How can growing grapefruit bear fruit

If the pomelo tree only blossoms but does not bear fruit, the ring cutting method can be adopted when the fruit tree blossoms to concentrate nutrients on the flowers and fruits, promote fruit, and carry out artificial pollination to improve the fruit rate and fruit quality of fruit trees. If the grapefruit tree does not bloom and does not bear fruit, the weak branches of the fruit tree mulberry that consume nutrients can be cut off, checked for diseases and fertilized by loosening the soil.

Generally, grapefruit trees will begin to bear fruit in 8-10 years, grafted grapefruit trees will bear fruit in 4-5 years, and will enter the full fruit stage 1-2 years after the first fruit. The yield of 5-7-year-old grafted trees can reach 15-50kg/ trees, and the yield of 8-10-year-old grafted trees can reach 50-100kg/ trees.

The grapefruit tree does not blossom

If the planted grapefruit tree does not blossom, then it is necessary to prune and pull the fruit tree, remove the weak branches that consume nutrition on the fruit tree, check the fruit tree for insect pests, and finally loosen the soil for fertilization. it is best not to apply fertilizer only under the grapefruit tree. Fertilizers should be applied within several square meters around the planted fruit trees to ensure adequate nutrients.

The grapefruit tree only blossoms but does not bear fruit.

The pomelo tree blossoms a lot but does not bear fruit. When it blossoms, the pomelo tree is ring-cut, and then pollinated artificially, so that the grapefruit tree will hang up its fruit.

1. Ring cutting: use a knife to cut one or two circles on the bark of the trunk of the fruit tree, so that nutrients are concentrated on the flowers and fruits of the fruit tree. In the ring cutting, we should pay attention to the incision is not too deep, so as not to damage the xylem, the general fruit trees can heal in about 10 days.

2. Artificial pollination: the fruit rate of grapefruit trees pollinated by different plants will be higher, and the fruit sweetness will also be higher. Although grapefruit trees pollinated by self-pollination can bear fruit, the fruit rate is relatively low, and the fruit taste is not good. So now growers will choose artificial pollination to improve the fruit rate and fruit quality of fruit trees.

The method of fertilization for planting grapefruit

1. Fruit protection fertilizer

The pomelo tree has a relatively large output in spring, and it needs to consume a lot of nutrients when it blossoms. Generally, if the young fruit is formed in May-June, the phenomenon of fruit drop will occur if the nutrients are insufficient. When the trees with a large number of blossoms or old trees are physiologically falling fruit for the first time, it is necessary to apply a quick-acting fruit-protecting compound fertilizer to the grapefruit tree, at the same time, it is used with mature farm fertilizer to stabilize the fruit.

When topdressing, it is best to choose potash fertilizer, phosphate fertilizer, but also with a certain amount of nitrogen fertilizer and magnesium fertilizer, the amount of topdressing of grapefruit trees is more, and pomelo trees can be applied less or not, so as to avoid causing fruit trees to draw a little too much and increase the amount of fruit fall. the amount of topdressing should account for 5-10% of the total amount of fertilizer applied in the whole year.

2. Strong fruit to promote a little fat

When the physiological fruit drop period of grapefruit is over, the fruit will expand rapidly, and the ability of the root to absorb nutrients will be enhanced. At this time, it will be released slightly in early autumn, so make sure that the nutrients are adequate.

Applying ripened organic fertilizer to fruit trees in mid-early July to make the fruit expand and enrich slightly in early autumn, preparing a sufficient nutritional basis for flower bud differentiation, the amount of topdressing should account for about 30% of the total fertilizer applied in the whole year.

3. Fruit picking fertilizer

Fertilizer can be applied 7-10 days before picking, or after picking, in order to promote the recovery of tree potential, retain the leaves on the tree to survive the winter, promote flower bud differentiation and reduce annual fruit.

The main application of organic fertilizer, combined with calcium phosphate, calcium sulfate and bone powder together, fertilization should pay attention to re-application, early application, if it is an early-maturing variety, it should be fertilized in time after picking the fruit, and if the late-maturing variety, it should be fertilized before picking the fruit. The older grapefruit trees should be fertilized timely and many times, while the younger grapefruit trees can apply less fertilizer and inhibit the formation of flower buds too much. The amount of fertilizer should account for 40-45% of the total amount of fertilizer applied in the whole year.
