Effects of different green ecological technology models on tomato growth
In order to make better application of eco-agriculture technology,and select the best planting mode suitable for tomato cultivation,four planting technology modes were set up:"three-zero"planting technology(T1),inline straw bioreactor technology(T2),interplanting and interbreeding technology(T3),interplanting and interbreeding technolo-gy of earthworm on ridge(T4),using conventional cultivation as control(CK).The effects of different green ecologi-cal technology models on tomato growth,quality and yield were compared.The results showed that the total yield of T1 was 24.86％higher than that of CK.The total sugar content,sugar-acid ratio,vitamin C content,soil organic matter,to-tal phosphorus and available phosphorus content were significantly higher than those of other treatments.The sugar-acid ratio of T1 was 12.52％,13.68％and 17.12％higher than that of CK,T2 and T3,respectively.Vitamin C content of T1 was significantly higher than CK,T2,T3 and T4 by 7.97％,65.56％,59.53％and 29.57％,respectively.The content of soil organic matter was 4.59％,17.14％,19.19％and 22.02％higher than CK,T2,T3 and T4,respectively.The content of heavy metals arsenic and cadmium in soil decreased significantly.According to the comprehensive judgment,T1 has the best planting effect and can be used as the best planting mode of facility tomato for promotion and application in pro-duction.
