Goji berry (Lycium barbarum), as a widely recognized "health-preserving" medicinal herb, is extremely popular in China. At present, the goji berry planting area in China is also very large, and when growing goji berries, work such as watering and fertilizing is very important. When fertilizing, we not only fertilize the roots, but the work of foliar topdressing outside the roots cannot be ignored either. So what are the benefits of topdressing foliar fertilizer on goji berry? Let's take a look together with the editor below!

1. Simple application

When topdressing with foliar fertilizer, its application method is far simpler than traditional fertilization. Foliar fertilizer can be directly diluted with water and sprayed, which is more convenient than soil application. Foliar fertilizer is mainly based on substances such as urea, and after spraying the urea solution onto the tree canopy at a temperature environment of around 25°C for about 10 minutes, its nitrogen element can be fully absorbed by the leaf stomata, which can effectively improve the absorption and utilization rate of the foliar fertilizer. The leaf mesophyll can also meet a sufficient absorption amount, and the nutrient absorption speed is far faster than soil application.

2. High utilization rate

In traditional soil fertilization methods, the utilization rate of fertilizer has always been a problem that has not been handled well. Foliar topdressing can effectively solve this. When spraying foliar fertilizers such as monopotassium phosphate or urea, if testing is carried out after about one hour, it can be found that the utilization rate of the potassium element in monopotassium phosphate can reach more than 75%, and the absorption duration can last for about two hours. But if traditional soil fertilization methods are used, then its utilization rate is only about 35%.

3. Supplementing nutrition

Reasonable foliar topdressing can supplement the trace elements lacking in goji berry plants. Especially when goji berry plants suffer from natural disasters or insect pests, spraying foliar fertilizer can promptly make up for the lost nutrition. Every spring, because the soil's nutrients are limited, the growth nutrition of goji berry is insufficient, and at this time urea can be appropriately sprayed to ensure the normal growth of goji berry. And in summer, during the peak growth period of goji berry, spraying foliar fertilizer can achieve the purpose of assisting fruit setting and slowing flower and fruit drop. If sprayed in autumn when the temperature is relatively low, it can also improve the safe overwintering rate of goji berry plants.

4. Meeting nutritional needs

Goji berry has a very large demand for nutrition during its growth process. Especially in the early and late stages of growth, because goji berry is affected by factors such as temperature and environment during the early and late growth stages, the absorption by the root system may not be able to meet the nutritional needs of goji berry growth, so we should pay attention to appropriately spraying foliar fertilizer. It can not only enhance the tree vigor of goji berry plants, but also increase yield and the quality of goji berry fruits. However, it should be noted that foliar fertilizer cannot completely replace soil fertilization; spraying and application should be combined to ensure the normal growth of goji berry.

The above is a brief introduction to the benefits of topdressing foliar fertilizer on goji berry. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
