Embodiment 1
[0024] Embodiment 1 rapid seedling cultivation of rhubarb of the present invention
[0025] 1. Construction of nursery ponds and sheds
[0026] 1. Site selection
[0027] The selected site should be open and flat, without tall trees or buildings, with convenient transportation, sufficient water and electricity, convenient irrigation and drainage, no water quality and air pollution around, sheltered from the wind and facing the sun. The altitude of the site can range from 500m to 1500m at medium and low altitudes, or 1500m to 3500m at high altitudes.
[0028] 2. Construction of nursery ponds (nursery pots)
[0029] Fully floating seedlings: the length and width of the nutrient pool are adjusted according to the specifications of the seedling tray and the scale of the seedlings. The length, width, and height of the standard nutrient pool are 560cm*140cm*20cm. The bottom of the pool is flat, the level difference is not more than 1.5cm, the four corners are vertical, and the po...
Embodiment 2
[0080] The matrix screening experiment of embodiment 2 rhubarb rapid seedling raising of the present invention
[0081] Except that the substrates in Section 1.2 of Step 3 are respectively the substrates in the following Table 1, the rest of the conditions are the same as in Example 1, and rhubarb seedlings are cultivated to calculate the emergence rate.
[0082] The germination rate is shown in Table 1 below:
[0083] Table 1 Effects of different substrates on the emergence of rhubarb
[0084]
[0085] As shown in Table 1, the mixture of peat and perlite with a weight ratio of (5-7): (3-5) is used as the substrate, and rhubarb is cultivated under the specific conditions of the present invention, the emergence rate is high, the emergence is neat, and the plants grow well. , which is significantly better than other commonly used substrates. Among them, when the weight ratio of peat and perlite is 7:3, the effect is the best, and the emergence rate is as high as 95%.

Abstract
The invention discloses a rapid rhubarb seedling growing method. The rapid rhubarb seedling growing method includes the following steps: 1), building a seedling growing pool or picking a seedling growing basin and adding water; 2), picking and sterilizing a seedling growing plate, placing a seedling growing base material into the seedling growing plate, and sowing pre-treated rhubarb seeds into the seedling growing plate to acquire the seedling growing plate subjected to sowing, wherein the seedling growing base material comprises, by weight, 50-70% of peat and 30-50% of perlite; 3), placing the seedling growing plate subjected to sowing in the step 2) into the seedling growing pool or seedling growing basin in the step 1) for cultivation, and after seedling emergence, adding fertilizer into water in the seedling growing pool or seedling growing basin once every ten days until nitrogen concentration is 150-250g / L, phosphorus concentration is 10-40g / L and potassium concentration is 200-300g / L; 4), completing cultivation after the diameters of rootstocks of rhubarb seedlings are not less than 1cm and roots and the rootstocks are 5-10cm in length. The rapid rhubarb seedling growing method is simple and convenient to operate, high in seeding emergence rate, short in time, low in cost and good in economic benefit, and the rhubarb seedlings grown by the method grow rapidly, orderly and healthily.
Description
technical field [0001] The invention relates to the field of cultivation, in particular to a method for rapidly growing rhubarb seedlings. Background technique [0002] Rhubarb is the collective name of Rheum palmatum L., Rheum tanguticum Maxim.ex Balf., Rheum officinale Baill., a perennial tall herb of the Polygonaceae Rhubarb genus. The stem is used as medicine. The medicinal material rhubarb (Radix et Rhizoma Rhei) mainly contains anthraquinone glycosides and free anthraquinone derivatives. It is bitter in taste and cold in nature. Indications for constipation due to excessive heat, stagnant abdominal pain, unpleasant diarrhea, damp-heat jaundice and other diseases. At present, rhubarb is widely used in medicine and pharmaceutical chemical industry. It is recognized as a best-selling variety in the top ten medicinal material markets in the country, and it is also a well-known traditional export medicinal material in my country. Rhubarb likes cool and cold climates, is ...
