Whether excessive soil moisture is conducive to plant rooting

Proper soil moisture is good for plants to take root, while too high humidity is easy to breed bacteria and cause plants to rot roots.

Making the soil at the roots of the plant softer and the right humidity is the way to make it easier for the roots of the plant to take root. If you want to take cuttings, it is best to use vitamin B12

Soak the underside of the cuttings.

After drying, the cuttings will be better. After cuttings, do not expose the cuttings directly to the sun, but put them in a cool and ventilated place, so that the cuttings will not die due to excessive water loss. However, if you lose too much water, you can make the nutrients in the stem of the cuttings fully play a role and grow roots.

The effects of soil moisture discomfort on wheat populations were manifested in the decrease of dry weight and leaf area index (LAI) per unit area. Path analysis was used to measure the effects of seedling emergence rate and seedling growth per plant on the population. The results show that:

The decrease in dry weight per unit area was mainly due to the decrease in dry weight per plant, and the decrease in leaf area index was mainly due to the decrease in seedling emergence rate. When soil moisture is greater than 17 and less than 44, the influence range on wheat seedling emergence and seedling growth is generally within 20, while the influence range of soil moisture lower than 17 or higher than 44 on wheat increases sharply. Wheat has a certain adaptive response to soil moisture discomfort.

1.Soil moisture greater than 17 percent and less than 44 percent is the most suitable for plant growth.

Humidity is the moisture content of the soil, in the field profile observation, distinguish the degree of soil wetness, generally measured by dry, slightly moist, moist, damp, wet, to hand test, there is a significant cooling feeling for dry. Slightly cool and not feeling moist is slightly moist. Obviously moist, can be pressed into various shapes without wet marks for moisture.

When squeezed by hand, no water leachs out, and there are wet marks for moisture. Squeeze it by hand, and the water will appear wet.

3.Soil moisture is too high, deteriorates soil aeration, affects the activities of soil microorganisms, and hinders the respiration and growth of the roots of the destroyed crops, thereby affecting the normal growth of the aboveground parts of crops, resulting in overgrowth, lodging and disease breeding. The amount of soil moisture also affects field tillage practices and sowing quality, as well as the level of soil temperature.

Low soil temperature can affect the ability of plant roots to absorb water for two main reasons:

1.Affect root metabolism and activity: If the soil temperature is too low, it will affect the metabolism and activity of plant roots, resulting in a decrease in the water absorption capacity of the roots.

At low temperatures, the metabolic rate and enzyme activity of plants will decrease, and the metabolism of root cells will be slow, and they cannot effectively produce ATP and other cellular energy substances, which affects the absorption and transportation of water cavity sources by roots.

2.Affect the state of water in the soil: At low temperature, the water in the soil condenses to form ice crystals, which reduces the porosity of the soil and reduces the permeability and fluidity of the water, thus affecting the water absorption and transport of the root system.

In addition, low temperatures can also reduce the number and activity of microorganisms in the soil, reducing the decomposition of organic matter and the release of nutrients in the soil, thus affecting the growth and development of plants.

Therefore, when the soil temperature is too low, some measures should be taken to increase the soil temperature, such as covering insulation materials, increasing organic fertilizers, improving soil structure, etc., to promote the water absorption capacity and growth and development of plant roots.
