Sunscreen and fruit protection of growing pineapple and management of cold protection in winter

(1) sunscreen fruit protection

The development period of the positive fruit with the crown bud removed is in the middle of summer, and it is easy to be burned by the hot sun, which affects the fruit quality. Therefore, we must do a good job of sunscreen and fruit protection. Generally, one month before the fruit harvest, cover the top with pine hair, awn dustpan, mountain grass and so on. Then tie the two opposite leaves to prevent the mulch from being blown away by the wind. Cain-free species can also use several bundles of their own leaves to cover the fruit, but not too tight or too dense, so as not to affect the fruit development.

(2) Prevention of cold in winter

Pineapple is vulnerable to cold damage during low temperatures in winter, especially when frost and cold rain enter the growing point, often causing heartache or death. Therefore, attention should be paid to cold prevention in areas vulnerable to cold damage. Bundles are generally used to prevent frost, that is, the leaves of the plant are tied up before the cold winter to protect the heart leaves and several internal leaves from damage. There are also those that cover the top of the plant with straw, weeds or hard paper to protect the growth point, and the effect is best if it can be covered with white plastic film.

If the plant suffers frost, the garden should be cleared after the spring is warm, the damaged dry leaves should be cut off in time, and the soil should be fertilized in time to promote the emergence of new leaves, and the dead seedlings should be dug up and replanted or replanted as soon as possible. The small fruits that cannot grow should be removed as soon as possible to make the new buds grow stronger.
