1. Seed selection and processing
When we choose seeds, we should choose all kinds of disease-resistant and high-yield ones. Several varieties were selected in North China, such as Jin Peng/KOOC-0/0, Xinong 20/KOOC-0//KOOC-0/,Jin Peng M6088, Yali 6/KOOC-0/6 and Fen 802. And then the seeds are treated. First of all, we should celebrate, put the seeds in the sun for two or three days, and then use them 500 times to release 50% of the bacteria. Pick it up in five hours, pick it up and put it away for half an hour until it reaches 10% trisodium phosphate solution, then clean it, put it into germination, put it into gauze, cover it with a wet towel, and then put it in an environment of 25 degrees. Be careful, put the towel in a wet state and spray it with warm water for a day or two or twice until the seeds are nearly 70% to 80%.
2. Then plant seeds
When sowing, you must choose big prince strain, which can be listed during the Spring Festival. It's better this time, so adjust measures to local conditions. Generally speaking, it will be chosen in mid-August or early September. Then, prepare the seedbed. Nutrient soil is put into a container of 8 cm× 8 cm, then placed in 1.2×6 m, and then the seedbed is managed until the seedlings are properly ventilated. The daytime temperature should be controlled between 25 and 30 degrees. The temperature at night should be controlled between 15 and 20 degrees. In the process of management, we should pay attention to the prevention and control of pests and diseases, and wait until the tomato seedlings grow to seven or eight leaves. It can be transplanted.
plant
First of all, base fertilizer should be put, because its growth process is relatively long, so the requirements for fertilizer will be higher. We can use 2000 pounds of compound fertilizer and 200 pounds of pesa, 200 pounds of compound fertilizer and 200 pounds of boron fertilizer, zinc fertilizer and magnetic fertilizer simultaneously. Fertilization can be used during fertilization, and then the course can be conducted. When using compound fertilizer, it is necessary to combine the ground with the ground and concentrate the bean cakes. In the planting position, it is best to choose the north-south direction with the spacing of 1.4m, and plant two rows between each side, with the big row kept at about 90cm and the small row kept at about 90cm. About 50 cm, the plant is about 48 cm, almost the same. In 2000, an acre was planted, and then water is water. The planting technology and management of cherry tomatoes are very comprehensive, so it is recommended to collect them.
Step 4 manage
The first is the management of fertilizers. After planting, you can use water. The previous ear fruit, this time there is no glue dock. The most important thing is to develop the roots of tomatoes. When tomatoes grow to the size of walnuts, the size of broad beans will soar at the second peak. When the third Naka team just blooms, water can be used at this time, usually in ten days to half a month. Some nitrate compound fertilizer can be applied appropriately. About 20 Jin per mu is almost enough. After harvesting, the water of each combination was applied to 40 pounds of potassium nitrate compound fertilizer.
Then there is the management of plants. First of all, tomato cranes and tomato cranes should bloom cherry tomatoes. This time, you need to organize plants. You can choose a sorting method and delete the tomatoes next to it, which can improve the ventilation of tomatoes, reduce nutrient consumption and make nutrients grow into cherry tomatoes. When there are six peaks on the tomato, we should take the tomato to the top and give each fruit a branch. After receiving four tomatoes and waiting for the harvest, we must cultivate a message in time to let him continue to bear fruit, and remove the old leaves in time. When the branches are 2-3 long, then remove the tops, and then re-cultivate new lateral branches and repeat the corresponding methods, but do not leave lateral branches during the management period, otherwise it will affect the expansion of tomatoes.
Then temperature management, tomatoes are more suitable during the day, at 20 degrees-? Between 30 degrees, the temperature is between 15 and 20 degrees. If the temperature is lower than 15 degrees, or 30 degrees during the day, it is not conducive to the reproductive growth of tomato, not conducive to the differentiation of her flower buds, and it is easy to drop flowers, so the temperature during the day is about 27 degrees, and the temperature controlled at night is about 15 degrees, and the fruit growth is about 65438+.
How to prevent tomatoes from falling off the fruit? The first is to control the growth temperature of tomatoes. The temperature can't be too high and you can't be too low. You should keep the light and not be short of water, otherwise it will lead to the degradation of tomatoes. We can use 24-d to add handles. It is best to avoid the high temperature at 9 noon in this job, which can also increase the repentance of tomatoes.
5. Prevention and control of pests and diseases
Tomatoes must be ladybugs and aphids first. The control of ladybugs and aphids can be carried out with 20% insecticide 2000 times, or 50% emulsified oil 2500 times, or 2.5% kung fu oil 3500 times, or 2.5% tin ester 2800 times. For tomato stalks, nitrogen fertilizer can be used reasonably, nitrate, nitrate can be used for excessive nitrogen fertilizer, ammonium carbonate and ammonia nitrogen should not be used as much as possible, and potassium fertilizer should be used carefully. The tomato swells twice, and the conditions for twice appearance can be found. 0. 1% potassium citrate +0.2% glucose can be used, which can increase the contents of potassium fertilizer and sugar in tomato leaves. The planting technology and management of cherry tomatoes are very comprehensive, so it is recommended to collect them.
