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 provides jatropha curcas L. ribosome-inactivating protein and a preparation method thereof. The jatropha curcas L. ribosome-inactivating protein is separated and purified from cotyledon and / or endosperm of jatropha curcas L. seedlings which are generated by jatropha curcas L. seeds germinating for 4 to 49 days, relative molecular weight is 31.398kDa, an isoelectric point is 7.12, and a sequence of amino acid residue of an N-terminal of the ribosome-inactivating protein is shown as SEQ ID No: 1 in a sequence table. The invention further provides application of the jatropha curcas L. ribosome-inactivating protein in preparing medicines for treating tumor. The jatropha curcas L. ribosome-inactivating protein has an obvious anti-proliferative effect on human osteosarcoma U20S, human non-small cell lung cancer A549, human non-small cell lung cancer H1975 and human colon cancer HCT116; an in-vitro proliferation inhibition effect of the jatropha curcas L. ribosome-inactivating protein on the human osteosarcoma U20S is superior to that of Curcin and taxol; furthermore, toxicity to human normal kidney cells is lower.

The invention discloses a compound base fertilizer for jatropha curcas, which comprises nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, and also comprises the following components in percentage by weight: 0.1 to 1.0 percent of amino acid chelated rare earth, 15 to 30 percent of nitro humic acid, 0.55 percent of ferrous sulfate, 0.4 percent of disodium tetraborate, 2 percent ofmanganese sulfate, 0.5 percent of copper sulfate, 0.25 percent of zinc sulfate and 0.2 percent of ammonium heptamolybdate, wherein the total N content of the compound base fertilizer is 11 to 13 percent, the effective P2O5 content is 5.5 to 6.5 percent and the K2O content is 6.5 to 7.5 percent. The invention also discloses a flower and fruit promoting compound additional fertilizer and a fruit swelling additional fertilizer for the jatropha curcas. The corresponding compound base fertilizer or the additional fertilizer is selected according to different growth periods of different jatropha curcas and applied in large area so as to realize spring transplant and autumn fruiting of the current year and high yield period in three years, each mu produces over 750 kilograms of dry fruits, the oil content of seeds is over 41 percent, and the oil content of kernels reaches 65 percent.

The invention discloses a compound pickling corrosion inhibitor of jatropha curcas cake extract and a preparation method thereof, which belong to the technical field of corrosion inhibitors. The present invention optimizes the process of extracting acid corrosion inhibitor from jatropha curcas cake, removes toxic protein and phorbol ester, overcomes the problem that the acid corrosion inhibitor extracted from jatropha curcas cake is toxic, and uses pomelo peel extract and leprosy The tree cake extract has a synergistic effect, high corrosion inhibition efficiency, strong adaptability, and obviously inhibits the corrosion effect of acid on steel and aluminum materials, and more importantly, it has a good corrosion inhibition effect on zinc, zinc and aluminum alloys. The corrosion inhibitor of the invention is safe, harmless, biodegradable, and easy to use, and can be applied to cleaning petrochemical equipment, boilers, and even tap water pipelines, and has good development prospects.
