【摘要】 本文以L402番茄为供试品种,用Lg(34)正交表安排试验,以等氮、等磷、等钾为前提条件,将沼液与普遍施用的化肥、化肥-沼液混施(各占50％)进行对比试验,辅以根外追施沼液,研究不同施肥量、施肥种类及叶面喷施沼液浓度的不同水平组合对番茄产量、品质及植株生理活性指标的影响,用力差分析法分析试验结果。通过试验表明,施用沼液或化肥-沼液混施及叶面喷施沼液,不仅能提高番茄产量,改善番茄果实的品质,而且能提高番茄植株的生理活性。因此在实际生产中可用沼液全部或部分替代化肥,既节省了资金,改善了环境,又为无公害蔬菜生产提供了一条有效的途径。更多还原

【Abstract】 This paper has studied the effect of different combinations of fertilizer type, amount of fertilizer and concentration of biogas slurry sprayed on leaves on yield, quality of tomato and physiological activity of tomato plant. In this experiment, L402 tomato variety is utilized as sample and L9(34) orthogonal array is adopted under the conditions of equal content of total N,P,K. The fertilizer used in the experiment are biogas slurry, chemical fertilizer and the mixture of biogas slurry and chemical fertilizer (each takes 50%),respectively.The experiment results show: applying biogas slurry or the mixture of biogas slurry and chemical fertilizer together with biogas slurry spraying on the tomato leaves can not only increase the yield of tomato, improve the quality of tomato fruit, but also promote the physiological activity of tomato plant. So in practical production the biogas slurry can be used to replace chemical fertilizer partly or completely, thus both save the money, improve the environment and provide an effective way for non-harmful vegetable production.更多还原
