有机肥对茄子生长发育及抗病性的影响

Effect of Organic Manure on Eggplant Growth and Disease Resistance

采用施用不同水平鸡粪和猪粪试验,研究了2种有机肥对茄子产量、生长发育和抗病性的影响。结果表明:在设定的施肥量范围内,2种有机肥的施肥量与产量均呈良好的线性关系,线性方程为^y鸡粪=14 222+0 4864x,相关系数r=0 9408,达显著水平;^y猪粪=13 896+0 5008x,相关系数r=0 9852,达极显著水平。有机肥可提高茄子单果重和单株结果数,改善植株的生长发育条件,减轻茄子黄萎病的危害。最适施肥量为猪粪5 0～10 0t 667m2,鸡粪2 5～5 0t 667m2。

By applying different lever chicken excrement and pig excrement, the effect of two kinds of organic manure on the growth of eggplants was appraised. The results showed that the application of organic manure might enhance eggplant yield in the supposedly applied scope, and there existed good linear relations between organic manure quantity and eggplant yield The relation of applying chicken excrement and yield showed that it achieved remarkable level, such as =14222+0486 4x,and the interrelated coefficient r=0940 8, while the relation of applying pig excrement and yield showed that it achieved remarkable level, such as =13896+0500 8x, and the interrelated coefficient r=0985 2 Organic manure might improve the number of singleplant fruit, single fruit weight and agricultural characters of eggplant, and retard the harm of verticillium wilt on eggplant The most appropriate amount of chicken excrement was in the scope of 25～50 t/667 m2, and that of pig excrement was in the scope of 50～10 t/667m2.
