种植苜蓿、草木樨,对改良土壤、增进地力、提高粮棉产量,有良好的作用.但保苗上还存在一些问题,故全疆各地尚未普遍种植.因此,我们在阿克苏塔里木垦区进行了保苗技术调查和试验.一、土壤含盐量与保苗关系苜蓿、草木樨苗期生长缓慢,抗盐力弱;随着植株的成长,耐盐力逐渐提高.垦区土壤有不同程度的盐渍化,一般属轻盐渍化土壤.但大多数生产单位,在含盐较重的土地上安排苜蓿、草木樨,影响种子发芽和出苗.我们在农一师农科所试验结果:不同盐水浓度,影响苜蓿、草木樨发芽率很大.盐水浓
Planting alfalfa and mulberry trees has a good effect on soil improvement, soil fertility enhancement and grain and cotton yield improvement, but there are still some problems in seedling conservation, so the planting of seedlings in Xinjiang has not yet been carried out universally. Therefore, we carried out seedling conservation techniques in the agro-Tarim reclamation area Investigation and experiment.First, soil salinity and seedling protection relationship Alfalfa, grass mulberry seedling stage of slow growth, salt resistance is weak; with the growth of plants, salt tolerance gradually increased.The reclamation area soil has varying degrees of salinization, general Is light salinization of soil, but most of the production units, alfalfa, licorice on the saltier land, affecting seed germination and emergence of the results of our experiment in Nong Yishi Division: different salt concentrations affect the alfalfa , The rate of germination is very high
