What kind of fertilizer should be applied to peach trees in spring? With pruning techniques!

Spring is not only the season of peach blossom, but also the period of sprouting, blooming and fruit setting. The management of this stage is related to the yield and quality of peaches in the later stage. So, what kind of fertilizer should be applied to peach trees in spring? With pruning techniques!

What kind of fertilizer should be applied to peach trees in spring?

1. Fertilization time

Peach trees start the earliest growth activities in spring among fruit trees, and the supply of nutrients is earlier than that of other fruit trees. When the temperature rebounded after the Beginning of Spring, the nutritional demand of peach trees gradually increased, so it is necessary to apply pre-bud fertilizer. Generally applied 15 days before the Beginning of Spring, each peach tree applied 0.5kg of nitrogen, 0.3kg of potassium and 0.2kg of phosphorus, preferably mixed with mature human and animal feces, urine, water and fertilizer.

2. Fertilization formula

When fertilizing, a variety of nutrient element fertilizers should be applied. If the nutrient element of the fertilizer is single, the fruit quality will be poor and small, and there will be some deficiency diseases such as yellow leaves, leaflet fruit shrinkage disease and so on. It is suggested that when fertilizing, farm manure with fully matured nutrients should be given priority to.

3. Fertilization method

50% of phosphate and potassium fertilizers and 40% of nitrogen and organic fertilizers were applied on the basis, and the rest of nitrogen, phosphorus and potassium fertilizers were applied in stages according to the nutrient requirements of each growth stage. Generally, peach trees were applied for 3 times in sprouting stage (early March), hard core stage (mid-May) and fruit expansion stage. For the orchards with deciduous leaves in the early stage of the previous year, extra-root fertilization should be strengthened. 1%-3% urea solution could be sprayed 2 times before sprouting, and 2 times from sprouting to mid-July, with an interval of 7 days.

4. Pay attention to shallow application

Peach is a shallow-rooted tree species, and most of its roots are distributed at the depth of 20cm to 30cm. Therefore, peach tree fertilization should be appropriate shallow, fertilization depth of 30 cm is appropriate.

5. Fertilization location

The horizontal roots of peach trees are generally concentrated in the outer part of the crown, and the growth direction of the root system is often extended due to the position of fertilization, so fertilizer should be applied to the deeper and farther distribution of the root system, so as to induce the root system to develop in depth. expand growth surface and fertilizer absorption surface.

2. Pruning techniques of peach trees in spring

1. Twist the tip

It is twisted by hand in the semi-lignified part of the upright shoot, so that the xylem and phloem are sprained at the same time without breaking. The sprained shoots droop or flatten, generally about 30 cm in length, and twist the shoots 15 cm from the base. Twisting shoots can transform long branches into fruiting branches, improve light conditions, ease the tree potential, and prevent overgrowth.

2. Pick the heart

Is to remove the young part of the top of the growing branch, picking the core can change the distribution of nutrients. The temporary cessation of the growth of the coring branches is not only beneficial to the fullness of the branches and improve the plumpness of the flower buds, but also can reduce the nutritional competition with the adjacent branches and pick the coring when the shoot length is 20 cm. After picking the heart, the new tip is 30 cm long and then twisted.

3. Pull branches

Can open the angle, ease the tree potential, improve the lighting conditions, prevent the lower part of the branch bald, pull branches are generally carried out in May-June, when easy to pull shape, pull branch angle of about 80 degrees, can not be pulled into water.

In order to achieve high yield of peach trees, spring fertilization and pruning management are essential. In addition, due to different peach varieties, tree potential, climatic conditions, growth environment, cultivation and management measures, the specific management measures, fertilization methods and effects may be different, which should be adjusted according to the actual situation.
