Different age of seedlings, staged fertilization
First, the new planting seedlings can be opened first, the hole width is 30-50 cm, the depth is 20-25 cm, and the base fertilizer is applied in the hole; the second is the old seedling planted for more than 15 years. Because the plant is aging, the flower bud is thin and bud. Shaolei is small and needs to be renewed. After excavating the old and weak seedlings, the organic fertilizer is applied. Third, the conventional seedlings should be applied with spring seedling fertilizer, moisturizing fertilizer and autumn fertilizer.
Scientific formula, balanced fertilization
In order to make the daylily grow stronger and prevent disease invasion, it is necessary to pay attention to scientific formula and balance fertilization. First, use decomposed organic fertilizer such as human excrement, column manure, compost; second, refined active organic compound fertilizer, such as Hui Manfeng, Di Le Dan, etc.; third is high-energy organic compound fertilizer; fourth is inorganic nitrogen, phosphorus and potassium fertilizer. The first three kinds of fertilizers are mainly used as base fertilizer and spring seedling fertilizer; at the same time, inorganic fertilizer is applied. Spring seedlings are combined with 10 kg of nitrogen fertilizer and 7 kg of potassium fertilizer; the fertilizer is applied with 10-15 kg of fertilizer per acre; the autumn fertilizer advocates the application of human excrement, 500-750 kg per mu, and the appropriate amount of phosphorus and potassium fertilizer. At the same time, after 10 days of harvesting the flower buds, root spray fertilizer should also be carried out.
Cultivate soil and water
The stable harvest period of daylily is more than 15 years. After harvesting or after heavy rain, it is easy to tie the knot, especially the soil with poor soil is more likely to be knotted, which affects the absorption of fertilizer by yellow flowers. Therefore, during the growth period of yellow flowers, it is necessary to diligently cultivate the loose soil, and before the emergence of the flower to the flower buds, it should be shallow for 3 to 4 times. After the buds are harvested, they should be deeply ploughed to create a loose environment and improve the ability to retain fertilizer and water. It is necessary to combine fertilization with cultivating and reduce the loss of fertilizer. Third, in the case of drought, timely watering should be done to adjust fertilizer with water and improve fertility.
Ball bearings consist of a series of round balls in a casing, within an inner and outer ring capable of supporting both radial and axial (thrust) loads. Ball bearings come in both single and double row configurations, in both metric and inch sizes, and can be found in a large range of applications from door hinges to roller skates.
Types of Ball Bearings
There are a number of different types of ball bearings, such as miniature, deep groove, and super precision.
Miniature Ball Bearings are small bearings with bore sizes between 1 and 10 mm or up to half an inch. Bearings Direct offers a number of miniature ball bearings in both metric and inch sizes that meet ABEC7 precision class.
Deep Groove Ball Bearings are incredibly versatile and the most widely used. Due to their low friction, they are capable of high rotational speeds, supporting both radial and axial loads. Bearings Direct offers both in metric and inch sizes , also we stock stainless steel made materials metric and inch sizes
Super Precision Ball Bearings are specifically designed with accuracy in mind for high-speed and precision applications. They are capable of high rotational speeds with low friction and noise.
Precision Angular Contact Ball Bearings carry combined loads, both radial and axial, designed, much like the super precision bearings, for high-speed and high-precision applications.
Double Row Ball Bearings are similar to both precision angular contact and super precision ball bearings in that they can accommodate a combined radial and axial loads. These bearings have two rows of balls inside making them capable of much higher loads. Bearings Direct supplies double row ball bearings that are open and with shielded or sealed closures.
Self-Aligning Ball Bearings are double-row ball bearings that can adapt to both static and dynamic angular misalignment. These bearings are particularly appropriate when shaft and housing alignment is a challenge.
Thrust Ball Bearings are ball bearings that can carry axial loads alone. Bearings Direct supplies thrust ball bearings that are single row, in both miniature and regular three-piece configurations.
Bearings Direct supplies all of these ball bearings and you can browse our inventory and purchase online using the links below.
