Liu Shiping's team at Yangzhou University created rice varieties that can be grown in salt water, and achieve yields of 6.5 to 9.3 tons per hectare. [ 12 ] [ 13 ] As of 2021, seawater rice had been planted on 400,000 ha (990,000 acres) in soils with up to 4 grams of salt per kilogram, with yields averaging 8.8 tons per hectare, according to ...
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'.
The plant's common name refers to its ability to tolerate salt water [21] by excreting salt into its leaves through specialized salt glands — thereby producing salt deposits which kill other species; [22] these salt deposits can also weaken interatomic binding in soil clays, leading to increased erosion. [21]
The latest hurdle comes from a slow-moving threat — a mass influx of salt water from the Gulf of Mexico that is creeping up the drought-stricken Mississippi River. ... but it can also kill ...
It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP). Glyphosate-based herbicides are used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops.
It is considered phytotoxic to all green plant parts. It can also kill through root absorption. Sodium chlorate may be used to control a variety of plants including morning glory, canada thistle, johnson grass, bamboo, ragwort, and St John's wort. The herbicide is mainly used on non-crop land for spot treatment and for total vegetation control ...
One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [59]
Remove the plant and its roots from the pot, carefully clean the roots and repot the plant. [6] Fertilizer can be reintroduced slowly to allow for slow, healthy recovery. Water the plant heavily to wash the accumulation of salt away. [11] If a plant is burnt due to drought-like circumstances, the soil may be dry, and the plant will appear wilted.
