Embodiment 1
[0020] When the continuous cropping obstacle of eustoma is serious or the incidence of eustoma wilt is high, the plot shall be subjected to strong reduction treatment, and bagasse shall be added to the soil at a ratio of 0.5kg C / m 2 , plow the soil, the plowing depth is 30cm, irrigate the soil, and the irrigation water volume is 0.10 tons / m 2 , and then covered with a plastic film to isolate the gas exchange between the soil and the atmosphere, and maintained a strong reduction treatment for 2 weeks, with an average temperature of 40°C during the treatment. After the treatment is completed, the plastic film is uncovered, and the eustoma is routinely planted. Control 1 did not add bagasse to the soil and did not cover it with plastic film, but only plowed and irrigated with the same parameters as above, and eustoma was planted after 2 weeks of vacancy at 40°C.
Embodiment 2
[0022] The process steps are the same as in Example 1, and other parameters are shown in Table 1.
[0023] The process steps of control 2 are the same as those of control 1, and other parameters are shown in Table 1.
Embodiment 3
[0025] The process steps are the same as in Example 1, and other parameters are shown in Table 1.
[0026] The process steps of control 3 are the same as those of control 1, and other parameters are shown in Table 1.

Abstract
The invention discloses a continuous cultivation method of eustoma grandiflorum. The continuous cultivation method comprises the following steps: in the case of serious continuous cropping obstacle of the eustoma grandiflorum or higher wilt morbidity of the eustoma grandiflorum, controlling the soil to be higher than 25 degrees Celsius, carrying out strong reduction treatment on the land, and continuing to conventionally plant the eustoma grandiflorum after the strong reduction treatment; after continuous cropping of 1-2 years, carrying out the strong reduction treatment on the soil again, and continuing to conventionally plant the eustoma grandiflorum, and repeating the process to continuously plant the eustoma grandiflorum on the same land for a long time; and the specific process of the strong reduction treatment is as follows: adding bagasse or molasses to the soil, ploughing to uniformly mix the bagasse or molasses with the soil, then irrigating the soil to the maximum field capacity, and finally covering a plastic film on the land to isolate the gas exchange of the soil and the atmosphere. By adoption of the continuous cultivation method provided by the invention, effective guarantee can be provided for continuous production and soil resource protection; and moreover, the continuous cultivation method has the advantages of low cost, high benefit, simple operation and easy popularization in production.
Description
technical field [0001] The invention relates to the technology of protecting and agricultural land management and agricultural utilization, and specifically relates to a continuous cultivation method of eustoma. Background technique [0002] Eustoma grandiflorun (Enstoma grandiflorun) is an ornamental plant of Gentianaceae Gentiana, native to the United States and Mexico. Eustoma was originally an ordinary wild flower. With the advancement of breeding field, especially in the past 10 years, the breeding and production of Eustoma have developed rapidly, especially in Japan, where purple, pink, white, and blue flowers have been bred. Variety of flower colors such as pink, lavender, white flowers with pink borders or white flowers with purple borders, as well as bell-shaped corollas, funnel-shaped corollas and other varieties of flowers. Lisianthus eustoma has elegant and beautiful flower posture, charming and charming, unusually novel, and the effect of flower arrangement is ...
