Detailed Explanation of Key Technical Points for Soil Testing and Formula Fertilization of Chestnut Trees
1. Main branch balancing (taking the three-main-branch open-center shape as an example). The main branches are the primary framework supporting all the branches. Before pruning, first carefully observe the orientation and growth vigor of the three main branches, have a clear picture in mind, and then make adjustments. For strong and vigorous main branches (with a large thickness ratio), strongly pull them to a wide angle, or use a side branch to replace the main branch extension head, combined with ring barking...

Detailed Explanation of Key Points for Fertilization and Water Management Techniques for Apricot Trees
I. Fertilization In the first year after planting, young trees are fertilized with light, frequent applications in order to rapidly expand the canopy and form a certain number of flower buds. The first fertilization is applied when the trees sprout after planting, after which a topdressing is applied once every 15-20 days, mainly with urea, combined with phosphorus and potassium fertilizers and organic fertilizer.

How to fertilize lychee? Master the nutrient requirements and fertilization techniques
(1) Nutrient requirements of lychee. According to measurements, in an orchard with a yield of 1000 kg per mu, every 1000 kg of mature fruit produced requires 9.8 kg of nitrogen, 1.1 kg of phosphorus, and 6.6 kg of potassium, with a nutrient ratio of 10:1:7. After fruit harvest and before ear emergence, generally two or three flushes of new shoots are produced before flower bud differentiation begins, and nitrogen demand is relatively high; from flower ear emergence to flower drop, the main processes are the growth and development of flower branches, flowers, and male and female flowers, and the proportion of phosphorus and potassium rises, but nitrogen still dominates; from pollination to fruit maturity, the main process is fruit growth and development, and the required ratio of nitrogen, phosphorus, and potassium is the same as in the previous stage.
