What medicine is used to restore the development of rice roots?

Restore the developed root system of rice, and you can use Luxcar, etc.

The crop is cultivated by technology.

The crop likes high temperature, humidity and short daylight, and has low requirements for soil.

The south of China is the main producing area, and the northern provinces are cultivated.

1. Seed treatment.

Seed treatment is a prerequisite in planting technology, generally before planting, the selected seeds are cleaned and disinfected in potassium permanganate solution, and then placed in a mesh bag for germination treatment, and the temperature can be maintained at about 30 to germinate quickly.

2. Land preparation treatment.

In order to ensure the fertility of the cultivation medium, it is generally necessary to combine the cultivation and weeding treatment when preparing the land, and then add an appropriate amount of organic fertilizer and superphosphate, potassium sulfate and other fertilizers to the soil, mix and stir evenly, and then add a small amount of dixone for sterilization.

3. Transplanting treatment.

The germinated seedlings are transplanted into the soil, do not cultivate too densely, keep the plant row spacing at about 10 cm, hold the seedling roots by hand, insert the root system into the soil, it is best not to be too shallow, the root system should be kept completely covered by the soil, and it can also be carried out with a seedling machine, which is faster.

4. Post-planting treatment.

If there is a lack of seedlings after planting, it is necessary to replenish the seedlings in time to ensure the original planting density, and frequent irrigation treatment is required during the growth period, and the water can be increased during the seedling period, generally only need to be submerged to one-third of the plant, and then the ammonium sulfate fertilizer can be added appropriately according to the growth situation.

5. Weeding treatment.

It is best to carry out weeding treatment frequently after planting, and herbicides can be applied to it one week after planting, mainly oxatrione, and when the growth is better, benzylthioyl herbicides can be added to the fertilizer to mix and spray to avoid weeds affecting the normal growth of plants.

Rice seedlings, moderate amount of water, appropriate amount of base fertilizer, spraying to promote the development of the root system.

After the rice seedlings are planted in the mud, the seedlings are dried for 2 to 3 days, and the seedlings are promoted to germinate and take the roots to strengthen the roots, and the seedlings grow and develop rapidly, and the moderate water seepage is carried out when the seedlings turn green.

Dry long roots and wet long shoots. Water control, application of root strengthening agent and paclobutrazol, etc.

The medicine is not good, use tons of powdered organic fertilizer per mu, find a point of land to do a comparative test, and the effect will come out in a few days.

If the rice grows too high, calcium cyclic acid, paclobutrazol, uniconazole, etc. can be used.

Rice peak control period and method

Rice control period

In fact, the purpose of rice control is the same as that of corn and wheat, which is to prevent lodging in the later stage. As for the rice locust talc at what period of the control effect is good, it is generally recommended to carry out in the early stage of rice tillering to before jointing, this period of spraying the control agent can effectively shorten the base 1 to 3 nodes of the node spacing, not only can increase the thickness of the base internode, short and strong roots, but also promote the absorption of water and fertilizer, so as to improve the toughness and strength of the stem, make the plant robust, and effectively improve the lodging resistance of rice in the later stage.

Methods for controlling the prosperity of rice

It is recommended to use calcium cyclic acid, paclobutrazole, uniconazole and other drug control agents for rice wang control, such as 15% calcium cyclic acid and 10% multi-effect methylpiperazonium, which have a significant effect on wang control, which is helpful for rice to achieve the dwarf and strong of the plant, enhance the ability to resist lead lodging in the later stage, and then achieve the purpose of increasing yield.

In the same way, when using rice to control the amount of the agent, the release of dwarf can improve the lodging in the later stage, but it is not that the shorter the plant, the better, do not let the excessive spraying of Bi cause the plant to become shorter and shorter, so that the purpose of increasing yield can not be increased, but will cause a decrease, so the rice control agent should pay attention to the dosage and concentration of use.

It is generally recommended to control the plant height and thicken the stem in the same way as the spraying of corn and wheat crops (with other trace elements) to control the plant height and thicken the stem, so as to reduce the occurrence of lodging in the later stage.

Attention should be paid to the dosage and concentration of rice control agents to avoid unnecessary trouble.

Summary. The field control of rice foliar growth should be used in June and August, when the rice leaves are wide and a large number of jointing stages, and the dosage per mu is 200 500 grams of chlormequatin.

Hello dear, field control rice foliar growth with should be treated with nicotine. Nicotinoid is an effective insecticide that can effectively control the growth of rice foliage. Nicotinoids can be applied by nicotine emulsifiable concentrate or nicotine potion, and attention should be paid to refer to the pharmacopoeia and packaging instructions when applying, select the appropriate application ratio and frequency, and use effective protective measures for application.

Can you use quartin.

OK. It can promote foliar growth and enhance disease resistance, has good environmental adaptability and heat tolerance, and increases rice harvest. In addition, mequat can also inhibit water loss and prevent leaf curling in rice leaves, thereby promoting the growth of wild rice and promoting the distribution of nutrients on leaves.

When and how much to dose.

Field control rice orange sedan foliar growth with chlormequat should be used in June and August, round rice leaves are wide, a large number of jointing stage, the dosage per mu is 200 500 grams of mequatin.

Remember to fertilize in strict accordance with the instructions for use in the instructions, and do not overdose or fail to use up in time after unpacking, so as not to cause field pollution.

Pro, the field controls the foliar growth of rice and inhibits its growth with paclobutrazol. Rice grows, and paclobutrazol inhibits its growth. Nitrogen control, application of chlormequatin, promote effective tillering.

Rice growth is crazy and is controlled with paclobutrazol spray before jointing. The amount of nitrogen fertilizer can be controlled, and the ear beam can be sprayed with an appropriate amount of plant growth regulator in severe cases. Reduce the amount of nitrogen fertilizer used, and spray paclobutrazol to control the growth of the population.

Seeing that the rice grows very well, paclobutrazol inhibits its growth. Nitrogen fertilizer can be controlled for rice growth, and paclobutrazol can be used to control growth. Rice growth is controlled by spraying paclobutrazol potassium dihydrogen phosphate.

Spray paclobutrazol, increase potassium fertilizer and calcium silica fertilizer, and repeat the field until the control is normal. It mainly carries out fertilizer and water control management, and at the same time uses plant growth regulators according to its situation.

Summary. Dear, hello, it is a pleasure to serve you: Rice rooting agent is a plant growth regulator that promotes rice rooting, and it can generally be done in the following ways:

1.First of all, healthy and disease-free rice seedlings should be selected and removed from the seedbed. 2.

Soak the roots of the rice seedlings in water and let the dirt on their surface be suspended in the water. 3.Soak with rice rooting agent.

Usually, a bag of 5 grams of rice rooting agent is put in an appropriate amount of water, let it dissolve evenly, and then soak the rice in it for about 10-15 minutes. 4.Take out the soaked rice seedlings, and dry the surface for a while, so that the drug is evenly distributed on the rice, so that it can be absorbed more fully.

5.Clamp the rice in the root-prone area and gently insert it into the seedbed or explant. 6.

After that, add water and water moderately, paying attention to controlling soil moisture and light, which can promote the growth of rice.

Clamp the rice in the rooting area and gently insert it into the seedbed or explant. 6.After that, water is added and watered moderately, paying attention to controlling soil moisture and light, which can promote the growth of rice.

The first slip that needs to be paid attention to is that when using rice rooting agent, it should be used in accordance with the instructions for use, and should not be used excessively, so as not to affect the growth and development of rice. In addition, before use, you should understand the scope of application, use methods and precautions of the agent, so as to achieve better results.
