The invention relates to a cold-resistant acclimation method for kandelia candel seedling pot plants planted at a high latitude. The method successively comprises the following steps that firstly, kandelia candel hypocotyls developing well are collected, soaked by using seawater and transplanted to a planting field as soon as possible; secondly, flower pots are placed on the planting field and then filled with planting soil; then, the kandelia candel hypocotyls are inserted and planted in the flower pots; finally, before winter, a greenhouse is built on the planting field, it is guaranteed that tidewater can normally rise and fall to the interior of the greenhouse, and the kandelia candel hypocotyls which are inserted and planted in the flower pots are subjected to high-temperature and low-temperature alternative acclimation cultivation. According to the cold-resistant acclimation method, in the natural mudflat environment, a potting technology is used for seedling raising and acclimation at the same time, the survival rate is increased, and afforestation through kandelia candel is achieved in harsh mudflats; in the seedling raising process in winter, the environmental temperatureof the greenhouse is continuously adjusted, so that seedlings gradually adapt to the cold climate, the adaptive capacity to the lower temperature is improved, and the mangrove forest grows in a high-latitude area with the north latitude of 28-31 degrees.

The present invention relates to a kind of method for producing root tip chromosomes of plants of the genus Lysymus genus, the method comprising the following steps: (1) taking materials: 5 to 7 days after the seeds of Lysymus germinate at a constant temperature, take the white new roots of vigorously growing potted plant Lysymus spp. Put it into a centrifuge tube; (2) place the centrifuge tube with the root tip in a high-pressure container device, and pretreat it with N2O to obtain a new root after pretreatment; (3) dry the new root after pretreatment, and use Carnot’s fixed with liquid to obtain new roots after fixation; (4) the new roots after the fixation were rinsed and dried and then dissociated with glacial acetic acid to obtain new roots after the dissociation; (5) the moisture in the new roots after the dissociation was blotted and placed On the glass slide, make a pressed piece; (6) place the pressed piece under an optical microscope to observe, select the cells with dispersed and clear chromosomes for photography, so as to perform fluorescence in situ hybridization, and finally mark the position of the cover glass with a glass knife, Store the prepared slices in a -80°C refrigerator. The invention is efficient and safe.

The invention belongs to the field of agricultural plant breeding and discloses a method for increasing the hybrid seed production efficiency of self-incompatibility gramineous plants. The method includes the steps of firstly, preparing materials, to be more specific, planting Chinese silvergrass seedlings or rhizomes in pots; secondly, culturing plants, to be more specific, culturing the pot-cultured Chinese silvergrass under 24 DEG C and in light for 16 hours / under 18 DEG C and in darkness for 8 hours, watering once each day until the soil is completely wetted, and supplementing a Hoagland plant nutrient solution three times every week; thirdly, pruning the plants, to be more specific, timely cutting off tillers after flowering each day in the flowering period to promote the plants to constantly growth new tillers and achieve earing and flowering, cutting of the tillers after flowering, and repeating to achieve annual flowering; fourthly, using dark induction to induce inflorescencespikelet to disperse pollen, to be more specific, arranging inflorescence about to enter the vigorous flowering period, and inducing the plants under room temperature in complete darkness for 8-12 hours; fifthly, collecting pollen, to be more specific, shaking the inflorescence to collect the pollen after most spikelet on the inflorescence exposes anther after the dark induction. The method is simple, efficient and beneficial to the efficiency of Chinese silvergrass hybrid breeding and genetic researches.

The invention relates to a potted plant technique based efficient breeding method for salix brachypoda cutting in degraded inland saline marsh wetlands with an aim to mainly solve problems the salix brachypoda cutting in the degraded inland saline marsh wetland is low in survival rate and slow in restoration. The method specifically includes the steps of 1), seed selection and storage; 2), land selection; 3), soil unloading and potting; 4), cutting; 5), hydrologic management; 6), transplantation. The method has the advantages that raw materials are easy to obtain, cost is low, operation is simple and easy to implement, and centralized management is facilitated; ecological laws are obeyed, and environmental adaptabilities of wetland plants are fully considered; restoration of an inland saline-alkali marsh wetland ecosystem is benefited; the survival rate of salix brachypoda can reach more than 97%, and biodiversity of wetlands is increased.

The invention belongs to the technical field of plant breeding methods, and particularly relates to a method for breeding and generation-adding of medicago polymorpha. The method comprises the following steps: the medicago polymorpha is planted in a pot outside a room in October of a current year; the medicago polymorpha is moved into the room and subjected to lighting and heating treatment in the end of December; the medicago polymorpha blooms in January of a next year and is subjected to interspecific crossing, and end growth points are pinched off after pods are born; mature seeds are harvested in March and dried in the sun; the just harvested seeds are subjected to peel cutting in April, planted in an illumination incubator at 25 DEG C after dormancy release and illuminated for 14 hours per day; the seeds are transferred to a shade place outside the room for continuous growth in June of the year; the medicago polymorpha blooms and bears pods successively in August and the mature seeds are harvested before October. The method for breeding and generation-adding of the medicago polymorpha, provided by the invention shortens a growth cycle of the medicago polymorpha, breaks dormancy of the medicago polymorpha seeds, and realizes two generations in one year for medicago polymorpha seed breeding.

The invention discloses a seedling combined planting method for bougainvillea speetabilis and evergreen leaf trees. The method comprises the following steps: planting a single bougainvillea speetabilis seedling and a single evergreen leaf tree seedling in a same potting bag, culturing at temperature of 20-25 DEG C; in a culture process, uniformly winding and fixing bougainvillea speetabilis branches on leaves of an evergreen leaf tree, when a plant grows to 0.5 m, spraying auxin once a week, when the plant grows to 1.2 m, stopping to use the auxin, illuminating the plant by ultraviolet for 5-8 hours every day, until the evergreen leaf tree seedling grows to 1.5 m, transplanting the seedling. Culture mediums in two different formulas are used in a soil matrix, being beneficial for rooting and growing of the seedling. In the method, the auxin is sprayed in the earlier stage, branches and stems grow rapidly, branches and stems are long and are easy to bind and fix. In a later stage, ultraviolet is used to irradiate the bougainvillea speetabilis and the evergreen leaf tree, growth of the bougainvillea speetabilis and evergreen leaf tree are restrained, so branches and stems age and tenacity is high, so the bougainvillea speetabilis and the evergreen leaf tree are firmly fixed, seedlings do not easily slump, and the method is beneficial for transplanting of seedlings.

The invention provides a method for artificially raising chrysanthemum chrysanthemums, comprising: Step S1: cultivating potted Dutch chrysanthemums and placing them indoors; Female adults of stinkbugs; step S3: using the potted Dutch chrysanthemum to raise chrysanthemum chrysanthemums. The present invention selects holland chrysanthemum to replace chrysanthemum chrysanthemum as a breeding plant for chrysanthemum chrysanthemum chrysanthemum. Replacement to minimize labor; in addition, Dutch chrysanthemum has a strong tillering ability, and it is mainly propagated by division. Therefore, the Dutch chrysanthemum purchased at one time can obtain new plants through asexual reproduction, and then continuously obtain breeding plants, reducing feeding costs .
