The emergence of intensive management techniques such as the continuous increase in the demand for timber, the reduction of fertilizer costs, the short rotation period and the use of whole trees due to the recovery and development of early economies has made the fertilization of forest trees an indispensable part of the establishment of fast-growing high-yield plantations. Basic technical measures. Analysis of leaf leaves Forest nutrients need to be the result of lagging economic development in the past decade. The main representative is the portable chlorophyll meter. The use of chlorophyll meter for tree nutrient diagnosis has become an important means to guide tree fertilization. Surveillance methods have been used since their initial use, and are recognized as more mature methods.
Because of its long-period nature, forest trees have a more profound content and meaning than their crop counterparts. Not only do they change with forest species, yield levels, harvesting systems, soil types, fertilization methods, fertilizer levels, management levels, and climatic factors. Different, and change with time and space, under different conditions have different balance systems. Therefore, in order to realize balanced fertilization of forest trees, it is necessary to understand that the maximum yield of forest trees is the maximum value of nutrients required, as well as the potential existence of limiting factors, and the measurement and analysis of the chlorophyll content of plant leaves by chlorophyll meter can help. We conduct reasonable guidance on the amount of nitrogen fertilizer application. Nitrogen is one of the necessary elements in the growth process of forest trees. Using the chlorophyll meter is very helpful in judging the shortage of nitrogen in forest trees. It is found through experiments that the use of chlorophyll meter is used as a guide. Fertilization can help to reduce nitrogen fertilizer use by 10%, while ensuring that crop yields do not decrease.
At present, only the chlorophyll meter can detect the chlorophyll content of the leaves. The chlorophyll meter developed and produced by Top Instrument is based on near-infrared spectroscopy non-destructive testing methods to measure chlorophyll. In addition to measuring the chlorophyll content of the leaves, the temperature of the leaves can also be analyzed. Through the analysis of nitrogen content, scientific guidance of farmers to fertilize.
