Conifer growth stimulation and forest management
专利汇可以提供Conifer growth stimulation and forest management专利检索，专利查询，专利分析的服务。并且Conifer growth is stimulated by topical and/or foliar application of biuret which achieves direct contact of biuret with the conifer roots and/or foliage respectively. Foliar application is more effective on older trees. Optionally, undesired vegetation, such as ferns and broad-leaf plants, is controlled and conifer growth is promoted by application of biuret-containing solutions to the foliage of all plants. Novel compositions particularly useful in these methods contain biuret and a surfactant and/or polar solvent other than water sufficient to facilitate foliage wetting.，下面是Conifer growth stimulation and forest management专利的具体信息内容。
I claim:1. A method for promoting the growth of conifers which comprises applying to said conifers an amount of biuret sufficient to promote the growth of said conifers.2. The method defined in claim 1 wherein said biuret is applied to the foliage of said conifers.3. The method defined in claim 1 wherein said biuret is applied to the foliage of said conifers as a liquid solution or dispersion.4. The method defined in claim 1 wherein said biuret is applied to said conifers as an aqueous solution comprising a member selected from the group consisting of surfactants, polar solvents other than water, and combinations thereof.5. The method defined in claim 1 wherein said biuret is applied to said conifers at a rate corresponding to at least about 0.1 pound of biuret per acre.6. The method defined in claim 1 wherein said biuret is applied to said conifers at a rate corresponding to at least about 1 pound of biuret per acre.7. The method defined in claim 1 wherein said biuret is applied to said conifers at a rate corresponding to at least about 10 pounds of biuret per acre.8. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition comprising a plant nutrient in addition to said biuret.9. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition further comprising a compound selected from the group consisting of urea, ammonium and potassium sulfates, nitrates, phosphates, and combinations thereof.10. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition which further comprises urea.11. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition which further comprises urea, and the biuret/urea weight ratio is at least about 0.02.12. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition which further comprises urea, and the biuret/urea weight ratio is at least about 0.05.13. The method defined in claim 1 wherein said biuret is applied to said conifers in a composition which further comprises urea, and the biuret/urea weight ratio is at least about 0.1.14. The method defined in claim 1 wherein said biuret is applied to said conifers at a rate corresponding to about 0.1 to about 20 pounds per acre, and said conifers are about five years old or less.15. The method defined in claim 1 wherein said conifers comprise commercial timber trees of the family Pinaceae.16. The method defined in claim 1 wherein said conifers comprise trees selected from the group consisting of the genra Abies, Sequoia, Picea, Pinus, Pseudotsuga, Tsuga, and combinations thereof.17. The method of claim 1 wherein said conifers are selected from the group consisting of Grand fir, Red fir, Pony fir, hemlock, spruce, cedar, loblolly pine, Ponderosa pine, lodgepole pine, white pine, sequoia sempervirens, and combinations thereof.18. The method defined in claim 1 wherein said biuret is applied to the foliage of said conifers as an aqueous solution in which the biuret/urea weight ratio is at least about 1.19. The method defined in claim 1 wherein said biuret is applied to the foliage of said conifers as an aqueous solution comprising at least about 5 weight percent urea in which the biuret/urea weight ratio is at least 0.05.20. The method defined in claim 1 wherein said conifers are growing in the presence of non-coniferous plants, and said biuret is foliarly applied to said conifers and said non-coniferous plants at a dosage rate sufficient to inhibit the growth of said non-coniferous plants.
