Do I need a rooting agent when a seedling comes back?

Hello, colonization needs rooting agent to regulate, plus microbial agent effect is better.

Strawberry fertilization management.

Strawberries need more fertilizer from planting to flowering and fruiting, in addition to applying sufficient base fertilizer, but also timely supplement fertilizer, can be applied strawberry special fertilizer or 10 kg of diammonia phosphate per mu at the fruit expansion period and the beginning of harvest.

Combined with watering, the furrow application effect in the form of 200 times liquid fertilizer is better, and the field with good growth is only sprayed with potassium dihydrogen phosphate 2-3 times, which also has a certain yield increase effect, and is not sprayed in principle during the flowering period. The principle of fertilization in the fruit picking field is to be suitable for n weight p and k, and a reasonable ratio relationship must be maintained in order to obtain higher yield and maximum benefit.

Extended information: 1. Strawberry fertilizer absorption can be divided into four stages when cultivated in the open field:

1. During the 4-month growth period from planting to natural dormancy, the nutrient absorption is relatively low due to plant dormancy. According to the dry matter analysis of plants, the absorption ratio of nitrogen, phosphorus and potassium at this stage was 1::, and the nitrogen absorption was the largest.

3. With the rise of air temperature and soil temperature, the plant enters the vigorous growth period from the budding stage to flowering and fruit setting, and the absorption and consumption of nutrients reaches the peak in this period, and the absorption ratio of nitrogen, phosphorus and potassium is 1::, and the absorption ratio of potassium is further increased.

4. The proportion of nitrogen absorption by plants from flowering and fruit setting to fruit maturity decreased, phosphorus and potassium absorption increased, and nitrogen, phosphorus and potassium absorption increased. The ratio is: , and the proportion of potassium absorption reaches its peak.

2. When the greenhouse promotes cultivation, strawberry fertilizer absorption can be divided into three stages:

1. From planting to flowering, the absorption of nitrogen, phosphorus and potassium accounted for % and 14% of the total absorption during the whole growth period.

2. Flowering to the first.

The fruit swelling and ripening period of the first, second and third inflorescences is the first peak period of strawberry yield, accounting for more than SS% of the total yield, and absorbing more nutrients;

3. From the end of the first harvest of strawberries to the end of the whole harvest, it is the second peak of strawberry fertilizer absorption. In the section.

In the second and third stages of fertilizer absorption, the characteristics of cultivation are similar to those of open field cultivation, and the absorption of phosphorus and potassium fertilizers increases, especially the absorption of potassium is more prominent. To sum up, we can use hormone-free Yanwo water-soluble fertilizer, foreign dual technology, decompose nutrient macromolecules into small molecules, easier for crops to absorb, Yanwo water-soluble fertilizer is easy to absorb, and the absorption and utilization rate can reach 80%.

A root seedling needs to use a rooting agent after it comes back, and the root system can be sent out faster after using the rooting agent.

Generally speaking, it is not recommended to mix rooting agents and pesticides. Because rooting agent is a plant hormone that promotes plant growth, while pesticide is a chemical substance that kills insects, fungicides or weeds, the mechanism of action of the two is different, and the mixed use may produce adverse reactions and affect the growth and health of plants. If rooting agents and pesticides need to be used, it is recommended to use them separately, follow the instructions for use, and avoid mixing them.

Pruning of cuttings before the use of rooting agents.

I don't know if you are using a pure microbial rooting agent, if it is a microbial product, it doesn't matter if you spray more, like Gymboree rooting agent is a pure microbial product, does not contain any hormones, after application, it has fast roots, fibrous roots, strong seedlings, and can also improve the survival rate of transplanting, promote weak seedlings to strengthen seedlings and other effects, without any ***.

I use the rooting agent of Happy Forest, which has fast rooting, large root quantity, good growth and high survival rate, and the following is how to use it in the manual:

Soaking: Dilute this product 1000 times, soak for 6 hours, and then dry it for cuttings.

Quick dipping: Depending on the difficulty of rooting, dilute this product 50-100 times. Dip for 3-6 seconds for cuttings.

Root irrigation: 1 tree per bag for trees with a DBH of less than 10cm. Trees with a diameter of 20cm and above will increase or decrease the dosage according to the difficulty of rooting.

Powerful rooting agent.

1.When the temperature is above 20°, it can be rooting in 5-7 days.

2.It can be sprayed and irrigated when transplanting.

Hormone rooting agent can only be used once when transplanting, or when the root is injured and the root is weak, otherwise it will affect the growth of branches and leaves, delay flowering and fruiting. Last month I transplanted a few triangle plum with a diameter of 3 5 cm, transplanting with "863 strong rooting agent, the effect is very good, about 10 days all the buds, 30 days after the branches and leaves are luxuriant, at the beginning of this month dug out a small triangle plum, (because I feel that the planting position is not good to replant), after digging out found that many white new roots have grown, after replanting and watered 863 strong rooting agent, there are still some left, I thought don't waste it, poured the remaining rooting agent on the side of a good growth triangle plum hope to grow better, But I was wrong, the one that was watered with rooting agent can no longer see growth, and now 20 days have passed, and the other few have grown a lot taller, and there are many flower buds about to bloom, and the two ones that have been watered with rooting agent are still the same, and the growth is almost stagnant, but it does not die and does not wilt, until now. Because the growth of the aboveground and underground parts of the plant is coordinated, if the rooting agent is applied artificially to break this coordination, it will lead to excessive flow of nutrients to the underground part, and the growth of the aboveground plant will be inhibited, resulting in poor growth.

Analysis: It is not appropriate to rely only on rooting agent for poor root system, first of all, the specific cause of poor plant root system should be identified, if the disease infects the root system, or transplanting damages the root system, the disease should be first prevented and at the same time the rooting agent should be irrigated to promote new roots, of course, this will inhibit the growth of branches and leaves. If malnutrition leads to poor root system, you can properly apply phosphorus and potassium fertilizer such as potassium dihydrogen phosphate, my friend has used the hormone-free "Guoguang Genbao" can be used in the plant growth period, the effect is good, can be about a month to root at the same time does not inhibit the growth of branches and leaves, is a nutritional rooting agent, but not suitable for cuttings and transplanting and other occasions that need to take root quickly.

This depends on the object of use and the season of use, under normal circumstances, it can take root in 10-15 days after using the rooting agent of Happy Forest.

Pruning of cuttings before the use of rooting agents.

Rooting and strong seedlings, not only to prune branches and rooting agents and the like, but also to prevent root rot and yellow leaves This phenomenon is used together.

1.Ingredients of rooting and seedling strengthening agents

Rooting raw materials + fertilizers.

2.The main ones that play the role of rooting are:Naphthalene acetic acid, indole butyric acid and other original drugs, generally added to the finished rooting agent, common finished rooting agent like happy forest rooting powder.

Fertilizer is to play the effect of strong seedlings mentioned later, and the roots are raised when the roots are good3.How to use rooting and seedling strengthening agent:This kind of agent is generally used 2 or 3 times, the common method is irrigation, the dilution factor can be used in accordance with the instructions for use, and the rooting powder of happy forest trees used before is 500 times diluted.

There are three types of rooting agent usage, which are:

1) Seed dressing, soaking, this specific concentration dilution depends on what kind of rooting agent you buy, for example, the commonly used indole fresh ester rooting agent specification is 40ml, you need to add 5 kg of water, and if you soak the seeds, it will take 5-8 hours to dry it.

2) Irrigate the roots, mix 50-100 kg with water, and evenly drip irrigate the roots of the plant, 100-250ml per plant.

3) Dip the roots, 40ml mixed with 33-5 kg of water, evenly soak the flower seedlings for 1-2 hours for transplanting and cuttings.

Pruning of cuttings before the use of rooting agents.

Pruning of cuttings before the use of rooting agents.

Spring flower cuttings are too simple, so many rooting methods can be just choose one.

According to varieties, easy-to-root varieties do not use rooting agents, such as glass emerald, chrysanthemum, moon season, etc. For safety, it can be inserted in water and then transplanted into the soil after rooting.

It should be possible, but it will be very slow, and the survival rate will not be very high, and the use of rooting agent still has a certain effect:

The active ingredients of Gymboree microbial rooting agent: BYM bacterial agent fermentation broth, biochemical humic acid, active rooting agent, photosynthetic accelerator, virus inhibitor and a variety of trace elements.

Uses: It can be used for seedlings, seedlings, plant transplanting, and the entire growth period of plants

Function: Promote seed germination and consistent seedling; Rooting seedlings are strong and enhance vitality; improve the survival rate of transplanting; Resistant to disease and heavy stubble.
