Soil quality is mainly divided into sand, clay and loam. Each of the three soils has its own characteristics, the most obvious difference being the ability to retain water. So if you are using the same kind of watering for all three soils, do you think it is appropriate? That will definitely not work.
1 Sand: Sand should be poured in large water. The biggest feature of sand is that the soil gap is large, and the water is easy to infiltrate and lose. This kind of soil, its own water retention and fertilizer capacity is weak, so it is easy to cause crops lack of water and fertilizer. However, the advantage of sand is that it has good gas permeability and is active in aerobic microorganisms. However, the faster decomposition rate of organic fertilizers leads to a decrease in soil organic matter content, which is not conducive to promoting the formation of soil aggregate structure. Therefore, in the face of sand, we have to pour water, or through drip irrigation, to maintain adequate residence time and supply of vegetable root moisture. Of course, we can also increase the ability to retain fertilizer and water retention by mixing the right amount of clay into the sand.
2 Clay: Clay should be watered as little as possible and watered. Clay is usually finer in soil and has better water and fertilizer retention capacity. The disadvantage is that the permeability of the soil is generally even poor; if the amount of water is not controlled, the moisture cannot be infiltrated in time and it is easy to cause roots. At the same time, after soaking in water for a long time, it is easy to form a knot crack after it is dried. If a large amount of hydration is needed, we should reasonably plow and accelerate the infiltration of water; then we must ridge and colonize, deep ditch irrigation, small water and water, and avoid flooding. In addition, it is necessary to enhance soil permeability by deep ploughing.
3 Loam: Loam is an ideal agricultural soil with the advantages of sand and clay. It has excellent ability to ventilate, keep warm, keep warm and tolerate cold, and is easy to cultivate for high-stable soil. So we can do a reasonable watering in the loam, and there are not too many precautions.
Different seasons, the amount of water to be treated will vary
There are four seasons in a year, spring, summer, autumn and winter. The climatic conditions and crop growth requirements of each season largely determine the difference in watering. The main difference is the summer and winter seasons. On the basis of the difference in soil quality, watering should be carried out as follows.
1 Summer: The weather is hot in summer, and the water evaporates faster and larger. In the face of sand, it is necessary to pour water; once it is found that the surface is dry, it should be replenished immediately. In the face of clay, it is necessary to shorten the interval between waterings reasonably, and to prevent the evaporation of water by preventing the soil compaction of the soil surface by cultivating and raking. It is important to remind everyone that clay sometimes has a dry surface and cracks, but it does not necessarily mean that it lacks water. For the summer watering of clay, you should observe the dry moisture of the soil about two centimeters below the surface before watering, in order to judge whether watering is needed, so as to avoid excessive pouring and causing roots.
2 Winter: The sand in winter is cooling fast, so it is not advisable to water too much. Excessive watering can cause the soil temperature to decrease too much, thus affecting the growth of vegetables. This should also be the case for clay, and the amount of water should be reduced reasonably.
