Embodiment

[0018] 1Materials and methods

[0019] 1.1 Test materials

[0020] The tested soil was fluvo-aquic soil, which was taken from farmland near the Chengdu campus of Sichuan Agricultural University. No cadmium was detected.

[0021] In March 2017, the collected seeds of Solanum fragrans offspring and ungrafted Solanum fragrans seeds grafted from the same plant from the root, from the different plant from the root and from the wild potato rootstock grafted were sown on the farm of the Chengdu campus of Sichuan Agricultural University. In farmland, transplant 2-3 true leaves when they are unfolded.

[0022] 1.2 Pot experiment

[0023] In March 2017, after taking the soil, it was air-dried, crushed, and passed through a 5mm sieve. Weighed 3.0kg into a 15×18cm (height×diameter) plastic basin, and added analytically pure CdCl 2 ·2.5H 2 O solution, make the cadmium concentration in the soil 10mg / kg, and mix it thoroughly with the soil to maintain 80% of the soil field water holding capacity, and...

Abstract

The invention provides a method of mixed planting of grafted progeny of Solanum photeinocarpum Nakamura et odashima for increasing cadmium accumulation of the Solanum photeinocarpum Nakamura et odashima, and belongs to the technical field of application of hyperaccumulators to remediation of heavy metal pollution of soil. According to the mixed planting method, the grafted progeny of the Solanum photeinocarpum Nakamura et odashima obtained from wild potato rootstock and the Solanum photeinocarpum Nakamura et odashima by scion grafting is subjected to mixed planting with non-grafted Solanum photeinocarpum Nakamura et odashima. Different grafted progeny of the Solanum photeinocarpum Nakamura et odashima is selected for mixed planting with the non-grafted Solanum photeinocarpum Nakamura et odashima, the influence of the different grafted progeny of the Solanum photeinocarpum Nakamura et odashima subjected to mixed planting on cadmium accumulation under the condition of cadmium stress is researched, results prove that the effects on the cadmium accumulation characteristic of the Solanum photeinocarpum Nakamura et odashima are completely different by mixed planting of the different grafted progeny of Solanum photeinocarpum Nakamura et odashima, when the grafted progeny of the Solanum photeinocarpum Nakamura et odashima obtained by grafting of the mild potato taken as rootstock and the Solanum photeinocarpum Nakamura et odashima as scion is subjected to mixed planting with the non-grafted Solanum photeinocarpum Nakamura et odashima, cadmium accumulation of the Solanum photeinocarpum Nakamura et odashima can be increased to the greatest extent, and efficient cadmium repair capacity is shown.

Description

Technical field [0001] The invention belongs to the technical field of soil heavy metal pollution remediation, and specifically relates to a method for increasing the accumulation of cadmium on the mixed seed of the grafted offspring of Solanum fragrans. Background technique [0002] Heavy metal pollution spreads to many parts of the world, causing serious losses to agricultural soil and crops in many countries and regions. As one of the most toxic heavy metal elements, cadmium is a non-essential element for plant growth, and its harm is extremely serious. Cd polluted cultivated land in my country reaches 1.3×10 4 hm2, involving 25 regions in 11 provinces and cities, far exceeds other soil heavy metal elements. Cadmium is extremely harmful to plant and human health. At present, the treatment of cadmium-contaminated soil has attracted widespread attention at home and abroad, but the large-scale popularization and application of traditional contaminated soil remediation methods ha...
