- 摘要:
- 沼肥是一种优质的有机肥料,含有植物生长所需的多种营养元素,将其安全有效地应用于农业生产对降低环境污染和提高产量有着重要的意义。在田间小区试验条件下,以籼稻黄华占为试验材料,研究不同体积的沼肥施用量对水稻生长发育、养分含量和产量及其重金属含量的影响。结果表明:以沼肥作基肥,追施复合肥对水稻生长株高、茎叶生长及养分含量均有一定影响,水稻产量最高可达562.03 kg·667 m2。同时,当沼肥施用量较高时,会增加收获籽粒中的重金属含量。
- Abstract:
- Biogas fertilizer is a high quality organic fertilizer,which include various kinds of nutrient needed for plant growth.It has great significance to apply it safely and effectively to agricultural production to reduce environmental pollution and increase yield.The effects of different biogas fertilizer application amount by different volume on rice growth and development,nutirent content,yield and content of heavy metals in rice seeds of the Indica rice Huanghuazhan were studied with series of field trials.The results showed that the height of plant,stems and leaves growth and nutrient content of rice were affected by the use of biogas as base fertilizer and the compound fertilizer as supplemental fertilizer,the yield per 667 m2 of rice could reached 562.03 kg.Meanwhile,the results also showed that the content of heavy metals in the harvested grains were increased when the high application amount of biogas fertilizer.
