Embodiment 1

[0036] 1. Test plan

[0037] The test site is located in a citrus field that has been planted for many years in Yuanli Village, Qujiang District, Quzhou City.

[0038] Select the effective area in the field and divide it into 8 large areas, which are marked as A1, A2, B1, B2, C1, C2, D1, and D2 respectively. Field ridges are built between large areas and large areas, and drainage ditches are opened beside the ridges. The area of ​​each large area is 24-30m 2 . Each large area corresponds to a treatment, interplant in B1, B2, C1, C2, D1, D2 plots with appropriate size and basically the same growth status of zinc and cadmium super-accumulation, lead-enrichment plant Sedum southeast, completely covering three-thirds of the citrus tree canopy For the soil below the range beyond bis, Sedum sedum seedlings are purchased from professional seedling bases. During the citrus growth period, manual weeding is carried out, flowers are picked according to actual conditions, and the irri...

Abstract

The invention discloses a production-while-repairing method for increasing the production and quality of citrus on polluted soil. and Southeast Sedum interplanting cultivation management, and weeding and irrigation were carried out during the cultivation management period; during the new shoot stage, fruit setting stage and fruit expansion stage of citrus, Ladomexin chemical fertilizer and activator were applied once respectively, a total of three times; Carry out deflowering and cutting of sedum before citrus fruit setting, harvest the upper part of sedum sedum one month after cutting, and harvest citrus after the citrus is fully mature. The invention adopts citrus and sedum sedum for interplanting, and uses Ladomexin chemical fertilizer and activator in the critical period of citrus, which not only improves the soil quality of citrus orchards, but also increases the yield of citrus.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a production-while-remediation method for increasing production and maintaining quality of citrus on polluted soil. Background technique [0002] Soil is an important natural resource for human beings to survive. The soil environment directly affects the nutritional quality and quality safety of crops on it, thus affecting the health of animals and humans. With the high-speed industrialization process and agricultural development, the soil pollution in my country is becoming more and more severe, especially in the south. The "National Soil Pollution Survey Bulletin" shows that the total rate of soil exceeding the standard in the country exceeds 16%, of which the rate of soil points exceeding the standard in cultivated land reaches 19.4%. Among all soil pollutants, cadmium has a point exceeding standard rate of 7%, ranking first. Cadmium is highly toxic. Le...
