英文摘要 | Aiming at the bottleneck problems of high salinity of surface soil, poor physical and chemical properties of soil and difficult growth of plants in alkalized solonchak ofJingyuan, Gansu Province, field experiments were carried out on the basis of uniform application of desulfurized gypsum 22 t/hm(2). Three irrigation quotas: 8,625m(3)/hm(2),9,375m(3)/hm(2)and 10,125m(3)/hm(2), were set up under the two planting modes of ridge and furrow planting and non-ridge planting, and effects of two planting methods and irrigation quota on soil pH, degree of alkalisation, total salt content and wolfberry growth were studied. The results showed that: (1) The pH value, degree of alkalisation and total salt content of the soil were significantly reduced by all treatments, and the irrigation water and rainfall could be collected in the furrows, so as to increase the soil water content. The soil salinity of ridging treatment was 14.2% lower than that of non-ridge treatment in 0 similar to 40 cm soil layer, and the growth index ofwolfberry was higher than that of non-ridge treatment. Under the two planting methods, the desalting effect increased with the increase of the irrigation volume. The survival rate, plant height, crown width and yield indexes of wolfberry increased with the increase of irrigation amount. There was no significant difference in growth indexes of wolfberry when the irrigation quotas were 9,375 m(3)/hm(2) and 10,125 m(3)/hm(2). Considering that the study area is located in arid area and water resources are limited, excessive irrigation will not only waste water resources but also increase the risk of secondary salinization, therefore, ridge and furrow planting is suitable for wolfberry planting in alkalized solonchak of Baiyin, Gansu, and the appropriate irrigation quota is 9,375 m(3)/hm(2). |
