Why do we spread wood ash when planting? How to apply wood ash when planting ginger?

Wood ash is the ash left after burning firewood. It is very common in rural areas. Moreover, wood ash can be reused, such as being sprinkled on crops or made into flower fertilizer. So why do we also sprinkle wood ash when farming? Can we sprinkle wood ash when growing ginger?

Why do we spread wood ash on the land?

Farmers sprinkle wood ash on grass and crops mainly because wood ash contains a variety of mineral elements that can meet the needs of crop growth.

Wood ash is an alkaline fertilizer. When it comes into contact with water, it heats up the soil and speeds up the germination of crops. It can also heal plant root injuries. For example, if the roots are damaged during transplantation, wood ash is very effective in repairing old roots and growing new roots. In addition, wood ash can also enhance the glossiness of the leaves of vegetables and turf.

In addition, if you have fish, a proper amount of grass ash in the fish pond can improve water quality and promote the growth of fish. But in the process of using grass ash, do not mix it with acidic fertilizers, pesticides, human and livestock feces, and keep it dry.

How to apply wood ash to ginger planting

At different stages, the nutritional supply required by ginger is different, so the topdressing of wood ash should be based on the needs of farmers, so as to better benefit the wood ash and promote the high yield of their own ginger.

First of all, when sowing ginger for reproduction, when the tender shoots of ginger just come out, they need suitable temperature and effective light-blocking effect, so the topdressing of wood ash during this period can not only keep warm, but also effectively block light and effectively promote the nutrient supply of ginger seedlings.

The most common choice of topdressing with wood ash is during the growth period of ginger, because ginger grows vigorously. Timely supplementation of wood ash is necessary. Wood ash contains potassium carbonate, so it is necessary to timely supplement the nutritional supply required by ginger. At the same time, wood ash has a certain bactericidal effect, and it is also good for preventing and reducing the occurrence of pests and diseases. When planting, covering the ginger with a thickness of about three centimeters can play a shading role and inhibit the growth of weeds, killing two birds with one stone. Do not plant ginger in succession, as it is easy to breed harmful bacteria.

Can wood ash prevent spider mite disease?

Plant ash does have a certain effect in some cases of minor red spider damage. Applying 2.5-5.0 kg of plant ash under each fruit tree can prevent root rot; spraying 2%-3% plant ash extract on the leaves can prevent aphids, red spiders, etc.; mixing finely ground tobacco with plant ash in a ratio of 1: (3-6) and sprinkling it on the trees before the dew dries can prevent aphids, leafhoppers, leaf miners, caterpillars, etc.

However, the amount must be controlled and not too much should be used to avoid weakening the respiration and photosynthesis of the plants. And if there is no good effect in the early stage, it is necessary to use insecticide to treat the red spider in time to avoid delaying the damage to the plants. And the wood ash must be dried in the sun when used.
