不同叶面肥对芦笋长势和产量效应的研究

通过对几种不同叶面肥在芦笋上施用作对比试验,以探讨对芦笋的长势和产量的影响。采用单因素方差分析,研究了芦笋株高、茎粗与产量之间的相关性,建立了相应的多元回归方程。结果表明:芦笋在施用生物有机肥的基础上分别喷施叶面宝、害立平、喷施宝及清水对芦笋的长势与产量均产生不同程度的效应,其中喷施叶面宝对芦笋株高、茎粗和产量的影响均优于其它叶面肥。与对照相比,芦笋株高、茎粗和产量的差异均达到极显著水平。喷施害立平与对照相比,芦笋株高和产量的差异达到显著水平,而喷施喷施宝与对照相比差异不显著。喷施叶面宝产量最高(3 361.5 kg/hm2),经多元回归统计分析,喷施叶面肥芦笋的株高、茎粗与产量呈正相关,其相关系数R=0.996 343。

A Study on the Effect of Leaf Fertilizer on Asparagus Growth and the Production

Through compareing the results of spraying three different leaf fertilizers to asparagus,the effects of spraying different leaf fertilizers on the growth and production of asparagus was studied.Based on the single factor variance analysis,the regressive equations of the relationship between the asparagus' shoot height,the stem thickness and the effects on the yield of asparagus were established.The results indicated that the effects of spraying different leaf fertilizers upon the shoot height,stem thickness,and the yield of asparagus were obviously different under the condition of the same level of bio-organic fertilizers applied.The effect of yemianbao on the shoot height,stem thickness and the yield of asparagus was much superior to the effect of hailiping or penshibao.Compared with the cotrol,which was sprayed with plain water,the discrepancy of the shoot height,stem thickness and the yield of the asparagus sprayed with yemianbao was the most remarkable,and the discrepancy of those sprayed with hailiping was remarkable,while the discrepancy of those sprayed with penshibao was unremarkable.Proved by multistatistical analysis,the shoot height and the stem thickness of asparagus were positively correlative to its output and the correlative coefficient was 0.996 343.
