The invention belongs to the technical field of desert ecological restoration, and discloses a hedge spiny seedling raising method and system for a field environment. The method comprises the following steps: collecting mature sedge seeds, treating for 3-5 minutes by using drum-type equipment at the rotating speed of 30-50 rpm, breaking the skin, and soaking the seeds in warm water at 38-42 DEG C for 10-12 hours; a modularized detachable seedling raising shed is adopted, movable non-woven fabric seedling raising bags filled with field soil, decomposed sheep manure (or biochar) and sand (the volume ratio is 5: 2: 1) are placed in the modularized detachable seedling raising shed, and an automatic drip irrigation system based on a soil humidity sensor is matched; and carrying out programmed seedling hardening 2-3 weeks before transplanting. According to the method, the embryo damage rate is controlled to be 1% or below, the seed germination rate is stabilized to be 90% or above, the transplanting survival rate reaches 90% or above, the water resource utilization efficiency is improved by 15-20%, operation is standardized, and the method is suitable for large-scale seedling raising in desert photovoltaic areas.

The invention discloses a method for preparing a natural essence base through synchronous co-extraction of ficus tikoua bur and aromatic plants, and belongs to the technical field of natural essence preparation. According to the invention, ficus tikoua bur is taken as a core raw material, synchronous co-extraction is carried out on the ficus tikoua bur and one or more aromatic plants without chemical conflicts, and single-stage distillation, single-stage extraction or single-stage adsorption is carried out in one step to prepare the composite natural essence base. According to the method, synergistic retention and overall flavor integration of various plant aroma components are achieved through synchronous co-extraction, the technological process is simple, the conditions are mild, and the flavor level and composite characteristics of the natural essence base are effectively improved. The obtained composite natural essence base has the characteristics of high natural identification degree, strong stability and incapability of being completely re-engraved through chemical essence, and can be widely applied to the development of food, cosmetics, wash care, aromatherapy and various aromatic products.

This invention provides a method for identifying and locating the maturity of okra flowers based on non-parallel-placed cameras, comprising the following steps: two non-parallel-placed cameras capture images of the plant from different directions; color blocks in both cameras that reach a set threshold are marked as flowers; each image marked as a flower is binarized and edge extracted; the variance of the distance from each pixel on the edge of the closed shape to its geometric center is calculated; the flower shape is determined based on the variance; and the location of mature flowers is determined. This invention also provides a device for detecting and locating the maturity of okra flowers based on non-parallel-placed cameras. The method and device of this invention utilize non-parallel-placed cameras to acquire images of the target crop, calculate its three-dimensional coordinates using the two-dimensional spatial coordinates of the flower obtained from each of the two cameras, and simultaneously use the flower's morphology and color information as a basis for determining whether further processing is required.

The present application relates to the technical field of invasion plant prevention and control, in particular to a method for controlling ipomoea nil by sequentially using beneficial epiphyte fungi and pathogenic bacteria, which comprises the following steps: S1, stimulating excessive immunity, spraying G.fujikuroi spore suspension with a concentration of 3×10 7 Individual leaf spraying amount is 2.5 ml, and the ipomoea nil plants are placed in an environment with a temperature of 25±5 DEG C and a relative humidity of 85±5% for 2 days; S2, immunity decline, waiting for 3 days; S3, applying pathogenic bacteria, spraying Colletotrichum gloeosporioides spore suspension with a concentration of 2×10 6 Individual leaf spraying amount is 2.5 ml, and waiting for 2 days. A new technology of using low pathogenic Colletotrichum gloeosporioides as a biological control agent for ipomoea nil is created, and a green new way of weakening the immunity of the plant without using chemical fungicides is provided. The disease resistance of the plant is weakened, and then the ipomoea nil plants with weakened immunity are infected by Colletotrichum gloeosporioides.
