Cherry tomato with cherry tomato has strong adaptability and good disease resistance. It is a kind of fruit tomato with long harvest period, and the yield per mu can reach 3000 kg. With the continuous expansion of market sales and rising prices, you can benefit from planting in the same year. Of course, if you want to grow good and sweet cherry tomatoes, you need to pay attention to the following cultivation points.
First, sow and raise seedlings
Soak the seeds of cherry tomatoes in 10% trisodium phosphate aqueous solution for 20-30 minutes, rinse them with clear water immediately after taking them out, and remove the chafed seeds, then soak the seeds in warm water of 50 degrees for 8- 10 hour, and after soaking, wrap all the seeds with sand cloth and place them for 25-30 hours.
Second, land preparation and border preparation
When planting cherry tomatoes, we'd better choose sandy loam with convenient irrigation and drainage, fertile soil and good ventilation and permeability. In order to ensure the yield and quality of the cherry tomatoes, the soil preparation should be done as early as possible, with three plows and three harrows, and the base fertilizer should also be mainly organic fertilizer, generally according to the standard of applying 4,000 kg of decomposed farmyard manure per mu. In plots with poor fertility, we can also cooperate with the application of calcium magnesium phosphate fertilizer 15-20 kg. After the soil preparation is completed, the land will be leveled into a high ridge with a width of 1 m and a height of 30 cm, and the trench width will be kept at 40 cm.
Third, reasonable colonization
Reasonable planting can determine the final yield of cherry tomatoes, because the population density will affect the growth state of cherry tomatoes, and then affect the yield and quality. Under normal cultivation, when the seedlings have five true leaves, we can carry out fixed planting and double-row planting, and the spacing between plants should be 30-35 cm, and 2500-2800 plants can be fixed per mu of planting land. When planting, we should strictly control the depth of planting seedlings, and the depth of planting seedlings should be based on not burying cotyledons.
Four, water and fertilizer management
In order to ensure the normal growth of cherry tomato plants, we need to supply fertilizer and water well during the whole growth period. In the process of cherry tomato cultivation, the topdressing for 1 time should be carried out within 2 weeks after planting, and 500-800 kg of clear manure water should be poured on an acre of land; The second topdressing should be based on quick-acting fertilizer at the beginning of flowering and fruiting, and ternary compound fertilizer 15-20 kg should be applied per mu; Before the first ear of fruit ripens, we need to apply strong fruit fertilizer, and use 20-25 kilograms of compound fertilizer per mu. After the cherry tomatoes entered the full fruit stage, the demand for fertilization reached the peak, so water and fertilizer should be supplemented in time, and 5 kilograms of compound fertilizer should be applied with water every time, and the interval should be 5 days, so as to keep the soil moist enough.
Fifth, tie the vines and prune them
When the plants of the cherry tomatoes grow to a height of 30 cm, we can irrigate them 1 time, insert a wooden stake for each plant while the land is wet, plant an upright frame in one row, and plant a herringbone frame in two rows, tie a layer of vines on the frame every 30 cm, tie the vines under the inflorescence, and tie the inflorescence in the direction of the passage, so that the flowers can be treated and harvested with auxin the future, and the inflorescence must not be caught between the frame and the stem. The vines should not be tied too tightly to make the stems thicker. If the plant grows in vain, it can be tightened slightly, and finally the top should be tightened.
After the first inflorescence of the cherry tomatoes blooms, we will start pruning. When pruning, we should determine the operation according to the planting density. Generally, the main branch and the thicker lateral branches under the first inflorescence are left as fruiting branches for densely planted pruning, and it is best to remove all the lower lateral branches. The sparsely planted pruning leaves the main stem and 1 lateral branches under the first inflorescence, so that they can grow and bear fruit hand in hand. In addition, only one branch needs to be left on the two fruiting branches, and the other branches can be gradually removed to become four-vine fruiting branches, and each vine needs six ears to ensure high yield.
Sixth, prevent falling flowers and fruits
Vegetable farmers who often plant cherry tomatoes know that cherry tomatoes are particularly prone to falling flowers and fruits, which seriously affects the yield. If the yield is reduced, it will be completely lost. In order to effectively avoid falling flowers and fruits, we can take two measures to prevent them. First of all, artificial pollination is used to vibrate the flowers that have already opened, so as to make the pollen scatter and fall on the stigma for pollination; You can also collect pollen manually and dip it on the female flower with a brush. At present, in the field production, it can be used to spray flowers after dissolving in water, and the effect is excellent.
Conclusion: When I planted cherry tomatoes, I used disease-resistant varieties, so basically no pests and diseases occurred, so I don't know much about the pest control of cherry tomatoes. I hope friends who know how to do it can help me supplement it. When the cherry tomatoes are ripe, we should harvest them in time and pick them by hand from the abscission layer of the fruit stalk. In order to keep the flavor and facilitate transportation, we can pick it when it is ripe.
