In the key link of peach growth, if the fertilization period is mastered, the proper proportion of nitrogen, phosphorus and potassium fertilizers should be maintained to prevent nutrient deficiency, so that the growth and results of peach trees can be balanced, the growth is good, and the effect of stable yield and high yield can be obtained. Therefore, the peach trees should be applied five times in the whole year.
Applying the pre-emergence fertilizer The temperature rises after the spring, and when the temperature is reached, the microbial and peach root activities in the soil are accelerated, and the demand for nutrients is gradually increasing. Therefore, the pre-emergence fertilizer should be applied 15 days before the beginning of spring, which can not only compensate for the problem of insufficient or no fertilization after fruiting. It can also timely supplement the deficiency of nutrients in the peach tree. Each peach is applied with 0.5 kg of nitrogen, 0.3 kg of potassium, and 0.2 kg of phosphorus, and is mixed with manure and manure and then applied as root dressing.
Applying enough flowers before flowering Peach trees need sufficient nutrients to ensure that the roots are developed, the branches and leaves are flourishing, and the young trees, young fruits and new shoots grow normally, so that the old trees glow with "young" branches and grow quickly and grow healthily. The fertilization should be carried out 15-20 before flowering, mainly nitrogen fertilizer, 0.5-1 kg of nitrogen fertilizer per plant, and 0.25 kg of boron fertilizer. Be sure to mix farmyard manure.
When the peach nucleus is formed, the seed embryo grows faster, and the nutrient absorption of the fruit gradually increases. At this time, the peach tree is flourishing and requires a large amount of fertilizer. This time should be based on total potassium fertilizer, supplemented by nitrogen and phosphorus fertilizers, the implementation of NPK combined with farmyard manure, the effect is very good, each plant applied 0.3-0.5 kg of potassium chloride.
Applying fruit before and after harvesting for 15-20 days before fruit harvesting, the fruit expansion speed is accelerated. Potassium fertilizer can effectively increase peach yield and fruit quality, and about 0.15 kg of potassium fertilizer per 50 kg of fruit. After picking the fruit, the peach tree has completed a production process and consumes a lot of nutrients. At this time, nitrogen and phosphate fertilizers should be mainly used. About 1.5-2 kg of nitrogen and 1.5-1.5 kg of phosphate fertilizer should be applied for each 50 kg of fruit to promote the development of root system. The tree body has sufficient nutrition, the leaves and leaves are enriched, and the ability to overwinter is enhanced.
Applying foliar-faced fat peach trees from the leaves after the leaves until 20 days before the leaves, the leaves can be applied to the fertilizer for a long time, and the fertilizers can be applied to the fertilizers, and the effects can be improved. External application of fertilizer, application of boron, zinc, manganese, potassium fertilizer effect is good, sprayed on sunny days, the amount of boric acid 0.1-0.25%, zinc sulfate 0.1%, manganese chloride 0.25-0.3%, potassium dihydrogen sulfate 0.3- 0.5%, ferrous sulfate 0.2-1%, the soil is thin and appropriate to increase the application.
