The present invention provides a plant salt-resisting agent, its preparation method and application method. The plant salt-resisting agent is made up by using manganese sulfate, sodium nitriphenolate, alpha-naphthylacetic acid, gibberellic acid, urea, humic acid and clean water through a certain preparation process. Said invention also provides the concrete steps of its preparation process. Said plant salt-resisting agent can be used for soaking seeds, and can raise yield of crops planted in the saline-alkaline land.

The invention discloses a wind prevention and sand fixation greening planting technology with good sand control effect. The wind prevention and sand fixation greening planting technology mainly comprises the following steps of: firstly arranging a plurality of strip sand-protecting barriers in a traveling dune zone; then mix-seeding herbaceous plant seeds in open grounds among the strip sand-protecting barriers, and planting shrub seedlings at the positions where the strip sand-protecting barriers are located; and finally fertilizing among the strip sand-protecting barriers and inside the strip sand-protecting barriers. According to the wind prevention and sand fixation greening planting technology, normal germination growth of most herbaceous plant seeds and shrub seedlings can be ensured without planting by multiple times; moreover, the growth period of herbaceous plants is relatively short, so that grass capable of sand fixation can be formed in a short time to further ensure normal growth of shrub seedlings; a grass and shrub forest can be formed in a relatively short time, two to three years in general, through the combination of the sand fixation of sand-protecting barriers with grass and shrub plants so as to achieve the effects of wind prevention and sand fixation; and the desertification of land can be effectively prevented. The technology is suitable for popularization and application in the technical field of sand control.

The invention discloses application of ABI5 protein and its coding gene in regulating oxidative stress resistance of plant seeds. The application of the invention is any one of the following applications (a1)-(a6) of protein composed of amino acid sequences as shown in Sequence 3 in the sequence table: (a1) regulating oxidative stress resistance of plants; (a2) raising oxidative stress resistanceof plants; (a3) breeding plant varieties with enhanced oxidative stress resistance; (a4) regulating resistance of plants to herbicides; (a5) raising resistance of plants to herbicides; and (a6) breeding plant varieties with enhanced resistance to herbicides. The application of the invention is helpful for the research on molecular mechanism of oxidative stress resistance in the plant seed germination process, improvement of seed quality and stress-resistance traits and breeding of plants with oxidative stress resistance, meets requirements of agricultural production, brings greater economic benefits to crop production, and has important practical value and market prospect.

The invention provides a method for raising coral tree seedlings, which belongs to the technical field of coral tree planting, comprising: 1) pretreatment: taking coral tree seeds and disinfecting them in potassium permanganate solution at 36-38°C; The pretreated coral tree seeds are acid-etched with a mixed concentrated sulfuric acid solution containing ether; 3) Hormone treatment: the acid-etched coral tree seeds are soaked in an ethanol solution containing indole acetic acid and fluorenemethanol; 4) germination by low-temperature stratification : Carry out wet and cold stratification germination to coral tree seeds with 3-5 year old pine sawdust; 5) Sowing: Seedlings are sown after being disinfected and disinfested, and germinate and grow into seedlings. The beneficial effects are: the method is easy to implement, can effectively awaken coral tree seeds in a dormant state, helps to stimulate the growth and development of radicles, accelerates the germination of radicles, improves the germination rate of seeds, accelerates germination, and the germinated seedlings are strong and transplanted. Planted high survival rate.

The invention belongs to the technical field of agricultural microbiology, and specifically discloses a strain of Bacillus velesii and its application in biocontrol. Veles bacillus of the present invention is Veles bacillus ( Bacillus velezensis ) Bv‑6, the deposit number is: CCTCC NO: M20191106. Bacillus Veles fermentation broth or its powder can effectively inhibit the mycelium growth of important pathogenic bacteria (Sclerotinia sclerotiorum, Botrytis cinerea, black shank of rapeseed) on rapeseed, and the germination of conidia and ascospores; the soaking treatment of rapeseed seeds in fermentation broth can Normal germination and growth can improve the disease resistance of plants. In addition, Bacillus Velez has the characteristics of fast propagation speed, high stability, high temperature resistance and non-toxicity. Therefore, Bacillus veleisi strain Bv‑6 has the potential of biocontrol function development and utilization.

The object of the present invention is to provide a method for cultivating rice seeds regenerated from old age. In the breeding method, the wild rice containing genes for cold resistance and developed root system is used as the male parent, and the DS89-1 glutinous rice is used as the female parent, and repeated crosses are carried out for 3 to 5 times to obtain the regenerated rice seeds. The invention also provides a method for growing seedlings of the regenerated rice seeds. The older regenerated rice seeds obtained by the cultivation method of the present invention, the rice planted according to the seedling raising and planting method, have high yield and rice yield, good rice quality, can be regenerated over the years, and are resistant to cold, drought, lodging, and The advantages of strong rice blast ability.
