The invention relates to organic carbon suspension liquid compound fertilizer and a preparation method of the organic carbon suspension liquid compound fertilizer. The organic carbon suspension liquid compound fertilizer comprises, by weight, 18.1-26.5 parts of organic carbon, 0.4-7.2 parts of nutrient substances, 10-12.5 parts of suspending agents and 25.0-33.0 parts of water. The organic carbon suspension liquid compound fertilizer can resolve the unbalanced fertilizer application state of carbon hunger of crops, is complete in nutrient, promotes better growth of the root systems of crops, improves the yield and quality of crops, effectively prevents the carbon hunger symptom of crops, and improves the adverse resistance of crops such as cold resistance, drought resistance and disease resistance.

The invention discloses a composite wheat seed soaking agent as well as a preparation method, a usage method and an application thereof and belongs to the field of wheat seed soaking agents. The composite wheat seed soaking agent mainly comprises uniconazole, bachmedesh and diphenylurea. The invention further discloses the preparation method, the usage method and the application of the composite wheat seed soaking agent. The uniconazole, the bachmedesh and the diphenylurea are subjected to ternary compounding, then a compound is diluted with a corn pollen liquid and used for processing wheat seeds, so that the negative effects caused by usage of single component can be eliminated more effectively, the obvious synergistic interaction function is realized through compatibility of four components, germinated seedlings are short and strong, root systems are developed, the lodging resistance is enhanced, and stress resistance such as insect resistance, drought resistance, salt tolerance and the like is remarkably improved. With the adoption of the composite wheat seed soaking agent for processing the wheat seeds, the wheat planting range can be broadened, and effects of production increase, yield stabilization and the like are realized.

The invention discloses a method for screening a drought-resistant and saline-alkaline-tolerant cotton variety, and relates to the technical field of agriculture. The method for screening the drought-resistant and saline-alkaline-tolerant cotton variety comprises the steps of manufacturing artificial saline-alkali land, preparing cotton seeds, cultivating cotton, detecting drought tolerance of thecotton and detecting the alkali tolerance of the cotton; the cotton variety with the highest drought resistance and highest saline-alkaline tolerance is obtained through actual cultivation, the defects of wrong selection and missing selection can be overcome, and seed selection is more convincing.

The invention discloses a drought-resistant related SSR sequence derived from abnormal cotton and application thereof. The invention provides application of a specific DNA fragment or related biomaterials thereof in cultivation of drought-resistant cotton varieties or strains or improvement of the drought resistance of cotton. The specific DNA fragment is a fragment located on chromosome 5 of abnormal cotton and at least containing a sequence from an SSR molecular marker JAAS6365 (SEQ ID No. 1) to an SSR molecular marker JAAS5604 (SEQ ID No. 2). The related biomaterials are a vector, an expression cassette, recombinant bacteria or transgenic cell line containing the specific DNA fragment. The chromosome fragment provided by the invention has important application value in drought-resistantcotton breeding, and at the same time the SSR molecular marker developed by the invention provides a molecular basis for cultivation of drought-resistant cotton varieties that can be applied to production.

The invention discloses a mountain heightening measure method and construction. The method involves a travel mountain and a national defense mountain, and is characterized in that one mountain is molded; the water and soil loss, the drought resistance and the stimulation treatment are added to the agriculture; along with development of high-technology weapons, the thickness of the national defense mountain is insufficient, so that the heightening protection is performed for the national defense mountain to improve the shell resistance; the mountain heightening measure method is a future mountain heightening protection measure; mountain skin soil is stripped off; after reinforced concrete is used for reinforcement, the stripped soil mountain skin covers the reinforced concrete; the reinforced concrete heightening measure is performed for the mountain; the reinforced concrete protection advantage is reinforced; and the reinforced concrete mountain confrontation strength is exerted.

The invention provides a research method for increasing the oxidation resistance of Ilex verticillata. The method includes: selecting the biennial cuttage seedlings of two Ilex verticillata varieties,and performing acclimation in a greenhouse for 2 months; selecting 18 cuttage seedlings of each of the two varieties, separating each variety into two groups, spraying melatonin to one group, and spraying equal-amount clean water to the other group; performing identical drought stress treatment at the same time; collecting fresh leaves immediately after the treatment, on the seventh day after thetreatment and on the thirtieth day after the treatment, quickly freezing the collected leaves in liquid nitrogen, and preserving the frozen leaves in refrigerator of ultralow temperature of minus 80DEG C; measuring superoxide dismutase and peroxidase activity and malondialdehyde content. The research method has the advantages that by applying external melatonin to perform treatment, the influence of the melatonin on the oxidation resistance of the Ilex verticillata cuttage seedlings under drought stress is comparatively analyzed; the research results can lay a foundation for the research ofthe Ilex verticillata physiological mechanism responding to the drought stress and measures for increasing the drought resistance of the Ilex verticillata and the popularization of the Ilex verticillata in drought regions.
