“稻+鱼+再生稻”模式对稻田土壤氮、磷、钾养分含量的影响
|
摘要
设置头季稻+鱼(或泥鳅)+再生稻的栽培模式,水稻品种选用黄华占和Y两优800,分析两种模式下土壤中全量氮、磷、钾含量与速效氮、磷、钾含量表现,结果表明:(1)稻鱼模式和稻鳅模式可增加土壤中全效养分含量,全氮、全磷、全钾含量在整个生育期内维持在一个相对稳定的状态,其中以稻鱼处理效果更明显,总体高于对照田。头季稻与再生季两个生育季内全氮、全磷处于相对稳定的状态,全钾含量则在再生季略有下降;(2)稻鱼模式和稻鳅模式提高了土壤中速效养分含量,孕穗期、灌浆期、成熟期含量比分蘖期时有所提升,稻鱼模式下土壤速效养分含量整体表现要高于稻鳅模式。两个水稻品种再生季的土壤速效养分含量变化规律性不明显,但整体维持在相对稳定水平。
By setting the cultivation patterns of the first season rice+fish(or loach) + ratooning rice,using two common rice varieties Huanghuazhan and Y Liangyou 800,the contents of total nitrogen,phosphorus and potassium in the soil and the available nitrogen,phosphorus and potassium contents in the two models were analyzed. The results showed that(1) Rice-fish model and rice-loach mode can increase the total nutrient content in soil. The content of total nitrogen,total phosphorus and total potassium in soil maintains a relatively stable state during the whole growth period,and the effect of rice-fish treatment was obvious. The overall was higher than the control field. The effect of rice fish model on increasing the content of nitrogen and phosphorus in soil was better than that in rice-loach mode. The total nitrogen and total phosphorus were relatively stable during the first growth period of the first season rice and the regeneration season,and the total potassium content decreased slightly during the regeneration season.(2) The rice fish model and the rice-loach mode increased the available nutrient content in the soil. The content of booting stage,grain filling stage and maturity stage increased compared with that of tillering stage. Although there were fluctuations,the overall trend was upward. Among them,the overall performance of soil available nutrient content in rice fish mode was higher than that in rice paddy mode. The regularity of soil available nutrient content in the two varieties during the regeneration season was not obvious,but the overall remained relatively stable.
