Raising method for blumea balsamifera seedlings

Abstract

The invention discloses a raising method for blumea balsamifera seedlings. The raising method comprises the following steps: selecting seed collecting stock plants; spraying mixed solution of monopotassium phosphate and gibberellin to the seed collecting stock plants at the bud period; collecting seeds for later use after the seeds become mature; preparing land, sterilizing and preparing seed beds; heating a seedling raising substrate at the temperature of 180-200 DEG C for 20-40 minutes and laying the seedling raising substrate in the seed beds; soaking the seeds by using gibberellin missible oil with weight percentage concentration of 4 percent at an amount which is 600 times the amount of the seeds for 24 hours at the day before sowing; sowing by using a water blending method; laying a thin film shed outside the seed beds after sowing; transferring seedlings into nutrition bags to culture until the seedlings grow to 15-20 cm after the seedlings emerge; and out-planting the seedlings after expansion of 7-8 true leaves. According to the raising method, the maturity of the seeds can be improved, the germination rate is enhanced, the seedling raising substrate has no weeds, insects or disease sources, the seeds are sown evenly and can be effectively prevented from being washed away by rain, the seedlings are effectively prevented from being turned over by rain, and light, temperature, water and heat conditions are provided for seed germination and seedling growth, so that the emergence rate is high, and the seedling growth is quick.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for growing seedlings of Aina japonica. Background technique [0002] Ainaxiang is a perennial woody herbaceous plant in the genus Blumea of ​​the Asteriaceae family. Alias: borneol leaf, borneol moxa, earth borneol, wormwood, mountain moxa, big wind moxa, cow's ear moxa, Zaifeng moi, big bone wind, rhubarb grass, true gold grass, Ye Xiaxiang. Mainly produced in China and Southeast Asian countries. Distributed at 21 north latitude in my country o 30′~25 o 50′, 97 E o 30′~121 o In Guizhou, Guangxi, Guangdong, Yunnan, Fujian, Hainan and Taiwan provinces at 55′, the vertical distribution is below 1000m, and the artificial cultivation is mainly below 800m. Guizhou has a cultivation history of hundreds of years. The stems and leaves of Ainaxiang contain flavonoid glycosides, three essences, amino acids, organic acids, and volatile oils such as L. borneol, 1.8. euc...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for growing seedlings of Aina japonica, which solves the problem that the seeds in the Aina japonica seedlings do not emerge or the emergence rate is extremely low, and it is difficult to sow with pappus, and the sowing is uneven and the seed grains are extremely small. Watering and raining after sowing are easy to wash away the seeds and overturn the seedlings. It is difficult to separate the seedlings and grasses at the seedling stage, and it is easy to damage the seedlings when weeding.
