The invention discloses a method for indoor quick recognition of resistance of wheat to wheat root rot Ustilago esculenta black embryo disease. The method comprises the following steps: firstly, performing surface sterilization on wheat seeds, and performing seedling culture on the sterilized wheat seeds; preparing a wheat root rot boehmeria sorokiniana spore suspension, so as to obtain a spore suspension; shaking up the spore suspension liquid, spraying the spore suspension liquid onto wheat leaves with one leaf and one core for inoculation culture, and recording the percentage of the scab area of the first leaf of the wheat seedling in the total leaf area on the tenth day of inoculation culture, namely the scab area percentage; and calculating the wheat black embryo rate according to theequation, and evaluating the resistance of the wheat to the wheat root rot Umbilical Verticillium dahliae black embryo disease by utilizing the black embryo rate. Compared with an existing field recognition method, the recognition method has the advantages that the recognition time is shortened, the recognition link is simplified, the recognition efficiency is greatly improved, and the accuracy and reliability of the recognition result are improved.

The invention discloses a preparation method of an organic watermelon continuous cropping high-yield composite bacterial fertilizer, relating to the organic watermelon continuous cropping high-yield cultivation technology. The raw materials include turf, biogas residue, plant ash, enzyme microorganism, boron-magnesium fertilizer, zinc sulfate, ammonium molybdate, hydnocarpus anthelmintica, pomegranate root peel, tripterygium wilfordii, ningnanmycin, bacillus subtilis, verticillium chlamydosporium and choline chloride. The method disclosed by the invention has the beneficial effects that through the synergistic effect of the raw materials, the problems of serious watermelon growth obstacle such as nutrient (especially organic matters, trace elements and the like) lack and imbalance, frequent occurrence of pest and disease damage and germ damage, drop of quality and output and the like caused by continuous cropping of watermelons can be fundamentally solved. Meanwhile, by adopting multiple beneficial bactericides and Chinese herbal medicine organic insecticides instead of high-toxicity high-persistent pesticides, the harm to physical health and environment is avoided and reduced, and organic watermelons which are really green and pollution-free and have pure taste and high sweetness are produced. By adopting the scientific formula, the continuous cropping diseases of watermelons can be effectively treated, and high quality and high output still can be obtained through continuous cropping of watermelons.

The invention discloses a peanut continuous cropping high-yielding agent, relating to a peanut continuous cropping disease-resistant high-yielding technology. The peanut continuous cropping high-yielding agent comprises the following components in percentage by weight: 30-40 percent of humic acid, 25-35 percent of grass carbon, 10-20 percent of calcium sulfate, 5-8 percent of magnesium sulfate, 3-5 percent of zinc sulfate, 3-5 percent of manganese sulfate, 5-8 percent of ferrous sulfate, 3-5 percent of borax, 1-2 percent of rare earth nitrate, 0.1-1.5 percent of ammonium molybdate, 0.5-3 percent of Chinese azalea flower, 0.5-3 percent of marigold, 0.3-1.5 percent of ningnanmycin (8 percent in concentration), 1-2 percent of verticillium chlamydosporium and 1-2 percent of bacillus subtilis. The peanut continuous cropping high-yielding agent has the advantages that by comprehensively applying organic matters, cellulose, humic acid, trace elements, soil conditioners and root nodule growth nitrogen fixation agents, soil is improved, nutrients are balanced, the fertilizer effect is improved, the soil environment is improved, and a good soil-fertilizer condition is provided for the healthy growth of peanuts. Meanwhile, by applying the Chinese azalea flower and the marigold serving organic insecticides, the ningnanmycin serving as a bactericide, the verticillium chlamydosporium agent serving as a buster of threadworms and the bacillus subtilis serving as a microbial agent, insect pests are killed, diseases are eliminated, a growing and breeding environment for soil beneficial bacteria is established, the flora advantage of the soil is improved, peanut plants are robust, and high continuous cropping yield is achieved.
