CCTV News: Liaoning Province, one of the main grain-producing areas in my country, recently officially issued the 2025 black soil protection tillage implementation plan. ພື້ນທີ່ຂອງວຽກງານການປ້ອງກັນຂອງແຂວງທີ່ຖືກປະຕິບັດໃນປີນີ້ຈະບັນລຸໄດ້ 13,7 ລ້ານ mu. ນີ້ກໍ່ແມ່ນປີທີ 5 ຕິດຕໍ່ກັນວ່າ Liaoning ໄດ້ສົ່ງເສີມການປ້ອງກັນການປົກປ້ອງດິນດໍາທີ່ແຂງແຮງ. ຕໍ່ໄປ, ໃຫ້ຕິດຕາມນັກຂ່າວຈາກສະຖານີສູນກາງເພື່ອເບິ່ງວ່າການປູກຝັງປ້ອງກັນແນວໃດໃນ Liaoning ກໍາລັງດໍາເນີນການ? ມີການປ່ຽນແປງຫຍັງແດ່ທີ່ເກີດຂື້ນກັບດິນດໍາ?
ເຂົ້າສາລີພືດໃນງານບຸນ qingming ແລະປູກທົ່ງນາຂະຫນາດໃຫຍ່ໃນຝົນຕົກ. ໃນສອງມື້ທີ່ຜ່ານມາ, ນັກຂ່າວໄດ້ມາເມືອງ Chenbei New Bund, ເມືອງ Shenyang, ຫນຶ່ງໃນເຂດພື້ນທີ່ຜະລິດສາລີຕົ້ນຕໍໃນແຂວງ Liaoning. It is less than a week before large-scale spring sowing of corn, and the straw left after harvest last fall is still retained in the large area of farmland in front of me. Agricultural machinery expert Li Xuemei and grain grower Yang Changchun were following behind a large agricultural machinery to carefully check the operation results.

Yang Changchun said that farmers have an account in their hearts. ຫຼັງຈາກການເກັບກ່ຽວສາລີໃນລະດູໃບໄມ້ປົ່ງທີ່ຜ່ານມາ, ເຟືອງແມ່ນຖືກເຜົາດ້ວຍຟືນຫຼືຂາຍເປັນມັດແລະໃຫ້ນົມ.
Starting from 2020, Liaoning will continue to promote the implementation of black soil protection farming, and the total task area this year will reach 13.7 million mu. At the same time, local governments are encouraged to increase the implementation area based on the planned task area, increase demonstration and promotion efforts, and continuously expand the radiation and driving area.
Why does the country have to spend so much effort to pay so much real money and silver subsidies, and find ways to let farmers ອອກຈາກເຟືອງໃນສະຫນາມ? ເຟືອງທີ່ມີບັນຫາແລະບໍ່ມີຄ່າແນວໃດໃນສາຍຕາຂອງຊາວກະສິກອນໃນອະດີດກາຍເປັນ "ຕໍາທອງ"?
Zhu Baoyu, director of the Agricultural Machinery Production Management Office of the Liaoning Provincial Department of Agriculture and Rural Affairs, said: "Protective tillage, straw covering is like covering a small quilt. In autumn and winter, including when the wind and sand are very strong and drought before sowing in spring, straw covering can achieve a very good effect of protecting arable land such as windproof, soil protection, and sand ການແກ້ໄຂ.

Yang Changchun, chairman of an agricultural machinery professional cooperative in Chenbei New District, Shenyang City, said: "In the past, when it was so windy, you might not be able to open your eyes when you went out. The soil was rolled away, and now the straw was covered on the soil, so this situation was very rare. (Reporter: What if it rains heavily?) It's okay to rain heavily. If it rains heavily, the straw will reduce water erosion. Otherwise, the water will flow wherever it is, and the ditch will rush out of the ditch here."
Liaoning: Straw returns to the field No tillage and less tillage, so that black soil can be used sustainable
Among the people of Northeast China, fellow villagers once used "one twelve soil and two twelve oil" to describe the fertility of black soil. However, long-term large-scale planting and continuous cropping and traditional farming methods that pursue high yields have put precious black soil in a dilemma of both soil quality and fertility, and large-scale fallow land will cause grain production to be reduced. ບັນຫາຂອງ "ຄົນຫນຶ່ງທີ່ແຂງກະດ້າງ" ເຖິງ "ສອງສົ້ນຂອງການອຸດຕັນ" ແມ່ນສໍາຫຼວດທາງອອກໃນການປະຕິບັດການປົກປ້ອງການກະສິກໍາຂອງ Liaoning.
In the farmlands of Fuxin Mongolian Autonomous County, Liaoning, the full amount of straw is being returned to the fields and raking mixed operations. Modern agricultural machinery rumbles and rolls up and down, breaks the straw through high-speed blades, mixes about 70% of the straw and soil to the tillage layer, and leaves about 30% of the straw on the surface to cover it, completing the entire process of rotary tillage, crushing, mixing and land preparation at one time.
Li Jianping, a technical instructor of an agricultural cooperative in Aiyouyingzi Village, Fuxin Mongolian Autonomous County, said: "Through machine land preparation, organic matter (straw) is integrated into the soil, the content of organic matter is maintained, the soil fertility is increased, and the soil has a certain effect on the soil moisture conservation and softening. Through this one-time land preparation, the land is reduced."
The above-ground straw cover reduces wind and rain erosion of the land, and a large amount of straw is returned to the field under the ດ້ານ. ຫຼັງຈາກຖືກຕີແລະປະສົມກັບດິນ, ມັນຈະເຮັດໃຫ້ສິ່ງເສດເຫຼືອ, ເພີ່ມຂື້ນສົມບັດ, ເພີ່ມຄວາມສາມາດໃນພື້ນທີ່ຂອງດິນກະສິກໍາ.
The black soil in Northeast China is one of the major black soil belts in the world and is the largest commercial grain base in my country. The reason why black soil is "black" is because it is covered with a layer of black or dark black humus, which is loose and rich in organic matter, and is suitable for farming. ເຖິງຢ່າງໃດກໍ່ຕາມ, ພາຍໃຕ້ການຜະລິດແລະການຜະລິດໃນໄລຍະຍາວ, ຊັ້ນຂອງດິນດໍາແມ່ນບໍລິໂພກຢູ່ສະເຫມີ. In order to maintain soil fertility and high grain yields, the excessive use of a large amount of fertilizers was once a helpless move for farmers. Nowadays, modern farming technology with straw covering returning to the field as the main content has given new answers to black soil protection.
