Saline-alkali soil improver helps increase cotton production in Xinjiang

It has both salt-alkali tolerance and water-retaining and controlled-release fertilizer effects

It has both salt-alkali tolerance and water-retaining and controlled-release fertilizer effects

"This year, we have independently developed a saline-alkali soil improver in Korla, Xinjiang.
The phenotypic traits of cotton growth have been significantly improved.
The yield of Yumian 54 increased by 15.
96%, and the yield of Yinshan 20 increased by 13.
47%
.

"On November 2, Yu Xuejun, director of the High-tech Research Center of the Henan Academy of Sciences, said

This salt-alkali soil improver is independently developed by the green chemical research team of the High-tech Research Center of Henan Academy of Sciences
.

The project leader Dr.

According to Yu Xuejun, this research started 15 years ago
.

At that time, in order to control the saline-alkali soils in Henan Lankao, Puyang and other places, the Henan Academy of Sciences organized scientific research team members to consult literature, survey sampling, laboratory synthesis, and pot experiments.

"Xinjiang is the country’s largest cotton producing area.
The cotton planting area accounts for about 3/4 of the country’s total output, accounting for more than 85% of the country’s total output.
Xinjiang is also one of the provinces with the largest area of ​​saline-alkali land in China, with an area of ​​110,000 square kilometers of saline-alkali land.
Rice, which accounts for about 1/3 of the country’s saline-alkali land area, is short of water resources.
It is urgent to develop water-saving saline-alkali land improvement technology to further improve the efficiency of cotton planting
.

After many inspections, we decided to conduct planting experiments in Xinjiang

　　"Saline-alkali drought has become a major problem affecting the sustainable development of cotton production in Xinjiang
.

" Tang Zhongjie, deputy director of the Cotton Research Office of the Institute of Economic Crops, Henan Academy of Agricultural Sciences, said, Henan Academy of Agricultural Sciences and Henan Academy of Sciences High-tech Research The center cooperated to carry out soil salt-alkali improvement research at the Nanjiang Cotton Experimental Station of the Henan Academy of Agricultural Sciences in Korla, using a multi-variety, multi-gradient, and multi-repetition test program, and drip irrigation of saline-alkali soil improver in the whole growth period of cotton 8 times

　　"This modifier has a good test effect on Xinjiang's saline-alkali soil, and has a good use value for increasing cotton production in Xinjiang
.

With further tests and demonstrations in the future, the saline-alkali soil modifier will support Xinjiang cotton and scientific and technological assistance.

　　"Improving saline-alkali land is a major measure to alleviate human-land conflicts and ensure national food security.
It is also an urgent need to improve the regional ecological environment and promote high-quality economic and social development
.

Next year, we are going to continue to expand and optimize experiments in Xinjiang to investigate different cotton The role of varieties, saline soil, water saving, etc.
