The name of the orange trachea is: eustona grandiflourum shinn lisanthus russe lianus hook; the english name: eustoma. Lisanthus, prairie. Gentiana texas bluebell; the herbal flower of the dragon's gall. Orange pellets are one of the new and emerging cut flowers that have developed rapidly in taiwan in recent years. They are beautiful, colourful, purple, white, yellow, pink and white-floored, purple, pink, and so forth. They are very new and beautiful. Cut flowers are water-absorbing, bottles have a long life and most buds continue to grow and are open in sequence. They are popular because they are modern, especially purple flowers, and they are used in the summer. Orange infarction during childbirth is sensitive to changes in the growing environment, such as changes in temperature and dry and wet soil, and the length and strength of sunlight. The environment and management practices that adversely affect the growth of orange infarction are prone to convulsion or poor growth。
(i) sowing and flowering periods
The number of days necessary to sow seedlings to plant flowers varies considerably depending on the month in which they are planted. In the central part of taiwan, the minimum number of days to sow in the spring to bloom is about four months, but during the high-temperature season of august and september, the number of days increased dramatically, reaching eight months, twice the difference. As for the length of cut flowers, the highest growth was in the plants planted in december and more in april。
(ii) reproduction
Despite the use of admixtures and tissue culture, it is still mainly seed-based. Seeding can take place 30 days after harvest. The seed of the orange infarction is quite small, is a good light seed, is planted without covering, and the light is kept above 5,000 lax: good. The sprout temperature is 15-30°c and 20-25°c is ideal. At 15-20°c after gerontation, the temperature at 25°c. ... Will prevent foliage and breed good seedlings. The soil will be required to maintain a constant moist state, preferably with a nuanced effect from the bottom, and normal water management will not gradually reduce moisture until the first leaf spreads in order to produce a strong plant. The fertility rate used for seeding should not be high ... To maintain the conductivity (ec value) of 0. 2 ~ 0. 4 ms/cm and to dilute the concentration of 2000 ~ 4,000 times (20-20) with one application per week or 10 days depending on the growth of the plant。
(iii) selection of seedlings
Growing a seedling or not has a great impact on its success. Leafing also inhibits the extension of later periods, the more warm and prolonged the night, and the more inhibiting the length of future flowers. Normal seedlings differ slightly from seedlings that tend to corrode. A normal-growing sapling of 5. 6 leaves will grow on a slope, and sections 3 and 4 will start to grow long; the latter, with leaves on the surface, will also be more tiring and condensed。
(iv) plantation
The ph values were adjusted to 6. 5 ~7. 0 per 0. 1 hectare per 100,000 hectares of corroded compost and approximately 10-15 kg each of the triples. In order to reduce the incidence of pests and diseases, soil disinfection is desirable. The ideal planting seedlings... Are those that have 4-6 leaf blades and have no tendency to corrosive. When planted, the earth should be kept in a wet state, not in dry condition, and if the plant suffers from water shortages, it can easily lead to corrosion ... And even affect life and future development. Before planting, a web of 12-15 centimetres of squares can be laid to the surface and planted in order in each cell, and if two or more seedlings are formed in the den, do not, to the extent possible, strip to the ground. It is better to plant than deep ... Than to plant ... Within 10,000 plants per 0. 1 ha. The planting should be carried out in such a way that the soil is not dried to avoid adverse effects on the fertility of the plant。
(v) post-plant management
Due to the reproductive nature of the orange infarction, the temperature and the dry and wet changes in the soil are sensitive and require greater attention in management. If the minimum night temperature is maintained at more than 15°c and cold currents come in, it must be kept warm or warmed; in the daytime, plastic sheeting should be removed, suitable for temperature rises within the midday shed, at no more than 30°c, so that it may be ventilated, so as to prevent excessive changes in the temperature, thereby impeding normal fertility of the plant, leading to the occurrence of disease and physical disorders, such as temperatures exceeding 40°c and high daylight, which can cause daily burning and burning at the top of the buds and leaves. Fertilization can be applied at concentrations not exceeding 1. 0 ms/em (more than 1,000 times diluted in the case of flower 2), depending on the development of the plant, approximately every 10 days。
(vi) the problem of condensation
During the high-temperature period between june and september of the summer, the average temperature was above 30°c, so that seedlings of sundown seedlings were planted, which tended to be easily transported into unique clusters. In the case of folicization, this seedling is difficult to address in the short term to improve into a normal gravitational plant. According to japanese scholars, ... Before planting, four to six weeks can be treated at 10°c low temperatures, and then planting can have an improvement, but in the dark cold storage, it is best to be illuminated with light above 500 lax after the third week. Test observations at the flower study chamber indicate that after planting in the summer, two weeks after seeding, then four weeks after cooling at 16-18 c, most varieties can have a extraction rate of more than 50 per cent。
(vii) photoprocessing
Due to the non-absolute long-day plant of orange infarction, which produces a normal plant, in a 16-hour long eight-hour environment, the effect is to promote the early formation of buds, buds and early blooms, while at the same time allowing for long festivities ... To increase the number of buds ... To improve the quality of cut flowers. It is common for oranges to be planted in the low-temperature autumn winter. Electricity treatment ... Can often be used to achieve these effects. Note that the minimum night temperature should remain above 13°c. - a normal plant can grow up to a height of 10 cm after planting (approximately after chrystalization) before giving birth to a child in a natural short-day environment, before it begins to be given up in the middle of the night, in september for two hours, in october 3 hours, and in november - february of the following year for four hours, before the flowering period. If, on the other hand, after planting, only the first half of the entire reproductive period is electrocuted, which is then allowed to grow in short-lived conditions, the delay in harvesting or the reduction in the number of cuttings at the time of harvest may result in the reduction of the number of buds or even the reduction of them。
(viii) growth control agent treatment
A weekly spraying of gas 25 ~ 50 mg/l at the onset of a squirt can contribute to the extension and quality of the cut flowers。
(ix) cut flowers
The earliest buds can be removed at an early stage and collected when more than two to three flowers are opened, improving the quality of the cut flowers and increasing the cut flowers ' lifetime by subsequent water insertion。
