The United StatesA orchard in Davis California looks like the "hell" of plants.A row of apricot trees grows here, but the living environment is very bad. They are facing drought and exposure, and the almond training division Tom Gradziel does not intend to water these trees He just walked in the orchard, and occasionally tasted the fruit of the apricot tree.
The living conditions of the apricot tree here are not good.｜ CAES.UCDAVIS.edu
Other plants are also tortured.For example, some people specifically specifically on high -salinous soil .
If the soil contains too much salt, the plant will not survive normally.This is because the salt content is too high, the water in the plant root will flow back to the soil, causing the plant to dehydrate and even kill the plants; at the same time, the high sodium content will destroy the original structure of the original Plains in the soil , and the soil will be .It affects the pores, breathability and water conduction of soil.According to research, high -salinity soil reduces the output of crops by 20%to 50%.
The consequences of the torture of salt are that the fruits that are happy with the fruit are very small and can hardly eat, but the tree is still alive.The walnut tree almost died.People also try to torture pomegranate trees and other nut trees with high salt, extreme drought.
The leaves of a happy fruit tree growing on high salt soil are also weird.｜ Pat J. Brown
In short, in this orchard, there are basically no plants that can grow normally and normal.In fact, this orchard was designed by Botanists at the University of California, Davis, called "torture farm" .
It seems to be an artificial "torture", which is actually the future that humans are about to face .Under the situation of climate change today, the condition of drought will become more frequent and more serious.In addition, agricultural water should account for 70%of the total water consumption. In the case of drought and water resources, farms around the world are actually facing major challenges.
In the future, crops will face an increasingly serious survival crisis.｜ CAES.UCDAVIS.edu
At the same time, due to extreme weather, water shortage, pollution, and use of chemical fertilizers, the degree of saline is also intensified.According to the information, 14 square kilometers of fertile land disappears due to soil saline.
Therefore, the University of California, Davis, designed such a orchard that these crops will suffer the "torture" that may come to the earth in the future and monitorThe survival of these plants, see how drought tolerant they are, and trying to introduce more resistant varieties.
Botanologists have found that in this harsh orchard, although the crops such as apricot trees are not good, no tree dies.Decades ago, apricot trees entered California, and the reason why it dominated is the drought resistance.However, in recent years, even the local apricot trees have not been able to withstand the more and more drought.
Since 2004, the torture orchard has begun "survival of the fittest". Planting is more likely to die and save more water, such as apricot trees introduced from the Middle East, from TurkmenistanThe pomegranate trees and so on.Botanist hopes that These plants can not only be more robust, but also crops that can be "left to future descendants".
People may need to find some more resistant crops for future food supply.｜ Pat J. Brown
In addition, the innovation of irrigation technology is also one of the answers that researchers want to find.For example, meteorological stations and soil detectors will accurately calculate how much water needs to be calculated, such as gravity micro irrigation, underground irrigation systems, etc. These experiments not only allow us to know more about plants, but also "investment in the future".
Little readers of the "Everything" magazine, in fact, often share with us "plant experiments" in their lives!For example, in the ending of the "Scientific Experimental Battle", we saw many children who began to plant various plants at home, and carefully analyzed the growth of these plants.
In the "Everything" magazine in August 2024, we published an innovative design of a little reader: this 11 -year -old reader uses the family to use the familySweet potato fish tank !Not only the plants thrive, but the ecological environment underwater is richer.
Another child shared that it is not easy to plant a pot of sunflowers.If you water too much or fertilize too much, you will let the sunflower be collapsed ...
In addition to the scientific experiments that enable the editors to open their horizons, there are more wonderful compilation readingExchange activities, encourage you to discover the science around you!For example, in the November issue, little readers shared the science in their hometown scenery.
Some readers shared Sanhao Bridge in Shenyang . This worlds first steel arch tower cable -keeping bridge has better stability, and construction is more convenient ...There are also readers who share Geanghua, Yingxian Mu Tower, Shanghai Central Building in Hometown ...
Believe in your hometown,There are also such attractions that allow people to learn many scientific knowledge.Welcome to share with us the scientific discovery in your life!
Dont forget to pay more attention to the reader activities of the "Everything" magazine service number ~ Actively participate, you will have the opportunity to get mysterious gifts!
"Everything" magazine also has more exciting content waiting for you to discover!
