Peach had more potassium uptake than nitrogen and more phosphorus than the total nitrogen, phosphorus, and potassium in the whole tree within a year of 10:4:13. The amount of fertilizer applied to adult peaches is 50 kg per fruit, 100-150 kg of basal fertilizer and 0.35-0.40 kg of effective nitrogen, 0.2-5.30 kg of phosphorus, and 0.5 kg of potassium. The application of organic fertilizer production in the fall and spring seasons. At present, autumn fertilization is advocated in early autumn, from late August to early September. The amount of fertilizer used in the early autumn is two-thirds of the total amount of fertilizer used in the whole year, and the remaining one-third of the following spring.
Grapes usually use manure, chicken manure, cake fertilizer, grass ash and other good farmyard manure. For each 100 kg of fruit produced, 319 grams of nitrogen, 231 grams of phosphorus, and 526 grams of potassium are required. If you plan to produce 200 kilograms of fruit per plant, you should apply 80 grams of nitrogen (300 grams of urea), 50 grams of phosphorus (that is, 1000 grams of calcium phosphate), and 110 grams of potassium (400 grams of potassium sulfate). Fertilization in early fall usually begins one week after harvest.
The amount of fertilizer applied to apples varies depending on the species, tree vigor, age, amount of results, and soil fertility. During the sapling period, the apple tree needs less fertilizer, and the general plant applies 15-20 kilograms of human excreta, 0.5 kilograms of ammonium sulfate, and about 0.25 kilograms of pure nitrogen. In the result period, generally, 1.2-1.5 kg of nitrogen, 0.4-0.8 kg of phosphorus, and 0.6-1.0 kg of potassium should be applied for every 100 kg of fruit produced. It is advisable to fertilize early fall.

Pear production promotes early autumn base fertilizer. Generally speaking, the young pear trees need less, and the pear trees entering the production period generally have 50 kg of fine manure, 50 kg of ammonium sulfate, 0.5-1.5 kg of superphosphate, and 2-2.5 kg of plant ash. Basal fertilizers are generally applied in autumn, winter, and spring, and are best applied in autumn. Top dressings are usually carried out before, after, and during fruit enlargement.
