The latest course on fertilization techniques of Sweet Cherry

Sweet cherry is one of the early mature species in deciduous fruit trees, but the traditional cultivation of sweet cherry has late fruit, low yield and poor benefit. according to the practice, mastering scientific and reasonable fertilization technology can make the early high yield of sweet cherry become a reality. So how to fertilize sweet cherries? Come and have a look with the editor.

First, the characteristics of fertilizer demand

The fertilization of sweet cherry should be based on tree potential, tree age, soil fertility and fertilizer demand characteristics of varieties, grasp the time, method and amount of fertilizer application, and supply various reasons for the growth and development of sweet cherry in time, so as to achieve the purpose of strong tree, high quality and high yield. The young trees of less than 3 years are in the crown expansion period, when the demand for nitrogen and phosphorus fertilizer is greater, with nitrogen fertilizer Uygur, supplemented with an appropriate amount of phosphate fertilizer to promote the early formation of the crown. For the fruiting trees of 4-6 years, in addition to crown expansion and branch and leaf growth, it is still in the process of transformation from vegetative growth to reproductive growth, so you are the key to promote flower bud differentiation. At this time, we should control the amount of nitrogen fertilizer and increase the application of phosphorus and potassium fertilizer. In the fruiting trees of 7 years, there is more demand for potash fertilizer for fruit growth and development, so the application rate of love fee should be increased.

II. Principles of fertilization

Sweet cherry fertilization is mainly organic fertilizer, which not only has comprehensive nutrients, but also can improve the soil structure, which is beneficial to the root growth and expand the root range of sweet cherry. Early basal fertilizer and more application of organic fertilizer can increase plant vegetative storage, increase fruit setting rate, increase yield and improve quality. In the key fertilization period in the growth period, the growth period should be promoted first, and then the crown should be controlled in time to promote flower bud differentiation.

III. Fertilization technology

Autumn fertilization base fertilizer is mainly organic fertilizer, generally in September-October chicken heart, early application is better, so as to give play to the effect of fertilizer as soon as possible, conducive to tree nutrition storage, the main methods of base fertilizer application are radiation ditch and annular ditch method. In the cherry blooming and fruiting period, it will consume a lot of nutrients, so it is proud of the nutrition requirements, so it is necessary to apply timely and sufficient amount of quick-acting fertilizer to improve the fruit setting rate and increase the weight of single fruit. At this time, nitrogen, phosphorus and potassium compound fertilizer is the main fertilizer, and about 1 kg of compound fertilizer is applied to each fruit tree. In addition, borax can be sprayed 1-2 times in the flowering stage, and potassium dihydrogen phosphate can be sprayed 2-3 times in the coloring period, which is suitable for next afternoon or evening.

The above is the introduction of sweet cherry fertilization technology, hope to help you, want to know more related knowledge, please follow us.
