How to breed Oxalis

Oxalis is mainly propagated by bulbs and individual plants, and some are propagated by seeds.

The conjoined stems of Oxalis can be divided into three types: mother corm, bud corm and leaf corm. Among the three kinds of bulbs, the female corms have direct meristematic corms with a diameter of 2 to 2.5 cm, with residual leaf scars and latent buds at the leaf scars, which can germinate and grow into corms successively. The bud bulb is a young bulb growing on the female corm, with a diameter of about 0.5 to 0.8 cm. A leaf corm is a leafy bulb that grows from a bud corm and can blossom, about 1.2 to 1.5 cm. When it grows and develops, it becomes a female corm.

According to the experiment, the reproduction coefficient of single bulb is high, and about 15 to 17 corms can be obtained per single corm on average. The survival rate of mother corm and leaf corm planted in the open field was almost the same, but the reproduction coefficient of leaf corm was the highest. There was no significant difference in the survival rate of sorrel cultivated in different periods, but there were significant differences in corm size and species.

Under the same circumstances, the propagation of sorrel is mainly in the spring and autumn. In order to increase the reproduction coefficient, on the basis of dividing the bulb, the bulb can also be cut into 2 to 6 petals according to its size. The bulbs cultivated for two years can reproduce 20 to 30 plants each with high survival rate and fast growth, and can blossom in about one month.

Sorrel can also grow in the same soil, but it grows fastest in rich, loose and well-drained sandy soil. The growth is slow in the hot season and is basically in a dormant state. Apply organic fertilizer once a month during the growing period and water it in time. Oxalis is easy to be harmed by red spiders. If it is not controlled in time, it can cause yellow leaves, dry up, few flowers, and affect the ornamental value. Therefore, during the growth process, the grass can be sprayed with 1000 to 1500 times of omethoate, 0.2 to 0.3 degrees of stone sulfur mixture, and acaricides.

Morphological characteristics of safflower sorrel stem safflower grass (Yintong "vinegar") perennial erect herbs. There is no aboveground stem, the underground part has globular bulbs, the outer scale is membranous, brown, the back has 3 ribbed longitudinal veins, long ciliate, the inner scale is triangular, glabrous. Leaves basal of sorrel; petiole 5-30 cm long or longer, hairy; leaflets 3, oblate-obcordate, 1-4 cm long and 1.5-6 cm wide, top sunken, rounded on both sides, base broadly cuneate, surface green, hairy or subglabrous; abaxially light green, usually with brown-black glands on both surfaces or sometimes only edges, especially abaxially and sparsely hairy.

The flowering and fruiting period of Oxalis safflower is from March to December. The ecological habits of safflower sorrel prefer to the sunny, warm and humid environment, and the hot areas in summer should be shaded, drought-resistant and not cold-resistant. North China needs to be cultivated in a greenhouse in winter. To the south of the Yangtze River, it can stand in the open field and like the overcast and wet environment. It has strong adaptability to the soil, and the general garden soil can grow, but the sandy loam rich in humus grows vigorously and has a short-term dormancy in summer. It is easy to open up when the sun is very good. Cultivation techniques of safflower sorrel seedlings dig up the whole aged seedlings with a shovel, gently pat off the persistent soil around the root system, and concentrate on stacking. Dig seedlings a little further away from the plant, so as to avoid accidental injury to the bulb, and pay attention to the spade to dig straight down, not obliquely dig down, hurt the bulb. The ramet removed the withered leaves and removed about 1 / 2 of the old leaves to reduce transpiration and water loss after planting. The lower old bulb should be cut off with a sharp knife, and the incision should be under the first or second new bulb, so that the seedlings with 1 or 2 new bulbs can not only remove the lower old bulb, renew and rejuvenate, but also ensure that the new plant has enough nutrients to sprout and blossom quickly. Finally, in the cut new bulb wound, dip it with fresh plant ash to prevent the wound from rotting. Apply organic fertilizer in the flower bed where the aged seedlings are dug up, turn it over again and rake away the withered leaves and weeds. Generally, 0.5-0.8 kg / m ~ 2 of rotten cooked cake fertilizer and appropriate application of phosphorus and potassium fertilizer were applied to ensure the flowering needs of safflower sorrel. The planted safflower grass grows rapidly, and each plant can reproduce 3-9 seedlings in the same year. When planting, the character-shaped hole planting is generally used, and the row spacing is 25 × 35 cm. Dig a hole 8 cm 10 cm deep with a small shovel. According to the size of the bulb, put 4 trees in each hole and cover the soil 3 cm. Pay attention to exposing the leaves to the surface of the soil. Of course, you can also use the method of trench planting, the row spacing is generally 15-30 cm, and water it after 2-3 days of planting to prevent the bulb from rotting. Maintenance points: Carthamus tinctorius is easy to survive, strong growth potential, long florescence, deeply loved by the majority of people. However, due to the extensive daily management, there is a phenomenon of only planting and ignoring in many areas. Resulting in the growth of safflower sorrel for many years, the plants crowded with each other, the roots moved up, the ability to absorb fertilizer and water weakened, the growth weakened year by year, the number of flowers was reduced, the flowering period was shortened, and the serious areas withered, affecting its ornamental value. According to many years' cultivation experience, the author analyzes the causes of aging and introduces the methods of rejuvenation. The reason for aging is that the bulb under the grass of safflower sorrel is fusiform, covered with brown hard skin and terminal bud. After the terminal bud is damaged, a large number of surrounding axillary buds germinate, and adventitious roots can be produced at the base. When the temperature rises in spring, the safflower grass begins to tiller, and the base of the plant growing on the bulb gradually expands to form a new bulb. This tiller occurs about twice a year, the first after a large number of green in spring and the second at the end of summer dormancy. With the increase of the number of tillers and the growth of new bulbs, the bulbs continue to move up, so that the root system gradually close to the ground, this phenomenon is called "jumping root". According to the author's observation, the second to third year after planting is the peak tillering stage, and there are more flowers. After 5 ~ 6 years, the tillering ability gradually weakened, most of the bulbs had jumped more than 5 cm above the ground, the growth was obviously weak, vulnerable to sunburn and freezing injury, and easy to be infected with diseases and insect pests. The interior of the new bulb was milky white, while the aging bulb at the bottom of the cross-section showed moderate red and Lignification. The regeneration and rejuvenation of Carthamus tinctorius is easy to plant and live. Regeneration and rejuvenation can be carried out in combination with the anniversary of ramet reproduction, and the best ramet time in North China is from the beginning of March to the end of April. At this time, the survival rate of rejuvenation and planting was high, and the growth and ornamental effect of safflower sorrel were not affected. In addition, the summer dormancy of safflower sorrel is also a good period for rejuvenation. Strengthening the management and strengthening the daily maintenance management of safflower sorrel can also effectively delay the occurrence of its aging phenomenon. The flowering period of safflower sorrel is more than 5 months, and a lot of fertilizer and water are needed during the growth period, so it should be fertilized and watered in time in the growing season. Before turning green in spring, 15-20 kg compound fertilizer per mu can be applied, and it can also be sprinkled according to soil moisture combined with watering. After that, fertilize every 20 days except dormant period, and pay attention to the prevention and control of diseases and insect pests. With the increase of temperature from July to August in summer, Elaeagnus angustifolia was forced to go into dormancy and basically stopped growing. In order to prevent the sunburn harm caused by the new stem exposed to the soil, cover the soil. The thickness of soil cover should be determined according to the height of the new stem of Carthamus tinctorius each year, which is generally 2-3 cm. Safflower sorrel steppe is produced in Brazil, likes the shady and wet environment, and requires sandy loam with good drainage and high content of humus. It is not hardy and can only be cultivated in greenhouse in colder areas. The propagation mode of safflower sorrel no fruiting phenomenon was found in Tengzhou City, but corm propagation and ramet propagation were the main propagation methods. Ramet propagation is carried out in the spring and autumn, when the underground stem is full, new buds have been formed, can be planted by hand, it is very easy to survive. Cutting stem propagation should be in spring, the survival rate is higher, cut the bulb into pieces, each with 2-3 buds, planted for more than a month can send out new leaves, can blossom in the same year. The propagation coefficient of single corm in rapid propagation is high, and the average number of corms per single corm is about 15-17. The survival rate of mother corm and leaf corm planted in the open field was almost the same, but the reproduction coefficient of leaf corm was the highest. According to the experiment, there was no significant difference in the survival rate of Carthamus tinctorius cultivated in different periods, but there were significant differences in corm size and species. In general, the propagation of Carthamus tinctorius is mainly in Spring and Autumn period. In order to increase the reproduction coefficient, on the basis of dividing the bulb, the bulb can also be cut into 2-6 petals according to the size. The bulbs cultivated for 2 years can reproduce 20 to 30 plants, have a high survival rate and grow fast, and can blossom in about 1 month. Sowing and propagation of safflower sorrel can also grow in general soil, but it grows fastest in fertile, loose and well-drained sandy soil. Planting should not be too deep. Apply organic fertilizer once a month during the growing period and water it in time. During the growing period, we should pay attention to watering, keep it moist, and apply fertilizer for 2 or 3 times to keep the flowers blooming and leaves luxuriant. The growth is slow in the hot season, basically in the dormant state, should pay attention to stop fertilizing water, put in the shade, protect the summer. Fertilizer and water management should be strengthened during the peak growth period in winter and spring. The disease control of safflower sorrel is easy to be damaged by red spider. if it is not controlled in time, it can cause yellow leaves, dry up, few flowers and affect the ornamental value. Therefore, in the process of grass growth, 40% omethoate 1000-1500 times, 0.2-0.3 degree stone sulfur mixture, and acaricides can be sprayed.
