Post-harvest management of grapefruit trees

After picking the grapefruit tree, it is necessary to prepare for next year's bumper harvest, so the management after picking is very important. Grapefruit tree late management needs to pay attention to fertilizer and orchard management this part, to let it through a nutritious and healthy winter, growers still need to make a lot of efforts, the following editor and you will introduce a few points in detail.

1. Topdressing

The pomelo tree has just finished its fruit hanging period, and its nutrition consumption is very large. Generally, grapefruit trees will not be fertilized a month before picking. At this time, grapefruit trees are in great need of supplementary nutrients. Sufficient nutrients can make it better to resist the low temperature in winter and keep it energetic, so what should be fertilized? The editor advises growers to fill farm manure around their roots. This kind of fertilizer has a full range of trace elements, which is most suitable for replenishing the nutrients needed by grapefruit trees at this time. 20 centimeters away from its trunk, it is round and surrounded by manure. Then bury it with soil.

2. Orchard cleaning

Many pest sources of pomelo trees will be attached to the branches and leaves, waiting for the chance of rebirth in the coming year, and some of the residual branches and leaves during picking are very likely to carry the source, so it is important to clean up the residual branches of the orchard. If these residual branches are not cleaned up, the source of diseases and insect pests will slowly absorb nutrients with the decay of the residues, and finally enter the soil, so that they can avoid the low temperature season and bury the hidden dangers of later disease. Farmers should pay attention to this aspect.

3. Pruning branches

The thicker the fruit trees are, the better. Too dense will reduce the fruit rate and rob them of nutrients. It is necessary to clean up some branches after picking. When pruning, we should pay attention to the dense areas with few results and focus on cleaning, so as not to reduce the output. As a result, the upper branches and leaves of the spot can not make its Mandarin dense, thus making it difficult for the fruit to enjoy the sun and reduce the quality. The growth direction is scattered, and those who do not focus on upward growth need to be cleaned up, which will affect the growth of fruit trees. these are three points to pay attention to.

4. Heat preservation measures

Grapefruit tree picking is basically accompanied by the arrival of winter, so heat preservation is extremely necessary, otherwise fruit trees frostbite, frostbite to death will cause unnecessary losses. Root heat preservation can be carried out by cultivating soil, that is, the soil at the root is piled high, which has achieved the effect of heat preservation. If the temperature is below zero, or if there is a freezing disaster, you can add insulation film to the grapefruit tree so that it can survive the winter.

The management of grapefruit after harvest is very important, and this is the first-hand guarantee of high yield in the coming year. The bumper harvest of that year only means that we have done well before, and we should also pay attention to the bumper harvest later.
