The combination of grape organic fertilizer and inorganic fertilizer is as follows:
Fertilization is the key to increasing production during the grape growing process. During the grape production process, most of the nutrients were obtained from the soil. Zhang Zongqin, a professor at the College of Forestry, Northwest A&F University, said that combining organic fertilizer with inorganic fertilizer can really achieve high yield, quality and efficiency.
Combined with the application of deep-fertilized base fertilizer, it should be combined with deep tillage in the area where the roots are concentrated (the grape ditch is about 50cm from the root, the ditch width 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 the 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 concentrated application 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 fertilizerâ€, first organic Fertilizer, add microbial fertilizer, mix thoroughly, add trace element fertilizer, stir well and finally add compound fertilizer.
