Peach is delicious and nutritious. It is widely cultivated in most areas of China. Peach Xixi has a good light and good drainage, strong permeability, and soil fertility of sandy soil is better. The following principles should be paid attention to:
1 Fertilization should be combined with deep application and shallow application.
2 more organic fertilizer.
3 Saplings are dominated by phosphate fertilizers, combined with the application of nitrogen and potassium fertilizers, with particular attention to controlling the amount of nitrogen fertilizers. Nitrogen and potassium are the main components of adult trees, combined with the application of phosphate fertilizer and trace fertilizer.
4 Pay attention to timely monitoring of soil and tree nutrient content and timely adjust specific fertilization schemes.
The specific fertilization scheme is as follows:
1. Basal fertilizer: saplings: applied in the fall, soil excrement 20 to 50 kg/plant; superphosphate 0.2 to 0.5 kg/plant, urea 0.3 kg/plant, potassium sulfate 0.1 to 0.2 kg/plant, depending on the specific amount Soil nutrient determination results.
Adult tree: After the fruit is harvested, soil excrement 50 to 100 kg/plant; superphosphate 1.0 to 4.0 kg/plant; urea 0.3 to 1.5 kg/plant; potassium sulfate 0.5 to 1.5 kg/plant, pay attention not to close the fertilization time The tree is too close to avoid burning roots.
Second, top dressing: Generally 2 to 3 times a year fertilizer, saplings can not fertilize.
1 Promote flowering fertilizer: Apply it before flowering in early spring. Use nitrogen fertilizer as the main ingredient and apply 0.3-1.0 kg of ammonium bicarbonate per strain. According to the result of soil testing, add some potassium dihydrogen phosphate to some extent if necessary.
2 fruit setting period: the flowering period to the fruit before the nuclear hardening, to increase the fruit setting rate and promote the rapid growth of the fruit in the early period. Nitrogen fertilizer is mainly used, with a small amount of phosphorus and potassium fertilizer, 0.3-1.0 kg of ammonium bicarbonate per plant, 0.1-0.3 kg of potassium dihydrogen phosphate per strain, and 0-1.0 kg per strain of superphosphate.
Third, the application of trace element fertilizers:
The demand for trace elements in peach trees is small, mainly relying on organic fertilizers and soils. According to the results of soil testing, some of the scarce trace elements are sprayed on the surface of the trees and sprayed 2 to 3 times during vigorous growth.
