Trace Element Boron -Role in Crop Growth

Farmers focus on the use of organic fertilizers, macroelements and chemical fertilizers, but often ignore the supplement of trace elements. This article understands the role of boron on crops.

1. It can promote the formation and development of flower organs and improve the fruit setting rate.

Boron can stimulate the germination of pollen, promote the elongation of pollen tubes, and promote smooth pollination. The amount of boron in pollen is the largest in the stigma and ovary. If crops are deficient in boron, "flowers will not bloom", the anthers and filaments will shrink, and pollen will not form.

2. Increase the toughness between cells, promote the development of peel, make it smooth and delicate, and enhance the fruit quality.

According to relevant research, the fruit expansion period after the blooming period is also the peak period for fruit trees to need fertilizer. The fruit expansion period has a stronger ability to absorb boron. Using an appropriate amount of boron during the fruit expansion period can make the fruit skin develop smooth and delicate, and improve the fruit quality. .

Rough development of fruit trees, thickened and raised peels, swollen leaves, and hypertrophy of leaves, resulting in poor fruit quality, may all be caused by boron deficiency in fruit trees.

3. Improve the absorption of phosphorus, potassium, calcium, magnesium, iron, manganese and other elements by fruit trees

If crops are deficient in boron, it will not only affect the boron content in the crop, but also affect the absorption of other mineral elements, reducing the contents of phosphorus, potassium, magnesium, calcium, iron, zinc and manganese. For example, applying boron can bring the magnesium content in old leaves to a normal level. If boron is not supplemented adequately, magnesium will be severely deficient in old leaves.

Boron can also promote the differentiation of flower buds and promote the germination of autumn shoots. The autumn shoots will be neat and strong, fully accumulate nutrients, and avoid fruit bearing in different years.

4. Can increase plant stress resistance

Boron can promote the formation of vitamin C. The increase of vitamin C can improve the stress resistance of crops, thereby enhancing the crops' resistance to cold, drought, and disease. If crops are deficient in boron, their stress resistance and disease resistance will be weakened, which will also lead to a series of physiological diseases.

5. Promote cell division and elongation

Boron can promote the elongation and cell division of crop cells, which is beneficial to the growth and elongation of crop roots. If a crop is deficient in boron, it will inhibit the growth of the root tips and lateral roots of the crop, or even stop the growth in severe cases. Therefore, the density of the main root and lateral roots will decrease, which will affect the absorption capacity of the crop.

6. It can promote early maturity of crops and improve their quality.

Appropriate boron will shorten the spring flowering time of winter wheat by 8 days. When boron is applied to cotton, flowers increase before frost, and the grain yield and fiber quality are improved. An appropriate amount of boron will advance the main growth periods of corn and rice, and the seeds will mature about 5 days earlier. Appropriate use of boron can increase the protein content of rape; increase the vitamin content of cucumbers and tomatoes; increase the sugar content and reduce the acid content of apples and citrus.

7. Boron can promote the growth and development of root systems.

Boron can promote the sufficient supply of carbohydrates to rhizobia and promote the normal development of vascular bundles in the roots of leguminous crops. This can improve the nitrogen-fixing ability of leguminous rhizobia, increase the amount of nitrogen fixed, and increase the protein content. It can also increase the fiber content of hemp crops and improve their quality.

Boron can also regulate the formation and expression of organic acids in plants. If boron is deficient, organic acids will accumulate in the roots, which will inhibit the cell differentiation and elongation of the root apical meristem, cause corkization, and cause root necrosis.
