How to prevent Myrica rubra from freezing in extremely cold weather

When Myrica rubra meets extremely cold weather, it can be covered with greenhouses and plastic films to prevent freezing, which can warm Myrica rubra, make it grow better and spend the extremely cold weather better.

growing environment

Yangmeixi acid soil is native to the hillside or valley forest at an altitude of 125- 1500m in temperate and subtropical humid climate zones in China. Mainly distributed in the south of the Yangtze River valley and the north of Hainan Island, that is, between 20 degrees north latitude and 3 1 degree, it is similar to citrus, loquat, tea tree and Phyllostachys pubescens, but has stronger cold resistance than citrus and loquat.

Greenhouse was originally a special equipment for vegetable production, and it has been widely used with the development of production. At present, the greenhouse has been used to cultivate potted flowers and cut flowers; Fruit tree production is used to grow grapes, strawberries, watermelons, melons, peaches and oranges; Forestry production is used to raise seedlings and cultivate ornamental trees. Aquaculture is used to raise silkworms, chickens, cattle, pigs, fish and fry.

cultivation type

Seedling type:

It is characterized by seedling raising in winter → early maturity cultivation in spring → seedling raising in summer → autumn and winter cultivation. In winter, seedlings are usually raised from June 1 1 to the middle and late March of the following year, and seedlings of solanaceous fruits, melons and beans are cultivated. Sow in the middle and late March and cultivate early in spring. Raise seedlings in summer from June to August, such as cabbage, cauliflower and tomato. Plant autumn tomatoes, cucumbers, leafy vegetables, celery, onions and garlic in autumn and winter.

Cultivation type:

Mainly cultivated vegetables, combined with seedling raising. There are two main forms: one is to plant eggplant, tomato, cucumber and pepper in early spring, fast-growing vegetables in summer, cucumber, tomato, cabbage and cauliflower in autumn, celery, spinach, lettuce and onion and garlic in winter; The second is intercropping, in which tomatoes and peppers are planted in early spring, and loofah is planted next to the arch pole in the greenhouse in April-May, so that it can climb along the arch pole, or in the later stage of tomato growth, wax gourd is planted in the border, and vines are climbed by tomato brackets; Planting lettuce and cabbage in autumn; Seedling raising is carried out in winter.

Seed reserves and seed production types:

There are mainly two ways: one is to leave eggplant and melon seeds in spring, and the stubble-leaving way is to raise seedlings in winter → leave seeds in spring → cultivate celery and cabbage in autumn; One is to collect and reserve seeds mainly from Cruciferae self-incompatibility in winter and spring, raise seedlings in summer and cultivate eggplant and melon vegetables in autumn.

When Myrica rubra meets extremely cold weather, it can be covered with greenhouses and plastic films to prevent freezing, which can warm Myrica rubra, make it grow better and spend the extremely cold weather better. Therefore, when Myrica rubra encounters extremely cold weather, a greenhouse can be built and covered with plastic film to make Myrica rubra spend the extremely cold weather.
