Abstract

Abstract:

【Objective】The effects of different levels of NPK on eggplant yield and roots growth as well as rhizosphere microbial numbers and enzyme activities were studied, so as to provide the theoretical basis for the scientific management of NPK (nitrogen, phosphorus and potassium) for the eggplant cultivation by using substrate in solar greenhouse. 【Method】 Substrate trough with sand, slag and mushroom residue (6:3:1, V:V:V) obtained from the previous experiment and drip irrigation integrated with water and fertilizer were used. There were six treatments with fertilization dosage and 100% fertilization dosage (F4) was considered as required by the target yield (fertilization dosage of the target yield = (fertilizer required by target yield - available nutrient content in substrate ) / fertilizer utilization rate), based on the 100% fertilization dosage of F4, the fertilization dosage was reduced by 60% (F1), 40% (F2), 20% (F3) and increased by 20% (F5) and 40% (F6), respectively, and no fertilization treatment was control (CK). The effects of NPK dosage on the yield and roots growth of eggplant as well as rhizosphere microbial numbers and enzyme activity were studied. 【Result】 The eggplant yield was increased firstly and then decreased with the increasing of NPK dosage. Compared with CK, the yield per plant under all treatments increased by 101.1%-212.9%. The eggplant under F3 treatment showed the highest yield per plant and was increased by 212.9% compared with CK. Bacteria were the main microbial in the rhizosphere substrate of eggplants, followed by actinomycetes and fungi. After 90 days of transplanting, with the increasing of NPK dosage, the contents of available NPK in the substrate were increased, the numbers of bacteria, actinomycetes and fungi, the activities of sucrase, catalase and alkaline phosphatase in rhizosphere substrate were increased firstly and then decreased, the values of which were higher under F3 treatment and the urease activity was higher under F4, F5 and F6 than that under other treatments. The root activity, total root length and root surface area of eggplant were increased first and then decreased with the increasing of NPK dosage. Notably, the root activity, total root length and root surface area of eggplant under F2 treatment were increased significantly by 109.2%, 49.2% and 46.5% compared with CK, respectively. There was a significant positive correlation between bacteria number and the enzyme activities in rhizosphere substrate. The urease activity showed extremely significant positive correlation with the contents of available NPK. The activities of catalase and alkaline phosphatase showed significant positive correlation with the contents of available phosphorus and potassium. The number of bacteria, catalase activities showed significant positive correlation with root activity and yield per plant, while urease activity, available phosphorus and potassium content showed significant positive correlation with root activity and yield. The root activity showed extremely significant positive correlation with yield. 【Conclusion】 In summary, the optimal fertilizer dosage for the eggplant cultivation using the mixture of sand, slag and mushroom residue in winter-spring crop in solar greenhouse was N 180.6 kg·hm^-2, P₂O₅ 212.1 kg·hm^-2and K₂O 434.9 kg·hm^-2, which was important to increase the yield of eggplants, root activity, rhizosphere microbial numbers and enzyme activity, and could provide a good micro ecological environment for eggplant growth.
