The latest course on planting techniques and methods of tomatoes after autumn

Tomato cultivation almost does not bear fruit in autumn, but if you want to continue to cultivate tomato in autumn, the external environment is not suitable, you can protect the cultivation, but the way of cultivation is delayed cultivation in autumn. In some areas, the lateral buds of tomato were directly cut and cultivated in some areas, and the effect was better. Next, let's learn about the specific cultivation methods of autumn postponement.

1. Seedling raising time

Using cuttage to raise seedlings can shorten the time of raising seedlings and strive not to be affected too much by the external climate. Cuttings can start in June, when raising seedlings, the temperature is more suitable, the growth is very fast. But not too early, encounter high temperature, seedlings prone to disease, low survival rate of colonization, easy to die seedlings. But it's too late to raise seedlings. The cultivation time is easy to encounter frost, and the fruit is difficult to ripen. If transferred to a protected area, it will also be affected by the outside world.

2. Seedling raising method

The film on both sides of the seedling shed is rolled up and surrounded by a membrane around it to facilitate ventilation and receive light. Set up an anti-insect net, build a ceiling film and a sunshade net, and open a good drainage ditch around. Take robust buds at the base, lateral buds, with a few leaves. Cut off the lower part, soak in a 500-fold solution of 25% carbendazim wettable powder for a few minutes, dry and dip in rooting powder for cutting. Use a clean seedling tray, install a sterilized culture medium, and insert the buds into the substrate for two centimeters. Spray through the water and put it on the seedbed to build a small arch shed.

3. Seedling management

Cuttings can not open the film within five days, maintain a temperature of 30 degrees, 305 degrees need to cover the sunshade net. The sun comes out in the morning and uncovers when the sun sets, but it doesn't cover on cloudy and rainy days. Then spray water in the morning and evening, spray 0.3% urea solution, spray 0.2% potassium dihydrogen phosphate solution at intervals of two days, and then spray urea at intervals of several days. Apply hydrolytic fertilizer at intervals of one week.

4. Planting method

Generally, it can be planted within a month, and the ear of flowers should be removed a few days before planting. In this way, it maintains vegetative growth and promotes growth and germination. Colonization is carried out in cloudy days to help slow down seedlings, reduce evaporation and improve the survival rate. Slow seedling after watering, fertilization, promote growth, slow seedling period, to refine seedlings to help later growth. The planting row spacing is 20 cm, and the plant spacing is 10 cm.

The method of raising seedlings with lateral buds of tomatoes after autumn is more efficient. The main purpose is to raise seedlings, and then the continuous management after planting.
