First, applying boron during the flowering stage can significantly improve fruit set rates in apples, pears, and peaches. It is recommended to spray a 0.3% to 0.5% borax solution early in the blooming period. This helps enhance pollination and increases the chances of successful fruit development.
Second, artificial pollination is an effective method to boost fruit set. By manually transferring pollen between flowers, you can ensure better fertilization, especially in conditions where natural pollinators are limited. This technique has proven to be highly beneficial, particularly for fruit trees that rely on cross-pollination.
Third, thinning and spacing fruits is essential to manage the tree's overall load. When branches have too many flowers or fruits, it can lead to poor growth and increased fruit drop. For trees with high flower density, it's important to remove some inflorescences to prevent overcrowding. Varieties with naturally high fruit set may need less thinning, while those with lower set should be thinned more aggressively. Bagging individual fruits can also help protect them from pests and diseases, ensuring better quality and higher yield.
Fourth, after flowering, fruit trees often experience nutrient depletion due to the energy required for fruit development and new growth. To counter this, applying urea fertilizer can help replenish nutrients and reduce physiological fruit drop. A 0.5% urea solution is typically sprayed once daily for about 10 days after flowering. This not only promotes leaf growth but also supports the tree’s ability to sustain more fruits.
Fifth, girdling or circular peeling of auxiliary branches can effectively reduce flower and fruit drop. However, care must be taken when performing this technique. The girdling should not be too wide—ideally, one-eighth to one-tenth the thickness of the branch. Girdling is especially useful for non-flowering saplings, as it encourages earlier flowering. It should be done before the tree starts flowering or before new shoots stop growing, depending on the desired outcome.
By combining these techniques, growers can significantly improve fruit set, reduce losses, and achieve better yields and fruit quality. Each method plays a unique role in supporting the tree’s health and productivity throughout the growing season.
Industrial Laser Distance Sensor
Industrial
Laser Distance Sensor, we also call it secondary development laser distance
module, which support TTL level and CMOS. The laser range sensor can be widely
used in professional surveying, mapping, construction, robots, hunting arrows,
industrial monitoring and automated measurement applications in electricity,
transportation, etc. Our laser distance module supports data communication with
RS232, USB with a simple adapter. The results of laser distance sensor can be
evaluated with Arduino. We are always looking ahead, hoping we can make every
measurement simple in life!
