What are the advantages of corn no-tillage sowing, and can it really improve the ability of water storage and moisture conservation?

No-tillage corn usually refers to summer corn, that is, corn sown after harvesting wheat. For example, in Guangdong, almost all summer corn is planted without tillage. Because the economic benefit of corn itself is very low, if wheat is harvested to cultivate land, the cost will increase immediately. At present, straw is not allowed after wheat harvest, which is not conducive to farmers' farmland, and it is more difficult to sow after farmland, so no-tillage is certain. So how can we reduce the soil hardening problem of no-tillage corn? Nature is deep broadcast.

At present, most corn seeders are actually operated by corn seeders installed behind small tractors. You can sow two or three rows at a time, so that the hook of the seeder can be adjusted deeper and soil hardening can be greatly reduced. Another situation is that if the environmental humidity in the wheat field is high, the rice harvester will crush the soil after harvesting the wheat, so when sowing corn, try to avoid the crushed part so that the corn seeds will not be exposed on the ground. If there is drought in the soil layer, water injection must be carried out after sowing, so that corn can grow fully.

Compared with the traditional operation mode, no-tillage sowing does not need immediate farmland operation, which ensures excellent operation quality, improves operation efficiency and reduces operation cost. In addition, when sowing in the field with no-tillage seeder, it is not necessary to remove the straw and its surface stubble in advance, and it is not necessary to carry out cooperative tillage with stubble removal, so a variety of technological processes can be completed together, such as furrow application of organic fertilizer, precision sowing, and suppression before filling. In addition, there is no need for stubble cleaning and ridging, which can also significantly reduce the construction time, save the operation cost, and help farmers master the soil moisture and sow moderately.

Improve the ability of water storage and soil consolidation, and reasonably prevent soil hardening. After the operation of no-tillage seeder, the water storage capacity can be improved, which is conducive to maintaining the stability of seedlings and soil consolidation, and it is not easy to cause fertilizer outflow, thus ensuring more development and utilization of fertilizer efficiency, improving work efficiency and further increasing corn yield. In addition, no-tillage seeder can significantly reduce the frequency of agricultural machinery used in the field, and then reduce the degree of inhibition on soil environment. In addition, the adhesion between soil layers can be reduced and soil hardening can be effectively prevented without plowing and raking.
