How to Improve Soil Permeability?

First, reduce the amount of chemical fertilizer, according to soil testing results, the total salt content in the soil is controlled below 2.0 g / kg, which can effectively alleviate soil compaction.


Second, deepen the soil, deepen the tillage layer, and enhance the cushioning and permeability of the tillage layer. The root system of vegetables is generally distributed in the soil layer of 25-30 cm, while the ordinary rotary tiller can only turn over 12-15 cm. The vegetable grower can use the shovel to deepen the shovel after the rotary tiller has turned the ground, deepening the bottom of the plough to 25-30 cm to increase the depth of the tillage layer and increase the air content in the soil. Of course, it is best for the vegetable growers to make a deep turn every three years, and the depth of the vegetable is 30-50 cm deep to break the original plow floor and promote the deep rooting of the vegetable roots.


However, for different types of soil, the requirements for the depth of the plow layer are different. For example, sandy loam soil, due to large soil particles and good soil permeability, is also prone to water leakage and leakage. For such soil, vegetable farmers can use the spin for many years. The tiller turns over the ground to keep water and fertilizer. For clay land, it is recommended that vegetable farmers do not use a rotary tiller to turn the ground. Instead, the soil in the greenhouse should be turned deep before each vegetable is planted. The depth of the soil is 30 cm.


Third, pay attention to reasonable watering. Water and gas are relatively contradictory. When the water is large, the gas in the soil will be squeezed away, which will inevitably lead to poor gas permeability. Therefore, the watering of vegetables should be paid attention to the amount of watering should not be too large, avoid flooding, conditional It is best to use micro-irrigation or drip irrigation to make the water slowly infiltrate into the soil, so that the soil has less tamping effect and is beneficial to improve the permeability of the soil. At the same time, after watering, pay attention to timely ploughing and slashing, and help increase the permeability of the soil.


Fourth, in order to avoid the soil in the vegetable operation, it is best to use straw covering, which not only ensures the soil is well ventilated, but also ensures that the ground temperature is constant, and also has the effect of absorbing moisture in the shed.


Fifth, when covering the mulch film, the film must be propped up to prevent the film from sticking to the ground and affecting the permeability of the soil.
