What to do if the seedlings grow, what to do if the flower seedlings grow

Is it that there is less sunlight. Move out into the sun.

Flower seedlings grow and do a good job of pruning, light, watering, and fertilization maintenance management. Cut off the top of the long stems and remove the excess within the distance between the seedlings, leaving a robust flower seedling. Maintain at least 8 hours of sunlight every day, water and fertilize regularly to ensure the nutritional growth needs of plants, and avoid stagnant water and fertilizer.

1. Pruning

Seedlings can be pruned to remove the top of the stems and remove the excess within the distance between the seedlings, leaving a robust seedling. Also cut off some growth pests and diseases, lodging branches, redundant branches, overlapping branches, and diseased yellow wilted old leaves one by one to avoid excessive consumption of nutrients.

2. Illumination

Flower seedlings can be grown with sufficient light, and they can be placed in an outdoor lighting environment when breeding, and maintain at least 8 hours of sunlight every day, which promotes photosynthesis and is conducive to the growth of branches and leaves. It is only necessary to pay attention to the environment where the light is too strong, and do a good job of shading to prevent the occurrence of sun exposure.

3. Watering

It is necessary to control the watering of the seedlings when they are long, for example, they can be watered frequently during the growing season, and gradually reduce or not water during the dormant and cold winter periods. In addition, you can also spray foliar water appropriately to maintain a certain degree of moisture. Be careful not to have stagnant water, and the water temperature should be almost the same as the soil temperature to avoid frostbite to the root system.

Fourth, fertilization

When the flower seedlings are growing, it is necessary to control the fertilization, such as less fertilization during the seedling period, and the fertilizer should be rotten organic fertilizer. During the flowering stage, phosphorus and potassium fertilizer were mainly used, and potassium dihydrogen phosphate foliar fertilizer was appropriately added to promote the growth of branches and leaves. Stop fertilizing after flowering.

When the plant grows, its branches will grow faster, and it will become slender and long, wilted, and it is very easy to lodging, and the color of some branches will become lighter, and the branches are more difficult to support its plants.

What does a plant look like?

When the plant grows, its branches will grow faster, and it will become slender and long, and wilt, which is very easy to lodging, and the color of some branches will become lighter, and the branches are more difficult to support its plants, and there are many reasons for the growth.

Causes of plant growth.

1. The first factor that causes plant growth is the lack of light, long-term in a shady environment, plants can not carry out photosynthesis, and plants will gradually grow, resulting in too fast growth, especially in the high scattering or warm season.

2. When plants are growing, they need sufficient water and fertilizer, but if they apply too much, it will cause excess nutrients, especially excessive nitrogen fertilizer, which will lead to the weakening of the vitality of the root system, so that the plant will grow.

How to deal with plant growth.

1. After the plant has a long pulse, it should first be topped, which can control its growth height and avoid the growth of the top of the main branch from being too high, thus affecting the growth and development of the side buds.

2. When the plant grows, it needs to be moved to a place with sufficient light for maintenance, and there must be a good ventilation environment, so that it can gradually recover its growth.

3. When the plant grows, it is necessary to stop fertilizing immediately, and also reduce watering, so that it can gradually recover, if the effect is not very ideal, you can spray some drugs.

Preventing seedlings from growing and cultivating strong seedlings is one of the important measures for high rice yield. Generally, under the conditions of more fertilization, large sowing amount, high humidity and high temperature, it is easy to produce tall seedlings with high plant height, long leaves and dark green leaves. In order to prevent the growth of seedlings, it is necessary to pay attention to the disinfection of rice seeds and seedling soil, and prevent the growth of seedlings introduced by seedling disease.

Thinning and uniform sowing are used to reduce the sowing amount and prevent the seedlings in the unit area from growing too densely. After the emergence of seedlings, strengthen the fertilizer and water management of the seedling field, delay the seedling water time, keep the seedling plate moist before the two-leaf one-heart stage, and use shallow water irrigation after the two-leaf one-heart stage. After the second leaf stage of early rice, it is necessary to do a good job of ventilation and seedling refining when the sun is high on sunny days, so as to prevent high temperature from causing seedling burning and growth, and at the same time, the amount of weaning fertilizer should be strictly controlled.

According to the characteristics of the variety, paclobutrazol is sprayed, paclobutrazol is sprayed in the seedling leaf and heart stage, the common dosage of general seedlings, 200 grams per mu (15% wettable powder) of late rice seedlings, 100 kg of water; 150 grams of medicine per mu and 75 kg of water were used in the single-season rice seedling field. Paclobutrazol inhibited seedling elongation, dwarf and tillering to cultivate strong seedlings.

Plant growth refers to the slenderness and swaying of small seedlings caused by too much water and too weak light in the seedling stage, which cannot withstand the climatic conditions such as wind and sun, and is not easy to survive.

There are mainly ways to prevent plant growth.

The sowing or planting density should not be too large.

and time seedlings. Strengthen ventilation and light transmission, and control temperature and humidity.

Reasonable fertilizer and water management. Control the amount of nitrogen fertilizer.

Drain the seedlings in time.

Potion control is long. Once the seedlings are growing, in addition to the above measures, Bordeaux liquid (equivalence) spray can also be used, or sprayed with 50 chlormequat 2000 2500 times liquid.

What should I do if the succulent seedlings appear to grow? Teach you a few simple tricks to make it grow short and strong.

Hello, what kind of seedlings are yours?

The reason for the growth of green vegetables may be that the seeds are sown too densely, so before sowing, sprinkle less seeds or sow them evenly. If it is too dense, you can also thin the seedlings to increase the distance and ventilation between the seedlings, otherwise if it is too crowded, nutrition, sunlight and so on will be insufficient.

It is possible that the seedlings grow because they are blocked by other vegetable plants. So get to an open, ventilated, sunny place in time. In addition, after the emergence of seedlings, when they do not grow, excessive application of nitrogen fertilizer is easy to cause growth, so when the seedlings are small, less fertilizer is applied.

The growth of green vegetable seedlings is also closely related to watering. Because the pots or vegetable seedlings may be placed indoors, the evaporation is very small, and the vegetable seedlings are very easy to grow when they are watered too much. When watering, water thoroughly at once, and then wait for the soil surface to dry before watering.

The growth of green vegetable seedlings is related to temperature, fertilization, and ventilation. If the temperature is too high, it is easy to cause growth. Especially if the humidity is high and it is not breathable, so if it is an indoor plant, it is necessary to increase ventilation and reduce the amount of watering.

If it is a seedling cultivated in a seedling box, it should be transplanted and planted in time. If the transplanting is late, the growing space is too small and the light is insufficient, so the seedlings will grow longer and longer, resulting in overgrowth. If you plant it in a larger pot, it will slow down the growth.

After the seedlings grow, on the one hand, increase the sun, less watering, increase ventilation, and the other method is to tear off some of the more thin and serious seedlings, and then you can add some soil appropriately, and cultivate some soil near the seedlings, a few centimeters thick can be, not too much. If the growth is too strong, you can also choose to re-sow seeds.

Fertilization should be mastered at the right time and in the right amount, and at the same time, it is necessary to grasp the season and time. Generally speaking, fertilization is best when the flower leaves are pale yellow and the plants are weak; Vegan fertilizer was applied at the seedling stage, high phosphorus water-soluble fertilizer was mainly applied at the flowering and fruiting stage, and high-nitrogen water-soluble fertilizer was mainly applied to foliage flowers. In winter, the temperature is low, the plant grows slowly, and most flowers are in a state of growth stagnation, and generally no fertilizer is applied; Spring and autumn are the peak period of flower growth, roots, stems, leaves grow, flower buds differentiate, young fruits swell, all need more fertilizer, should be appropriately applied more top dressing; In summer, the temperature is high, the water evaporates quickly, and it is the vigorous growth period of flowers, so the concentration of top dressing should be small, and the number of times can be more.

The specific fertilization time is generally in the evening, and fertilization should not be avoided around noon, because the soil temperature is high at noon and it is easy to hurt the roots. Generally, it is necessary to master the "four more, four less, and four no", that is: yellow and thin more, more before germination, more before pregnancy, and more after flowering; Less application for growth, less application for germination, less application for flowering, and less application in the rainy season; Don't apply for long, don't apply for new planting, don't apply for summer, don't apply for dormancy.

It is necessary to grasp the principle of "thin fertilizer and diligent application", that is, "eat less and eat more".

As a result, a large amount of nutrients are consumed, and the tree cannot flower and bear fruit when it reaches the age of fruiting, or the flower is small and the yield is low.

The main reasons for the growth of fruit trees are as follows:

First, the reason for the variety or seedling itself Such as peach, plum, pear, chestnut and other varieties are easy to grow; "The north-to-south migration of the fruit" is also prone to growth; The rootstock, scion, and seedling technology of seedlings will also grow. Generally speaking, seedlings grown from seeds are easy to grow.

Second, the reason for pruning and shaping When the young tree is shaping, the large branches are left too little or clustered, the nutrients are too concentrated, the side branches are less or cut off too much, and the subordination of the main side branches is not obvious; When pruning, in summer, do not pay attention to the top control of the long shoots in time, and when pruning in winter, the strong branches are too heavy, and the small branches are cut too much, which will also cause overgrowth.

3. Improper fertilization In the early years, nitrogen fertilizer, chemical fertilizer or large fertilizer and large water are applied, and little organic fertilizer is applied, and phosphorus and potassium fertilizer are not noted; If the soil is too much moisture for a long time, it will also grow.

To prevent fruit trees from growing, we must first plant grafted seedlings, not real seedlings. Seedlings are easy to grow, and flowering and fruiting are late. The rootstock of grafted seedlings should be selected from native and dwarf varieties; For rootstocks with developed and long taproots and few lateral roots, part of the taproot should be cut off or the excessively long taproot should be transformed into a circle when transplanting, which can promote the multiflority of lateral roots and dwarf seedlings; It is necessary to select the branches that are sunny in the middle, robust, and free of diseases and pests from the adult mother trees that have been abundantly produced as scion, and do not use long branches and shade branches as scion, let alone take branches from young and unfruitful plants as scion.

When planting, the taproot of the seedling should be appropriately shortened to promote the growth of lateral roots and the plant is not easy to grow.

In the pruning and shaping, it should be mainly topped in summer, supplemented by winter pruning, and the length can also be controlled by pulling, bending, twisting and other measures of the long branches; When pruning in winter, the long branches should be lightly pruned, and the extended branches of some main branches should be moderately shortened; In the shaping, the branches drawn out of the strong branches should be appropriately left, and the side branches should also be left as fruiting branches, so as to control the growth of the shoots, and the lower branches can bear fruit early, as long as they do not mop the ground, they should be retained, so that they can bear fruit early, and they can control the growth of the plant.

For Wang trees, the length can also be controlled by cutting off the main branches that are too long, circumferentially cutting branches, etc.; If the new shoots grow in the form of elongation, the growth of the branches can be inhibited by spraying growth regulators such as B-9, paclobutrazol, and mequartin.

In terms of fertilization, we should pay attention to the application of organic fertilizer, young trees to the late stage of growth, to control the application of nitrogen fertilizer, water, to increase the application of phosphorus and potassium fertilizer, after the new shoots grow to a certain length, we should pay attention to the control of fertilizer and water, too much water orchard, to do a good job of drainage, if necessary, can be carried out to expose roots, dry roots, and even break roots. By taking these measures, it is possible to control overgrowth of branches and vegetative growth.
