中文摘要	为了在宁夏及周边荒漠化地区实现防风固沙、保持水土和改善生态环境,引入生物基固沙新材料进行技术示范。将2种新型生物基固沙材料(生物基钙肥和生物基铵肥),按照不同的施用量喷洒在沙土表层,探究其对沙土保水性、种子生长、结皮抗压强度与pH值的影响,综合分析确定一种适合宁夏及周边荒漠化地区使用的生物基固沙新材料及施用量。结果表明: 1)生物基铵肥和钙肥与对照CK相比都有显著的保水效果,且施用量越大保水性越好, 140 g /m~2施用量下生物基铵肥的保水效果显著高于钙肥;生物基铵肥和钙肥的失水过程符合幂函数变化。 2)施用量为100和140 g /m~2时,生物基铵肥对柠条种子的发芽有抑制作用,且施用量越大抑制作用越明显,分别比对照CK低28%和50%;但生物基钙肥对柠条种子的发芽却有促进作用,分别比对照CK高12%和16%。3)生物基铵肥与钙肥都能形成良好的结皮,当施用量为100和140 g /m~2时,生物基钙肥结皮的抗压强度显著高于铵肥,分别高出59.14%和100.68%。4)生物基铵肥的结皮pH值均显著低于钙肥,施用量越大pH值越低(平均比钙肥低5.63%),且均显著低于对照CK(平均比对照低18.58%) 。综合分析2种新型生物基固沙材料的保水性、种子发芽率、结皮抗压强度和pH值得出:生物基钙肥的综合性能优于铵肥,且钙肥的最佳施用量为140 g /m~2。
英文摘要	[Background]China has the largest area of desertification ( about 27.2% of its land area) and is one of the most severely affected by windblown sand hazards in the world. Ningxia is located in northwest China with a very dry climate and is one of the worst desertification areas in China. In order to prevent desertification in Ningxia,the introduction of ecological and multi-functional sand-fixing materials is of a great significance,because it has been proved to be very effective and a trend towards desertification control in the future. Therefore,two new biological sand-fixing materials developed by Xiamen University will be tested,and the best one will be chosen for desertification control in Ningxia. [Methods]Two biological sand-fixing materials ( biological calcium fertilizer and biological ammonium fertilizer) were sprayed on the surface of sand according to different application amount ( 40 g /m~2,60 g / m~2,100 g /m~2,and 140 g /m~2 ),and their effects on water retention,seed growth,crust compressive strength and pH value were tested by a pot incubation method. The obtained data were mainly analyzed by ANOVA and plotted methods. The water retention of the sand-fixing materials was measured by weighing method,the compressive strength of the crust was measured by surcharge loading method,and the pH value of the crust was measured using a pHs-3C precision acidity meter. [Results]1) Compared with the CK ( control),both the sand-fixing materials had significant water retention effect. The water retention effect of the biological ammonium fertilizer was better than the biological calcium fertilizer under the application amount of 140 g /m~2,and the process of water loss was in accordance with power function. 2) When the application amount were 100 g /m~2 and 140 g /m~2,the biological ammonium fertilizer inhibited the germination of Caragana korshinskii seeds,which were 28% and 50% lower than that of the CK,respectively. However,the germination of the seeds of C. korshinskii was promoted by the biological calcium fertilizer,12% and 16% higher than that of CK. 3) Both the sand-fixing materials formed a fine crust,and when the application amount were 100 g /m~2 and 140 g /m~2,the compressive strength of the crust of biological calcium fertilizer was significantly higher than that of the biological ammonium fertilizer,59.14% and 100.68% higher respectively. 4) The crust pH value of the biological ammonium fertilizer was significantly lower than that of the calcium fertilizer ( 5.63% lower than the calcium fertilizer on average),but all of them were lower than CK ( 18.58% lower on average) under different application amount. [Conclusions]A comprehensive analysis shows that the performance of the biological calcium fertilizer is better than the biological ammonium fertilizer,and the optimal application dose of the biological calcium fertilizer is 140 g /m~2.
