Problems solved by technology

[0006] Chinese patent CN104106328A discloses a method for germination of cattail seeds in Northeast China, including the collection and storage of cattail seeds, seed pretreatment, seed screening, sowing, seed germination and other processes. The method of treatment solves the problems of high cost and high mortality in the process of transplanting cattails
However, this seedling raising method has a large demand for water and needs to be implemented in paddy fields. It is more suitable for promotion in areas with abundant water resources and fertile soil, such as Northeast China, and is not suitable for use in areas with relatively poor soil. , this method focuses on improving the germination rate and emergence rate of cattail seeds, without considering the survival rate after transplanting and transplanting
[0007] Chinese patent CN109122073A discloses a planting method of medicinal cattails, including the steps of soil preparation, transplanting and planting, weeding, irrigation, and fertilization. The patent realizes the shortening of cattail seedlings by fertilizing and topdressing the cattail seedlings during the planting process. During the harvest period, the effect of increasing the output of cattail per unit planting area, but this method does not disclose how to obtain medicinal cattail seedlings that can be planted in batches

Embodiment 1

[0039] Embodiment 1 cattail seed collection

[0040] The flowering period of cattails is from mid-to-late May to early-to-mid June. We select wild cattails with uniform growth in the fish pond, half of which are harvested and half of which are not harvested. Collect cattail seeds in July, August, September, October, November, next April, and next May. After harvesting the seeds, store them in a dry, cool, and well-ventilated warehouse.

[0041] In May of the second year, after soaking for about 14 hours, 200 seeds were evenly taken, and the indoor parallel array was placed on the soil surface premixed with chicken manure and soil mass ratio of about 2:1 to simulate planting, and the germination rate was measured by spraying water regularly for 20 days. .

[0042] The evaluation results are as follows:

[0044] harvest month The weight of 10 cattail sticks (g) Germination rate(%) ...

Embodiment 2

[0046] Embodiment 2 pretreatment

[0047] In mid-May, soak the cattail seeds with sticks in cold water at room temperature for pretreatment. After drying in the shade, take 200 seeds in parallel arrays indoors and place them in chicken manure. The soil mass ratio is about 2:1. Spray water for 20 days, observe seed germination time and germination rate, the results are as follows:

[0048] Table 2 Germination time and germination rate of Puhuang seeds with different soaking times

[0049] Soaking time Germination time (days) Germination rate(%) do not soak 7-20 56％ 2 hours 7-20 60％ 6 hours 6-15 76％ 10 hours 7-12 93％ 14 hours 7-11 96％ 18 hours 6-10 91％ 24 hours 6-9 74％

[0050] From the above data, it can be known that soaking time can affect the germination time and germination rate. Specifically, seeds that are not soaked or soaked for a short time have a longer germination time and a lower seed germination r...

Embodiment 3

[0051] Embodiment 3 base fertilizer type screening

[0052] 1. Harvest cattail sticks and save seeds in late October;

[0053] 2. Soak cattail sticks in clean water for about 14 hours at room temperature in mid-May and then dry them in the shade;

[0054] 3. Select the land with a soil layer thickness of 60±5cm, and divide it into untreated chicken manure, sheep manure, cow manure, horse manure and fermented and decomposed synthetic farmyard manure, respectively according to 550kg / 776m 2 The dosage is premixed with the soil at a ratio of 2:1 and spread evenly, and the pretreated seeds are mixed with 40ml / m 2 (sparse), 70ml / m 2 (moderate), 100ml / m 2 (Dense) Three seeding densities are planted, and the covering soil is 0.5±0.2cm;

[0055] 4. Use a fixed amount of sprinkler irrigation to control the soil humidity to 30±5%, and measure the height of cattail seedlings in the first ten days of November of the same year.

Abstract

The invention relates to a seedling raising method for medicinal typha orientalis, which comprises the steps of seed selection, land selection, fertilization, seed soaking, sowing, irrigation and the like, and realizes artificial cultivation of typha orientalis seedlings by regulating and controlling the fertilization and irrigation steps, so that the yield of the typha orientalis seedlings is improved, and the problem that the number of wild typha orientalis seedlings is limited is solved; the method is easy to operate, meets the requirement for large-area planting, achieves nearby planting and has good technical popularization prospects.

Description

technical field [0001] The invention belongs to the field of plant planting, in particular, the invention relates to a method for cultivating medicinal cattail seedlings from seeds. Background technique [0002] Typha angustifolia (scientific name: Typha angustifolia L.) is a perennial aquatic or marsh herb, also known as cattail, cattail or water candle, belonging to the genus Typhaceae. Cattails are mostly born in lakes, ponds, ditches, swamps and slow-flowing rivers. They are distributed in Heilongjiang, Jilin, Inner Mongolia, Hebei, Jiangsu, Zhejiang, Jiangxi, Guangdong, Yunnan and other provinces in China. They have the function of purifying and improving water quality. , cattail has high economic value, and the dry pollen of cattail is used as medicine; the leaves can be used for weaving, papermaking, etc.; the base of young leaves and the apex of rhizome can be used as vegetable food; the female inflorescence can be used as filling for pillows and cushions, which is a...
