Methods and Technical Key Points for Summer Topdressing of Fruit Trees
How to do summer topdressing for fruit trees? Please introduce the methods. In mid-to-late June, the fruits of grape, pear and other fruit trees begin to swell and are in the first rapid expansion stage. Flower buds are in the physiological differentiation stage, their root systems grow rapidly and their absorption function is active, making nutrient deficiency likely. During this critical period, timely and appropriate topdressing can supplement the nutrients needed by the tree and promote...

Methods and Technical Key Points for Applying Potassium Fertilizer in Orchards
How should potassium fertilizer be applied in orchards? What methods are there? Traditional orchard fertilization methods often focus only on applying nitrogen fertilizer while neglecting phosphorus and potassium fertilizers, especially potassium fertilizer. Potassium deficiency in orchards can affect flower bud differentiation, the tree's cold resistance and fruit coloring, and can also reduce yield and fruit quality. When potassium deficiency is severe, the leaf margins or entire leaves scorch, spreading from the middle and lower parts upward and downward. After the leaves dry up, they can remain hanging on the branches for a long time. The leaves that have not withered curl and shrink, flower buds are small, and fruit color is poor.

Rational application methods and technical key points for potassium fertilizer
Strawberries bloom and bear fruit continuously, with many flowers and a large fruit load, and a long flowering and fruiting period, so they consume a lot of phosphorus and potassium fertilizer. Once phosphorus is deficient and potassium is low during the flowering and fruiting period, cold resistance will decrease, few flowers will form, flower buds will be weak, and flowering and fruiting will be affected. Not only will the fruit-setting rate be low and the fruit prone to deformities, but the coloring will also be poor, the sugar content will drop, and the taste will be bland, ...
