Abstract:
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.
