Matters needing attention for citrus overwintering

Now it has entered late autumn, the weather is gradually getting cooler, of course, citrus is also the harvest season, for citrus growers, is a year of hard work harvest season. But it's also a season for growers to worry about, because autumn is coming, and next year's harvest may be affected if winter is mismanaged. Let's take a look at the four hazards that citrus overwintering needs to prevent.

1. Frost damage

The damage degree and location of citrus affected by frost are different due to the decrease of temperature and the duration of frost. the critical temperature of different varieties of citrus or different organs of the same kind of fruit trees is also different. In general, fruit growers will use smoking to prevent frost, which can reduce the loss of ground heat, but pay attention to safety during operation, and do not cause other harm to fruit trees because of smoking. Heaters can be used if possible, which can also effectively increase the temperature in the garden and prevent frost.

2. Freezing injury

The resistance of different growth organs of fruit trees to low temperature is different during the overwintering period. if the branches and buds are damaged by freezing, it is very likely to affect the yield of the following year, and in serious cases, it will cause the whole branch to die, which has a great impact on the production of fruit trees. There are also many causes of frost injury, which should be comprehensively prevented in production, such as light and late shearing, adequate moisture in the early stage, timely topdressing, maintaining nutrition and restoring tree potential as soon as possible.

3. Wind damage

The strong wind will also cause the partial crown or eccentricity of the fruit trees, and the strong wind will make the young trees dry and die in winter. the dry wind chamber pot in spring will lead to the scorching of the new tender leaves of the fruit trees, which will shorten the florescence, reduce the fruit setting rate and directly affect the yield. When there is a strong wind in the flowering period, artificial pollination can be used to increase the fruit setting rate. if it is windy in the production season, it is necessary to set up pillars to bind the fruit trees in time to prevent lodging and breaking branches, and when there is windy weather during the harvest period, they can turn over the tree plate or cover the tree plate with grass to reduce fruit drop.

4. Draw a strip

Striping occurs seriously in young Wo mandarin fruit trees, which often leads to tree type disorder and affects early fruit, but the way to prevent striping is to irrigate more fertilizer and water in the early stage of young tree growth, apply more phosphorus and potassium fertilizer in the later stage, and pick the heart scientifically and rationally. to promote the strong growth of branches and improve the overwintering of young trees.
