Why do farmers sprinkle plant ash on pakchoi seedlings for what use?

Abstract: why do farmers sprinkle plant ash on pakchoi seedlings? what's the use?

In the past, when cooking a pot at home, a pile of plant ash was produced by cooking a meal. At that time, the use of plant ash was to remove the smell in toilets, pig pens, chicken pens, etc., and finally cooked together with these feces to make farm manure. It is rarely scattered directly on the ground. So what are the uses of sprinkling plant ash directly on the cabbage field?

The main component of plant ash.

To understand the main function of plant ash, first of all, what are its main ingredients? Plant ash is called natural potash fertilizer, because its main ingredient is potassium carbonate, the content of potassium element is relatively high, even higher than that of special potash fertilizer. At the same time, it also contains some phosphorus elements, as well as some elements that promote the rooting and germination of crops, as well as activated carbon and so on.

The main use of farmers for sprinkling plant ash on Chinese cabbage.

As a natural insecticide, it can control pests. The leaves of pakchoi seedlings are relatively tender, especially after overcast and rain, it is easy to breed pests such as cabbage insects, and some ants will climb onto the plants and gnaw on the leaves. Therefore, farmers will sprinkle some plant ash around pakchoi to prevent pests such as cabbage insects and ants. Plant ash can also be washed in water and sprayed directly on the leaves of pakchoi. Plant ash is a pure natural insecticide, there is no problem of pesticide residues, it can be washed directly when eating, and it is one of the effective means for organic agricultural products to control diseases and insect pests. Plant ash can not only control vegetable insects and ants but also kill snail eggs, and it also has a good control effect on leek maggots in the root of leek. Because plant ash contains a certain amount of activated carbon, it can be sterilized and prevent the occurrence of rot.

Natural potash fertilizer, replenish fertility. The main component of plant ash is potassium residual acid, which is also a good farm manure. Sprinkling it in the cabbage field can supplement potassium fertilizer to cabbage, promote the root development of pakchoi, and then promote its absorption of nutrients in the soil, which can help to strengthen seedlings. At the same time, plant ash increases the drought resistance of Chinese cabbage by promoting the development of root system. The combined application of plant ash and chemical fertilizer can also promote the growth of Chinese cabbage seedlings. In addition, plant ash can also be sprayed as foliar fertilizer, foliar direct absorption, the effect is more obvious. Especially for cabbage and other cabbage leaf vegetables, the potassium fertilizer in plant ash can also promote the development of leaves and increase the taste of cabbage.

Will plant ash burn seedlings?

A peasant friend asked if plant ash could burn seedlings. In fact, plant ash will not burn seedlings if it is scattered directly in the ground, because it does not come into direct contact with Chinese cabbage. If it is foliar spraying, the concentration had better not be too high, because it is in direct contact with the leaves, too high concentration may lead to the phenomenon of burning seedlings.

Through the above analysis, we all understand the use of plant ash, the rest of the plant ash should not be thrown away directly in the future, it is a good potash fertilizer, you can consider sprinkling it directly in the ground.
