Green manure is an important organic fertilizer with comprehensive nutrients, stable fertilizer and long-term fertilizer efficiency. However, in the case of single application, the demand for nutrients in crop seedling growth is often not met in time. Fertilizer nutrients are single, fertilizer efficiency is fast and short. Single application can supply nutrients needed for crop seedlings in time, but de-fertilization will occur in the later stage. The effect of increasing yield is not obvious, and it is difficult to solve all the needs of crops, especially for soil comprehensive fertility. Although the nutrients provided by green manure are more comprehensive, it is not enough to meet the full demand of crops. At the same time, the nutrients provided by most green manure crops are mainly nitrogen, so it is necessary to apply them in combination with chemical fertilizers. The application of green manure and inorganic fertilizer should take into account the time and decomposing characteristics of green manure. At the end of summer and early autumn, the climate is mild and the soil moisture is appropriate. At this time, the green manure is decomposed and the mineralization speed is faster. At the end of autumn, the weather gradually cools down. The green manure decomposing and mineralization speed is slow. If this is based on the green manure pressure, a small amount of nitrogen and phosphorus fertilizer should be applied in combination with the spring sowing base to provide timely and sufficient nutrients for the crop seedling period. It lays a good foundation for its production and development, and can fully exert the fertilizer effect of green manure, which is consistent with the peak of fertilizer demand for crops, and has received obvious effects of increasing yield. The nutrients provided by most green manure crops are mainly nitrogen, especially legume green manure, so it is very important to supplement phosphorus and potassium fertilizers. However, it is best to supplement the phosphorus and potassium fertilizers when the green manure is planted. This can ensure the phosphorus and potassium needs of green manure growth, increase the fresh grass yield and quality of green manure, and the absorption and enrichment of phosphorus and potassium fertilizer by green manure. Improve the effectiveness of phosphorus and potassium fertilizers on post-crop crops, so as to achieve the goal of double-edged. In short, the combination of green manure and chemical fertilizers makes the fertilizer effect and fertility complement each other, which plays a role in the combination of land and land, and the coordination of fertilizer and fertilizer. It is an important measure to achieve weight loss and efficiency and sustainable green development in agricultural production.

Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
