S.babalonica L..

河北盐碱地面积较大,开发利用不充分,尤其是盐碱地造林发展缓慢。本文通过试验证实沙柳(Salix mongolica Sivzev)具有抗0.3%~0.4%盐碱能力,比旱柳(S.matsudana Koidz)、垂柳(S.babylonica L.)抗盐能力强,是优良高效盐碱地造林树种。并为在盐减地建立柳编基地提供了利学依据,为引种沙柳和开发盐碱地指出了新途径。

By studying the increment of plantations of 11 years old growing, on sodasaline-alkali soil, it showed that if some suitable treatments are used plantations can grown and established on the soil of soda-saline-alkali with the soil condition of pH-value 8.5~9.6, salinity 0.1%~0.3%, sodiumionized ratio 16%~51% and normality ratio of saline base Na~+/(Ca~(++)+Mg~(++))>4. From the results of plot inventory and tree stem analysis, the increment of populus simonigra is highest. For 9 years old plantation the volume...

By studying the increment of plantations of 11 years old growing, on sodasaline-alkali soil, it showed that if some suitable treatments are used plantations can grown and established on the soil of soda-saline-alkali with the soil condition of pH-value 8.5~9.6, salinity 0.1%~0.3%, sodiumionized ratio 16%~51% and normality ratio of saline base Na~+/(Ca~(++)+Mg~(++))>4. From the results of plot inventory and tree stem analysis, the increment of populus simonigra is highest. For 9 years old plantation the volume can reach 100 m~3/hm~2, the biomass (above ground) can reach 28.7 ton / hm~2. Populus simonigra grows very well on the all kinds of soda-saline-alkali soils except for the alkali spot with the worst soil condition. So populus simonigra is a good tree species for planting on the soil of soda-saline-alkali.

对生长在苏打盐碱地上11年生的人工林调查研究表明:采取合理的造林技术措施,人工林可以在pH值8.5~9.6,含盐量0.1%~0.3%,钠化率16%~51%,盐基当量浓度比值Na~+(Ca~(++)+Mg~(++))≥4的苏打盐碱地上生长良好,郁闭成林,根据标准地调查和树干解析,小黑杨生长量最高,9年生蓄积可达100m~3/hm~2,地上部分生物量可达28.7t/hm~2。小黑杨可在土壤条件极其恶劣的碱斑以外的各种盐碱地上生长良好,是一个良好的苏打盐碱地造林树种。
