China has established a new fertilizer network tailored to its wheat production regions, which are divided into five major areas based on geographical and agricultural conditions: the Northeast Spring Wheat Region, the Northwest Wheat Region, the North China Winter Wheat Region, the Middle and Lower Reaches of the Yangtze River Winter Wheat Region, and the Southwest Wheat Area. These regions are further subdivided into seven sub-regions, covering 99% of the national wheat area. Here's a detailed breakdown:
1. **Northeast Spring Wheat Region**: Includes parts of western Heilongjiang and northeastern Inner Mongolia.
2. **Northwest Rain-Fed Wheat Area**: Covers northern Hebei, northern Beijing, southern Wulanchabu in Inner Mongolia, most of Shanxi, northern Shaanxi, western Henan, northern Ningxia, and eastern Gansu.
3. **Northwestern Irrigated Wheat Area**: Spans central Inner Mongolia, northern Ningxia, central and western Gansu, eastern Qinghai, and Xinjiang.
4. **North China Irrigated Winter Wheat Region**: Encompasses Shandong, Tianjin, central and southern Hebei, central and northern Henan, Guanzhong Plain in Shaanxi, and southern Shanxi.
5. **North China Rain-Fed Winter Wheat Area**: Located north of the Huaihe River in Jiangsu and Anhui provinces, as well as southeastern Henan.
6. **Middle and Lower Reaches of the Yangtze River Winter Wheat Region**: Includes Hubei, Hunan, Jiangxi, Zhejiang, Shanghai, and southern parts of Henan, Anhui, and Jiangsu.
7. **Southwest Wheat Area**: Covers Chongqing, Sichuan, Guizhou, Yunnan, and southwestern Shaanxi.
Fertilization recommendations vary by region and yield level. For example, in the **Northeast Spring Wheat Area**, recommended formulas include 12-20-13 (N-Pâ‚‚Oâ‚…-Kâ‚‚O) or similar. Fertilizer application depends on the expected yield, with different rates for low, medium, and high productivity levels.
In the **Northwest Rain-Fed Wheat Area**, the recommended formula is 28-12-5 (N-Pâ‚‚Oâ‚…-Kâ‚‚O), applied as a base fertilizer depending on yield potential. For **Northwest Irrigated Wheat Areas**, the formula 17-18-10 (N-Pâ‚‚Oâ‚…-Kâ‚‚O) is advised, with additional urea applications during key growth stages.
The **North China Irrigated Winter Wheat Area** recommends 15-20-12 (N-Pâ‚‚Oâ‚…-Kâ‚‚O), while the rain-fed winter wheat area offers both base-chasing and one-time fertilization options, such as 18-15-12 or 25-12-8 (N-Pâ‚‚Oâ‚…-Kâ‚‚O).
For the **Middle and Lower Reaches of the Yangtze River**, two formulas are suggested: 12-10-8 (low concentration) and 18-15-12 (high concentration). The **Southwest Wheat Area** also provides options like 12-10-7 and 19-15-11 (N-Pâ‚‚Oâ‚…-Kâ‚‚O), tailored for varying yield levels.

Metal Bond Cutting Wheels
Resin diamond cutting resin is a kind of abrasives and tools made of low temperature curing binder. Features: cutting processing, low calorific value, good self-sharpening, not easy to block, high surface finish of processed workpiece. Application: used in optical glass, glass tube, glass rod, quartz glass, glass fiber, semiconductor, hard alloy, ceramics, zirconia ceramics, circuit board (PCB) and other hard and brittle materials cutting or slotting.
It is mainly used for cutting or grooving ordinary glass, glass rod, glass Mosaic, ceramic plate, sapphire, stone slotting, semiconductor material, brake pad and other materials.
Advantages of electroplating diamond products ①Electroplating process is simple, less investment, convenient manufacturing; No need to repair, easy to use; The single layer structure determines that it can reach a very high working speed, which has been as high as 250 ~ 300m/s abroad; (4) Although there is only a single diamond, it still has enough life; ⑤ For roller grinding wheel with higher precision requirements, electroplating is the only manufacturing method.
Because of these advantages, high speed and ultra-high speed grinding with electroplated wheel occupies an undisputed dominant position.
