When fertilizing the base fertilizer, it must be adapted to the distribution characteristics of the peach root system. The site of fertilization is on the outer edge of the vertical projection of the canopy to induce deep development of the root system. The density of the solar greenhouse is large, and it can be trenched between plants and rows. The ditch should be applied at a depth of 45-65 cm. The amount of fertilizer applied is 60% to 80% of the annual application.

The period and number of top dressing applications vary depending on the variety, soil quality, age, and tree potential. During the year of topdressing and fertilization, the types of fertilization are as follows:

The top dressing before flowering is mainly based on nitrogen fertilizer, and the amount of phosphorus fertilizer is combined to promote germination, and the flowering is neat, the fruit set rate is increased, and the growth of new shoots is increased.

In the hard core period, the top dressing should be carried out before the peach hard core, and the nitrogen-based compound fertilizer should be applied. Due to the development of seed nucleus during the hard core period, a large amount of nutrients are consumed. Timely topdressing can promote nuclear development and flower bud differentiation, which not only increases the yield of the year, but also plays an important role in the second year's yield.

The top dressing can be applied all year round, but it is suitable for the early stage of peach growth. The effect usually shows a certain reaction 10 to 15 days after application, but the effect disappears after 25 to 30 days. The top dressing is simple and easy to use. It has a small amount of fertilizer and plays a fast role. It can timely supplement the urgent need of nutrients in peach trees and avoid the chemical and biological fixation of phosphorus and potassium in the soil.

Foliar spray fertilizer spraying time is best before 10:00 am, after 4 pm, avoid spraying fertilizer at high temperature at noon to avoid fat damage. In order to save labor and time, it is also possible to spray together with the spray.
