Plant ash is a common farmyard manure, so when should plant ash be used in garlic fields? Plant ash is the most common organic fertilizer in some rural areas, which can supplement potassium and loosen soil. Plant ash is what's left of burning firewood. In general, it is firewood ash cooked in a pot. Plant ash contains about 65,438+00% caustic potash, which is easily soluble in water. Plant ash is preserved by water, which will not reduce the fertilizer efficiency at all.

There are many rural friends, kind of garlic, who sprinkle some plant ash in garlic fields, which is very beneficial to the growth of garlic, and plant ash in garlic fields is made by experienced people in rural kind of garlic. So when should we use plant ash in garlic fields?

1 Late sowing garlic and plant ash warm garlic belong to a kind of potassium-loving crops. There is not enough potassium in the soil, so garlic is easy to peel thin and has poor disease resistance. Therefore, the potassium contained in plant ash is of very high quality. Plant ash has a dark gray surface, which can quickly digest and absorb natural light and heat. In the case of garlic planting, garlic petals are mainly used as seeds for planting. Garlic is usually planted after the 11 th National Day, and it can only be obtained in the spring after the cold winter.

Garlic can't be planted normally because of the weather. It is very late to grow garlic from the first frost solar term to the solar term in beginning of winter. At this time, the temperature is low and the garlic seedlings grow slowly. Even with plastic film, it is difficult for garlic to grow about 6 leaves before going to beginning of winter, because garlic seedlings with about 6 leaves are the most resistant to low temperature.

Low temperature in winter often leads to chilling injury of garlic planted too late. Plant ash will come in handy at this time. Sprinkling plant ash on garlic bed before mulching with plastic film, and then mulching with plastic film, can increase the soil temperature and reduce the chilling injury of garlic. Plant ash can't be sprinkled on the plastic film immediately. Garlic planted without plastic film in southern China can also play a role in preventing frost and moth by spreading plant ash around garlic seedlings in winter.

2. Before sowing in cultivated land, apply improved acid soil as base fertilizer. Garlic has been planted repeatedly for a long time, and chemical pesticides are used more. Soil is very prone to serious alkalization, which is harmful to the normal growth of garlic. Garlic likes to grow in slightly acidic and alkaline soil, and the pH value of soil is 5.5~6.0. If the soil pH is less than 5.0, it belongs to alkalization. Plant ash's principle of partial alkali can be used to improve soil.

After ploughing the land in autumn, before rotary tillage with a rotary tiller, sprinkle plant ash in the field, evenly sprinkle about 50 kilograms per mu, and then carry out rotary tillage. The effect of improving soil in plant ash is better than that of quicklime. In addition, plant ash can also be made into plant ash solution, filtered and sprayed with garlic.
