The present application relates to the field of agricultural technology, and discloses a kind of plug seedling substrate and its preparation method and application.The plug seedling substrate includes the following components: tea dregs, coconut bran, inorganic porous material and functional liquid;Wherein, the functional liquid includes the following components: ikdoine, natamycin and polyglutamic acid.The plug seedling substrate provided by the present application provides air permeability with tea dregs, provides water retention with coconut bran, and uses inorganic porous material as the substrate framework, meeting the requirements of seedlings for substrate water retention, air permeability and root growth space, by adding functional liquid containing active ingredients ikdoine, natamycin and polyglutamic acid, while solving the three major problems of water management, disease control and root development.Plug seedling.The tea dregs after extracting tea polyphenols and coconut bran replace non-renewable peat, realizing high-value utilization of agricultural waste, and compared with non-renewable peat, the raw material cost is low and more environmentally friendly.

The invention provides Pseudomonas kirscheri WF3, a microbial fertilizer for saline-alkali soil and a preparation method and application of the microbial fertilizer, and belongs to the technical field of biological composting. The invention provides a preparation method of a microbial fertilizer for saline-alkali soil. The preparation method comprises the following steps: (1) preparing a fertilizer carrier comprising a decomposed organic fertilizer, humic acid, attapulgite powder and polyglutamic acid; and (2) inoculating pseudomonas kirschner WF3 into the fertilizer carrier, and carrying out sealed fermentation to obtain the microbial fertilizer for saline-alkali soil. Pseudomonas kirschner WF3 which has exopolysaccharide and organic acid production capacity and can survive in a strong saline-alkaline environment is adopted for fermentation of a fertilizer carrier, the prepared microbial organic fertilizer can effectively improve the content of organic carbon, total nitrogen and water-stable large aggregates (larger than 2.5 mm) in soil, increase the yield of corn, reduce the pH and total salt content of the soil, and improve the yield of corn. The improvement effect on the saline-alkali soil is obvious.

The application of ferulic acid in promoting the growth of rice seedlings and increasing the yield of rice in saline-alkali land, the application of ferulic acid in rice is disclosed.The application provides a new application method of ferulic acid, i.e.the application of 5-20 micromole / L ferulic acid in promoting the growth of rice seedlings and increasing the yield of rice in saline-alkali land.The application of ferulic acid in promoting the growth of rice roots, the development of rice seedlings and increasing the salt tolerance of rice in fields, and the positive effect of ferulic acid on the growth and development of rice through the application of low-concentration ferulic acid are illustrated, which breaks the cognition of most people that ferulic acid inhibits the growth and development of plants to a certain extent.Especially, the application of ferulic acid in increasing the alkali tolerance of rice, and the application of low-concentration (5-20 micromole / L) ferulic acid enhances the alkali tolerance of rice and increases the yield of rice.

The application belongs to the field of agricultural biotechnology, and more particularly relates to application of a TasA protein in improving stress resistance of rice. The amino acid sequence of the TasA protein is shown as SEQ ID NO. 1, and the rice tolerance to high temperature and drought stress can be significantly improved. Experiments show that the use of a rice stress resistance regulator containing the TasA protein can effectively alleviate the inhibition of stress on plant growth. Compared with the untreated group, the rice seedlings to which the rice stress resistance regulator containing the TasA protein is applied have a significantly increased plant height, fresh weight and dry weight under high temperature stress, and also show a better growth state under drought stress. The rice stress resistance regulator provided by the application has a simple use method and low cost. The application provides a new technical path for improving crop stress resistance by using an exogenous TasA protein, and is suitable for stress resistance improvement of rice and other crops.

This invention provides a soil conditioner, its preparation method, and its application, belonging to the field of soil remediation technology. The soil conditioner, by mass percentage, comprises the following components: 95%–97% tobacco straw, 0.5%–2% *Ulva prolifera* polysaccharide, 0.1%–0.5% fucoidan oligosaccharide, and 1%–2.5% *Bacillus* powder. Through the synergistic effect of its components, the soil conditioner provided by this invention can effectively improve soil compaction in coastal saline soils, enrich soil microbial biodiversity, and simultaneously enhance the salt and drought resistance of plants growing in coastal saline soils, thereby promoting plant growth and development.
