Embodiment 1

[0012] Embodiment 1 is to adopt the seedling raising method of the field seedling bed of prior art as contrast, and concrete steps are as follows:

[0013] 1. Preparation before sowing

[0014] (1) Cultivated land preparation: 20 days before sowing, plow the land, remove sundries, and sterilize in the sun. At the same time, combined with deep plowing, you can apply pollution-free, high-efficiency, low-toxic sterilization and insecticides. Specifically: fungicide carbendazim 50% wettable powder 10g / m 2 , Insecticide Dichroa (10% diazinon granules) 500g / 667m 2 .

[0015] (2) Make a furrow: Dig and finish 5 days before planting, use a hoe to deeply dig the soil 20cm to 25cm, break up the soil clods, rake and level the furrow with a width of 1.2m and a height of 20cm, and the length depends on the field. Manure according to 4000kg / 667m 2 Sprinkle evenly on the border surface, mix evenly, the depth of the mixing is 10cm ~ 15cm, standardize and level the border surface, then flo...

Embodiment 2

[0032] Embodiment 2 uses the embodiment of the method of the present invention.

[0033] Except that the following methods are different, the rest of the methods are the same as in Example 1 and will not be repeated here.

[0034] Grow the golden iron lock seeds in the greenhouse, and keep the soil temperature in the greenhouse at 20°C±2°C during the seedling cultivation period. If the temperature is too high during the day, timely ventilation and shading should be carried out to cool down. If the temperature is too low, try to seal the greenhouse to keep warm; Inner seedbed spray irrigation measures control the soil moisture in the shed, and control the soil moisture at 50% to 54% after the seeds are sown until there are 2 pairs of true leaves. After the golden iron lock seedlings grow to have 2 pairs of true leaves to 3 pairs of true leaves, the soil humidity is controlled at 28% to 31%. After the golden iron lock seedlings grow to have 3 pairs of true leaves until the seed...

Embodiment 3

[0035] Embodiment 3 and embodiment 4 are also embodiments of the method of the present invention, except that the specific measures listed in Table 1 are different, and all the other specific measures are the same as in embodiment 2, so no further details are given. Embodiment 3 and embodiment 4 compare with the effect of contrast, see table 2 for details.

[0036] Different measures of table 1 embodiment 2, 3 and 4

[0037]

[0038] Table 2 The inventive method compares with the effect of contrast

[0039]

[0040]The above examples show that it is difficult to control the soil temperature and humidity during the stage of sowing to seed emergence in open-air seedling cultivation, and the time and frequency of watering every day are increased compared with those in greenhouses, but the evaporation is large and the soil is covered. Because the soil is thin, it is difficult to maintain the soil humidity at About 50%, directly affects the emergence rate. In the rainy seas...

Abstract

The invention discloses a greenhouse seedling raising method of a Psammosilene tunicoides seed, belonging to the technical field of raising the seedling of a plant seed. The method comprises the following steps: raising the seedling of a Psammosilene tunicoides seed in a greenhouse, maintaining the soil temperature at 20+ / -2 DEG C in the greenhouse, controlling the soil humidity at 50-65% in the greenhouse in a period from the sowing of the Psammosilene tunicoides seed to the growth of two pairs of euphyllas, controlling the soil humidity at 28-38% in the greenhouse in the growing process of the Psammosilene tunicoides seedling from the growth of two pairs of the euphyllas to the growth of three pairs of the euphyllas, and controlling the soil humidity at 15-30% in the greenhouse in the growing process of the Psammosilene tunicoides seedling from the growth of three pairs of the euphyllas to the outplanting of the seedling. By artificially regulating the soil temperature and the appropriate soil humidity for different growth stages of the Psammosilene tunicoides seed based on seedling raising in the greenhouse, the method effectively lowers the morbidity at the seedling stage, improves the germination rate and the survival rate, and raises the strong seedling; and compared with a control sample, the germination rate is improved by 23-26%, the survival rate is improved 12-32%, and the average individual weight is improved by 0.8-1.2g.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation of plants, and in particular relates to a method for raising seedlings of golden iron lock seeds. Background technique [0002] Psammosilene tunicoides (Psammosilene tunicoides W.C.Wu et C.Y.Wu), also known as Du Stinger, Centipede Seven, Kunming Aphrodisiac, Psammosilene tunicoides W.C.Wu et C.Y.Wu, etc., is a plant of the genus Psammosilene tunicoides. Jin Tiesuo is a unique single-genus plant in Southwest my country, and it is a national second-class protected plant. Jintiesuo is also a famous folk medicinal plant in Yunnan Province and one of the important ingredients of Yunnan Baiyao. Traditional medicine proves: Jin Tiesuo has the effects of removing rheumatism, analgesia, hemostasis, and blood stasis, and is often used to treat rheumatic arthralgia, stomach pain, traumatic bleeding, and bruises (Jiangsu New Medical College. Chinese Medicine Dictionary (Volume 1) [M]. Shanghai ...
