    摘要:

    采用常规施肥(CK)、中药渣有机肥(OF)和中药渣有机肥耦合高效水溶肥减肥30%(HOF)3 种处理

    Abstract:

    A field experiment was carried out in solar greenhouses with 2 kinds of different soil fertilities to study the effects of coupling of Chinese medicine residue compost and high-efficient water-soluble fertilizer on soil properties and tomato yield. Three fertilization treatments were selected: conventional fertilizer( CK),Chinese medicine residue compost,coupling of Chinese medicine residue compost and high-efficient water-soluble fertilizer with chemical fertilizer nutrient reducing by 30% (HOF).The results showed that HOF treatment increased soil pH by 0.13 ~ 0.15 and significantly reduced electrical conductivity by 328.5 ~ 371.3 μS/cm, nitrate nitrogen by 60.7 ~ 305.0 mg/kg, available P by 42.6 ~ 57.1 mg/kg and available K by 179.4 ~ 274.1 mg/kg, compared with CK.OF treatment also significantly improved soil chemical properties, but the improvement effect was weaker than HOF treatment.As for soil biological properties,HOF treatment increased bacterial abundance and microbial activity and diversity and decreased fungal abundance 28.5% ~ 36.0%, with HOF treatment more significant than OF treatment.However, OF treatment had inhibitory effect on soil urease, invertase and phosphatase activities.Furthermore, the improvement effect of HOF treatment on comprehensive soil properties of high fertility soil was stronger than that of moderate fertility soil.HOF treatment increased the tomato yield by 9.0% and 13.1% in moderate and high fertility soils relative to CK, respectively, while OF treatment increased by 4.6% and 5.9%, respectively.Correlation and principal component analysis indicated that HOF treatment could reduce soil salt and nutrient content and improve soil biological properties, thus effectively increasing the yield.In addition, balanced reduction of available nutrient input via HOF treatment was beneficial to improve soil properties.This situation was more obvious in high fertility soil.Therefore, coupling of Chinese medicine residue compost and high-efficient water-soluble fertilizer can effectively improve the soil fertility quality in eutrophic greenhouse under the condition of reducing chemical fertilizer nutrient by 30%.
