1. Nitrogen fertilizer: It can promote the growth of plant branches and leaves, enhance plant photosynthesis, increase chlorophyll content, and improve soil fertility.
2. Phosphate fertilizer: Promote the formation and flowering of flower buds, make plant stems and branches tough, mature fruits early, and improve plant cold and drought resistance.
3. Potassium fertilizer: Enhance plant stem, enhance plant disease resistance, insect resistance, and drought resistance, and improve fruit quality.
1、 The Role of NPK Fertilizer
N. P and K refer to nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer, and their functions are as follows.
1. Nitrogen fertilizer
(1) Enhance plant photosynthesis, promote plant branch and leaf growth, increase chlorophyll content, and improve soil fertility.
(2) If there is a lack of nitrogen fertilizer, plants will become shorter, their leaves will turn yellow and green, their growth will be slow, and they will not be able to bloom.
(3) If there is too much nitrogen fertilizer, the plant tissue will become soft, the stems and leaves will be too long, the cold resistance will be reduced, and it is easy to be infected by diseases and pests.
2. Phosphate fertilizer
(1) Its function is to make the stems and branches of plants tough, promote the formation and flowering of flower buds, make the fruits mature early, and improve the drought and cold resistance of plants.
(2) If plants lack phosphate fertilizer, they grow slowly, their leaves, flowers and fruits are small, and their fruits mature late.
3. Potassium fertilizer
(1) Its function is to make plant stems strong, promote root development, improve plant disease resistance, insect resistance, drought resistance, lodging resistance, and improve fruit quality.
(2) If there is a lack of potassium fertilizer, necrotic spots will appear on the leaf margins of plants, followed by withering and necrosis.
(3) Excessive potassium fertilizer leads to shortened plant internodes, shortened plant bodies, yellowed leaves, and in severe cases, death.
2、 What kind of fertilizer does NPK fertilizer belong to?
1. Nitrogen fertilizer
(1) Nitrogen is the main nutrient component of fertilizer, mainly including urea, Ammonium bicarbonate, ammonia, ammonium chloride, Ammonium nitrate, ammonium sulfate, etc. Urea is the solid fertilizer with the highest nitrogen content.
(2) There are various types of nitrogen fertilizers, which can be divided into nitrate nitrogen fertilizer, ammonium nitrate nitrogen fertilizer, cyanamide nitrogen fertilizer, ammonia nitrogen fertilizer, ammonium nitrogen fertilizer, and amide nitrogen fertilizer.
2. Phosphate fertilizer
The main nutrient of fertilizer is phosphorus, mainly including Superphosphate, calcium magnesium phosphate, phosphate rock powder, bone meal (animal bone meal, fish bone meal), rice bran, fish scale, Guano, etc.
3. Potassium fertilizer
Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, etc. Potassium sulfate, Potassium nitrate, Potassium chloride, Wood ash, etc.
