Effects of different fertilization schemes on the growth,development,and fruit quality of indoor planted tomatoes
To investigate the effects of different fertilization schemes on the growth,development,and fruit quality of indoor planted tomatoes,wild-type tomato Micro Tom was used as the research object,and 8 different fertilization treatments were applied throughout the entire growth cycle.Specifically,it includes root irrigation with clean water(CK),foliar spraying with nutrient solution(T1),foliar spraying with phosphorus fertilizer(T2),foliar spraying with small particle fertilizer(T3),foliar spraying with nutrient solution+phosphorus fertilizer(T4),foliar spraying with nutrient solution+root spraying with small particle fertilizer(T5),foliar spraying with phosphorus fertilizer+root spraying with small particle fertilizer(T6),foliar spraying with nutrient solution+foliar spraying with phosphorus fertilizer+root spraying with small particle fertilizer(T7).The results showed that compared with the control group,T3,T5,and T6 could significantly promote the growth of tomato plant height,stem diameter,and second lateral branch;T3 and T7 treatments can promote the synthesis of chlorophyll;T5 treatment can significantly promote tomato flowering,fruit size,and seed number;T3 treatment can significantly increase the number of tomato fruits;The soluble sugar content of T3 and T7 was higher than that of T5 and T6;The vitamin C content of T5 and T6 was higher than that of T3 and T7.In summary,applying only small particles,nutrient solution+small particles,phosphorus fertilizer+small particles,and nutrient solution+phosphorus fertilizer+small particles can significantly promote the growth,yield,and quality of tomatoes.Among them,the fertilization scheme that only applies small particles costs less than other treatment groups,and can reduce the harm of fertilizer to the environment,making it the best fertilization scheme.
