向沙地加入由牛粪分别与棉秆、玉米秆和麦糠发酵而成的肥料,然后种植梭梭与白梭梭,研究发酵肥料对土壤水分和植物生长的影响。结果表明:仅施加1.6%的发酵肥料,不能明显提高土壤含水率;发酵肥料提高了植物的存活率,梭梭的存活率平均比对照高28.1%,白梭梭平均比对照高3.6%;发酵肥料能提高梭梭、白梭梭株高生长量,梭梭、白梭梭肥料处理的累积株高生长量平均比对照高20.3 cm、18.8 cm,两种植物的月生长量与对照差异达显著或极显著水平(P<0.05,P<0.01);发酵肥料能够明显提高两种植物的单枝生长量,肥料处理的月生长量与对照的差异达显著或极显著水平(P<0.05,P<0.01),两种植物肥料处理的累积单枝生长量平均比对照高30.4 cm、25.0 cm。
Fermentation of cow dung, cotton stalks, corn stalks and wheat bran, respectively, was added to the sandy soils, and Haloxylon ammodendron and Haloxylon ammodendron were planted to study the effects of fermented fertilizers on soil moisture and plant growth. The results showed that only 1.6% fermented fertilizer could not increase the soil water content obviously. Fermented fertilizer increased the plant survival rate, the average survival rate of Haloxylon ammodendron was 28.1% higher than that of the control and the average white Haloxylon ammum 3.6% higher than that of the control. Fermentation Fertilizer can increase the height growth of Haloxylon ammodendron and Haloxylon ammodendron, and the accumulated plant height growth of Haloxylon ammodendron and Haloxylon ammodendron was 20.3 cm and 18.8 cm higher than that of the control, respectively. The monthly growth of two plants was significantly different from that of the control Or significantly (P <0.05, P <0.01). The fermented fertilizer significantly increased the single-branch growth of the two plants, and the difference between the monthly growth of fertilizer treatment and the control was significant or extremely significant (P <0.05, P < <0.01). The average single shoot growth of the two plant fertilizers was 30.4 cm and 25.0 cm higher than that of the control.
