良好的水管理与适当的土壤管理相结合，是旱地可持续作物生产的必要条件。在温室条件下，采用盆栽试验研究了沙丘土对小麦（Triticum aestivum L.）施用农家肥（FYM）或家禽粪便（PM），并在两个盐度水平（0.11和2.0 dS m（-1））和两个灌溉间隔（每天和每隔一天）下用水灌溉。粪肥的施用量为20毫克/公顷。每次灌溉前1h测量的土壤含水量表明，PM处理的土壤比FYM处理的土壤保留更多的水分，而对照（无粪便）含水量最少。FYM处理的干物质产量分别比对照和PM处理高78%和21%。当每天使用盐水灌溉时，分别增加了29%和55%。隔日灌溉处理也有类似的趋势，FYM的干物质产量最高。分蘖数和株高表现为FYM优于PM，在优质水灌溉下，无论灌水间隔如何，PM均优于对照。当用高盐水灌溉时，FYM仍然是最好的，但对照现在优于PM处理。与FYM和对照处理相比，在实验结束时测量的土壤电导率略高于PM。一个显着的灌溉水质和施肥之间的相互作用，影响植物生长。PM通过增加土壤盐分，加重了咸水对植物生长的不利影响。(C)2009 Elsevier B.

Good water management combined with appropriate soil management is necessary for sustainable crop production in drylands. A pot culture experiment was conducted using sand dune soil under greenhouse conditions to evaluate the response of wheat (Triticum aestivum L.) to the application of farmyard manure (FYM) or poultry manure (PM), and irrigation with water at two salinity levels (0.11 and 2.0 dS m(-1)) and two irrigation intervals (daily and every second day). The manure was applied at a rate of 20 Mg ha(-1). The soil water content, measured 1 h before every irrigation, showed that soil treated with PM retained more water than that treated with FYM, while the control (no manure) contained the least water. FYM treatment resulted in 78 and 21% higher dry matter yield compared to the control and PM treatments, respectively, under daily irrigation using good-quality water. The increase was 29 and 55%, respectively, when saline water was used for daily irrigation. A similar trend was observed with the alternate day irrigation treatment; FYM gave the highest dry matteryield. The number of tillers and plant height showed that FYM was better than PM, which in turn was better than the control under irrigation with good-quality water regardless of the irrigation interval. When water of the highest salinity was used for irrigation, FYM was still always the best, but the control was now better than the PM treatment. The electrical conductivity of the soil measured at the end of the experiment was slightly higher with PM, as compared to the FYM and control treatments. A significant interaction between irrigation water quality and manure application was observed, affecting plant growth. PM aggravated the adverse affect of saline water on plant growth by increasing soil salinity. (C) 2009 Elsevier B.V. All rights reserved.
