Tomato (tomato) planting method

Tomato is a kind of vegetable with high nutritional value, which is rich in vitamin C. it has antioxidant and whitening effects, and is deeply loved by the public. So, what is the method of growing tomatoes? The following editor will introduce you one by one.

I. seed selection

Select varieties with high budding rate and cold tolerance. The germination rate of seeds should be tested before selecting seeds. The higher the germination rate is, the fuller and more uniform the seeds are, the greater the harvest will be and the better the economic benefit will be. The germination rate of good seeds should be higher than 90%. In addition, it is also necessary to test the cold tolerance of seeds. The temperature in the south of our country is higher than that in the north, and the seeds have high sensitivity to cold, so we should choose cold-resistant seeds.

2. Sowing and planting

The suitable time for sowing is from mid-late August to early September. After accelerating germination, the seeds were buried in the border with nutritious soil, and the suitable temperature of the seedling bed was 25-30 degrees. After emergence, the suitable temperature is 25-30 degrees in daytime and 15-20 degrees at night. During the period of germination of true leaves of seedlings, attention should be paid to the control of temperature difference between day and night. Pay attention to ventilation a week before planting.

Tomato has a long growth cycle and needs a large amount of fertilizer, so it is necessary to apply sufficient base fertilizer before planting. The following is the recommended amount of fertilizer: per 667m2, 2000 kg of rotten farm manure, 100kg of ternary compound fertilizer and 100kg of bean cake.

Plant on a sunny day, select healthy, strong plants for planting, and maintain a distance of about 45 centimeters. Watering and loosening the soil after planting.

III. Fertilizer and water management

Do not water the seedlings when squatting, because it is necessary to ensure that the roots are tied down. Before the first ear of tomato is settled, it mainly grows at the initial stage, and basically does not need watering and fertilization in the rest of the time.

Tomato has a great demand for nitrogen and potassium fertilizer, as well as an appropriate amount of phosphate fertilizer. When the fruit of the first ear is settled, 20-30kg potassium sulfate compound fertilizer can be applied per 667m2. When the fruit of the second ear and the third ear expands rapidly, topdressing fertilizer can be applied for about 3 times.

IV. Pest control

The common diseases and insect pests of tomato are early blight, gray mold, stem rot, aphids and ladybugs.

1. Early blight

Early blight generally starts from the lower leaves and gradually spreads upwards. in severe cases, all the leaves die, causing great harm to leaves and fruits.

In the event of an early epidemic, the following measures may be taken:

① and non-Solanaceae crop rotation and stubble every 3-5 years

Selection of disease-resistant varieties in ② seed selection

③ soaked the seeds in hot water about 60 degrees for half an hour, took them out, soaked them in lime water, washed them, and then sowed them.

2. Grey mold

Botrytis cinerea generally occurs in an environment of low temperature and high humidity, and watering should be avoided as far as possible. After the disease, you should pick the diseased fruit and leaves in time.

The occurrence of Botrytis cinerea should be dipped in the flower medicine during flowering, 50% carbendazim wettable powder should be applied in the first ear tomato fruit flowering, and the third application should be prevented with 85% carbendazim wettable powder 800 times the day before the fruit water is poured.

3. Stem rot

The control of stem rot can be carried out through fertilization, nitrogen fertilizer should be appropriate, at the same time, apply nitrate nitrogen such as sodium nitrate on diseased plants, and be careful not to apply ammonium nitrogen. After applying fertilizer twice, 0.2% glucose and 0.1% potassium citrate mixture can be sprayed to increase the content of sugar and potassium in the leaves.

4. Aphids and ladybugs

When these two kinds of insect pests occur, 2500 times of 50% aphid pine oil or 2000 times of 20% butyl EC can be used for prevention and control.
