Rejuvenation skills of weak seedlings of Orchid

First, use small pots. Because most of the weak seedlings have poor root system development, such as using large pot species, the plant materials are many and thick, easy to accumulate water, and the moisture is heavy after watering, and the temperature in the basin rises slowly, which is not conducive to rooting and sprouting. Second, planting new materials. Because the new plant material does not contain fertilizer, less disease and insect pollution, it is conducive to the root growth of weak orchid. Third, deep planting is suitable for moistening. Weak seedlings generally have few or no roots, and mainly rely on pseudobulbs to maintain water supply, so the key to planting and breeding is to keep the plants around the pseudobulbs moist. The purpose can be achieved by using the deep planting method (that is, burying the false bulb with plant material about one centimeter high). If you use soil species, you only need to bury the false bulbs. Fourth, avoid applying fertilizer. The physiological function of weak orchid itself is weak, which belongs to a kind of morbid. In this case, if re-fertilization, it is tantamount to making things worse, not only can not be rejuvenated, but will accelerate death. Fifth, the last point to note is that the weak orchid should be specially placed in a place of the orchid frame, not mixed with other strong seedlings, so as to facilitate management and observation.

As long as it is a healthy seedling, bask in the sun as much as possible, don't be afraid of scorching tips, the old seedlings retire quickly, but the new buds are also strong. The old man Miao, as long as the new root, the new seedling and the old man should be separated in time, so that he does not have anything to rely on. Weak seedlings do not apply fertilizer is misleading, as long as healthy, the growing season can use fresh liquid fertilizer once a week. Granular plant materials do not pay attention to dry orchid and wet chrysanthemum, especially in summer, should be watered more. First of all, cut off the burr formed by the decay of the leaf beetle, and then use a toothbrush to clean the soil and rotten tissue from the Reed head under the faucet, in order to bring the Reed head into close contact with the plant. Brush gently, too rude to brush the bud, will become a thousand-year-old man. The rest of the beard from the rotten root should not be cut off. Although it does not have the function of absorbing nutrients, it can fix the plant, absorb water and transmit it to the Reed head. Cut off 2/3 of the leaves to prevent the water from evaporating too quickly and make the Reed head dry. It is reasonable to cut off the crown of trees when transplanting trees in summer. When on the basin, the lower 3/4 of the plant material is the ordinary plant material, which should be nutritious so that the new buds can absorb nutrients as soon as possible after taking root and prevent toothpick seedlings. The upper 1/4 should be fine-grained planting stone, as thin as possible, and can be mixed with some fine foam of weathered rock, in order to make the contact surface between the plant and Reed head as large as possible, and moisturize. If the particles are large, there is only a little contact between the plant and the Reed head, and no matter how much water is poured, it will not keep the Reed head wet. After putting on the basin, put it in a sunny, leeward place to keep the basin surface moist in order to make the basin soil temperature as high as possible and promote germination. Put it in a cool and ventilated place in summer to prevent the sun from drying the seedlings into dried orchids, hehe. A few days ago, I received a rootless Lijiang snow from Lanyou. With this treatment, it sprouted in less than a month. First: weak seedlings are not easy to grow alone, it is best to find a pot of similar plant type, luxuriant growth, developed roots of orchids with the original pot of the old plant material, such as weak seedlings grow into medium-strong seedlings, and then separate and replanted. Second: it is best to use fine-grained plant material for weak seedlings, plant material rich in organic matter under the Reed head, and plant gold stone with fine particles at the bottom of the Reed head. When going up the basin, a few grains of magic fertilizer are put in the middle of the basin as base fertilizer, so that the new seedlings can absorb nutrients in time after rooting. The Reed head of the weak seedling should be filled with finer wind fossils, in order to keep the Reed head moist as far as possible, so that the new root can come into contact with the "earth atmosphere" in time to prevent stiff buds and new root blackheads, because the root system of the weak seedling is underdeveloped. the roots and buds are generally not strong, and the particles around the Reed head bud point are larger, if the initial stage of germination and rooting is dry, it is difficult for new shoots and new roots to grow. The upper part of the ultra-fine particles is covered with a layer of fine planting stone to prevent watering from being washed away.
