How to grow cherry tomatoes? High-yield cultivation techniques for cherry tomatoes
Cherry tomato is a tomato variety that can be used as a fruit. It is characterized by a mini cute, unique taste and rich in nutrients. It is very popular in people's daily life. The following are the cherry tomato cultivation techniques for your reference. 1, planting time Winter and spring can be used in ordinary and excellent solar greenhouses. Generally, in late October, it will be planted in early November, and in mid-January and late February to early February, it will be planted in March and March to June.     2, strong seedling standards High quality seedlings are the basis for high yields. The standard of strong seedlings of cherry tomatoes is: the stems are thick and erect, the internodes are short, there are 7-9 large leaves, the leaves are dark green, rich, the leaves are slightly purple, the roots are developed, the plant height is 20-25 cm, and the stem is 0.6 cm thick. Left and right, the whole plant is umbrella-shaped, and there are small flower buds before planting, no pests and diseases.     3. Sowing date and seedling age The seedling age is about 70 days. If the geothermal line is used for heating, the seedling age can be shortened to about 50 days. The sowing date is determined by the age of the seedlings, the period of planting and the period of listing.     4. Preparation before planting 1 Prepare seeds, 40-50g of seeds per acre, prepared in advance. 2 bed soil preparation. One of the following recipes can be used to seed the bed soil according to its own conditions. A, garden soil 2 / 3 + decomposed horse manure 1/3. B, garden soil 1/3 + sieve fine furnace slag 1/3 + decomposed horse manure 1/3 (the garden soil is more sticky when used, calculated by volume). C, charcoal 60% + garden soil 30% + decomposed chicken manure 10% (by volume ratio).     5. The ratio of the seedbed soil is 6 parts of fertile garden land, 4 parts of decomposed organic fertilizer, the amount of bed soil required is: the thickness of the seed bed is 8-10 cm, about 100 kg per square meter of seedbed; when the soil thickness of the seedbed becomes 10-12 cm, each The square seedbed needs about 140kg of soil. Generally, the bed is 5 square meters per mu, and the seedbed is 50 square meters. At the same time, the bed soil must be disinfected, and the bed soil is sprayed with 40% formaldehyde 300-500 times, one layer is sprayed, and then plastic is used. Film coverage.     6, seed disinfection Eliminate the pathogens carried inside and outside the seed and reduce the source of infection. Usually used to soak seeds. The method is as follows: first soak the seeds in cold water for 20-30 minutes, remove them and put them at about 50-55 ° C, stir constantly in hot water, and add hot water at any time to keep the water temperature at 50 ° C for 20-30 minutes. After being cooled to room temperature, soak for 4-5 hours, remove the cloth and germination.     7, germination The seed germination temperature is 20-28 ° C, the seeds are dried to discrete, wrapped with a moist towel or gauze, placed in the vicinity of the germination box, incubator or fire, germination at 25-30 ° C, during the germination process, daily Wash the seeds 1-2 times with warm water, and when most of the seeds are white, they can be sown.     8, sowing After the cherry tomato seeds are germinated, the water outside the seeds is dried, and the bottom water is poured in the seed bed. The water temperature in the winter is 30 ° C, the soil temperature is low, and the water temperature can be higher. After the water seepage, the seeds are Spread evenly on the bed, and then cover the fine soil of the sieve about 1 cm.     9, water management Watering should be strictly controlled throughout the nursery period, no water is poured, and water is poured 5-7 days before planting.     10, colonization     10.1 Before planting Deducting the membrane before planting can increase the ground temperature, apply fully decomposed organic fertilizer per acre, and disinfect the greenhouse 3-4 days before planting. The method is: use sulfur powder, chlorothalonil and saw foam, press 0.5-1:1 : 5kg ratio mixing, igniting smoked smoke, after 48 hours of sealing, ventilation for 24 hours.     10.2, colonization period When the ground temperature of 10 cm deep soil is stable above 8 °C, it can be planted in the middle of January and the beginning of next February.     10.3, colonization method The plant is planted with broken membrane water, two rows per raft, the limited growth type is 25-30cm, the seedlings are 3000-3500 per acre, and the non-fertilizer growth type is planted 2000-2500.     11, post-plant management     11.1 Temperature and humidity management At the beginning of planting, in order to promote slow seedlings, it is necessary to maintain a high temperature and high humidity environment. After the seedlings are slowed down, the air is adjusted to adjust the temperature and humidity, and after watering, the air is released in time to prevent the disease from being caused by excessive temperature.     11.2 Water and fertilizer management After the seedlings are slowed down, the water should be replanted to make a small water and then start the seedlings. When the first and second flowering ears are flowering, the seedlings are finished, the water is poured once, and the human waste is 1000kg. After 1 week, the water is poured again, and then the soil, the weather and the seedlings are watered in time. The soil is dry and wet, and the urea is chased once every 1-2 times, 10-15kg per mu. 11.3, plant adjustment Single dry pruning, timely removal of tillers, nylon rope hanging vines, due to long harvest period, nylon rope must be firm and not easy to age. Every 8-10 spikes are topped, or the bars are dropped at any time to make them grow indefinitely. Timely to remove the old leaves, and insist on thinning flowers and thinning.     11. 4, hormone preservation Spray with 15 mg/kg of 2.4-D scented flower or 40 mg/kg of anti-dropper. However, it must be noted that the flower is not repeated, and the concentration is gradually decreased with the increase of temperature. The whole growth period is treated with hormones, otherwise it is easy to form empty spikes or extra small fruits.     12, harvest Cherry tomatoes are collected and charged, generally do not need artificial ripening, and picking different ripe fruits at any time as needed. Cherry tomatoes look like cherries, a small mini, is a very popular variety, has a good planting prospects, the above is about its detailed planting methods, you can learn from.
