不同微生物菌剂浸种对马铃薯生长发育及薯田土壤养分的影响
Effects of the growth and development of potatoes and soil nutrients in potato fields based on soaking seeds with different microbial agents
摘要
Abstract
[Objective]To explore the effects of different microbial agents on potato growth and development and soil nutrients in potato fields,so as to provide a reference for green and sustainable potato planting in Inner Mongolia.[Methods]Potato V7 was used as the test material,by setting distilled water(CK),applying Bacillus sp.188 bacterial agent(T1),Pseudomonas sp.BP16 bacterial agent(T2),and Streptomyces rochei D74 bacterial agent(T3)four treatments to soak the seeds for 30 min.Potato yield,tuber starch content,dry matter mass of each organ,nutrient accumulation per plant,leaf chlorophyll content,nitrate reductase activity,soil ammonium nitrogen,nitrate nitrogen,available phosphorus and available potassium content were measured at different growth stages after potato planting.[Results]After 110 days of potato planting,compared with CK,the yield of potato in T2 and T3 treatments was significantly increased by 7.14%and 9.16%(P<0.05),the starch content of tubers was significantly increased by 11.84%and 16.38%(P<0.05),the dry matter mass of potato roots,stems,leaves,and tubers were significantly increased by 26.87%,16.92%,11.77%and 13.59%by T3 treatment(P<0.05),the accumulation of nitrogen,phosphorus and potassium in plants was significantly increased by 28.86%,32.78%and 30.81%by T3 treatment(P<0.05).After 70 days of potato planting,the chlorophyll content in potato leaves treated with T3 treatment was the highest[4.29 mg/(g·FW)],and the nitrate reductase activity in the leaves was significantly increased by 15.29%compared to CK(P<0.05).After 50 days of potato planting,the soil nitrate nitrogen content in T3 treatment reached its maximum value(42.32 mg/kg),the available phosphorus content significantly increased by 26.17%compared to CK(P<0.05),and the available potassium content in T1 and T3 treatments significantly increased by 24.95%and 21.65%compared to CK(P<0.05),respectively.After 70 days of planting,the soil ammonium nitrogen content in T2 treatment significantly increased by 47.03%compared to CK(P<0.05).[Conclusion]Soaking seeds with Streptomyces rochei D74 microbial can increase potato yield,tuber starch content,dry matter mass of each organ,plant nitrogen,phosphorus and potassium accumulation,at agent tuber formation stage,the leaf chlorophyll content at maturation stage,soil nitrate nitrogen,available potassium,available potassium content at early growth stage,soil ammonium nitrogen at agent tuber formation stage.It can be used as a suitable microbial agent for potato cultivation in Inner Mongolia Autonomous Region.关键词
