What should I do if the tomato seedlings are small? What should I do if the tomato seedlings are pro

This is the problem of slow fruit expansion caused by vigorous growth, which can be solved by timely control of prosperity and increasing the application of water-soluble fertilizer.

1. Timely control of prosperity.

It is not a good thing for vegetables to grow too vigorously, because the rapid growth of rhizomes and leaves will absorb the nutrients required by the fruit, which causes the problem of slow fruit expansion

The first is reasonable watering.

Do a good job of alternating large and small water, summer watering has the dual effect of cooling and replenishing water, but watering too often will lead to too high soil moisture and no root system, resulting in unbalanced growth. Therefore, watering should be carried out in the method of alternating large and small waters: when the soil is dry, large water irrigation is carried out, and when the greenhouse temperature is too high, spraying water is used to reduce the temperature.

The second is reasonable pruning.

Growers can prune tomato branches and leaves to reduce the absorption of nutrients by stems and leaves, and at the same time, it can also facilitate ventilation in the shed and allow the soil to dissipate heat better. By pruning properly, the nutrients drawn from the roots of the tomato can be transferred more to the fruit, which promotes fruit expansion.

2. Reasonable fertilization.

The growth of tomatoes is inseparable from fertilizer, but most growers do not have enough understanding of fertilizer, and the demand for fertilizer is relatively large, but if there is too much nitrogen in the soil, it will often lead to vigorous growth, at this time, it is necessary to control the input of nitrogen fertilizer, and then supplement potassium dihydrogen phosphate, suspended calcium and other elements, mainly to supplement potassium, phosphorus and other elements, you can also use Oasis with roots and seedlings containing amino acid water-soluble fertilizer, with high potassium water-soluble fertilizer to adjust the nutrients in the plant.

In addition to a large number of elements such as nitrogen, phosphorus and potassium, tomato growth also needs calcium, magnesium, zinc, boron and other trace elements, which can promote flower bud differentiation and improve plant growth. Therefore, under the premise of reducing nitrogen fertilizer and increasing potassium fertilizer, the spraying of foliar fertilizer in Oasis can also be carried out regularly, which has a good effect on the effect of fruit expansion.

From a physiological point of view, the vegetative growth is vigorous, and the small fruit is the slow reproductive growth, and the vegetative growth inhibits the reproductive growth, which should be regulated. Can be taken:

1. Control vegetative growth: prune tomato plants and knock off new branches or tops.

2: Promote reproductive growth, spray plant growth regulators such as gouarin, ethephon, etc.

Tomato seedlings do not swell the fruit, or the fruit is small, generally because of the use of too much nitrogen fertilizer, too much nitrogen will not only cause the growth of tomato seedlings, but also slow down the differentiation of tomato flower buds, nutrients are difficult to reach the fruit, so it will cause this phenomenon, you can give tomato foliar spraying, spraying powder powder potassium dihydrogen phosphate + amino acid foliar fertilizer, is conducive to promoting tomato fruit expansion, and at the same time can control the growth of tomatoes, with the root of the flush Shi Ribery Yanwo high potassium water-soluble fertilizer, preferably containing 44 potassium, The puffed fruit is obvious and safe, and there is no harm.

Hello, the aging of seedlings in the middle and late stages of small tomatoes may be caused by a lack of nitrogen, so it is recommended that you supplement nitrogen in time, or to promote the growth of plants. At the same time, it is necessary to pay attention to the prevention and control of pests and diseases, and timely clean up the old and difficult stubble of seedlings to ensure the healthy development of plants.

Tomatoes grow vigorously, and the trees grow quite tall, which affects the fruit, how to control the prosperity?

1.Control the age of seedlings and plant them in time. Strictly control the seedling age, such as the seedling age of the general early-maturing tomato varieties is about 60 days, the mid-late maturing varieties should be 70-80 days, and the autumn tomato seedling age is about 25 days.

2.Prepare for planting early to promote seedlings to slow down. 10-30 days before planting, do a good job of land preparation, base fertilizer, cover the roof film and skirt of the greenhouse, ditch drainage around the greenhouse, etc., so that the humidity in the shed is low and the temperature is high when the seedlings are planted, which is conducive to slowing down the seedlings.

3.The amount of nitrogen fertilizer was controlled, and deep furrows and high furrows were used for cultivation to promote root growth. 4.

Appropriate amount of Hu Dan pruning and leafing, erecting a frame, so that ventilation is good, and using growth regulators such as anti-falling pigment spray flowers to promote fruit setting and inhibit excessive vegetative growth.

Tomatoes only grow seedlings and do not bear fruit, so you need to apply less nitrogen fertilizer to it, and supplement it with some phosphorus and potassium fertilizer to promote its fruit growth, but also do a good job of temperature control measures, the temperature at night is controlled at 13-17 is the best, insufficient light will also cause tomatoes to only grow seedlings and do not bear fruit, at this time you need to supplement light for tomatoes, in order to facilitate its photosynthesis.

1. Reasonable fertilization

Tomatoes only grow seedlings and do not bear fruit, generally because of excessive nitrogen fertilizer application, at this time we need to reduce the amount of nitrogen fertilizer, so as not to its branches and leaves are too vigorous, and then add some phosphorus and potassium fertilizer and trace element foliar fertilizer, so that its fruit can grow.

2. Suitable temperature

Tomatoes like warmth, but if the temperature at night is relatively high, then tomatoes will only grow seedlings and do not bear fruit, this phenomenon needs to do a good job of temperature control measures, generally maintain the temperature at 25-28 during the day, and control the temperature at night at 13-17 is the most appropriate, so as to improve the phenomenon that it does not bear fruit.

3. Supplemental lighting

Tomatoes have a great demand for light, if the light is insufficient, it will only grow seedlings but do not bear fruit, at this time it is necessary to supplement the light to the tomato, so that it can carry out photosynthesis well, and appropriately cut off some excess branches and leaves, so as to enhance the ventilation and light transmittance of the tomato plant.

4. Control moisture

If the daily watering is too much, the branches and leaves of the tomato will grow wildly, so that it will only grow seedlings and not bear fruit, in this case, it is necessary to control the water, so that the tomatoes can bear fruit, pay attention to the tomato fruiting period need to keep the soil slightly moist, otherwise the water is insufficient, the development of tomato fruits will be hindered.

<> water control: Xihong Xujiao persimmon in the seedling period is relatively weak and the root system is not developed, so the absorption capacity of water and fertilizer is not strong, as long as the appropriate amount of watering can promote its normal growth. Fertilizer control:

In the early stage, the amount of nitrogen fertilizer should be controlled, and the use of inferior fertilizer should be avoided, so as to avoid the plant growing vigorously and proliferating due to excess nutrients. Temperature control: The temperature should be controlled at 28-30 °C at the seedling stage, and at 22-25 °C after entering the flower bud differentiation stage, and the temperature should be kept warm in time when the temperature is too low.
