- 摘要:
- 为探讨在提高马铃薯产量的同时改良土壤的有效方法，2011～2012年在黑龙江省农业科学院克山分院马铃薯种薯网棚内设置2种EM菌肥料处理，研究了EM菌肥料的不同处理方法对连作的马铃薯原原种生产网棚土壤及马铃薯生长的影响。结果表明：2012年秋季测得土壤真菌和细菌的数量均为处理3（常规发酵的马粪肥对照）>处理2(EM菌发酵的马粪与秸秆的混合物)>处理1（EM菌发酵的马粪肥），各处理的菌量均比2011年秋季减少；土壤放线菌的数量为处理3（对照）>处理2>处理1，各处理放线菌的数量均比2011年秋季增加，处理2增加最大。土壤容重的变化：2012年测得处理1和处理3的10,20和30 cm处的土壤容重均减低，10 cm土壤容重较未进行任何处理的空白对照降低6.1%。对马铃薯产量的影响：2012年各处理的小区产量和株高均比2011年增加，处理1和处理2的单株结薯个数也增加。
- Abstract:
- In order to study the effective method which could improve the yield of potato and the soil,effect of EM on the soil of net shed of continuous cultivation potato and yield of potato were discussed through two kinds of EM treatment,the conventional manure fermentation was as the control in Keshan branch of Heilongjiang academy of agricultural sciencs from 2011 to 2012 .The results showed that the number of fungi and bacteria was less than that in autumn of 2011,treatment 3(conventional manure fermentationcontrol)>treatment 2(mixture of straw and manure fermentation in EM)>treatment 1(manure fermentation in EM).The number of actinomyces in soil was that treatment 3(control)>treatment 2>treatment 1,the number of actinomyces was more than that in autumn of 2011.Treatment 2 was the maximum.The change of soil bulk densitiy was that the soil buik density of treatment 1 and treatment 3 were reduced than the soil undisposal,decreased by 6.1%.The effect on yield of potato was that the yield of plot and plant height were increased than that in 2011,the number of tuber per plant treatment1 and 2 were increased.
