How to manage papaya trees in winter

Papaya is a typical tropical plant, so papaya needs a higher temperature in its growth. The ability to bear the low temperature is not strong, but after entering the winter, it is very easy to be affected because of the low temperature and many frosts. Therefore, we should pay attention to the management work in winter, so how to manage the papaya tree in winter? The following editor will give you a brief introduction, let's have a look!

Usually in late September, the soil of the papaya orchard is turned deep and combined with base fertilizer. The base fertilizer is mainly stable fertilizer and farm manure, combined with an appropriate amount of available chemical fertilizer and so on. Control the application amount according to the tree age, if it is a young tree, then each tree should be applied about 20-25kg, if it is an adult tree, then it should be applied about 40kg.

2. Control the autumn shoot

In autumn, the growth of new shoots will enter the peak period, thus forming autumn shoots. If the autumn shoot grows vigorously, it will lead to excessive nutrient consumption of papaya trees, decline of tree potential, and affect the dormancy of papaya trees. So from October to November, ring cutting should be carried out in the smooth trunk of the papaya tree, cut to the xylem, and then smear the ring cutting area with chemicals such as the king of flowers. If the growth is prosperous, then it should be used once a month or so, and if the tree is weak, it can be used once a month. Proper application of flower promotion to control autumn shoots can improve the dormancy quality of papaya trees, avoid the phenomenon of big and small years, and ensure that papaya trees survive the winter safely.

Then the trunk is also whitened with whitening agent, which plays the role of anti-freezing and heat preservation. Finally, the eggs in the bark and crevices should be carefully examined and eliminated, so as to eliminate the source of disease and insect infection to the greatest extent.

Do not prune too late, otherwise it is easy to appear lobular phenomenon, in pruning, the trunk is too thick of the main branch, about two, from the bottom up, improve the crown permeability. Then it is necessary to timely remove competitive branches, overgrown branches and some fruiting branches that will affect the potential of papaya trees. Then the branches such as whorled branches and overlapping branches should be properly adjusted every year according to the principle of thinning strong and large first. Finally, thinning, retraction, branch pulling and other methods should be used for pruning. The wound should be treated after pruning to avoid cracking and being harmed by germs.
