[目的]为了研究沼肥不同组合对马铃薯生长性状及产量的影响;[方法]试验共分5个处理组,每个处理组3个重复,每个重复22 m2,CK不施任何肥,试验Ⅰ组底肥施化肥,使用尿素进行追肥,试验Ⅱ、试验Ⅲ、试验Ⅳ组统一以沼渣作基肥,分别使用30%、50%和70%沼液进行追肥,试验期间各组管理均相同;[结果]结果表明:1沼液浸种,沼渣作基肥,可明显提高马铃薯的出苗率,延长成熟期和生育期。2以沼液浸种,各个试验组长势均较好,叶色均为深绿色,在株高方面,试验Ⅲ为110.25 cm,分别比试验Ⅰ、试验Ⅱ、试验Ⅳ和CK提高了16.82%(P<0.5)、7.70%(P>0.5)、12.63%(P>0.5)和38.42%(P<0.01);茎粗方面,试验Ⅲ为2.05 cm,分别比试验Ⅰ、试验Ⅱ、试验Ⅳ和CK提高了18.50%(P<0.5)、10.81%(P>0.5)、15.00%(P>0.5)和43.36%(P<0.01);分叶数方面,试验Ⅲ为17.2枝,分别比试验Ⅰ、试验Ⅱ、试验Ⅳ和CK提高了16.22%(P<0.5)、6.20%(P>0.5)、17.81%(P<0.5)和66.99%(P<0.01)。3亩产量试验Ⅲ组为3 031 kg,分别比试验Ⅰ、试验Ⅱ、试验Ⅳ和CK多产696 kg、363 kg、545 kg和1 467 kg,试验Ⅲ组分别比试验Ⅰ、试验Ⅱ、试验Ⅳ和CK多收入1 044元、544元、819元和2 200元,效果十分显著。[结论]使用沼液浸种,沼渣作基肥,沼液进行追肥,可显著促进马铃薯的生长,增加经济收入,其中底肥施入沼渣4500 kg/667 m2,追肥以喷施50%沼液效果最好。
[Objective] The research aimed to study the effects of different combinations of biogas fertilizer on the growth traits and yield of potato. [Method] The experiment was divided into five treatment groups with three replicates in each treatment group. In the first group, chemical fertilizers were applied at the bottom and urea was used for top dressing. In experiment Ⅱ, Ⅲ and Ⅳ, biogas residue was used as basal fertilizer, and 30%, 50% and 70% [Result] The results showed that: 1 biogas slurry soaking, biogas residue as basal fertilizer, can significantly improve the emergence rate of potato, to extend the maturity and growth period. 2 soaked in biogas slurry, the growth of each experimental group was good, the leaf color was dark green, the test Ⅲ was 110.25 cm in plant height, which was 16.82% higher than that of test Ⅰ, test Ⅱ, test Ⅳ and CK <0.5), 7.70% (P> 0.5), 12.63% (P> 0.5) and 38.42% (P <0.01) respectively. (P <0.05), P <0.05), P <0.5%, P <0.05), P <0.05) Test II, IV and CK increased 16.22% (P <0.5), 6.20% (P> 0.5), 17.81% (P <0.5) and 66.99% (P <0.01). The yield of the three-acre experiment group Ⅲ was 3 031 kg, which was 696 kg, 363 kg, 545 kg and 1 467 kg more than that of the test Ⅰ, Ⅱ, Ⅳ and CK, respectively. Ⅳ and CK more than 1 044 yuan, 544 yuan, 819 yuan and 2 200 yuan, the effect is very significant. [Conclusion] Using biogas slurry soaking and biogas residue as basal fertilizer and biogas slurry for topdressing could significantly promote the growth of potato and increase economic income. The bottom fertilizer was applied to 4500 kg / 667 m2 of biogas residue and sprayed with 50% biogas slurry the best.
