1, reducing soil water evaporation;
2. Adjust soil temperature to avoid over-exposure of soil in summer and extremely cold climate in winter;
3. Provide soil organic matter;
4, the dead leaves have high carbon content, which can prevent aphids from breeding;
5. Prevent the soil from hardening after the dead leaves rot.
The community is cleaning up the dead leaves in the green belt, bagging them and stacking them on the roadside for treatment. I carried five bags upstairs and prepared to retch several boxes with foam boxes and flowerpots. After spring, I will plant ginger to keep the water on the soil surface.
Last night, I couldn't wait to spread the dead leaves in the flowerpot. First, it can keep moisture, second, it can prevent aphids, and third, it can be used as fertilizer to loosen soil and increase soil permeability after decay.
Where there is space, it is covered with dead leaves. After a while, the leaves began to rot.
Last year, I didn't dare to pull leaves upstairs. This time, I really can't hold back. I mentioned six bags. You can't let the vegetable garden lack some elements just because you are afraid of pests and germs. In the rainy season in spring, water more tea cakes, and use water and a small amount of quicklime to make tea cakes. Killing snails and slugs plays a double insurance role.
In addition to covering, excess dead leaves can be used to make compost sandwiches. First put 2-3 cm of soil in the box (absorb the remaining fertilizer solution).
Spread a layer of dead leaves and sprinkle a layer of cake fertilizer. The picture shows the cake residue left after soaking, and the supernatant is used as topdressing.
Sprinkle it roughly evenly on the leaves and water it once, which will help the dead leaves rot faster.
Cover with a thin layer of soil, then cover with dead leaves and sprinkle with cake fertilizer. The next day, you will find dead leaves sinking, then you can add dead leaves and soil.
If possible, when making sandwiches, you can put fresh kitchen waste in the middle layer, which will decompose faster.
Three boxes were piled up on Saturday, 1 vat and 3 flower pots.
Sandwich compost can be transplanted with leafy vegetables when the surface is covered with more than 5 cm of soil. When the season comes down, fertilizers are piled up.
For fear that dead leaves will bring slugs, snails and germs, you can also sprinkle a layer of lime on the surface and then water it.
