The invention discloses the application of fluridone in promoting rice tiller bud differentiation and regenerating rice planting. The fluridone can be used to promote the growth of regenerated rice and the differentiation of rice tiller buds, has a regulating effect on the growth of regenerated rice, has little environmental pollution, can effectively reduce the occurrence of rice diseases and insect pests, and can be widely used in different regions. , In the planting of regenerated rice of different rice varieties, it has obvious effect of increasing panicle and yield.

The invention provides a herbicide composition for a cotton field, a preparation thereof, and application and an application method of of the composition and the preparation, and relates to the technical field of herbicides. The herbicide composition for the cotton field comprises a herbicide A and a herbicide B. The herbicide A is fluridone, and the herbicide B is selected from at least one of a long-chain fatty acid synthesis inhibitor, a microtubule assembly inhibitor, a mitotic inhibitor, a lipid synthesis inhibitor, a photosynthetic system IIA site inhibitor and a fatty acid thioesterase inhibitor. Through mutual synergistic interaction of the herbicide A and the herbicide B, after the herbicide composition preparation is applied to the cotton field, the weed control effect is high, the herbicide controlling spectrum is wide, the safety is good, the selectivity coefficient between cotton and weeds is obviously higher than that of a single herbicide, the yield increasing effect is obvious, meanwhile, the generation of resistance of the single herbicide is delayed, the cost is low, and the herbicide composition preparation is easy to popularize.

The invention relates to a cultivation method for improving the yield and the quality of Cistanche deserticola. Annual Haloxylon ammodendron saplings are selected, and are planted in desertified loess in spring or autumn according to a planting density of 0.15-0.52 plant / m<2>, humus soil is applied according to a ratio of 1000-2000 g / plant, the planted samplings are timely watered to ensure the survival rate, inoculation with a Cistanche deserticola seed mixture is carried out after the Haloxylon ammodendro saplings grow to about 1.5 m, the humus soil is applied again according to a ratio of 500-2000 g / plant, the inoculation time is March to May Or October to December every year, the Cistanche deserticola seed mixture comprises Cistanche deserticola seeds subjected to seed soaking treatment in a seed soaking solution, sucrose, L-tyrosine, L-phenylalanine and mint powder, the seed soaking solution is a 3-5 mg / L fluridone solution, the seed soaking treatment time is 12-36 h, and the Cistanche deserticola seeds subjected to seed soaking treatment are obtained through drying the soaked seeds in the shade. The cultivation method has the following advantages: the inoculation process of the Cistanche deserticola seeds is simple, and can effectively promote the germination of the Cistanche deserticola seeds and effectively improve the yield of the Cistanche deserticola planted in the desertified loess; and the composition of the Cistanche deserticola seed mixture can be screened to obviously improve the content of effective components comprising echinacoside and verbascoside in the artificially planted Cistanche deserticola, improve the quality of the artificially planted Cistanche deserticola and effectively enhance the drug effects and the economic benefits of the artificially planted Cistanche deserticola.

The invention relates to a seedling growing method of Wushan epimedium, and belongs to the technical field of traditional Chinese herbal cultivation. The method comprises the following steps: step one, collecting and pre-treating Wushan epimedium seeds; step two, subjecting the processed Wushan epimedium seeds to a temperature-variable stratification treatment, wherein in the temperature-variable stratification treatment, the Wushan epimedium seeds are placed at a temperature of 10 DEG C for 12 hours and then placed at a temperature of 20 DEG C for 12 hours, and the two steps are carried out alternately; step three, soaking the Wushan epimedium seeds in a solution containing fluridone; step four, subjecting the Wushan epimedium seeds to a low-temperature (3-6 DEG C) stratification treatment. Through the method, the germination rate, germination potential, and germination index of Wushan epimedium seeds are all prominently improved, and the average germination time is obviously shortened. The operation is simple, the controllability is strong, the Wushan epimedium seed dormancy can be awaken efficiently, and normal seedlings can be obtained.
