Remember these high-yield fertilization points for peaches to "bend over" your fruit trees!

Every year from June to August is the time for juicy and delicious peaches to be fresh on the market, and it is also the happiest time for fruit farmers. In the case of a good market, the higher the yield, the better. Let's talk about the key points of high-yield fertilization for peaches. Do a good job in these points to make your fruit trees "bend over"!

First, how to fertilize peaches?

1. Peaches apply strong fruit fertilizer in summer, spread a piece of land, and then plough a piece of land, the depth is about lO centimeters, do not be afraid that the root will affect the tree potential. Summer can also be used in rainy days without ploughing. The application of base fertilizer from August to October in postharvest autumn can be ploughed in the whole garden after ditch application, hole application or spread application. In case of autumn drought, it is best to apply it immediately after raining. If fertilizing in a relatively dry period, there will be too many roots and a large number of fallen leaves.

two。 The basic fertilizer of peach is recommended to be applied in winter and autumn, mainly organic fertilizer, accounting for 60%-70% of the total amount of fertilizer applied in the whole year, generally applying base fertilizer 2000kg per mu or special fertilizer for fruit trees per mu. The times, time and amount of topdressing vary according to varieties, tree ages, cultivation and management methods, growth and development periods and external conditions, generally giving priority to pre-bud fertilizer, strong fruit fertilizer and postharvest fertilizer. In addition, extra-root topdressing is a necessary supplement to soil fertilization. because peach trees are sensitive to trace elements and are prone to temporary relative deficiency, 0.2% boric acid aqueous solution is sprayed at the early flowering stage, according to different varieties from late May to early September. 0.4% potassium dihydrogen phosphate was sprayed twice, and 0.2% potassium dihydrogen phosphate was sprayed at the middle stage of fruit growth.

What kind of fertilizer should be used for peaches?

1. Fat before budding. It is generally applied in the first 15 days of the Beginning of Spring, which can not only make up for the lack of fertilization or non-fertilization after fruit, but also supplement the lack of nutrients in peach trees in time. Generally, each peach tree is treated with urea 0.5kg, potassium chloride 0.3kg and calcium superphosphate 0.2kg, which can be mixed with mature human feces and urine for rhizosphere topdressing.

two。 Fat before flowering. Applied 15-20 days before flowering, mainly nitrogen fertilizer, each plant can be applied 0.5~1kg urea, boron fertilizer 0.25kg, pay attention to be mixed with farm manure.

3. Peach kernel fertilizer. When the peach stone is formed, the amount of fertilizer needs to increase, so the fertilizer should be supplemented in time, mainly with total potassium fertilizer, supplemented by nitrogen and phosphorus fertilizer, and mixed application of nitrogen, phosphorus and potassium fertilizer combined with farm manure. Generally, each peach tree is treated with potassium chloride 0.3~0.5kg.

4. Fruit-picking fertilizer. 1.5 to 20 days before fruit harvest, the fruit expansion rate was accelerated, and the application of potassium fertilizer could effectively improve the yield and quality of peach. After fruit harvesting, nitrogen and phosphorus were the main fertilizers, and urea 1.5~2kg and calcium superphosphate 1~1.5kg were applied per 50kg fruit to promote root development and enhance overwintering ability.

5. Foliar fertilizer. Peach trees can apply foliar fertilizer within 20 days from foliage expansion to defoliation, and foliar fertilizer can also be applied in combination with disease prevention and pest control, and boron, zinc, manganese and potassium fertilizer should be used. It should be sprayed on a sunny day, and the types of fertilizers are 0.1%-0.25% boric acid, 0.1% zinc sulfate, 0.25%-0.3% manganese chloride, 0.3% potassium dihydrogen sulfate, 0.2% ferrous sulfate, and the barren land can be properly increased.

Third, how to shape and prune peaches?

In order to have a high yield of peaches, it is necessary to do a good job of shaping and pruning in addition to fertilization:

Reasonable shaping peach trees like light, plastic to ventilation and light transmission as the goal, to cultivate a natural happy crown. After the planting survived, the stem was fixed at 60-80 points off the ground, leaving 3-4 branches as the main branches after sprouting, and pay attention to controlling the branch angle of about 60 degrees and the spacing of 10mr. When the main branch grows to 50-60cm, the 40cm is left and right truncated, and the cutting bud remains extroverted, allowing it to continue to extend outward. After truncation, 2-3 long branches were drawn from the top as secondary main branches. when the main branches were extended to 50-602, they were then cut short, and the upward long branches and overgrown branches were cut off from the base. The pruning of young trees is also different from that of adult trees.

(1) pruning young trees. In summer, it is mainly to pick the heart and remove unreasonable overgrown branches. It is mainly short in winter. According to the characteristic that the young trees bear fruit mainly with long fruit branches, the long fruit branches should be retained as far as possible, and 6-8 flower buds should be cut short. The middle fruit branches in the middle and lower part of the crown should be kept at a distance of about 10cm, and if they are too dense, they should be thinned in time. The well-positioned developmental branches were reserved as auxiliary branches and were cultured as fruiting branches after proper short pruning.

(2) pruning adult trees. In summer, the erect long branches and over-dense branches are mainly removed from the secondary main branches. In winter, sulfur removal and truncation were carried out according to the tree potential, and combined with pruning and adjusting the yield. Properly remove and cut the long fruit branches in the upper and outer parts of the crown, retain the medium and short fruit branches, and trim the fruiting branches outside the crown by trimming three long branches, two long branches and one double cut, so as to form a concave and convex shape on the outside of the crown. to make better use of light energy. This can increase light transmission, reduce the harm of diseases and insect pests, promote three-dimensional fruit, improve fruit chromaticity, improve fruit quality, at the same time, fruit branches can bear fruit alternately, overcome big and small years, and maintain high yield and stability.
