Description
Technical Field
The invention relates to the technical field of agriculture, in particular to a method for shortening a dormancy period of paris polyphylla seeds and a seedling growing method.
Background
The paris polyphylla is a traditional national medicine, is recorded in Shen nong Ben Cao Jing by the name of 'pariphyllin', and is a dry rhizome of Yunnan paris polyphylla or paris polyphylla of liliaceae by taking paris polyphylla as a formal medicine name by the national medical book 'Yunnan Ben Cao'; it is bitter in taste and slightly cold in nature; has little toxicity; has the efficacies of clearing away heat and toxic material, relieving swelling and pain, and cooling liver and arresting convulsion, and is commonly used for treating furuncle and carbuncle, swollen and sore throat, snake and insect bite, traumatic injury and convulsion.
The method for rapidly developing the planting of the paris polyphylla needs a large amount of high-quality seedlings, and the paris polyphylla seedlings are mainly bred in two modes of underground stem breeding and seed sowing and seedling breeding. The Paris polyphylla resources are less, the underground stem cutting propagation mode is long, and the propagation coefficient is low; the conventional seeds are sowed and grown, the seedlings can emerge and grow continuously only in 1-2 winter, the seedling emergence period is long and irregular, the seedling emergence rate is low, the yield of the paris polyphylla seeds is very low, and the difficulty of sowing and growing the seedlings by the conventional seeds is a main reason for the shortage of the paris polyphylla seedlings. Aiming at the defects, a method for cultivating the seedlings of the paris polyphylla is necessary.

In the step 1), the seeds are mixed with soil with 35% -45% of water content according to the proportion of 1:2, and then refrigerated.
The invention adopts a special refrigeration and normal temperature alternate treatment mode, wherein the once refrigeration and normal temperature treatment are equivalent to the situation that the seeds are subjected to a dormancy period, the dormancy period can be quickly passed by the seeds in a short time through a manual mode, the memory of the paris polyphylla seeds can be advanced by two dormancy seasons, and the dormancy period of the seeds is greatly shortened, so that the germination and emergence periods of the seeds are shortened.
A seedling raising method of Paris polyphylla seeds comprises the following steps of 1) collecting mature Paris polyphylla seeds, removing the seed skins of the Paris polyphylla seeds, and naturally drying the Paris polyphylla seeds in the shade at the temperature of 10-15 ℃ for 10-15 d; 2) treating the seeds in a refrigeration and normal temperature alternative mode; 3) soaking the seeds in boiled boiling water for 6-10s, taking out, and rapidly soaking in cold water; 4) taking out the seeds, soaking the seeds in 800 times of carbendazim 500-fold liquid for 2-3h, taking out and airing; 4) sowing the seeds on a seedling bed, covering a seedling substrate, and watering thoroughly.
And 4) mixing the seedling culture substrates of the seeds according to the mass ratio of 6:2:9 of humus, organic fertilizer and loam.
The cold water is ice blocks and water according to the mass ratio of 1: 50, and mixing.
The seeding rate of the seeds in the step 4) is 580-620 grains per square.
The seedling method adopts a cold storage and normal temperature alternate mode plus boiling water and rapid cooling treatment mode for seeds, the cold storage and the normal temperature alternate mode can shorten the dormancy period of the seeds, the seeds are treated by the boiling water, mainly, the skins of the white seeds of the paris polyphylla seeds have things like a layer of film, the soil moisture is difficult to enter after direct sowing, the seeds are cooled immediately after the boiling water treatment, and the film can crack through the principle of expansion with heat and contraction with cold, so that the seeds can be rapidly received by soil to rapidly fuse with each other in the field to sprout more rapidly, the sprouting time of the seeds can be greatly shortened, and the emergence rate of the seeds can be improved; wherein the germination time is usually 120-140 days, the germination time is 140-180 days, and the germination rate is as high as 80-85%.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the seedling raising method of the paris polyphylla seeds adopts a special refrigeration and normal temperature alternate treatment mode, wherein one refrigeration and normal temperature treatment are equivalent to a situation that the seeds are subjected to a dormancy period, the dormancy period is quickly passed by the seeds in a short time in a manual mode, the memory of the paris polyphylla seeds can be advanced by two dormancy seasons, and the dormancy period of the seeds is greatly shortened;
2. according to the seedling raising method for the paris polyphylla seeds, the seeds are treated by boiling water and then are cooled immediately, and the thin film on the surfaces of the seeds can be broken by the principle of expansion with heat and contraction with cold, so that the seeds can be quickly fused with the ground to quickly receive water to bud, the germination time of the seeds can be greatly shortened, and the germination rate of the seeds can be improved.
