How to manage grapefruit in autumn

Pomelo in autumn is in the key period from autumn shoot growth to green ripening, fruit expansion and flower bud differentiation, autumn pomelo management directly affects fruit quality and yield in the coming year, so the management of pomelo in autumn can not be ignored. So how should autumn grapefruit be managed? Let's learn about it together with Xiaobian.

1. Reasonable fertilization

In order to ensure the quality and yield of grapefruit, fertilizer application in autumn should be from farm manure rich in phosphorus and potassium to heavy manure, and the amount of nitrogen fertilizer should be reduced as much as possible. When the orchard is short of phosphorus, it is necessary to increase phosphorus fertilizer appropriately, and when it is short of potassium, it is necessary to increase base fertilizer appropriately. Fertilization must be scientific and reasonable, and the amount, proportion and time of fertilization should be reasonably matched.

2. Reasonable irrigation

When the pomelo fruit continues to expand in autumn, the watering can provide water to the plant in time, so that the pulp cells divide and expand normally, which is beneficial to increasing the fruit volume and providing fruit quality. In addition, before grapefruit ripening, especially before harvest, water control should be appropriate, but water control should not be excessive, because too much drought will inhibit the normal physiological activities of the plant, so that the fruit acid drops slowly, resulting in greater fruit acidity.

3. Reasonable pruning

In autumn, we should increase the permeability of plants through reasonable pruning, change the light conditions of plants by thinning too dense weak branches, opening branch angle, changing branch extension direction, etc., so as to make fruits develop well and improve quality. In addition, flower and fruit thinning can also regulate fruit load, improve fruit size and endoplasm.

4. Timely harvest

Grapefruit can only realize its inherent quality characteristics after a specific growth and development process, so it cannot be harvested too early, which will affect the quality and yield of the fruit. However, it cannot be harvested too late, otherwise the storage is unfavorable, resulting in fruit quality in summer, so it is necessary to ensure the variety of grapefruit. It must be harvested at the right time.
