In the past two years, Eustoma was widely welcomed by the international market for its rich varieties and colorful colors. Domestic sales increased at a rate of 30% each year, and the average price in 2008 has reached 1.38 yuan per piece. At present, the planting area of ​​Eustoma in Yunnan is about 3,000 mu and 70% is produced from Tonghai. However, the biggest problem in the existence of Eustoma is that the proportion of high-quality flowers is small, the varieties are renewal slow, and the ability to undertake large international orders is limited. Producers need to work hard on management techniques, and the most important thing is to do field management. Li Jinze, an associate researcher at the Yunnan Academy of Agricultural Sciences' Flower Research Institute, said: “Eustoma bulbs are prone to problems with annual production, such as non-convulsions and undifferentiation of flower buds. To solve these problems, in addition to using quality seedlings, varieties suitable for the climate of Yunnan should be selected. For example, select mid-late-maturing varieties in cool regions and warm low latitude areas, and it is particularly important to do well in field management. Insulation or warming work during cold spells in winter should be done to avoid delays in flowering. Daytime temperatures do not exceed 30°C. Before the temperature rises, the plastic film on both sides of the greenhouse is opened to allow ventilation and cooling to prevent the high temperature and strong light from causing the top buds and tips to scorch. He said that the soil should be kept moist and evenly watered before budding. According to the growth and development of the plant, fertilize every 10 days or so by liquid fertilizer. Before budding to harvest, watering and fertilizing should be reduced, and attention should be paid to increased light. After one or two flowers are open on the stem, a small amount of shade is required to protect the flower and prevent fading. In addition, measures such as soil disinfection and appropriate rotation should be taken to prevent the occurrence of root rot. For the actual situation of the poor flowering season of the Eustoma grandiflora from August to September, good regulation of the flowering period can ensure that the cut flower prices are stable and maximize the benefits. Gong Xuehui, a professional cooperative of Tonghai Gongyang Emilia Campanulaceae, introduced the "earth approach" he had accumulated over the years: "The flowering period control technology that I developed benefited from a drought a few years ago and caused some echinocerems to suffer from insect infestation. Considering the secondary savings With the large purchase cost, I resolutely left nearly an acre of eustoma at the risk of spreading pests and diseases, cut plants 3 cm to 5 cm above the ground, and planted them in an attempt to cut most of them. Eustoma can be 'reborn,' regenerate new shoots, and produce good flowers. Hard work pays off, and the eustoma gradually returns to life. After more than a month, a good flower was opened and a good price was sold.†Gong Xuehui manages this from the field. The unexpected harvest was called "secondary treatment." The biggest advantage of this technology is the regulation of flowering time, which delayed the flowering period of the eustoma during the peak season by about one month. He said that although the use of chlorophyll can inhibit plant flowering, the flowering period can only be postponed by about 10 days, and the plant flowering during the regulation is unstable and the growth is not neat. Therefore, this year, facing the worst drought in a century, he encouraged everyone to use fewer of these chemical hormones to guide the production of flower farmers, and introduced his “secondary treatment†technology to flower growers. In terms of varieties, Xia Yu, deputy general manager of Yunnan Tonghai Ruiyuan Flower Industry Co., Ltd. said: “According to the climate characteristics of Yunnan, especially Tonghai, after many years of exploration, the varieties that are more suitable for planting are 'Mary', 'Shelley', and 'San'. There are more than 60 varieties such as 'Sword', 'Myth', 'Lulu Tower', 'Northern Light' and traditional '701' and '702' varieties. In the winter, some late-maturing varieties should be selected from the above varieties for planting.†It is emphasized that as of now there are no domestic standards for the production of eustoma, and it is difficult to achieve quality improvement only through foreign production management techniques. Therefore, based on years of experience, they have summarized a set of production management techniques and experiences suitable for the region. In response to climate problems such as large temperature difference between day and night, and low temperature frost in winter, the problems such as plant dormancy and blade foliation are raised. He proposed to control the temperature difference in greenhouses, and provide timely ventilation and insulation. Under normal circumstances, open the tent after 8 am, close the booth before 7 pm, and use thermal insulation film at night. If necessary, you can use the air conditioner to warm up or add light to warm the temperature. The temperature in the night canopy should not be lower than 7°C. In addition, Xia Yu suggested that it is best to use high-quality seedlings grown abroad when the domestic seedling propagation technology is not yet mature. Although the cost is 15% to 20% higher than domestic self-producing seedlings, the comprehensive economic benefit of cut flowers is higher by 30%. 40%.
