1、Boron

Foliar application of B solutions is an efficient way to increase the B content of fruit trees. The efficiency of B uptake by fruit surfaces is lower than that of leaves and does not appear to be influenced by the presence of lenticels. Boron uptake through bark is negligible.

2、Soil boron fertilization: The role of nutrient sources and rootstocks

Soil B extracted with hot water and total leaf B positively correlated with doses of the nutrient applied to the trees. Levels of B in the soil and in the leaves did not vary with fertilizer sources. Fruit yield of trees grafted onto Rangpur lime and Swingle citrumelo was more responsive to B doses than those grafted onto Sunki mandarin.

3、Fertilizing Fruit Trees

All fertilizer bags are required to have the ration of Nitrogen, Phosphorus, and Potassium (N-P-K) on the label. A good N-P-K ratio for tropical fruit trees is where the first number, (N) is lower than the last number (K).

4、The Effect of Boron on Fruit Quality: A Review

Future research should focus on the application of boron nano-fertilizers to improve their efficiency in plant uptake and their impact on fruit functional disorders.

Boron in tree fruit and nut crops

Research has related boron concentration in leaves to fruit quality and fruit set. Fruit and nut crops need a constant supply of boron during all growth stages, especially during flowering, and nut and fruit development.

Fertilizing Fruit Trees

Check the percentage of boron in the product you buy. If it is 15%, reduce the rate by a third. If it is 20% boron, reduce the rate by half. Weigh the material to be sure you do not overapply as excessive boron can be toxic to trees. Fertilize pear trees according to growth and soil testing.

Discover the key to thriving fruit trees with our comprehensive guide on selecting the right fertilizer. Uncover vital nutrients like nitrogen, phosphorus, and potassium while learning to identify signs of deficiencies that hinder growth.

Boron in Soils and Plant Nutrition

Boron deficiency increases bud and flower drop, resulting in significant reductions in seed and fruit set, and also in the quality of developing fruits, nuts, and seeds.

Our findings revealed that endogenous boron content increased in early growth stages (S1 and S2 stages) following pre-flowering boron exogenous application. Boron treatment resulted in...

What Is the Best Fertilizer for Fruit Trees?

The soil test interpretation guides the selection of the fertilizer’s NPK ratio and the need for pH amendments. If the test indicates low phosphorus and potassium but adequate nitrogen, a ratio like 5-15-15 is more appropriate than a balanced 10-10-10 blend.

Fruit trees require both herbicides and boron fertilizers during their growth to ensure healthy development, improve fruit quality, and increase yield. Below is a detailed guide on the appropriate ratio of herbicide to boron fertilizer for fruit trees, along with proper application methods.

I. Use of Herbicides in Fruit Trees

1. Choosing the Right Herbicide

• Select herbicides based on the type of fruit tree, growth stage, and weed species. Specialized herbicides for fruit trees are recommended to minimize adverse effects on tree growth.
• Opt for environmentally friendly herbicides to avoid soil and ecosystem damage.

2. Proper Mixing Ratio

• Herbicides are typically diluted with water and sprayed onto weeds. Follow product instructions for dilution ratios.
• Example: For the herbicide "GreenBa" (绿霸), dilute it at a 500:1 ratio (e.g., 1 part herbicide to 500 parts water) and apply evenly to weeds.

3. Timing of Application

• Apply herbicides during early growth stages or peak weed activity for optimal results.
• Choose sunny, windless days to maximize effectiveness.

II. Use of Boron Fertilizer in Fruit Trees

1. Selecting the Right Boron Fertilizer

• Choose boron fertilizers based on tree nutritional needs and soil conditions. Organic fertilizers often contain higher bioavailable boron.
• Prioritize high-purity boron fertilizers for better absorption and efficacy.

2. Proper Mixing Ratio

• Boron fertilizers are usually diluted with water and foliar-sprayed. Adjust concentration based on tree requirements and soil type.
• Example: For "Rapid-Acting Boron" (速效硼), dilute it at a 2000:1 ratio (e.g., 1 part boron to 2000 parts water) and spray uniformly on leaves.

3. Timing of Application

• Apply boron fertilizers during peak growth stages and fruit maturation, when boron demand is highest.
• Apply on sunny, windless days for best results.

III. Integrated Application Methods

1. Alternating Application

• Rotate herbicides and boron fertilizers to prevent soil salinization and ensure balanced nutrition.
• Example: Schedule a gap period between herbicide and boron applications to allow trees to absorb nutrients effectively.

2. Dosage Control

• Follow recommended dosages on product labels. Adjust based on tree health and fruit quality:
  • Increase dosage if growth or fruit quality declines.
  • Reduce dosage if trees thrive.

3. Application Methods

• Apply near root zones for efficient absorption, as fruit trees absorb nutrients primarily through roots.
• Use modern irrigation techniques (e.g., drip or sprinkler systems) to enhance fertilizer uptake and improve fruit quality.

By following these guidelines, you can optimize the use of herbicides and boron fertilizers, promoting healthy fruit tree growth and maximizing yields. Mastering these techniques will help cultivate thriving orchards.
