Abstract:

Soil quality degradation has become a bottleneck restricting the sustainable development of facility agriculture and it is of significance to take appropriate measures to conduct soil improvement activities for the sustainable and healthy development of facility agriculture. A soil improvement experiment in plastic greenhouse was carried out to study the effect of Tuxiangxiang (T1), humic acid (T2), Fuhuosu (T3) and vermicompost (T4) on soil physic-chemical properties, soil salt ion composition, crop yield and quality. The results showed that: (1) compared with CK, all amendments could reduce soil bulk density, increase soil porosity, and slightly adjust the soil pH closer to neutral; among them, T1 and T4 treatments had better effects on soil bulk density and porosity, the soil pH was closer to 7.00 in T3 treatment; (2) compared with CK, all amendments could significantly reduce the amount of soil salt ions and electronic conductivity, the reduction of soil salt ions and electronic conductivity of T3 treatment could reach 68.21% and 75.89%, respectively; (3) compared with CK, all amendments had the effect of yield increase, T3 and T4 treatments had better yield increase effects with 14.37% and 21.01%, respectively; (4) compared with CK, all amendments could significantly improve soluble solid of melon, of which T3 treatment had the best effect, there was no significant difference on the titratable acid of melon among all treatments, the solid acid ratio and vitamin content of melon incresed in some treatments and decreased in others, of which T1 and T3 treatments had higher solid acid ratio of melon, and T3 treatment had significantly higher vitamin content of melon than others, reaching 146.21 mg/kg. In general, T3 treatment has the best effect in terms of soil improvement, soil salt reduction, crop quality improvement and yield increase.

Key words: amendment, plastic greenhouse, soil salt, quality, yield, melon
