Winter management technology of pomelo

Grapefruit has a long understanding of cultivation in our country, and it is a common fruit in our life. Grapefruit is generally matured and listed in autumn and winter, and the management of this period is very important. It determines whether the plant can survive the winter safely, and is an important guarantee for the high and stable yield of grapefruit in the coming year, and the income of growers is closely related. So how to manage grapefruit in winter? Let's take a look.

1. Restore the tree potential

After the grapefruit blossoms and bears fruit, the growth of the fruit will consume a lot of nutrients of the plant, and so on, it will often cause the weakness of the tree and the yellowing and shedding of leaves. Therefore, it is necessary to restore the tree potential in time after fruit harvest, otherwise it will affect the treatment of flower buds in the coming year, resulting in a decline in yield and affecting income. After fruit picking, fruit fertilizer should be applied in time to supplement nutrition to promote the recovery of plant potential as soon as possible. Fruit picking fertilizer is mainly quick-acting compound fertilizer, so that it can be absorbed by roots as soon as possible and provide nutrients for plants.

2. Promote flower bud differentiation.

Because of the lack of nutrition after fruit picking, it often leads to the phenomenon of poor flower bud differentiation, so measures should be taken to promote flower bud differentiation, generally there are two methods: physical regulation and chemical regulation. The physical control methods are mainly to peel the plant around, wipe the winter buds, prune, cut roots and control water, so that it can inhibit the growth of new shoots, help branches and leaves to accumulate more nutrients, and improve flower bud formation and fruit setting rate in the coming year. Chemical regulation is to spray plant regulators to control plant hormone balance and promote plant flower bud differentiation.

3. Apply overwintering fertilizer

In order to make the plant survive the winter safely, the overwintering fertilizer was applied in combination with deep turning soil before freezing. The overwintering fertilizer was mainly organic fertilizer, mixed with phosphorus, potassium fertilizer and other trace elements. Generally speaking, the adult fruiting plant should apply 10-15 jin of organic fertilizer per plant, and it can also be applied according to the size of the plant, the number of fruit and the increase or decrease of growth.

4. Clear the garden

Clearing the garden in winter is also a key point in winter management. after a year, a large number of dead branches and residual leaves have been produced on the ground in the pomelo orchard, and many sources of diseases and insect pests generally survive the winter in these withered branches and leaves, and continue to harm plants in the coming year. Therefore, the garden should be cleaned in all aspects in winter, and the dead branches and leaves on the ground should be burned or buried deeply, so as to reduce the source of overwintering diseases and insect pests. In addition, some diseased branches and leaves of the plant should be disposed of together, and then the garden and the plant should be sprayed to eliminate the source of overwintering diseases and insect pests again.
