Pre-winter management of flower seedlings and prevention and control of edible fungus diseases

With the gradual decrease of air temperature, emphasis should be placed on the shaping and pruning of flowers and seedlings and the propagation of flowers and trees in autumn.

I. Reproduction

Sowing woody flowers are mainly peony, Michelia, magnolia, palm and so on; herbaceous flowers are hollyhock, petunia, Yu beauty, calendula, daisy and so on.

Cutting woody flowers are mainly rhododendron, camellia, red-backed cinnamon, five-colored plum, Michelia, Pueraria, red leaf Berberis, golden leaf privet, gardenia, rose, etc.; herbaceous flowers mainly have a string of red, cold water flowers, four seasons begonia, chrysanthemum and so on.

Continue to prune the hedges such as Ligustrum lucidum, Hongjimu and boxwood, and cut off the stump and abortive stems of flowering flowers such as rose and crape myrtle in time to promote their re-flowering.

VI. Pest control

If the garden is cleared in time, the dead branches and fallen leaves should be burned; the thick tree trunk can be whitened; 70% methyl Tobu body liquid or 50% carbendazim wettable powder 1000 times solution should be sprayed to control powdery mildew, brown spot and other diseases. Spraying 75% chlorothalonil wettable powder 800 times solution or 500 times solution of germicidal Dan for orchid anthracnose control. Spray 1000 times of dimethoate or 3000 times of deltamethrin to control bugs, whitefly, shell insects, red spiders and other pests. The methods of killing larvae and poisoning larvae can be used to control seedling hole pests.
