The Best Pollinating Time for Pear Trees

Pear tree has been cultivated in China for at least 3000 years, and its yield is second only to apple. In order to increase the yield, artificial pollination is now more used. when is the best time for pollination of pear trees? How many years of planting can you hang fruit?

The best time for pollination of pear trees

The best time for pollination of pear trees is within 5-7 days after pear blossoms, and it is appropriate to complete artificial pollination within 3 days. Pear trees can be pollinated from 8: 00 in the morning to 4: 00 in the afternoon. If the temperature during the pollination period is less than 10 degrees, choose to carry out artificial pollination in the morning or evening if the temperature rises above 12 degrees in the afternoon and above 30 degrees.

Second, how many years can pear trees hang fruit after planting?

In general, it takes about five years for newly planted pear trees to bear fruit, while some varieties may take a short time, as long as four years. Basically, pear trees enter the full fruit period after planting for 6-7 years. If properly managed, the yield per mu of pear trees in the full fruit period is 5000-6000 jin, and the high yield can reach about 8000 jin.

In addition, there are several situations that will cause pear trees to blossom but not bear fruit, one is the partial application of nitrogen fertilizer. The partial application of nitrogen fertilizer will cause the trees to grow luxuriantly, with only branches and no fruit. In addition, some fruit growers apply unripe farm manure into the orchard, causing pear trees to grow tall, but only blossom but not bear fruit; second, poor drainage, pear trees bloom generally Rain Water too much, orchard stagnant water will frustrate tree growth, thus hanging less fruit; third, there is a lack of pollination trees. Pear trees belong to cross-pollination plants, and the fruit setting rate of pollination within varieties is low.

As the main economic cultivation in China, pear trees include Qiuzi pear, white pear, sand pear, Yangli pear and Xinjiang pear. Growers should determine the specific varieties to be planted according to the market and planting environment at that time.
