1、Identifying immature and mature pomelo fruits in trees by elliptical model fitting in the Cr–Cb color space

In precision agriculture, identification of fruit in trees is important. Furthermore, it is also essential for estimating the yield, targeting the exact location for a harvesting robot and selectively harvesting the fruit.

2、Fertilizing Fruit Trees

Fruit trees are fertilized to ensure continued growth and fruit production. In the backyard orchard, proper pruning in addition to the application of nitrogen in the spring prior to or at bud break helps maintain this productive status. Other than nitrogen and zinc, iron and manganese may limit growth due to our alkaline soil conditions.

5、Fine root biomass and dynamics in beech forests across a precipitation gradient – is optimal resource partitioning theory applicable to water

Optimal resource partitioning theory predicts that plants should increase the ratio between water absorbing and transpiring surfaces under short water supply.

Planting Landscape Trees

Even if the soil is moist at the time of planting, thor-oughly irrigate the tree to settle the soil around the root system. Remember that most of the root volume occupies a rather limited area, particularly through the first growing season.

Optimal Giving

Krebs et al. (1974) predicted that an optimal forager in a patchy habitat should apply the same giving-up time (GUT) to all patches, even if they differ in quality.

Evaluation of the physicochemical and textural properties of pomelo fruit following storage

Because of the long transportation times and storage durations that are often experienced, it is important to understand how pomelo properties change over time; that will be indicative of how long samples can be stored before they drop below acceptable quality limits.

Optimum harvesting time and clone choices for eucalyptus growers in Vietnam

In the first section of the paper, timber yield functions for all eucalyptus monoculture clones and seedlings are identified. Next, the biological optimum rotation period for maximizing sustained yield is calculated based on the yield functions for each soil type.

Optimal Tree for Both Synchronizability and Converging Time

In addition, we present a simple and universal way to get such an effective oriented tree in a given network to reduce the converging time significantly by minimizing the depth of the tree.

The timing of fertilization for pomelo trees depends on their growth cycles and soil conditions. In spring, as temperatures rise, pomelo trees enter a new growth phase. Fertilizing during this period promotes the development of new branches and flower bud formation. During summer, when temperatures are high, the tree’s growth accelerates, and fertilization provides essential nutrients to help it thrive through hot weather. In autumn, as temperatures drop, the tree prepares for dormancy; fertilizing at this stage supports fruit ripening and enhances cold resistance. Winter, marked by low temperatures and dormancy, requires fertilization to sustain the tree’s nutrient reserves and aid survival in chilly conditions.

1. Spring Fertilization Spring is critical for pomelo tree growth. Fertilizing before budding stimulates new branch development and flower bud formation. Apply organic or compound fertilizers as directed on the product label.

2. Summer Fertilization Summer is another key growth phase. Fertilize before heat peaks to ensure adequate nutrients for the tree. Use organic or compound fertilizers following package instructions.

3. Autumn Fertilization After leaf fall in autumn, fertilization supports fruit maturation and cold hardiness. Apply organic or compound fertilizers as recommended.

4. Winter Fertilization Before winter arrives, fertilize to strengthen the tree’s nutrient reserves for surviving low temperatures. Organic or compound fertilizers should be applied according to guidelines.

5. Fertilization Methods Two primary methods are used:

• Base fertilization: Applied during planting, providing long-term nutrients.
• Topdressing: Done during growth, divided into:
  • Foliar spraying: Dissolved fertilizer sprayed onto leaves.
  • Root fertilization: Dripped around the root zone.
  • Branch fertilization: Injected into trunks or branches.

6. Key Considerations

• Amount: Avoid over-fertilization, which can damage the tree.
• Timing: Adhere to optimal seasons; premature or delayed fertilization may harm growth.
• Method: Match techniques (e.g., foliar vs. root) to肥料 type and tree needs.

proper fertilization is vital for healthy pomelo trees. By aligning practices with seasonal needs and scientific methods, growers can maximize growth and yield.
