通过田间试验研究沼气肥对土壤供氮能力以及早稻产量及其构成因素、品质性状、稻田主要病虫害的影响。结果表明:增施沼气肥可显著提高早稻的有效穗数和实粒数,显著提高产量。在等量氮磷钾下,与常规施肥相比增产17.81%。等量沼气肥下,沼气肥与常规施肥中减少20%氮和33%钾用量西施处理比与常规施肥配施处理略有减产,仅增产4.24%,但比常规施肥处理增产13.03%。施用沼气肥对早稻稻米碾米品质和外观品质影响不明显,但稻米的食味品质和营养品质明显改善。施用沼气肥还可以减轻水稻主要病虫害的发生和危害。
Field experiments were conducted to study the effects of biogas fertilizer on soil nitrogen supply, yield and its components, quality traits, and main pests and diseases in paddy fields. The results showed that increasing biogas fertilizer could significantly increase the effective spike number and grain number of early rice and significantly increase the yield. Under the same amount of NPK, the yield was increased by 17.81% compared with the conventional fertilization. Compared with the conventional fertilization, the treatment with the same amount of biogas fertilizer, biogas fertilizer and conventional fertilization reduced the yield by 20% and 33%, respectively, with a yield reduction of 4.24%, but increased by 13.03% compared with the conventional fertilization treatment. The effect of using biogas fertilizer on rice milling quality and appearance quality was not obvious, but the eating quality and nutrition quality of rice significantly improved. Application of biogas fertilizer can also reduce the occurrence and harm of major pests and diseases in rice.
