Some plant species can "coexist peacefully, survive and prosper", while some plant species can "use the strong to bully the weak, and are incompatible with water and fire". In flower cultivation and maintenance, how to avoid the dangers To overcome and eliminate harm by using benefits should indeed be taken seriously.
Due to different species and different habits, some plants, in order to compete for nutritional space during their growth, secrete toxic substances from their leaves or roots that are lethal to other plants, causing them to He and other neighboring plants "become enemies and become injured, life and death".
For example, the roots of walnuts can secrete a substance called juglone. After hydrolysis and oxidation in the soil, it is extremely toxic and can cause pine, apple, potato, tomato, birch and many other diseases. Plants and vegetation are damaged or killed.
Some plants, due to different species and complementary habits, can use secretions from their leaves or roots to each other, allowing them to "mutually benefit and live in harmony." If you plant violets in a vineyard, the quality of the grapes you produce will be better. If soybeans are mixed with castor, beetles that harm soybeans will be driven away by the smell of castor.
Of course, when planting and cultivating potted flowers, since they are not planted in the same pot, the influence of root exudates does not need to be considered. Only the influence of leaves, flowers, and fruit exudates on plants placed in the same indoor space can be considered. of other flowers.
For example, lilacs and lily of the valley cannot be placed together, otherwise the lilacs will wither quickly. Even if they are 20 cm apart, if the lily of the valley is removed, the lilacs will return to their original shape; lily of the valley cannot be placed with daffodils. Together, otherwise both sides will suffer losses. Lily of the valley has a particularly bad "temper" and is not "friendly" enough with almost all other flowers; the fragrance of lilac is also not good for narcissus, and may even endanger the life of narcissus; lilac, violet, tulip and Don't forget yourself, don't plant them together or put them in the same vase, otherwise both will suffer. In addition, cloves, mint, and laurel can secrete a large amount of aromatic substances, which have an inhibitory effect on the ecology of adjacent plants. It is best not to place them together with other potted flowers for a long time; the volatile oils of juniper contain ethers and trichlorotetraxane. , will slow down the respiration of other flowers and plants, stop their growth, and cause poisoning. Do not place junipers together with pears, crabapples and other flowers and trees, otherwise they will easily get rust. Furthermore, it is best not to place ripe apples, bananas, etc. in the same room as budding or blooming potted flowers (or flower arrangements). Otherwise, certain gases produced by the fruits will cause the potted flowers to wither early, shortening the viewing time. .
The types of flowers that can get along well include: lilies and roses planted or vase together will bloom better than if they are placed alone. Nasturtiums with a flowering period of only one day can be extended to 3 days if placed together with cypress trees; camellias, sasanquas, safflower camellias, etc., placed together with litsea cubeba, can significantly reduce mildew diseases.
