摘要: 为了研究有机肥在植物生长发育中所起到的作用,研究了3种不同种类有机肥,即普通有机肥(T1)、有机碳肥(T2)、有机全营养肥料(T3)对叶用油菜生长发育及经济效益的影响,以期为农业提供更科学、更经济的施肥方法。试验结果表明:施用有机肥提高了植株的干重、鲜重。提高了油菜叶片的叶绿素含量(SPAD值),其中最高的为T2处理,且差异极显著。不同处理后的油菜叶片净光合速率(Pn)日变化均呈双峰曲线,叶片光合午休现象不明显。3种有机肥处理的叶片Pn值在这2个峰值上与CK相比均有所提高;T2处理的2个峰值都为最高,与CK相比分别提高了32.26%和32.22%。施用有机肥均提高了油菜产值,其中T3处理最大,每公顷新增产值达到3156.75元。从新增产值/新增施肥成本上得出,T2和T3处理增值明显,每投入1元,新增产值能够分别达到10.60元和25.51元,这说明在油菜栽培上施用这2种肥料是经济可行、值得推广的施肥方法。

Abstract: In order to offer more scientific and economic fertilizing method to agriculture, the effects of three different kinds of organic fertilizers, normal organic fertilizer (T1), carbon organic fertilizer (T2) and full nutrients organic fertilizer (T3) on the growth and economic benefit of Brassica napus L. were studied in this experiment. The results showed that: the dry weight, fresh weight and chlorophyll content of Brassica napus L. increased. Compared with other treatments, T2 treatment was the highest and the difference was extremely significant. Pn diurnal variation of Brassica napus L. leaf under different treatments were bimodal curve and “midday depression” phenomenon was not obvious. Compared with the CK, Pn of the two peaks under the three treatments all increased. T2 treatment were both the highest, they increased by 32.26% and 32.26% than that of CK. All organic fertilizer treatments improved output values, and the T3 treatment was the largest, the newly added value was 3156.75 yuan per hectare. From the rate of newly added value/newly added fertilization cost, we could see that it had obviously appreciation under T2 treatment and T3 treatment, and newly added value could reach 10.60 yuan and 25.51 yuan respectively by 1 yuan investment, therefore, both the two kinds of organic fertilizers on the Brassica napus L. cultivation fertilization method was feasible and economical.
