Method for growing seeds of eucalyptus seeds and purple magnolia
The cycads are called cycads in botany. They are also known as phoenix, bananas, bananas, bananas, cycads, cycads, and cycads. Originated in Central and South China, India, Japan and Indonesia, originated in East Asia and Southeast Asia. Zhejiang, Fujian, Hunan, Sichuan and other places are widely cultivated. Potted plants are provided for indoor viewing in North China and Northwest China. Cycads like sunshine, dry and well-ventilated environment, not cold, good fat, hi sandy soil, slow growth. The cycads can reach a height of 8 meters in the country of origin, and can be up to 3 meters high in houseplants. The stems are in a thick cylindrical shape with no branching and large leaf marks forming ichthyosis. The cluster of leaves is born on the top of the stem and is a large feathery compound leaf, about 1 meter long. Leaves linear, leathery, hard-edged, thick green with luster, leaf margin rewind. Every spring, 2 or 3 rounds, the old leaves fall off; flowers are unisexual, born on the top of the stem, dioecious, male flowers spirally arranged, resembling a pineapple, being velvety, fresh yellowish at the beginning, becoming mature after brown. The female flowers are large, with a large number of palm-like scales, a flat cylindrical body that gradually splits to form a pine cone. The cycads rarely flowered. The old trees in the 20s to 30ths can bloom. It is called "a millennium-old iron tree." The flowering period is from June to August. Cycads are mainly propagated in litters and can also be sown or propagated in cuttings. Seeding and propagation: In October, harvest cycad seeds or full seeds for no more than two years, soak them in warm water of about 50°C for 24 hours, then soak in diluted hydrochloric acid or dilute sulfuric acid for 10 to 15 minutes, and then rinse with water. Change the water one time every other day. After the seed coat is fully water-absorbing and softens, remove the outer seed coat manually, wash away the pulp, dry the seeds, and then store them. Seed sand treatment is performed around December. Because of its thick and hard seed coat, it can be treated with a variable temperature method and finally sanded. Use a clean sandy soil, river sand, perlite and other water-retaining, well-breathable materials to make seedbeds with a thickness of no less than 40 cm and be irrigated with water. The prepared seeds are sown in a bed at a spacing of 5 to 20°C. The depth is about 3 cm. Immediately cover the river sand with a thickness of 3 cm, control the amount of water on the bed and the dryness of the covered fine sand, and then cover the plastic film to moisturize the water after pouring the water. Select the sunny day every morning to open the membrane and let it breathe once. The soil is dry. Watering should be kept moist, cover the film in the afternoon and sunset, and it usually takes 4 to 6 months for the cycas deposit. During this period, the temperature and humidity of the sand should be maintained, and the temperature should be 18 to 25°C and the relative humidity should be 80 to 90%. In order to keep warm in winter, it must not be lower than 12°C. In the second year of May to June the seeds germinate and break out of the shell, and from July to August germination grows a true leaf. Breeding: In the summer, the buds should be separated from the stems of the mother plants, inserted into the open or pot, half of the earth buried, and the survival rate of the ramets can be as high as 80 to 90%, and the sucker growth is slow. It is better to take out the buds after 3 years. The sucker wounds are easy to live. The stem can also be cut into long sections of 15 to 20 centimeters and buried in sandy soil to create new shoots around the cadres and then subcultivated. The cycads are suitable for growth in direct sunlight or under bright scattered light. Summer is best shaded half, the temperature is maintained at 15-20°C, the soil and air humidity are greater, and the leaves should be sprayed frequently. The plant does not have a dormant period, and the winter temperature is preferably 12 to 16°C, and the plants have a considerable degree of cold resistance. Between 3 and 9°C months, liquid fertilizer should be applied once a month. It is advisable to use a mixture of organic matter, peat and fine sand as the substrate for cultivation. Every 2 to 3 years, change the basin soil, add new soil and basal fertilizer to help grow. Liquid fertilizer can be applied several times in summer, and ferrous sulfate solution can be added to make the leaf color more dark green. After the fall, the amount of watering is reduced. The pests and diseases of cycads are most commonly caused by scale insects. The first step is to maintain good ventilation and find the scale insects. Observe the limestone mixture or fluoroacetyl ammonium at hatching. Purple magnolia, also known as magnolia, magnolia, wood pen, magnolia tree is a deciduous tree. Normal flowering period In late March, the first leaves are open or mosaics are placed. Purple Magnolia Hi light, slightly shade-tolerant, hi warm and humid climate, but also has a certain degree of cold resistance, can safely overwintering around -10 °C. Because it is a fleshy root, it is not resistant to stagnant water. In the northern cultivation, the leeward sunny place should be selected, and the seedlings must be protected during the winter. Transplantation should be carried out before and during the autumn and early autumn. If transplanting in the fall, the time should be chosen so that the plants can take root and grow before the frost. Purple magnolia is a fleshy root, so transplants are required to bring earthworms. Suitable for cultivation in well-drained acidic or neutral sandy soil, avoid salty soil. To keep the soil moist during the growing season, timely watering should be done during the dry season. Fertilizer plants should be applied to the soil every year to promote its robust growth. Saplings should be careful to cut dead branches, cross branches and internal litchi, so that it is airy and transparent, beautiful plant shape; but generally do not need trimming after mature, can be naturally formed. Purple magnolia uses seeding, grafting, cuttings, layering and propagation. The fruits are red and flaky and the seeds are harvested. The seeds are peeled off and dried, and then the sand is collected. In March of the next year, the seeds are sown in the room and emerged in about 20 days. In May, they are transplanted into seedbeds or nurseries. They can be grown from two to four years. Planting colonization. Grafted with wild magnolia or white magnolia as rootstock, cut or spliced ​​before budding in the spring, from May to August with buds. A small amount of family breeding, it is appropriate to use high air pressure layer method, use robust and well-shaped branches, ring peeling under the festival, deep to the xylem, with moss or plain soil, external plastic film wrapped tightly, often keep the substrate moist. After the autumn of spring, the pressure was cut off and the autumn pressure was cut off in the spring of the following year.
