摘要
以"新龙长茄"为试材,采用日光温室全膜双垄沟播的栽培方法,研究了不施肥(CK),施100%纯化肥(T1)、75%化肥(T2)、75%化肥+25%有机肥(T3)、50%化肥+50%有机肥(T4)、25%化肥+75%有机肥(T5)、100%有机肥(T6)共7个化肥减量有机替代施肥处理对茄子农艺性状、产量和品质及土壤养分的影响,以期为日光温室茄子生产中合理施肥提供参考依据。结果表明:施肥可以促进茄子植株生长,明显提高茄子产量和土壤养分含量;与当地常规施肥相比,T1、T2处理对茄子生长、产量和土壤养分的影响均不显著;而化肥减量配施有机肥T4处理可不同程度促进茄子植株生长、提高土壤养分含量,并且可以显著增产33.74%、增加可溶性糖含量63.1%、降低硝酸盐含量35.06%。因此,50%化肥+50%有机肥(T4)的施肥对茄子生长、产量提升和品质改善具有较大的作用。
The effects of 7 fertilizer reduction organic substitution treatments of no fertilization(CK),100%fertilizer(T1),75%fertilizer(T2),75%fertilizer+25%organic fertilizer(T3),50%chemical fertilizer+50%organic fertilizer(T4),25%chemical fertilizer+75%organic fertilizer(T5),100%organic fertilizer(T6)on agronomic traits,yield and quality of eggplant and soil nutrients with the experimental material of‘Xinlong Long Eggplant’by the cultivation method of double furrow sowing in solar greenhouse,in order to provide a reference basis for rational fertilization of eggplant in solar greenhouse.The results showed that fertilization could promote the growth of eggplant plants and increase the yield and soil nutrient content of eggplant;25%fertilizer reduction has not significant effect on eggplant growth,yield and soil nutrients compared with conventional fertilization T1.However,fertilizer reduction combined with organic fertilizer T4 treatment could promote eggplant plant production,increase soil nutrient content,and it could significantly increase the yield by 33.74%,increase the content of soluble sugar by 63.1%,decrease the content of nitrate by 35.06%,and increase the content of soluble sugar.As a result,the fertilization of 50%fertilizer+50%organic fertilizer has great effect on eggplant growth,yield improvement and quality improvement.
