How to improve soil permeability
The increase of organic matter also promotes the increase of soil microbial activity. The activity of microorganisms loosens the soil and produces some substances that promote root growth, which is beneficial to the growth of the root system.
Second, rational watering reduces the damaging effect of watering on the soil. Traditional watering has a strong effect on soil erosion and compaction, and flood irrigation causes the air in the soil to be squeezed out and the granule structure of the soil is also destroyed, which is not conducive to the improvement of soil water retention and fertility. After watering, the surface of the soil is hardened and the permeability of the soil is reduced. It requires cultivating loose soil to break the compaction of the soil surface and restore the air permeability of the soil. After the greenhouse vegetable grows up, the cultivator loose soil can not be carried out, and the soil compaction is also unable to break.
Drip irrigation has the effect of protecting the soil. Drip irrigation is different from flood irrigation, it is to slowly hydrate the soil. In areas where drip irrigation such as Qingzhou has been promoted for many years, vegetable growers generally believe that the soil in the shed where drip irrigation is used is more porous and more air-permeable.
Again, diligently. After planting vegetables, pay attention to diligence, so that the permeability of the soil is good, it is conducive to the growth of vegetable roots. After the general vegetables are planted, they should be slaughtered every 3-5 days. And every time you pour water over it, you must scratch it. Pay attention to scratching can not be too deep, too deep soil easy to agglomerate, but it should not be too shallow, too shallow effect is not good, the general scratching depth to 3 - 5 cm is appropriate.
In addition, biological bacterial fertilizers are reused to increase microbial activity. After a long period of continuous cropping, harmful microorganisms in the soil are accumulated, and beneficial microorganisms are reduced. The application of biological fertilizer can regain advantage in the beneficial microorganisms in the soil. Moreover, many beneficial microorganisms themselves have the effect of improving the soil and improving soil permeability. Such as Mushi "stimulated antibacterial 968" or "big source to take root" 30-40 kg, not only can improve the soil physical and chemical properties and permeability, but also to improve the soil fertility, inhibition of vegetable root disease also has a significant effect.
Demetdent announced the release of the our company`s wet/dry milling machine. It was added to the Demetdent family of Dental Milling devices in answer to our lab and dental users need for a wet-milling option to handle many of the new brands and materials. The wet/dry milling machine fills a gap in many dental restoration workflows, giving laboratories the added flexibility of milling glass ceramic, composite resin materials that are becoming increasingly popular in the industry due to their high translucency, increased flexural strength and hardness, and overall aesthetic value for inlay/onlays.
