Do you like to eat konjac? Our common konjac is actually made from a large black head. There are many areas in the countryside where konjac is planted. So how to plant and manage? Let's take a look at the konjac planting techniques.
I. Facilities requirements and conditions
Planting seedlings must have certain isolation conditions.
1. The air humidity is around 80%-90%;
2. The light saturation point is 17000-22000L x and the light compensation point is 2000 L x ;
3, the soil layer is deep, rich in organic matter, good ventilation, the soil does not carry germs;
4. The optimum temperature for the growing season is around 25 °C.
Second, the technical requirements before transplanting
1, take care of. Ditching, the face width is 120cm, and the loose soil layer is 30cm.
2. Soil disinfection. 50 kilograms of quicklime per acre is applied to the noodles, then deep-turned; spray 60 kilograms of 40% formaldehyde 300 times per acre, cover the plastic film, close the greenhouse, smouldering for 10-15 days, then uncover the film Ventilate for more than 7-10 days.
3. Fertilization. A small amount of fully decomposed farmyard manure and organic fertilizer can be applied and deeply mixed into the soil.
4, watering. The surface layer of the buckwheat soil was irrigated 1 day before transplanting.
Third, tissue culture seedling transplanting
1. After the tissue culture seedlings are bottled, the root culture medium is washed, and then immersed in 50% carbendazim 500 times solution for 5-8 minutes for disinfection treatment.
2, the planting seedling plant spacing is 15 × 15 cm.
3. After the set value of the tissue culture seedlings is set, the root water should be poured, and then according to the soil moisture, it is determined whether the water is kept, and the soil moisture is kept at 50%-60%.
4, after transplanting the tissue culture seedlings, build a small arch shed on the surface of the glutinous rice, the conditions of moisturizing and heat preservation can increase the survival rate of the tissue culture seedlings. The temperature is controlled at 13 °C -30 °C and the humidity is maintained at 80%-90%.
5. After transplanting the tissue culture seedlings, always check the temperature and humidity in the small arch shed. If the temperature or humidity is too high, the small arch shed should be uncovered to reduce the temperature and humidity, and prevent the tissue culture seedlings from burning and rot.
6. After the tissue culture seedlings survive, spray the amino acid foliar fertilizer 2-3 times and the bio-organic fertilizer 1-2 times before the konjac maturity period.
7. The common pests and diseases of konjac planting include the pheasant chafer. After the adult worm, the pheasant will also eat the bulbs and rhizomes of the konjac plant, causing soft rot to occur, and the damage is very large. If you find this insect in the soil, you can use the Koline 360 ​​° virus nemesis to kill insects.
8. Immediately remove the weeds after transplanting the tissue culture seedlings. Care should be taken to prevent damage to seedlings when pulling grass.
9. When the tissue culture seedlings are harvested, an average of 50-60 grams of seedlings can be obtained, and the maximum can reach about 200 grams, and the cockroaches are 2-3. The disease-free and detoxified konjac tissue culture seedlings have 3-11 leaves, and one konjac can get 2-5 species at the same time.
