Sun protection, fruit protection and winter cold protection management methods for pineapple cultivation

(1) Sun protection and fruit protection

The development period of the main crop after the crown buds have been removed coincides with midsummer, and the fruit is easily sunburned by direct sunlight, affecting fruit quality. Therefore, sun protection and fruit protection work must be done well. Generally, 1 month before fruit harvest, cover the top with pine needles, fern, mountain grass, etc. Then tie together two opposite leaves to prevent the covering material from being blown away by the wind. For the Cayenne variety, several of its own leaves can also be gathered and tied to cover the fruit, but they must not be tied too tightly or too densely, so as not to affect fruit development.

(2) Winter cold protection

Pineapples are susceptible to cold damage during periods of low temperature in winter, especially when frost and cold rain seep into the growing point, often causing heart rot or death. Therefore, in areas prone to cold damage, attention should be paid to doing good cold protection work. Generally, leaf binding is used to protect against frost, that is, before the cold winter arrives, the leaves of the plant are tied up to protect the heart leaves and the several inner leaves from damage. Some also use rice straw, weeds or cardboard to cover the top of the plant to protect the growing point; if white plastic film can be used to cover it, the effect is best.

If the plants suffer frost damage, clear the garden after the weather warms in spring, cut off the damaged dry leaves in time, and apply fertilizer and earth up in time to promote the emergence of new leaves. Dead seedlings should be dug up and replanted as soon as possible, or the field should be plowed and replanted. Small fruits that cannot grow should be removed early so that new shoots can emerge and grow strong.
