(3) The leaves are sprayed 4 to 5 times throughout the year, 2 times in the early stage of growth, mainly with nitrogen fertilizer; 2-3 times in the later stage, mainly with phosphorus and potash fertilizers. Commonly used fertilizers and concentrations: urea 0.3% -0.5%, potassium dihydrogen phosphate 0.3% -0.5%, borax 0.1% -0.3%. The last foliar spraying was carried out 20 days before the fruit harvesting period.
3. Pear (1) Base fertilizers are applied from late August to mid-September, mainly farmyard manure, plus a small amount of nitrogen fertilizer. Fertilizer amount is calculated according to the production of 1 kg of apples and 1.5-2 kg of high-quality farmyard manure. For producing 2,000 kilograms of fruit, 4,000 kilograms of high-quality manure should be applied; or 4,000 kilograms of legume green manure, and 50 kilograms of phosphorus fertilizer (P2O5, 12%) should be applied. , 50 kg of small gray or 16 kg of potassium sulfate.
(2) Dressing Fertilizer in the budding and flowering stage, flower bud differentiation period, and fruit rapid expansion period, apply 10-15 kilograms of urea per acre. The amount of fertilizer should be determined by the soil conditions and fertilization characteristics at that time. As a result, for every 100 kilograms of pear produced, trees should be topped with 0.94 kilograms of pure nitrogen, 0.77 kilograms of pure phosphorus (P2O5), and 1.20 kilograms of pure potassium (K2O). According to the orchard soil type, calcium, boron, zinc and other trace elements can be properly added.
(3) The foliar fertilizer is sprayed 4-5 times throughout the year. In the early stage of growth, nitrogen fertilizer is the main factor; in the later stage, it is 2-3 times, mainly by potash fertilizer. Commonly used fertilizers and concentrations: urea 0.3% -0.5%, potassium dihydrogen phosphate 0.2% -0.3%, borax 0.1% -0.3%. The last foliar spraying was carried out 20 days before the fruit harvesting period.
4. Peach (1) Base fertilizer is applied in autumn from mid-late August to early September, and is mainly farmyard manure with a small amount of nitrogen fertilizer. Fertilizer 1-3 years old saplings, apply 20-30 kg per plant. The result of the calculation is that the tree is used to produce 1 to 2 kg of high-quality farmyard manure per kilogram of peach, with an average yield of 2,000 to 3,000 kilograms of peach per mu and 4000 to 6,000 kilograms per mu.
(2) Dressing 1-3-year-old saplings, pre-emergence or post-emergence, topdressing 50-100 g of urea per 100-200 g of ammonium sulfate; 250-500 g of biological fertilizer applied to each shoot during the rapid growth of new shoots. . More than 4 years old, fruiting period is mainly in the early fruiting period; nitrogen fertilizer is the main part in the early fruiting period; 200-250 grams of urea and ammonium sulfate are added to each plant before or after flowering (ratio 3:7); hard core period, topdressing Bio-fertilizer 1-2 kg plus 200-250 grams of diammonium phosphate; fruit enlargement, topdressing bio-fertilizer 1-2 kg plus 500 grams of potassium sulfate. The harvest time of the last cropping interval must not be less than 30 days. The amount of fertilizer applied was based on the soil conditions, fertilization characteristics, and the results tree at the time. Generally, for each 100 kg of peaches produced, the amount of pure nitrogen 1.0 kg, pure phosphorus (P2O5) 0.7 kg, and pure potassium (K2O) 1.6 kg were calculated. In addition, according to the orchard soil type, calcium, boron, zinc and other trace elements can be properly added.
(3)Foliar spray fertilizer is applied 4-5 times in the whole year and 2 times in the early stage of growth. The main nitrogen fertilizer is used; 2-3 times in the later stage, mainly phosphorus and potash fertilizer. Commonly used fertilizers and concentrations: urea 0.3% -0.5%, potassium dihydrogen phosphate 0.2% -0.3%, borax 0.1% -0.3%. The last time was 20 days before the fruit harvesting period.
