In recent years, there have been some prominent fertilization problems in the production of strawberry bases. Due to the shallow strawberry roots, they have resulted in successive results. Therefore, during the growth process, the demand for nitrogen fertilizer is very large. Due to lack of scientific management, nitrogen fertilizer abuse appears in strawberry bases. The problem. Although the effect of nitrogen fertilizer on strawberry production is significant, it is within a reasonable range. If nitrogen fertilizer is applied excessively, it will not only cause low utilization rate of nitrogen fertilizer and waste of resources, but also cause a series of environmental conditions such as deterioration of field ecological conditions and groundwater pollution. The problem is to limit the green development of the strawberry base. Therefore, in order to improve this unreasonable fertilization, some strawberry bases have begun to use portable chlorophyll meter to guide scientific fertilization.
The portable chlorophyll meter mainly determines the chlorophyll content in the leaves. It seems that there is no close relationship between the instrument and scientific fertilization, but we can know that the nitrogen is a nucleic acid, a coenzyme, a phospholipid, a chlorophyll, a cytochrome by understanding the effects of the nitrogen fertilizer. Components such as phytohormones (CTK) and vitamins are important elements involved in the formation of chlorophyll. Appropriate application of nitrogen fertilizers has a significant effect on improving crop photosynthesis. In general, nitrogen deficiency in plants is also the biggest and most intuitive effect on the leaves. Therefore, the determination of chlorophyll content is mainly used to monitor the nitrogen content of plants and to understand the nitrogen status of crops, thus guiding farmers to apply scientific fertilization.
After applying the portable chlorophyll meter for scientific monitoring at the Strawberry Base, the management of fertilization in the base became more scientific and rational. It not only satisfied the demand for nitrogen fertilizer during the growth of the strawberry, but also improved the yield and quality of the cultivation, and significantly improved the utilization rate of nitrogen fertilizer. Reduced fertilizer costs. At the same time, scientific fertilization also solved the problem of nitrogen fertilizer pollution and created a healthy and ecological environmental condition for the growth of strawberries. It is of great significance for the strawberry base to carry out ecological cultivation and achieve green development.
