1、Harnessing biological nitrogen fixation in plant leaves
The importance of biological nitrogen fixation (BNF) in securing food production for the growing world population with minimal environmental cost has been increasingly acknowledged. Leaf surfaces are one of the biggest microbial habitats on Earth, harboring diverse free-living N 2 -fixers.
2、Mixed nitrogen forms enhance growth and photosynthetic nitrogen use
The leaf N distribution affects leaf growth, the chlorophyll content, and the intensity of photosynthesis. Therefore, understanding changes in leaf N distribution is significant for improving N efficiency and reducing N fertilizer input. Due to its yield-increasing effects and relatively low price, farmers often overuse N fertilizer in production.
3、Controlled
Controlled-release fertilizers (CRF) have been reported to effectively reduce the nitrogen loss by matching the release pattern with crop N demand, thus increasing the yield. However, the changes in N allocation to enhance the photosynthesis under CRF have rarely been addressed.
Optimizing nitrogen fertilizer for improved root growth, nitrogen

How Does Nitrogen Affect Plant Growth? A Complete Guide
Without enough nitrogen, chlorophyll production drops, leaves turn yellow (a sign called “nitrogen deficiency”), and photosynthesis slows. With sufficient nitrogen, leaves stay deep green, maximizing energy production for growth.
Harnessing biological nitrogen fixation in plant leaves
Leaf surfaces are one of the biggest microbial habitats on Earth, harboring diverse free-living N 2 -fixers. These microbes inhabit the epiphytic and endophytic phyllosphere and contribute significantly to plant N supply and growth.

After N is absorbed and utilized by plants, it plays important regulatory roles in phytohormones, microRNA (miRNA), root development and mycorrhizal symbiosis to cope with environmental stress....
Nitrogen fertilizer is one of the essential fertilizers in the process of plant growth, playing a crucial role in promoting lush stems and leaves. Nitrogen fertilizer can increase the content of proteins and nucleic acids in plants, enhance their photosynthetic and respiratory capacities, thereby promoting the growth of stems and leaves. The following sections will elaborate on the reasons why nitrogen fertilizer promotes lush stems and leaves.
- Effects of Nitrogen Fertilizer on Photosynthesis
Nitrogen is an important element in the composition of proteins, which are key enzymes involved in the entire process of photosynthesis. Under light conditions, nitrogen fertilizer can promote the synthesis of chlorophyll in plant leaves, increasing chlorophyll content, and thus enhancing the efficiency of photosynthesis. Chlorophyll is the primary pigment used by plants for photosynthesis, absorbing light energy and converting it into chemical energy, providing the necessary energy for plant growth. an increase in nitrogen fertilizer helps improve the photosynthetic capacity of plants, promoting the growth of stems and leaves.
- Effects of Nitrogen Fertilizer on Respiration
Nitrogen fertilizer can increase the respiration rate within plants, enhancing their respiratory activity. Respiration is the process by which plant cells break down organic matter to release energy for vital activities, and it also plays a significant role in the material cycle within plants. By increasing the respiration rate, nitrogen fertilizer provides more energy, enabling plants to better carry out photosynthesis and growth. Additionally, nitrogen fertilizer can increase the sugar content within plants, facilitating smooth respiration.
- Effects of Nitrogen Fertilizer on Root Growth
Nitrogen fertilizer promotes the growth of plant roots, expanding the root system's absorption area and enhancing its ability to absorb water and nutrients. Roots are the main organs for absorbing water and nutrients from the soil, and a well-developed root system can effectively improve the plant's nutrient utilization efficiency. When there is an adequate supply of nitrogen fertilizer, plants prioritize using nitrogen for root growth, thereby ensuring that stems and leaves receive more nutrient supplies.
- Effects of Nitrogen Fertilizer on Transportation and Distribution of Nutrients
Nitrogen fertilizer can promote the transportation and distribution of nutrients within plants. After being absorbed by plants, nitrogen from fertilizers is transported through the xylem to the stems and leaves, promoting their growth. nitrogen fertilizer can regulate the transportation and distribution of other nutrients within plants, ensuring that stems and leaves receive more nutrients. For example, nitrogen fertilizer can promote the accumulation of potassium, phosphorus, and other nutrients in stems and leaves, improving their growth quality.
- Effects of Nitrogen Fertilizer on Plant Hormone Balance
Nitrogen fertilizer can influence the synthesis and secretion of various hormones within plants, thereby affecting their growth and development. Hormones such as auxins and gibberellins play important roles in the growth of stems and leaves. Nitrogen fertilizer can affect the synthesis and secretion of these hormones, regulating plant growth and development. For instance, an appropriate amount of nitrogen fertilizer can promote the synthesis of auxins, enhancing the growth of stems and leaves; excessive nitrogen fertilizer may inhibit auxin synthesis, leading to poor growth of stems and leaves.
- Effects of Nitrogen Fertilizer on Plant Stress Resistance
Nitrogen fertilizer can improve a plant's stress resistance, enabling it to better adapt to environmental changes. Nitrogen fertilizer can enhance a plant's resistance to cold, drought, diseases, and other stresses, allowing it to maintain good growth under adverse conditions. For example, under adverse conditions such as drought or cold, an appropriate amount of nitrogen fertilizer can improve the plant's stress resistance, promoting the growth of stems and leaves.
nitrogen fertilizer promotes lush stems and leaves through multiple pathways. It can improve photosynthetic efficiency, enhance respiration, promote root growth, improve the transportation and distribution of nutrients, affect plant hormone balance, and improve stress resistance. the rational application of nitrogen fertilizer is of great significance for promoting lush stems and leaves in plants. In actual agricultural production, nitrogen fertilizer should be applied reasonably according to crop requirements and soil conditions to achieve the best fertilization effects.
