Grape "fall in love" organic fertilizer

During the grape production process, most of the nutrients are obtained from the soil. Zhang Zongqin, a professor at the College of Forestry, Northwest A&F University, said that it is now an important period for the use of organic fertilizers in grapes. When organic fertilizers and inorganic fertilizers are combined, they can truly achieve Grapes are high-yield, quality-enhancing and synergistic.

The application of deep-fertilization application of base fertilizer should be combined with deep tillage in the area where the roots are concentrated (the grape ditch is about 50cm from the root, the width of the ditch is 30~50cm, the depth is about 40~50cm) and the soil layer is often kept wet. In order to facilitate the integration of soil and fertilizer, it can play the role of fertilizing soil and supplying nutrients needed for crops.

Layered application of fertilizer In order to adapt to the continuous elongation of crop roots and the absorption of nutrients, the slow-acting fertilizer should be applied to the middle and lower part of the soil layer, and the quick-acting fertilizer should be applied to the upper part to achieve layered fertilization. Combination of late action and quick action.

Centralized application In order to improve fertilizer efficiency, a small amount of fertilizer is concentrated around the roots of the grapes (ditching or acupoint application) by means of ditching or hole application. For phosphate fertilizers, mixing with organic fertilizers and applying them centrally can reduce the contact area with the soil and prevent phosphorus from being fixed by the soil, thereby increasing the effectiveness of phosphorus.

Mixed application of various fertilizers to ensure that the crops continue to receive various nutrients throughout the growing period. It is best to use a combination of various fertilizers for organic fertilizers. “Organic fertilizer + bacterial fertilizer + compound fertilizer + trace element fertilizer”, first organic Fertilizer, add microbial fertilizer, mix well, add trace element fertilizer, stir well and finally add compound fertilizer.

Imported Premium Matting Powder

Matting powder is a new type of matting agent for leather repair made of polyacrylamide and film forming material. Used for repairing dark and light color surface and deep leather grain surface with strong covering power and good repairing effect. When used, it does not need to be used in combination with other soft peeling materials. It can be directly used for "brush coating" or "dot coating" repair, which simplifies the original use method. Manufacturing technology is simple, raw materials are easy to obtain, easy to form mass production and popularization application, to meet the needs of the leather industry. It can be divided into oily matting powder and water matting powder. It is widely used in emulsion paint, exterior and interior paint, alkyd resin paint and polyester paint systems. In the application of coating and paint, it can control the surface gloss of the film evenly, increase the wear resistance and scratch resistance of the film, dehumidify, deodorize, purify the air, sound insulation, waterproof and heat insulation, permeability.
