What compound fertilizer is usually applied to peach tree base fertilizer? When will it be used? What are the application techniques?

Base fertilizer refers to the fertilizer applied in combination with soil tillage before crop sowing or planting, perennial crops at the end of the growing season or the beginning of the growing season. What kind of compound fertilizer does peach tree base fertilizer apply? When will it be used? What are the application techniques?

What compound fertilizer does peach tree base fertilizer apply?

. When choosing fertilizers, many farmers only choose those that are cheap, only depending on the amount of fertilizer, regardless of the nutrient effective content of the fertilizer; applying unripe livestock fertilizer to the ground makes young trees easy to burn roots and die seedlings; if you choose fertilizers with high contents of nitrite and heavy metals, it will also cause serious pollution to the soil environment. So when choosing fertilizer:

1. Select fully mature farm manure

2. Livestock fertilizers must be decomposed, processed and decontaminated before they can be applied.

3. The peach orchard can be covered with grass or cereal straw in order to preserve fertilizer, preserve soil moisture, improve soil and enhance permeability.

When will the peach base fertilizer be applied?

1. It should be changed from late application to early application of base fertilizer. Early application of base fertilizer can make fertilizer integrate with soil as soon as possible, improve soil aggregate structure and improve soil fertilizer supply and water supply capacity.

2. It can cooperate with the second rooting peak of peach trees to promote multiple roots and deep roots; it can nurture flower buds, promote peach trees to blossom early, blossom more, bear more fruit early, appear on the market early and seize market opportunities, and significantly increase benefits. The base fertilizer for peach trees should be applied from early October to early November.

What are the application techniques of peach base fertilizer?

1. Depth: peach root system is relatively shallow, mostly distributed in the depth of 20-50 cm, therefore, the depth of fertilization is 30-40 cm.

2. Methods:

① ring ditch application is in the crown periphery, open a ring around the tree ditch, ditch depth of 30-40 cm, ditch width of 30-40 cm, the mixture of organic fertilizer and soil into the ditch, fill flat. This method is suitable for young trees.

② radiation ditch application is to open several radiation ditches from the side of the trunk to the periphery of the crown.

③ strip application is to open strip ditches on the east and west or north and south sides of the tree, but the position needs to be changed every year to balance the fertility.

④ is widely applied in the whole garden, the amount of fertilizer application is large and uniform, and ploughing after application should generally be 30 cm deep.

3. Change single fertilization to formula fertilization. According to the determination of agricultural scientific research department, the absorption ratio of nitrogen, phosphorus and potassium by peach trees is 1.00 ∶ 0.35 ∶ 1.45, and each element is indispensable, among which potassium is the most needed. Therefore, for the application of base fertilizer for adult peach trees, it is necessary to combine organic and inorganic fertilizers, a variety of nutrient elements, and varieties of different ripening stages. About 3000 kg of rotten farm manure or barnyard manure should be applied per mu, 200 kg of commercial organic fertilizer or 150 kg of bio-organic compound fertilizer should be applied per mu, and 0.6 kg of potassium sulfate compound fertilizer should be applied to each fruiting adult tree. This formula can not only increase the yield, but also improve the quality, increase the sugar content and brittleness obviously, and mature 3-5 days earlier. The content of nitrogen, phosphorus and potassium in the base fertilizer of early-maturing varieties should account for 70%-80% of the total amount of fertilizer applied in the whole year, while that of late-maturing varieties should account for 60%-70%. Those with higher soil fertility should be controlled to apply nitrogen fertilizer to prevent prosperous growth and shade, while those with low soil fertility can be increased appropriately.
