Roots play a vital role in crop development and healthy growth. The greenhouse vegetables will be transplanted and planted in the production process. After transplanting, the seedlings will be damaged from the comfortable seedbed to the deteriorated soil, the roots will be damaged, the growth will be insufficient, and the seedlings will not be provided with sufficient water and nutrients. The seedlings will be damaged by the transplanting pressure. It seriously affects the rapid growth of slow seedlings and subsequent plants. At this time, it is the most important period of root growth and development in the crop growth cycle. The development and progress of roots after transplanting will play a decisive role in the whole growth stage of crops. Therefore, how to promote the rapid growth of roots after transplanting and choose a good rooting product is a strong practical demand for greenhouse growers.
to sum up:
1. Before and after transplanting greenhouse vegetables, it is the most important stage to construct its root system.
2. If the root system is damaged due to temperature and soil environmental stress in the middle and late stages of crop growth, it is necessary to guide the rooting again instead of excessive rooting.
In the management of greenhouse vegetables, is my rooting product selected correctly?
The products that promote rooting are everywhere in the market. Many of the quick-acting products add a large amount of growth regulator components. The new roots induced by these products lack capillary roots, and the working ability is weak, which is prone to obvious early rooting. Premature aging is a serious phenomenon.
While auxin is often in the dynamic balance of synthesis and decomposition in crops, it promotes crop growth at a suitable concentration. If the concentration is too high, it will inhibit growth. When the content of auxin is too high, it will stimulate auxin synthase. Increased activity, degradation of auxin into a bound state, such as acetoacetyl aspartate, indoleacetic acid-protein complex; when under suitable conditions, under the action of auxin aminohydrolase, converted to free state Auxin, transport transfer to the site of action.
Products containing growth regulators have many problems in the actual use process by controlling the concentration of auxin raw materials, resulting in no obvious rooting or no use of roots.
Therefore, when choosing a rooting product, you must choose a product that can provide nutrition to the crop without breaking the metabolic disorder caused by the inherent regulation of the crop.

Bearing housings are modular assemblies designed to make it easy to install bearings and shafts, while protecting bearings, extending their operating life and simplifying maintenance.
Housings are available in many sizes, and generally fall into five standard categories: split plummer (or pillow) block housings, non-split plummer block housings, flanged housings, take-up housings and two-bearing housings. These products can be designed to meet specific duty requirements such as load, speed and operating environmental conditions.
Non-standard bearing housing designs can also be supplied to particular customer requirements: for example, where special shaft centre heights, unusual sealing arrangements or non-standard materials of construction may be specified.
If ease of installation and maintenance are prime considerations, then split plummer block housings are an excellent choice as they not only accommodate pre-assembled shafts, but also simplify bearing inspections and maintenance as the shaft does not need to be disassembled. These units are designed for self-aligning ball bearings, spherical roller bearings and CARB toroidal roller bearings. Non-split plummer block housings are preferred when there are heavy loads acting in a direction other than toward the support surface. They are also used when the housing has to be mounted from the end of the shaft.
We have specialized in producing US/EURO standard bearing housings more than 10 years, could help to design the bearing housing or produce the bearing housing according to your requirements. (OEM accepted)
