The application belongs to the technical field of plant stress resistance regulation, and particularly relates to application of kynurenic acid in improving salt stress adaptability of cynodon dactylon. The application finds that, before and / or during salt stress, exogenous application of kynurenic acid to cynodon dactylon can significantly reduce the degree of oxidative stress (H2O2), the level of membrane lipid peroxidation (MDA) and the content of osmotic regulator substance proline, effectively relieve salt damage reaction and improve the adaptability of cynodon dactylon in a high-salt environment. The method is simple in operation, suitable for plant remediation and environmental protection planting in saline soil, and has a good application prospect.

The invention discloses a method for selectively extracting plant xylem embolism conduit juice, and belongs to the technical field of plant physiology research. In order to solve the problem that pure embolism catheter juice cannot be distinguished and obtained in the prior art, a plant stem section in a specific water stress state is obtained, the morphological lower end of the plant stem section is connected with a hydrophobic extracting solution, the upper end of the plant stem section is connected with a collecting system applying 0.01-0.1 MPa negative pressure, the extracting solution is driven by the negative pressure to selectively enter and flow through an embolism catheter, and the juice in the embolism catheter can be obtained. Meanwhile, due to the fact that the applied pressure is far smaller than the pinhole membrane fixing force borne by a water column in the functional catheter, the juice in the functional catheter can be reserved. Specific extraction of embolism catheter juice is realized for the first time, and a reliable method is provided for directly analyzing physicochemical properties of the juice and researching an osmotic regulation mechanism of xylem embolism repair.

The invention provides a novel anti-cracking regulation and control method for stone fruits of prune plums, and relates to the technical field of fruit tree cultivation and pest control. According to the method, the osmotic pressure and the growth rhythm of fruits are regulated and controlled by adopting a composite reagent of cytokinin, gibberellin, diethyl aminoethyl hexanoate and an osmotic regulation substance at two key nodes of 10-15 days after flower abortion, the end of a hard core period and the start of a second expansion period, and four physical measures of organic fertilizer application, orchard grass growing, ridging and drainage and post-raining water removal are combined. The growth speed of peel is slightly higher than that of pulp, and tree moisture supply and demand are stable. The core innovation lies in osmotic pressure saturation regulation technology, peel and pulp growth rhythm matching regulation and physical and chemical synergistic anti-cracking. Practice verifies that the fruit cracking rate of prunes and plums is reduced to be within 5% from 80%-90%, the commodity rate of fruits is larger than or equal to 95%, a rainproof shed does not need to be built, the cost is reduced by 60% or above, operation is easy and convenient, popularization is easy, and the method is suitable for cultivation of prunes and plums in different regions such as Xinjiang and Yunnan.

The application discloses a seawater desalination equipment with adjusting control function, and relates to the technical field of seawater desalination equipment. The intake mechanism is responsible for efficiently and stably extracting seawater to be treated from a marine environment and performing primary filtration on the seawater, effectively blocking large-particle impurities and algae and avoiding the impurities and algae from entering subsequent processes. The seawater after the primary filtration is delivered to a pretreatment mechanism through a pipeline, the pretreatment mechanism further filters the seawater, and the operation efficiency of a subsequent reverse osmosis process and the service life of a membrane assembly are improved. The reverse osmosis adjusting mechanism controls the permeation flow, the membrane surface pressure and the running state of the wound membrane assembly accurately, significantly improves the permeation performance of the membrane surface, and the membrane surface cleaning mechanism periodically effectively cleans the reverse osmosis membrane surface, removes the impurities and deposits attached to the membrane surface and avoids the occurrence of the membrane surface blockage phenomenon, thereby long-term maintaining the efficient permeation performance of the membrane.
