Effective use of land resources, especially desert sands and sandy soils, is becoming an increasingly important and urgent challenge in the consistent solution of the world's population's food supply crisis, which is becoming increasingly globalised due to its high growth rate (up to 11 billion by the end of the century).
After all, developing water-saving agricultural technologies for determining
and caring for low-water, fertile, and core crops that are ideal for these soil
and climatic conditions is of critical scientific and practical importance.
With the aid of field and
laboratory tests, we researched the technologies of sowing, fertilising, and
irrigating cotton, sunflower, soybean, peanuts, beans, potatoes, and carrots in
order to solve this urgent issue.
Results:
Sunflower cultivation in desert sandy soils used 4,362 m3/ha (1,144 m3/ha) less
water than typical crops (26.2 percent ).
Specifically,
during the period before sunflower harvesting, with intensive soy sunflower
sowing and joint care for sunflower and grain lasting 2-3 days, the total
amount of irrigating decreased by one time, and water savings of an average of
730 m3/s hectares were achieved.
At the same time, a total of 4395 m3 / ha of water was used for the two crops,
and by using ditch water in a 1:1 ratio, 2177 m3 / ha (roughly 50%) of river
water could be saved without causing soil and crop harm.
In terms of
the length of the growth period of soybean sowing, when sown in pure form, a
total of 6 times irrigating is permitted, resulting in 4332 m3/ha of water
being expended, while 2577 m3/ha of river water was saved in the ratio of 1:1
without harmful consequences.
Soybean growers
were able to plant carrots and grow two crops, using an additional 731 m3/ha of
water to do so.
Although caring for legumes up to 11 times, subject to permissible irrigation -
up to 8145 m3/ha and water consumption - up to 1606 m3/ha, the overall amount
of irrigations decreased by half, seasonal water consumption - up to 1606
m3/ha, or 19.7%, while caring for peanuts up to 11 times, subject to
permissible irrigation - up to 8145 m3/ha and water consumption - up to 1606
m3/ha.
In addition,
due to the efficient use of water, the drainage ditch was able to conserve 3256
m3/ha of river water in a 1:1 ratio.
Conclusion: The study found that yields are very poor, extremely unsuitable for agriculture, decreasing mineralization in desert sandy soils, leading to high water-resource-saving and economic productivity by jointly caring for sunflower and soybean crops, as well as eliminating water shortages.
