Open field forcing culture method for tulip

Abstract

The invention discloses an open field forcing culture method for a tulip, which comprises the following steps: a harvested tulip seed ball is placed in a shady, cool and dry place for completion of flower bud differentiation, then is kept in a cold store at 5 DEG C for 10-12 weeks, and taken out before plantation; the outer membrane of the tulip seed ball is stripped, the tulip seed ball is planted in the soil, the soil surface is coated with a layer of straw mat cover, and the straw mat is taken away when the tulip seed ball sprouts in the spring of the second year; urea is applied for once after the tulip seed ball comes into leaves, then NPK compound fertilizer is applied after one week, and finally monopotassium phosphate is applied in a sprayed manner after bud occurrence. The method integrates multiple forcing culture manners, is simple to operate, can bring forward the flower season of the tulip for 7-10 days, and is suitable for planting the tulip in a large-area open field.

Description

technical field [0001] The invention relates to a flower cultivation method, in particular to an open-field promoting cultivation method of tulips. Background technique [0002] Tulip is a world-renowned bulbous flower, which has a wide range of application effects: medium-short varieties are suitable for potted ornamental plants, and medium-high varieties can not only be used as cut flowers, but also can be used to arrange flower borders, flower beds, cluster plants and sheet plants, which are very popular among people. garden flowers. my country has introduced and planted tulips from the Netherlands since the 1960s, and it is widely used in many cities in China. Its elegant posture and rich colors constitute a unique beauty in spring and are deeply loved by people. Many large cities in my country introduce and plant a large number of tulips every year, and the annual import volume of bulbs in the country reaches more than 60 million, mainly from the Netherlands.

Problems solved by technology

However, the flowering time of tulips cultivated in the open field in the northern region is relatively short, and the flowering period of a single flower is about 10 days. For the units that hold flower exhibitions, the viewing period is relatively short, resulting in an increase in the input-output ratio and a decrease in economic benefits. Therefore, by promoting cultivation The technology advances the flowering period and matches tulips of different flowering periods, which can effectively extend the viewing period of the flower show and improve economic benefits

[0003] There are some related reports at home and abroad on the research on the short-term flowering regulation technology of tulip cultivation in the open field, but the effects are different or not obvious enough

The main reason is that tulips are temperature-sensitive plants, that is, temperature is the main factor affecting their growth and flowering, but it is difficult to control the temperature of the environment in open field cultivation
