Chromobacterium suttsuga sp. nov., a new species of the genus Chromobacterium which possesses insecticidal activity, is described. The invention also relates to insecticidally-active metabolites obtained from the strain and to insecticidal compositions comprising cultures of the strain and/or supernatants, filtrates, and extracts obtained from the strain, and use thereof to control insect pests.

The invention discloses a method for intercropping a rice field with lobsters. The method comprises the steps as follows: preparation of the rice field, disinfection and fertilization of the rice field, planting of aquatic plants, snail throwing, seedling stocking, rice transplantation and daily management. The survival rate and yield of lobsters are greatly increased and the method has good economic benefit.

A shield for protecting a plant having; a stem having an upper end and a lower end; a first plurality of sticks having a proximal end and a distal end; and a pad associated with the upper end of the stem, the pad having a second plurality of holes distributed all around the pad and oriented at various angles in relation to a horizontal plane, the holes being configured for removably receiving the proximal ends of the entire first plurality of sticks or a portion thereof and securing the same therein through friction-based insertion; the second plurality of holes distribution and orientation allowing the formation of a support structure for a protective cover in which the entire first plurality of sticks or a portion thereof extends in a circular arrangement above the plant at an angle conforming to the shape or size of the plant.

The invention discloses a synergist for improving crop resistance and fertilizer absorption capacity. The synergist includes the following components by weight: 20-30 parts of an oyster shell powder, 20-30 parts of a water chestnut skin powder, 10-20 parts of a chinaberry bark powder, 10-20 parts of a magnetic material, 10-20 parts of an illite powder, 5-10 parts of a shiitake mushroom polysaccharide extract. The synergist can, on one hand, improve the resistance of crops, especially reducing the pests and diseases significantly, improving waterlogging and drought resistance; and, on the other hand, greatly reduce the use of fertilizers, especially nitrogen fertilizers, preventing soil compaction. It can also significantly increase the content of active polysaccharides, especially β-glucan in crops. In addition, the raw materials are readily available, the cost is low, and there are significant economic benefits.

The invention discloses a bio-based insect trapping plate. The bio-based insect trapping plate is composed of a bio-based insect trapping plate substrate, an insect sticking glue layer attached to atleast one side of the bio-based insect trapping plate substrate and release paper covering the insect sticking glue layer, wherein the bio-based insect trapping plate substrate comprises thermoplasticpolyethylene resin, papermaking waste which is not less than 20% of the weight of the thermoplastic polyethylene resin and an effective amount of an auxiliary agent. A preparation method of the bio-based insect trapping plate comprises the following steps: uniformly mixing all the components, adding the mixture into a stock bin of a double-screw extruder, and carrying out extruding and granulating to obtain master batches; and adding the master batches into a sheet extruder, extruding sheets and then slitting the sheets to prepare the bio-based insect trapping plate substrate; and spraying insect sticking glue on the two sides of the substrate, and covering the outside of the insect sticking glue layer with the release paper to prepare the bio-based insect trapping plate. According to thebio-based insect trapping plate, the papermaking waste is added into the thermoplastic polyethylene resin, so that the cost of the bio-based insect trapping plate is greatly reduced, the insect trapping effect and the mechanical property of the bio-based insect trapping plate are superior to those of a traditional PP and PVC insect trapping plate, and the use requirements can be met.

The invention provides an interplanting culture method of akebia trifoliata and pinellia ternate. The method comprises the steps of (1) transplanting raised akebia trifoliata seedlings onto a shed frame; (2) arranging a three-dimensional seedling raising frame under the shed frame, and spreading pinellia ternate tubers onto culture media after the culture media are thoroughly watered, wherein a plurality of planting grooves in the three-dimensional seedling raising frame are provided with the culture media respectively; (3) spraying a layer of slow-release fertilizer onto the culture media after pinellia ternate seedlings emerge, thoroughly performing watering when the water content of the culture media is lowered to 20% or below, and performing fertilization and water management in the later period; (4) harvesting pinellia ternate in July or August, continuing to plant pinellia ternate tubers into the planting grooves in middle and late September, and harvesting pinellia ternate fromlate January to early March. In the culture method, the plant diseases and pests of akebia trifoliata are reduced, the management is extensive, and the use amount of pesticide is smaller than that ofwoody climbers, so that the influence on the growth of pinellia ternate is small; since pinellia ternate is a shade-resistant medicinal material, the planting grooves can be formed in the three-dimensional planting frame, and the output of the unit land area is increased.
