摘要

为探明秸秆颗粒改良剂对川西北高寒沙地土壤氮素和黑麦草生长的影响，以农业废弃物（秸秆）为主要原料，复合聚丙烯酰胺、微生物菌剂和氮磷钾肥，加工成秸秆颗粒改良剂，设4个施用量水平（6，12，18，24 t/hm2），以空白对照（CK0）和当地常规牦牛粪处理（CK1）为对照。结果表明：与CK0相比，秸秆颗粒改良剂和CK1均能显著增加土壤全氮、全氮密度、全氮储量和硝态氮含量，增加黑麦草株高、总根长、总根表面积、总根体积、平均根系直径和单株干重（p<0.05），达到增加土壤氮素含量和促进黑麦草生长的效果。与CK1相比，秸秆颗粒改良剂处理的平均全氮含量、全氮密度、全氮储量和硝态氮含量分别增加了12.50%，22.73%，20.90%和344.56%，黑麦草地上和地下部平均单株干重分别增加了57.50%和66.86%。增施秸秆颗粒改良剂可有效增加土壤氮素含量，黑麦草各生长指标也随改良剂施用量增加呈逐渐增加的趋势。施用量超过18 t/hm2时，0—10 cm土层的全氮、全氮密度、全氮储量和黑麦草各生长指标差异不显著。土壤氮素指标与黑麦草单株干重存在正相关关系，其中土壤全氮、全氮储量与黑麦草单株干重的相关性最高（r≥0.90**）。随改良剂施用量增加，外源养分淋溶率呈先降低后升高的趋势，在18 t/hm2处有最小值。综合考虑土壤氮素含量、外源养分淋溶率和黑麦草生长的变化，秸秆颗粒改良剂以18 t/hm2为川西北沙地土壤改良的最佳施用量。

Abstract

Soil desertification is one of the most serious environmental problems in the world.Soil fertilization and vegetation restoration are the key links in desertification governance. As a agricultural waste

crop straw still retains rich organic matter and nitrogen

phosphorus and potassium nutrients

and is a natural organic amendment. Granulation of straw can significantly improve straw returning and improve soil fertility.Using agricultural waste (straw) as the main raw material

adding polyacrylamide

microbial agents and NPK fertilizers

and processing them into granulated straw amendment (GSA).In order to investigate the effects of GSA on soil fertilization and vegetation growth in the alpine sandy land of Northwest Sichuan

a field experiment with blank control (CK0)

local conventional yak dung treatment (CK1) and four application levels of GSA (6

and 24 t/hm2)were conducted.The results showed that compared with CK0

both GSA and CK1 significantly increased soil total nitrogen

total nitrogen density

total nitrogen storage and nitrate nitrogen content. GSA and CK1 also increased the plant height

total root length

total root surface

average root diameter

root volume and dry weight of single plant (DWSP) of ryegrass(p<0.05). The application of GSA and CK1 increased the soil nitrogen content and promoted the growth of ryegrass.The effect of GSA on the nitrogen content of sandy soil and the growth of ryegrass was better than that of CK1. Compared with CK1

the average of total nitrogen content

total nitrogen density

total nitrogen storage and nitrate nitrogen content increased respectively by 12.50%

22.73%

20.90% and 344.56% under the treatment of GSA.The average of shoot and root DWSP of ryegrass also increased respectively by 57.50% and 66.86%

when compared to CK1. Increasing the application rate of GSA can effectively increase soil nitrogen contentand the growth indexes of ryegrass also increases gradually.When the application rate exceeds 18 t/hm2

the total nitrogen content

total nitrogen density and total nitrogen storage in the 0-10 cm layer

and the growth indexes of ryegrass are not significantly different.There was a significant correlation between soil nitrogen and DWSP of ryegrass

and the correlation between soil total nitrogen and total nitrogen and DWSP of ryegrass was the highest (r ≥ 0.90**).The leaching rate of exogenous nutrients decreased at first and then increased with increasing the application rate of GSA

with a minimum at 18 t/hm2. Considering the changes of soil nitrogen content

exogenous nutrient leaching rate and growth of ryegrass

the optimum application rate of GSA in sandy soil of northwest Sichuan is 18 t/hm2.
