Zhengzhou Grape Plantation uses plant nutrition analyzer to guide fertilization
In the process of grape growth, you need to ingest a sufficient amount of nitrogen, but the specific amount and when to supplement it, growers often do not have a standard. A grape farm in Zhengzhou uses a plant nutrition tester
to measure grape growth and guide fruit farmers to apply nitrogen fertilizer. .
We know that grape plants usually obtain nitrogen in the soil in the form of nitrate or ammonium nitrogen. Due to the new and slightly faster growth, the tree's demand for nitrogen is the largest between germination and flowering. Before flowering, the leaves must accumulate. More than 60% of the nitrogen in the year. At this stage, the tree is heavily dependent on nitrogen stored in the roots or trunk. When testing grapes at this point in time, how can we know the three major factors of the nitrogen content, chlorophyll content and leaf temperature of the vine at this stage, with these three factors, the grower knows what is missing in the grape growing process: Which factors, and how much to add. After being tested by the plant nutrient tester, growers became confident when fertilizing, and no longer worry about excessive nitrogen caused by excessive fertilization and low grape fruit setting. And with the plant nutrition tester, growers can perform non-destructive testing at any time, without affecting the vines, and always knowing it. >>>> Recommended reading: Which is the real effect of nitrogen, phosphorus and potassium on plants?
It is reported that grape growers have repeatedly used plant nutrition testers to
find that in the management of grape nitrogen nutrition, the young fruit expansion period and post-harvest fertilization are the two most critical nitrogen fertilizer application periods. After the flowering seat is stabilized, it is at this time that the young fruit swells, the new growth and the flower bud differentiation require nitrogen supply. After harvesting, fertilize and reserve enough nutrients to provide sufficient nutrients for new growth in the coming year.
