7 results about "Annual plant" patented technology

Methods for decreasing flowering time and accelerating crop cycle in plants and increasing the number of breeding cycles per year in such plants are provided. The methods comprise using far-red light alone or in combination with additional external signals such as photoperiod in order to decrease flowering time and accelerate seed to seed crop cycle. Also provided are methods for bypassing vernalization requirements in winter annuals.

The invention provides a method for constructing a perennial plant and application of the perennial plant. The invention discloses a new function of a gene, the gene is an FLC-like MADS-box gene and participates in regulation and control of perennial development of plants, and an annual plant is changed into a perennial plant. According to the method, the perennial plants can be obtained within a short time, and compared with a traditional mutagenesis method, the workload is small, the operability is good, and the method can be directionally completed through a single gene or multiple genes. Compared with a hybridization method, the method disclosed by the invention is small in workload and is not influenced by hybridization incompatibility among species. And perennial plants can be obtained in a short time.

The application discloses a kind of community structure water source driving cause-effect relationship analytical method, device, equipment and medium.It includes: obtaining soil water sample, plant water sample, precipitation water sample and groundwater water sample in target sample plot;The layered treatment of soil water sample obtains multilayer soil water sample and soil moisture content;The target sample plot is divided to obtain groundwater depth zoning data;The species number, species proportion and simpson diversity of annual plant and perennial plant are calculated as community structure characterization index;Test to obtain the isotopic characteristic data of each water sample, and input bayesian mixture model to calculate utilization ratio;Key water source factor is identified by redundancy analysis;The cause-effect relationship influence path is analyzed using partial least squares path model, and the complete cause-effect chain of community structure variation and ecological risk early warning basis are output.The present application realizes shallow groundwater grassland plant water source utilization quantification and water source driving cause-effect relationship analysis, and provides technical support for ecological early warning and water resources development.

The invention relates to a material board (1) which comprises a core (2) and a first cover layer (3) and a second cover layer (4), each of which is formed by a mixture (7, 8) formed by lignin-containing particles (5, 6) and binder, which mixture is designed to form a solid body structure in a chemical binding process. The aim is to provide a material panel, which, for ecological and economical reasons, comprises a high proportion of particles based on annual plants and still exhibits good mechanical properties. Another object of the invention can be considered that of ensuring that the system load is kept relatively low during the production process. Another object can be considered that of keeping the proportion of stock removal low. According to the invention, at least 70%, preferably at least 80%, most preferably at least 90% of the particles (5) associated with the mixture (7) of the core (2) are obtained from annual plants, and at least 70%, preferably at least 80%, most preferably at least 90% of the particles (6) associated with the mixtures (8) of the two cover layers (3, 4) are obtained from perennial plants. The invention further relates to the use of a material board and to a method for producing a material board. Finally, the invention relates to a system for producing a material board.

Provided in the present invention is a method for providing shelter from the wind and for fixing sand in a sandified grassland of Horqin, which method involves: S1, using an automatic sand barrier laying device to lay a mechanical sand barrier in the sandified grassland of Horqin, wherein a material for the mechanical sand barrier is one of or any combination of reed segments, straw mats, rice straw, Salix gordejevii, and Salix psammophila branches; S2, planting biological sand barriers inside the mechanical sand barrier to form a composite sand barrier, wherein the biological sand barriers are shrubs, and the shrubs are a combination of Salix gordejevii, Hippophae rhamnoides, Caragana microphylla, Caragana korshinskii, Corethrodendron fruticosum, Lespedeza davurica, and Artemisia halodendron; and S3, spreading seeds of herbaceous plants between the biological sand barriers, wherein the herbaceous plants comprise leguminous plants, gramineous plants and annual plants, and the ratio, by plant number, of leguminous plants : gramineous plants : annual plants is 3 : 5 : 1. By means of the technical solution of the present invention, the plant survival rate can reach up to 81.5%, and the coverage can reach up to 62.1%.

Process and installation for preparing a fibrous pulp from annual plant stems, and use of such a fibrous pulp. This process includes a grinding step in which whole annual plant stems (3) are ground to obtain a powder (4) containing mainly unfibrated stem fragments with a maximum dimension of less than 80 mm. The process also includes a sorting step in which the powder is separated into two fractions: fibrous elements that are intertwined to form a homogeneous fibrous mass (5), and particulate residues (6) that are free from the homogeneous fibrous mass, the particulate residues being removed.The process also includes a thermomechanical treatment step in which the homogeneous fibrous mass is introduced and continuously processed in an extruder (40), at the outlet of which an extrudate forming the fibrous paste is recovered.
