Detailed Explanation of Fertilization Methods and Techniques During the Sweet Potato Growing Period
How should sweet potatoes be fertilized during the growing period? Please advise. In the late growth stage of sweet potatoes, rational fertilization can prevent premature aging of the plants, maintain the assimilation capacity of the leaves, promote the transport of nutrients to the storage roots, and thereby increase yield. Foliar spraying: after sweet potatoes enter the late growth stage, the absorption capacity of the root system weakens, and foliar spraying can be carried out according to category...

How to fertilize ginger well? A detailed explanation of scientific fertilization methods
How to fertilize ginger well? A detailed introduction: the rhizome of ginger absorbs relatively little nitrogen, phosphorus and potassium during the seedling stage; during the vigorous growth period, phosphorus uptake increases slowly, while demand for nitrogen and potassium rises sharply. In particular, during the early part of the vigorous growth period, potassium requirement is highest, followed by nitrogen fertilizer; during the middle and late parts of the vigorous growth period, nitrogen uptake exceeds...

Key Technical Points for Spring Pest Control and Fertilization of Mulberry Trees
First, pest control must be strengthened. The pests harming mulberry trees in spring are the "mulberry looper" and the "mulberry tussock moth," which mainly feed on mulberry buds and tender leaves. For control, during the mulberry bud stage, a 1000-fold dilution of "dichlorvos" solution can be sprayed; once the mulberry leaves have grown larger, manual catching is the main method. Second, fertilize at the right time. Applying spring fertilizer promptly can promote...
