Few Fruits on Pear Trees? Here Comes the Latest Solution

In recent years, the pear planting area in our country has increased, so pear production has also improved to a certain extent. But many people are asking why some pear trees have a very low fruit set rate, resulting in low yields every year, and whether there is a solution. In fact, there are many reasons for low fruit set in pear trees. As long as adjustments are made according to different situations, the fruit set rate can be improved. Below are some solutions for improving the fruit set rate made by Qinnong.com according to different situations. We hope they can help everyone.

1. Improve planting conditions

The environment suitable for pear tree growth is generally flat land with relatively fertile soil. Of course, it can also be mountainous land, but we need to improve its growing environment. First, we must ensure that the soil of the planting site is relatively loose. Second, increase the nutrients in the soil. Third, the temperature suitable for pear tree growth is around 25 degrees, and the lowest temperature cannot be lower than 10 degrees, so we need to manage temperature. The field moisture cannot be too much, as it will cause pear trees to develop disease. The soil temperature should be kept at around 55.

2. Reasonable matching of pollinator trees

Sometimes you may feel that the pear trees bloom especially heavily, but in the end the fruit set rate is not ideal. That is caused by unreasonable matching of pollinator trees. So when planting pear trees, it is best to plant them in a herringbone pattern. This is more conducive to pollination during the flowering season. This planting method is very beneficial to insect pollination and mutual pollination between pear trees, and can basically ensure an 80 percent pollination rate. In this way, the phenomenon of low fruit set rate is basically solved.

3. Scientific fertilizer and water management

When planting, sufficient base fertilizer needs to be applied, which can lay the foundation for high yield. Second, fertilizer and water management during the seedling stage is also relatively important. We mainly use urea to promote the growth and development of the fruit trees. Then for mature fruit trees, we should pay even more attention to management in fertilizer and water. Fertilization is needed once every spring, mainly to let the pear trees sprout quickly and enter the flowering stage. Second, when flowering begins, we should apply more phosphorus fertilizer, mixed with an appropriate amount of compound fertilizer. Water management at this time is also very important. If there is too little water, it will cause flower drop, so there must be sufficient water. After fruit set, we need to increase the application of potassium fertilizer and boron fertilizer. This is beneficial for fruit retention and can reduce fruit drop, so that the fruits truly survive.

4. Artificial supplementary pollination

In many cases, low fruit set is basically caused by uneven pollination or pollination not being completed properly. So we can carry out artificial supplementary pollination to improve the fruit set rate. On a sunny day two days after pear flowers bloom, we can collect the pollen, then after treatment with a medicinal solution, leave it for one day. Then at eight o'clock the next morning, we can go to the field for artificial pollination. The pollination method can use equipment for spraying, and can also be applied manually. No matter which method is used, pollination must be even. Only in this way can the survival rate be improved.

5. Reasonable flower and fruit thinning

Under normal circumstances, pear trees bloom relatively heavily every year, and the influence of various external factors is also relatively small, so small fruits with good fruit set will appear all over. But if flower and fruit thinning are not carried out, many pears will not grow large, and deformed fruit will appear. In severe cases, this can cause no flowering the next year. So we need to carry out flower thinning and fruit thinning. The best way to thin flowers is to remove the central flower of the fruit tree and keep the flowers beside it. The best way to thin fruit is to keep one fruit every 15 to 20 cm, and knock off the remaining relatively weak or diseased fruits. Only in this way can the pear tree maintain normal growth and provide sufficient nutrients to the fruit.
