Embodiment 1

[0033] The cultivation of a kind of potato tissue culture seedling of embodiment 1

[0034] (1) Cultivation of shoot tip seedlings

[0035] Choose healthy potatoes, treat the terminal buds or side buds together with some petioles and stems in 70% alcohol for 30s, then soak in 10% bleach solution for 5-10min, and then rinse with sterile water two or three times;

[0036] After disinfection, put it under a binocular dissecting microscope of 10-40 times to peel off, press the stem bud with tweezers in one hand, and peel off the young leaves and large leaf primordia with a dissecting needle in the other hand until the round and bright growth points are exposed. Use a scalpel to cut off the small shoot tip with one or two leaf primordia, and quickly inoculate it on the shoot tip seedling medium for cultivation. The cultivation temperature is (25±2)°C, and the light intensity is 1000 lx for the first 4 weeks, and increases after 4 weeks. To 2000-3000lx, 16h of light per day, grow i...

Embodiment 2

[0045] Embodiment 2 A kind of transplanting seedbed for producing the original seed of potato

[0046] (1) Seedbed preparation

[0047] The transplanting seedbed is divided into three layers: the bottom layer is 8 cm thick nutrient soil, the middle layer is 1 cm thick solid medium particles, and the upper layer is 3 cm thick vermiculite;

[0048] After the nutrient soil is laid, every 667m 2 Treat the soil with 50% phoxim EC 250ml, 72% agricultural streptomycin SPX 250ml, 50% carbendazim WP 250g, and then carry out rotary tillage, suppression and leveling;

[0049]Lay a 40-mesh nylon sieve on the leveled soil, and then lay solid medium particles on the sieve;

[0050] Lay 20-mesh nylon screen on the solid medium particles, and then spread vermiculite on the screen, every 667m 2 Apply 10kg of nitrogen, phosphorus, and potassium compound fertilizers to the vermiculite, and stir well to mix evenly;

[0051] (2) Nutrient soil

[0052] Nutrient soil consists of 60 parts of soi...

Embodiment 3

[0067] Embodiment 3 A kind of transplanting seedbed for producing the original seed of potato

[0068] (1) Seedbed preparation

[0069] The transplanting seedbed is divided into three layers: the bottom layer is 12cm thick nutrient soil, the middle layer is 2cm thick solid medium particles, and the upper layer is 5cm thick vermiculite;

[0070] After the nutrient soil is laid, every 667m 2 Treat the soil with 50% phoxim EC 250ml, 72% agricultural streptomycin SPX 250ml, 75% chlorothalonil WP 250g, and then carry out rotary tillage, suppression and leveling;

Abstract

The invention belongs to the technical field of potato breeding, and particularly relates to a preparation method of a transplanting seedbed. The transplanting seedbed is divided into three layers, the bottom layer is nutrient soil, the middle layer is solid culture medium particles, and the upper layer is vermiculite; the nutrient soil is composed of a soil part and an organic fertilizer, the organic fertilizer is fertilizer with an insecticidal effect, harmless treatment of a culture medium is achieved through preparation, and the problem of environmental pollution caused by aftertreatment is reduced; and meanwhile, the use amount of insecticide can be saved by 25-35%, phytotoxicity and drug resistance of crop are avoided, and the risk of pesticide residue is also reduced.

Description

[0001] This application is a divisional application of Chinese invention patent application 201710938441X. The filing date of the original application is September 30, 2017. The title of the invention is: a transplanting seedbed with insecticidal effect. Technical field: [0002] The invention belongs to the technical field of potato breeding, and in particular relates to a method for preparing a transplanting seedbed with insecticidal effect. Background technique: [0003] The original potato seed is the preferred potato seed for modern potato planting. It selects high-quality potato seed potatoes, detoxifies the stem tip, and starts tissue culture and rapid propagation after virus detection. After 10-15 days, the tall and strong potato seedlings with a length of 10-15 cm are cut and obtained for colonization. At present, most of the virus-free seedling cuttings are cultivated on a special substrate in the greenhouse to obtain the original seed. Because the virus-free seed...
