Organic grapes are perennial plants that grow every year and result in the need to absorb large amounts of nutrients from the soil. In order to keep organic viticulture vigorously growing and continuously improve the yield and quality of organic grape products, we must pay attention to rational fertilization.
According to the determination of some organic grape production parks in our country, for each 100 kg of berry production, about 0.25-0.75 kg of organic nitrogen fertilizer, 0.2-0.75 kg of organic phosphorus fertilizer, and 0.13-0.63 kg of organic potassium fertilizer are needed.
All localities can adjust measures to local conditions and formulate suitable fertilizers through production practices and scientific experiments. According to the fertilization period can be divided into base fertilizer and top dressing. The basal fertilizer should be carried out after the fruit is harvested until the new shoot is fully matured at the end of September and early October.
The basal fertilizer is mixed with delayed fertilizers such as decomposed human urine or manure, poultry manure, green manure and phosphate fertilizer. Topdressing generally applies topdressing nitrogen fertilizers more than ten days before flowering, such as decomposed human excrement, cake fertilizers, etc., and in early July topdressing with potash fertilizers, such as grass ash and chicken manure. The fertilization method can be applied at a distance of about 1 meter from the plant to dig a circular groove, the base fertilizer has a depth of about 40 cm, and the top dressing should be lighter to avoid excessive rooting. Watering after fertilization.
Top dressing of organic grape roots has a significant effect on increasing yield and quality, and the method is simple and convenient. Spraying 1-3% of superphosphate solution before flowering, young fruit and berry ripening period has the effect of increasing yield and improving quality; Spraying 0.05-0.1% boric acid solution before flowering can increase fruit setting rate; Spraying 3% of the ash in the fruit growing period can increase the sugar content and yield of the berry. When organic liquid fertilizers are sprayed outside the root, in case of drought, the concentration should be reduced appropriately so as to avoid burning the leaves. In areas that have not been applied, it is advisable to try them out first, gain experience, and gradually promote them.
The streaming rearview mirror is a new type of rearview mirror, which can transmit the rear picture to the rearview mirror through the camera next to the high-mounted brake light at the rear of the car.
The surface is extremely clear, and it feels that the field of vision behind the car is expanded by 2 to 3 times. The field of vision is also good during driving, which greatly solves the problem of the blind spot of the C-pillar.
Compared with the general traditional rearview mirror, it can illuminate various scenes behind the rear of the car more clearly, and the viewing angle is also very wide. If you feel that the screen is reflective, just adjust the rearview mirror to a non-reflective angle, because the position of the camera remains unchanged, so the displayed content will not change.
Advantages of streaming rearview mirrors
â— Reduce visual blind spots
â— Enhance night vision capability
Disadvantages of streaming rearview mirrors
â— Fear of the "blinding" phenomenon of the rearview mirror caused by dirt, there are certain safety hazards
â— Imaging distortion, which is easy to cause the driver to misjudge the distance of the vehicle
Therefore, when purchasing, be sure to choose a streaming media rearview mirror with qualified quality and brand protection. Sanan is a professional car product manufacturer, a trusted partner!
