Under the thinking of “sharing economy”, Wish Magic wants to create a platform called “shared time bank”, so that users of the platform can store their free time in the “shared time bank” platform in advance. Then, according to the precise docking of products and services as well as supply and demand, Wish Magic also carries out the “wishing tree hole” platform to effectively interact with users according to the latest news and wish list released by users, and regularly goes to poor areas to carry out relevant poverty alleviation activities, so as to provide education support for local people with educational needs and truly play the role of targeted poverty alleviation. In addition, in today’s situation of prevailing pressure, Wish Magic will also create a “spitting tree hole” platform to provide a space for everyone to spit and vent their negative energy, and provide advice for everyone in work, study, love or marriage and other aspects, and help to solve practical problems. The combination of these three platforms enable people to arrange their time reasonably, make effective use of resources, and help people improve their work efficiency and quality of life, so as to create greater economic and social benefits.

Cadmium (Cd) is easily enriched in rice, resulting in an excessive Cd content in the grain, which seriously threatens human health. Manganese (Mn) is an essential element of plants. In a field experiment on Cd-contaminated acid soils, we investigated the effectiveness and mechanism of Mn in minimizing Cd accumulation in rice via foliar spraying using 0.1%, 0.3%, and 0.5% nano-MnO 2 solutions at an early stage of heading. Compared with a control treatment, foliar spraying effectively reduced the Cd content of rice leaves, husks, and brown rice; increased the Mn content of all rice organs; but had no effect on rice yield. Foliar application of nano-MnO 2 alleviated the plant stress induced by Cd by improving leaf photosynthesis, inhibiting lipid peroxidation, and increasing the content of the oxidative stress protein kinase. In addition, foliar application of nano-MnO 2 limited the absorption of Cd by roots by increasing the content of iron-manganese plaque on the surfaces of rice roots and strengthening its adsorption/co-precipitation of Cd. Therefore, foliar application of nano-MnO 2 during the early stages of rice heading is an effective measure to increase the Mn content and reduce the Cd content of brown rice.
