The improving effect of shallow ploughing and deep digging to low-wet soil was studied in this paper. The result showed that shallow ploughing and deep digging could decrease soil volume weight, increase soil porosity , raise soil temperature, enlarge soil permeability, enhance the ability of waterlogging resistance and moisture preservation of low-wet soil and increase crop yield and is a effective method to improve low-wet soil.

本文通过大区对比法对浅翻深松改良低湿耕地的效果进行研究。结果表明:浅翻深松降低土壤容重.增加土壤孔隙度.提高地温.增加土壤渗透性.增强了低湿耕地的抗涝保墒能力,提高了作物产量,是低湿耕地改良的有效措施。

Utilizing the resource of saline and alkaline land, ameliorating the salinization cropland, are the important link of the developing agricultural production ,in regions of saline and alkaline land. The area of the saline and alkaline land in Xinjiang which have 21 814 thousand hectare, is 22.01% by comparison with the total area of saline and alkaline land of the whole country. The area that have being imperiled in different degree by salinization take 30.12%, in 4 078.4 thousand hectare of the cropland in Xinjiang....

Utilizing the resource of saline and alkaline land, ameliorating the salinization cropland, are the important link of the developing agricultural production ,in regions of saline and alkaline land. The area of the saline and alkaline land in Xinjiang which have 21 814 thousand hectare, is 22.01% by comparison with the total area of saline and alkaline land of the whole country. The area that have being imperiled in different degree by salinization take 30.12%, in 4 078.4 thousand hectare of the cropland in Xinjiang. Biotic reclamation of the saline and alkaline land means the direct planting of the salt- enduring plant in salinization land, in conventional irrigation, not to require any subsidiary condition and facilities,in which the soil salinity is retained beyond the root system zone in soil profile. The plant produce of the flooding form is in favor of this kind ameliorative mode in Xinjiang. Biotic amelioration mode, the irrigative water is high utilized by plants,in favor of the favorable circulation and perpetual build of the ecological environment system. When the salt-enduring plant of the more root system and the deep root system is planted,the salinity move down deep in soil profile,with the irrigation.

盐碱地资源的利用、盐渍化耕地的改良 ,在有盐碱地的地区 ,是农业生产发展的重要环节之一。新疆盐碱地总面积 2 181.4× 10 4 hm2 ,占全国盐碱土 (9913× 10 4 hm2 )面积的 2 2 .0 1% ;在 40 7.84× 10 4 hm2 耕地面积中 ,受不同程度盐化危害的面积占 30 .12 %。生物改良盐碱地 ,指利用耐盐植物直接种植 ,通过常规灌溉 ,不需要任何附加条件和设施 ,将土壤盐分控制在植物根系土层以下的土体中。新疆漫灌式种植生产有利于这种生物改良。生物改良盐碱地 ,灌溉水利用率高 ,又利于生态环境的良性循环和永久性建设。种植根系较多、较深的耐盐植物 ,土壤盐分在灌水条件 ,向下移动较深。

The biomass of Medicago sativa,Brassica campestris, Pisum hypogaea of bled plant community in growth period was steadied The results showed:there is obvious difference among to biomass of each type and growth rate in growth season The summit period of growth rate was the July in Brassica campestris and Pisum hypogaea, the August in Medicago sativa, the June in the Forbes and grass Medicago sativa blended to seed with another corps in the improved wchltvoted land That not only was benefited to the rate of emergence and keeping seedlings but also improved production increased benefit of manmade meadow in same year

对紫花苜蓿、油菜、碗豆混播植物群落 ,在生长季各类群生物量测定结果表明 :各类群生物量季节动态具有明显的差异 ,其生物量生长速率也各不相同。其中 ,油菜和碗豆生长速率的高峰期在 7月 ,紫花苜蓿在 8月 ,禾草类和杂草类在 6月。试验结果同时说明 ,弃耕地改良后作为刈割和放牧用地 ,苜蓿和其他作物混播不仅有利于当年播种苜蓿在退化盐碱地上的出苗率和保苗率 ,而且可提高人工草地产量 ,增加草地当年收益
