Peach tree fertilized in this way can increase sweetness and yield

When fertilizing the base fertilizer, it must be adapted to the distribution characteristics of the peach root system. The fertilization site was at the outer edge of the vertical projection of the canopy to induce deep root development. Sunlight greenhouses have a high density and can be ditched between plants and rows. It is advisable to ditch 45 to 65 cm deep. Fertilizer application rate is 60% ~ 80% of the annual application rate.

The application time and frequency of top dressing vary with species, soil quality, tree age, and tree vigor. The fertilization periods and types of fertilization during the year are as follows:

Fertilization before flowering is generally nitrogen-based, with an appropriate amount of phosphorus fertilizer to promote germination, make the flower tidy, increase fruit set rate, and increase the number of new shoots.

Topdressing in the hard core period This topdressing should be performed before the hard core of the peach, and topdressing with nitrogen-based compound fertilizer. Due to the development of the seed nucleus in the hard nucleus period, a large amount of nutrients are consumed, and timely fertilization can promote the development of the nucleus and the differentiation of flower buds, which not only improves the output of the current year, but also plays an important role in the output of the second year.

Topdressing outside the root can be applied throughout the year, but early peach growth is appropriate. The effect is usually seen within 10-15 days after application, but the effect disappears after 25-30 days. Topdressing outside the root is simple and easy, with a small amount of fertilizer, and it can play a fast role. It can timely replenish the urgent need of nutrients for peach trees, and can avoid the chemical and biological fixation of phosphorus and potassium in the soil.

Foliar spraying fertilizer The spraying time is best before 10 am and after 4 pm. Avoid spraying fertilizer at high temperature at noon to avoid fattening. In order to save labor and time, it can also be sprayed together with spraying.
