Provided is a solid fuel which is suitable for thermal power generation and uses the residue left after collecting beneficial seeds, grains, or bulbs. The solid fuel is obtained by thermal compression molding of a composition comprising, by dry weight, 70 wt% or more of dried Arundo donax, Leucaena leucocephala, Saccharum officinarum, Manihot esculenta, straw, seaweed, seagrass or algae.

The invention discloses a treatment method for slowing gully erosion, and belongs to the technical field of water and soil conservation. The method comprises four parts, namely gully selection, gully head treatment, gully bottom treatment and gully head wall treatment. In the gully, the slope of the left gully wall or the gully wall is less than or equal to 45 degrees and the height of the gully head wall is less than or equal to 5 meters; jatropha curcas and dodonaea viscose are planted above the gully head to form an inverted U-shaped buffer plant hedge belt above the gully head; timber piles are embedded into the plant hedge belt crookedly; the width of an inverted U-shaped opening is equal to that of the gully head or the width is 1 to 1.5 meters; the top of the inverted U-shaped curve is 3 to 5 meters away from the gully head; leucaena glauca are planted on the gully bottom to form a U-shaped buffer plant hedge belt on the gully bottom; the bottom of the U-shaped curve is 3 to 5 meters away from the gully head; lianas are planted and the timer piles are embedded into the soil between the buffer plant hedge belts above the gully head and the gully bottom; and the two ends of iron wires are respectively fixed to the timber piles at the gully bottom and above the gully head and are attached to the ground surface. In the method, key points of slowing the gully erosion are grasped; and the treatment configuration mode has high comprehensiveness, scientificity and reasonability.

The invention discloses a method for extracting total RNA from leucaena leucocephala leaf tissues. During a leucaena leucocephala leaf tissue total RNA extraction process, 0.9-1.0g of crosslinked polyvinyl pyrrolidone (PVPP) powder is added, such that polysaccharides, proteins, and transparent viscous insoluble substances are comprehensively removed. With the method, the OD260 / OD280 ratio of the extracted leucaena leucocephala leaf tissue total RNA is 1.8-2.0. The obtained RNA has high purity and high yield. Also, when the obtained RNA extract liquid is detected by using 1.5% agarose gel denaturation electrophoresis, the obtained strip is clear, RNA integrity is good, and the extracted RNA can be completely used in leucaena leucocephala molecular biology researches. The method has important significance in analyzing leucaena leucocephala gene expression and regulation, gene cloning and function identification, and molecular marker-assisted breeding. The method has high practicality, and good promotion ad application value.

The invention provides a method for biologically preventing and controlling leucaena glauca diffusion. The method includes the steps that multiple leucaena glauca seeds with leucaena glauca bean weevil eggs attached to the surfaces are made into an egg release seed bag, and then the egg release seed bag is placed in a low-temperature environment to be refrigerated to be used in the biological prevention and control release process; and / or multiple leucaena glauca seeds carrying leucaena glauca bean weevil larvae are made into a larva release seed bag, and then the larva release seed bag is placed in a low-temperature environment to be refrigerated to be used in the biological prevention and control release process; and / or multiple imagoes of first-filial-generation leucaena glauca bean weevil are made into an imago release bag, and then the imago release bag is placed in a low-temperature environment to be refrigerated to be used in the biological prevention and control release process. According to the method for biologically preventing and controlling leucaena glauca diffusion, the problems that the physical and mechanical felling is poor in effect and high in cost can be solved, cost is low, the acting effect is obvious, and the control effect can be continuously exerted.

The invention provides a novel rock-soil body side slope ecological stabilizer which is used for solving the problem of water and soil losses caused by rain wash on a side slope soil body, playing a role in corrosion resistance and also achieving the aim of ecological restoration of an exposed side slope of a rock body. The novel rock-soil body side slope ecological restoration and corrosion resistance stabilizer is characterized by being prepared by anionic polyacrylamide, potassium chloride, ethyl acrylic ester, epoxy acrylic ester and water according to the proportion, the blending mass ratio under the condition of the room temperature is 0.5: 2: 0.5: 0.5: 96.5 in sequence, the blending proportion of the stabilizer and the soil body makes the moisture content of the soil body after blending be controlled between the best moisture content of the soil body and the plastic limit of the soil body, then grass seeds and shrubs are added to be blended, the mixture is aired to be the moisture content state under which wet spraying operation requirement is met, the size of the caked soil body meets the operation requirement of a selected wet spraying machine, finally the pump-type wet spraying machine is utilized for wet spraying, the grass seeds are formed by blending ryegrass, dodonaea viscosa and Chinese pennisetum according to the mass ratio of 1: 1: 1, and the shrubs are formed by blending magnolia multiflora, leucaena leucocephala and pyracantha fortuneana according to the mass ratio of 1: 1: 1.

The invention discloses a feed for rabbits using Leucaena microphylla as raw material, which comprises the following raw materials: pretreated Leucaena microfolia, corn flour, wheat bran, soybean meal, bone meal, inorganic salt, vitamins and amino acid additives, carboxymethyl shell polysaccharide solution mixture and probiotics; the preparation method of the rabbit feed comprises the following steps: (1) pretreatment of Leucaena microphylla: chop the tender stems and leaves of Leucaena microphylla into small sections, soak them in warm water, Freeze in an environment of ‑20°C, put it into a fermentation container, control the stacking thickness of Leucaena lobata, mix in extracellular enzymes, and pass in N 2 / C0 2 The mixed gas is fermented at 23-30° C. for 20-35 hours, dried and dehydrated to constant weight to obtain pretreated Leucaena lobata; (2) crushing and granulating; (3) coating treatment. The invention can improve the palatability of leguminous herbage, and provides a rabbit feed which effectively reduces feeding cost, has comprehensive nutritional value, is easy to absorb, and improves disease resistance.
