How to pollinate plum trees artificially

Pollen needs to be collected for artificial pollination of plum trees, and the pollination time is completed within 2~3 days at the initial flowering stage. Generally, the pollination effect is the best on the day of flowering. The suitable signs of flower pollination are that the stamen anther is still partially unbroken, the pistil style is fresh and the stigma mucus is secreted.

When plum trees are in full bloom, gently roll with a feather duster or towel stick between the flowers of the main varieties and pollinated varieties; Or the collected pollen and talcum powder are mixed according to the ratio of 1: 1, put into a cloth bag, and shake and pollinate on the blooming main varieties; You can also put the flower branches in water bottles and hang them on the trees of the main varieties.

Spraying plant growth regulators and nutrient elements

Plant growth regulator PBO is usually sprayed with 150 times solution when plum blossoms just bloom; Or spraying 0.3%~0.5% borax and adding 100 times of sugar or brown sugar at the full flowering stage of plums can improve the fruit setting rate.

Flowering ring cutting

In the early flowering period of plum trees, cutting the trunk around for three times, with a distance of 65438±0.5cm, directly to the xylem, can obviously improve the fruit setting rate of plum trees.
