What is the purpose of the farmer s uncle to loosen the soil after watering?

Loosening the soil after watering is first of all because capillary phenomenon is easy to occur when the soil is dry and becomes a whole block.

The very thin capillary in the stem of the plant will absorb the water in the soil, and the soil will not be able to retain water and lose water. In addition, it is not easy to cultivate and loosen the soil when the soil is dry, because the soil is formed into plates, so watering the soil will make the soil soft and moist, so it will be easy to carry out farming, save time and effort, improve the labor efficiency of farmers, and can also reduce high-intensity farming, so that farming activities are faster. <>

If you want to get better nutrition for plants, you need to remove some of the old roots on the surface of the soil by loosening the soil, so that you can touch new life, the crops absorb better nutrients, and then the root system is also developed and strong, which can improve the aeration and permeability of the soil, and the plants get better water。The growth of plants needs oxygen, if the soil is loosened, it can increase the void between the soils, which can also increase the oxygen content between the soils, which is conducive to the circulation of air and promote the growth of plants.

There will be a lot of pests and diseases in the soil, some pests will affect the growth of crops very much, and the reproductive ability is particularly fast, not easy to eliminate, if the soil is loosened, you can directly kill some pests, and reduce the existence of some germs, curb the growth of germs. Effectively prevent the damage of pests and diseases to crops. In addition to pests and diseases, there are also many weeds in the soil, which grow and spread quickly, and can rob and affect the nutrients of the cropPhotosynthesis, causing the crop to grow slowly or not being able to absorb nutrients and water and stop growing.

Therefore, we should loosen the soil when watering the soil to maintain soil moisture, so as to better ensure the vitality of the soil and the acquisition of crop nutrients.

Reducing the growth of pests, diseases and weeds, preventing soil slabs and helping crops absorb nutrients and better replenish water are all done by loosening the soil, and the water storage capacity of the soil will directly affect the growth of crops.

The reason for the loosening of the soil after watering the soil by the farmer should be as follows: When the soil is loosened, the water will penetrate more deeply, and the roots will be able to absorb the water better. At the same time, when the soil is loosened, the carbon dioxide in it runs faster, and more oxygen goes in.

The main purpose of this is to allow the soil to breathe, so that the plants can have higher yields.

When the soil is loosened, the water will penetrate deeper and the roots will be able to absorb water better. At the same time, if the soil is loosened, the carbon dioxide in it will run faster.

a. The roots of the plant breathe the oxygen in the air Frequent loosening of the soil can loosen the soil, increase the air in the soil crevices, which is conducive to the respiration of the roots and promotes the growth of the roots, so loosen the soil for crops - it is conducive to the respiration of the roots, correct;

b. Sowing seeds in moist soil - seeds need water for germination, correct;

c. Carbon dioxide is the raw material for photosynthesis, so it is correct to supplement carbon dioxide for greenhouse crops during the day - to enhance photosynthesis;

d. Applying chemical fertilizer for greenhouses - providing inorganic salts for plant growth, the organic matter needed for plant growth is made by plants themselves through photosynthesis, which is incorrect

Therefore, d
