Embodiment 1

[0056] Present embodiment is the laboratory production of potato test-tube seedling:

[0057] (1) Make a polypropylene film bag: cut the polypropylene film into a rectangle of 35cm×10cm, fold two 2.5cm wide from 15cm, and glue the two sides together with a plastic sealing machine to make it 15cm high and 10cm wide open pocket.

[0058] (2) Preparation and distribution of culture medium:

[0059] The culture medium was prepared as follows:

[0060] ① Accurately weigh KH 2 PO 4 170mg, NH 4 NO 3 1650mg, KNO 3 1900mg, CaCl 2 2H 2 O 440mg and MgSO 4 ·7H 2 O 370mg, placed in 200ml beakers respectively, after adding 100ml of purified water to dissolve respectively, mix the solutions in 2000ml beakers according to the order of the listed medicines, pay attention to mixing slowly, keep stirring, and set aside;

[0061] ② Accurately weigh MnSO 4 4H 2 O 22.3 mg, ZnSO 4 ·7H 2 O 8.6 mg, H 3 BO 3 6.2 mg, KI 0.83 mg, Na 2 MoO 4 2H 2 O 0.25 mg, CoCl 2 ·6H 2 O 0.025 m...

Embodiment 2

[0068] This embodiment is the rapid propagation of sugar-free cultivation in the test-tube seedling greenhouse:

[0069] (1) Soak the test-tube seedlings in the plant growth regulator solution for 20 minutes, take it out, and the plant growth regulator solution contains 25 mg of NAA, 25 mg of IBA and 40 mg of IAA in 1 liter of water. The test-tube seedlings at this time are cutting seedlings with 1 to 2 stem sections with axillary buds. Prepare a 50-hole plug tray with a cultivation substrate, insert the cutting seedlings into the plug holes of the plug tray, and water until the water is wet after cutting. It flows out from the hole at the bottom of the plug; the cultivation substrate formula is sand: vermiculite: perlite = 2:2:1.

[0070] (2) Put the completed trays into the water tank for liquid culture. There is nutrient solution I in the water tank, keep the depth of the nutrient solution at about 0.3cm, and cover the surface of the trays with plastic film for cultivation....

Embodiment 3

[0080] This embodiment is the original original seed produced by substrate+liquid culture:

[0081] (1) When the cutting seedlings grow in the 4th week, replace the nutrient solution in the water tank with nutrient solution II, keep the depth at 1-2 cm, and place a hard plastic tube with a diameter of about 1 cm under the hole plate so that the bottom of the hole plate does not touch bottom of the sink, the process lasts 2 weeks;

[0082]Among them, the formula and preparation method of each liter of nutrient solution II are as follows:

[0083] ① Accurately weigh MnSO 4 4H 2 O 4.46 mg, ZnSO 4 ·7H 2 O 1.72 mg, H 3 BO 3 1.24 mg, KI 0.17 mg, Na 2 MoO 4 2H 2 O 0.05 mg, CoCl 2 ·6H 2 O 0.005 mg, CuSO 4 ·5H 2 O 0.005 mg, FeSO 4 ·7H 2 O 5.56 mg, Na 2 — EDTA 7.46 mg in a 200ml beaker, add water to dissolve, slowly pour into a 2000ml beaker, stir and mix well, and set aside;

[0084] ② Accurately weigh N:P 2 o 5 :K 2 O=19:19:19 Put 1g of compound fertilizer in a be...

Abstract

The invention discloses a method for producing pre-basic seeds of potatoes. The method comprises the steps as follows: laboratory production of potato tube seedlings, sugar-free culture and fast propagation in a tube seedling greenhouse, and matrix and liquid culture for producing pre-basic seeds of potatoes. According to the invention, a polypropylene film bag takes the place of a traditional glass container, so that the light transmission and the air permeability are good, the cost is low, the weight is light, and the carrying is simpler; the mode of matrix and liquid culture achieves the purpose of propagating pre-basic seeds in a layered manner, so that not only can vain growth of the overground parts be controlled effectively, and growth and development of creeping stems of plants are ensured, but also forming and expanding of tubers at the top ends can be promoted effectively, and the operation is simple and easy; the pre-basic seeds can be grown in a plurality of seasons in a year, the quantity of potatoes borne in a unit area and the yield are improved greatly, the cost is reduced considerably, the propagation efficiency is improved, and industrial and mass production of virus-free miniature seed potato of potatoes can be realized.

Description

technical field [0001] The invention relates to a method for producing original potato seeds, belonging to the field of agricultural cultivation. Background technique [0002] Potato is not only one of the main food crops in my country, but also an important feed and industrial raw material crop, with high economic benefits. However, due to the degradation of potato varieties and serious diseases, the development of potato industry is limited. In recent years, by cultivating virus-free seed potatoes and establishing a breeding system for improved varieties, a key problem restricting the development of the potato industry has been effectively solved. Virus-free seed potatoes are cultivated by peeling off the 0.3mm shoot tip of potato plants to form regenerated plants. After virus serological detection, the non-toxic plants are subjected to tissue culture and rapid propagation to produce test-tube seedlings. Under the conditions of isolated production in greenhouses and net ...
