The invention relates to an ecological air purification system having a case body, an air outlet, a fan and plants. The case body is dual-layer structured having an inner chamber, an outer chamber, and a nutrient solution container, the nutrient solution container is fixed at the upper part of the inner chamber where plant culturing medium is arranged; the outer chamber is an air circulation pathway set outside having a circulation chamber, sterilizing chamber, and an exhausting chamber, a fan is set in the exhausting chamber, the air outlet is arranged at the side wall of the exhausting chamber. The present invention discloses a method for purifying air by the purification method. The invention can purify air by making use of the leaf part of plants, and also can give full play to abilities of the plants and greatly improve the ability of plants to treat toxic substances, thereby changing the impression that the efficiency of plants purifying air is comparatively low. The invention has advantages such as high air purifying efficiency, littler pollution, and convenient maintenance.

The invention belongs to the technical field of potato cultivation, and discloses an application of a biodegradable weeding mulching film in potato cultivation. The mulching film comprises the following components in percentage by mass: 70-97% of biodegradable resin A and 3-30% of biodegradable herbicide master batches, wherein the biodegradable herbicide master batches are prepared by a method comprising the following steps: mixing 10-60% of a herbicide with 0.5-7% of a surfactant A, and performing ultrasonic activation; and mixing 25-75% of biodegradable resin B and 1-10% of a surfactant B at a high speed, and performing extrusion and granulation, thereby obtaining the herbicide master batches, wherein the mass ratio of the surfactant A (the hydrophilic-lipophilic balance value is 7-10) to the surfactant B (the hydrophilic-lipophilic balance value is 3-6) is (1:1)-(1:2). As the biodegradable weeding mulching film is used in potato cultivation, the problems that weeds can grow out from furrow surfaces and environment pollution can be caused by common plastics can be effectively prevented, and the labor cost can be lowered.

The invention discloses conductive ink and a preparation method thereof. The conductive ink comprises the following components in percentage by mass: 40 to 55 percent of flaky silver powder, 5 to 10 percent of sliver-coated copper powder, 30 to 45 percent of organic carrier A, 3 to 5 percent of organic carrier B and 0.1 to 0.2 percent of coupling agent. In the conductive ink and the preparation method thereof, the sliver-coated copper powder is added into the conductive ink of pure silver slurry, and part of sliver powder is replaced by the sliver-coated copper powder so as to reduce the cost of the conductive ink. The sliver-coated metal powder is formed by plating a layer of sliver outside the copper powder, so the sliver-coated metal powder is difficult to oxidize, has high ageing resistance and achieves the effects of reducing the cost and not influencing quality.
