Summary. Cedar new seedlings: spray before emergence after cedar sowing, 60---100 ml per mu of forest Huier, the ground is closed, and the seedlings such as cedar, Pinus tabuliformis, spruce, whitebark pine are safe, and the weeding effect is good;

For seedlings of 2 years or more, about 75 ml of forest use per mu, 30---45 ml of fine killing, 30---45 kg of water, mixed control, the effect is very good.

What herbicide works well in cedar fields without harming seedlings?

Hello, I am helping you to inquire about the relevant knowledge and will reply to you immediately.

For weeding of cedar seedlings, it can be mainly used for forest Huier, which can assist in the control of herbicides and is safe for cedar seedlings.

Cedar new seedlings: after cedar sowing before the emergence of seedlings, 60---100 ml per mu of forest Huier, the ground is closed, and the seedlings such as cedar, Pinus tabuliformis, spruce, whitebark pine are safe, and the weeding effect is good; For seedlings of 2 years or more, about 75 ml of forest use per mu, 30---45 milliliters of celery mold are killed steadily, 30---45 kg of water is used, and the effect is very good. Siyan.

What herbicide is used after transplanting annual pine seedlings? There are also those that do not affect the fruit trees.

1.The herbicides that have not been used are biocidal herbatide stimulants such as paraquat, glyphosate, glucoammonium lead flush phosphine isopropylamine salts, etc., which are more effective, 2Do not spray onto seedling leaves when in use.

You can choose glyphosate (more than 30% content is good, such as Feida glyphosate series, Feida red herbicide, will not have residues on the soil, does not affect the growing plants, but do not spray on the leaf surface when spraying, otherwise there is pesticide damage), can kill grass roots. Paraquat can also be used, but paraquat does not kill roots. With these herbicides, it is necessary to pay attention to the spraying can not spray the leaves of useful plants, otherwise there will be pesticide damage.

With Huier or Goer, as long as you pay attention to the time of medication, do not use the drug about 4 weeks after transplanting, and then you can do it.

It is a "he." Wide. Sha weed" is the magic of elimination. Once applied, cut the grass and remove the roots, there is no grass in one season. Ten times stronger than glyphosate and paraquat.

2. Fragrant aconite against malignant weeds. There are special effects. One application. Three years without birth. No, no resurrection.

3. Safe for grapes. (But focus on directional spraying whenever possible.) ).Do not spray on grape leaves, especially on grape heads, where grapes grow.

4. Good for the environment. No drift, no residue, no pollution.

Two. Effect. Fruit:

This product is a systemic herbicide. The weeds died completely. But die slowly.

In general: broad-leaved weeds are effective in three days. Died in a week.

Poaceous weeds are effective in a week. Ten days to die. Cyperaceae weeds, such as malignant weeds such as aconite.

Results in 10 days. Twenty days later, it is guaranteed to die of "rotten roots". No more resurrection.

Three. How to use: This agent must be diluted twice, that is, pour the powder into a small bowl and add a small amount of water to mix and completely dissolve.

After making the blister-free pharmaceutical mother liquor, pour the mother liquor into the sprayer and add enough water. Do not pour the powder directly into the nebulizer for the secondary dilution method. It's critical.

If the secondary dilution method is not used correctly. There are also blisters in the potions. It is easy to produce pesticide damage.

Every 660 square meters with 2 mixed water 25 30 kg, spraying should be meticulous and thoughtful, so that no heavy spraying is not leaked.

Four. Notes:

1) Keep the soil moist when using medicine.

Sprayers that have used other pesticides must be cleaned.

Such as soil drought. If the temperature is more than 28, it is easy to produce pesticide damage, and in the high temperature season, it can be used when the temperature is low in the day.

2) Please pay attention to ventilation when using the greenhouse, and the greenhouse should be used seven days after removing the film; Otherwise, it is easy to cause drug damage;

3) If the product has not been used in the region or customer, it should be tested in a small area before use; Keep it sealed, dry and in a cool place, away from children, food and feed;

Pinus tabuliformis and Pinus sylvestris sylvestris var. second, herbicides are not suitable for use at the seedling stage; Third, when using herbicides for seedlings more than two years old, the amount of herbicides should be used in strict accordance with the instructions, and it is best to do experiments in the local area before using them in a large area. Fourth, although the use of herbicides is more labor-saving, it is still advocated to use manual weeding, which is not only safe and effective, but also has the effect of moisture preservation and soil loosening on the woodland, and can also choose to use small lawn mowers or appropriate grazing for weeding.

For conifers such as Pinus tabuliformis, Spruce, Larch, Pinus sylvestris and Arborvitae orientalis, selective herbicides should be the main herbicide, which is safe for seedlings. After years of experiments, we have concluded that using forest Huier as the main herbicide, and then assisting in precise and stable killing, can effectively and safely solve the problem of weeding in forestry nurseries. The specific techniques used are as follows:

1) Coniferous new seedlings: use drugs before emergence after sowing. That is, spraying on the 2nd day after sowing.

After sowing the seeds, cover with soil and then spray. When spraying, the bed surface should be moist (such as after sprinkler irrigation or after rain), flat, and there should not be too many plant residues, dead leaves and too large soil clods. It is advisable to choose windless weather and avoid heavy rain for 6 hours.

Pay attention to spraying evenly when spraying, and do not omit it. Do not turn the bed again after spraying. 50-100 ml of forest Huier per mu, 1 bag of high-efficiency additives for forest, and 45-60 kg of water.

The second time in the seedling 60 days after the drug (in the seedling 6-8 weeks can not be used, the standard of judgment is the formation of secondary lateral roots of seedlings), 30-75 ml of forest per mu, 30-45 kg of water. If there are grass weeds, add 20-30 ml (per mu) to kill them steadily, and the effect is very good. Try to apply the medicine to the ground and weeds.

2) Changing bed seedlings with coniferous leaves, leaving bed seedlings: 30-100 ml of Huier per mu for forest, 1 bag of high-efficiency additives for forest, and 45 kg of water. The second time is 30 kg of water.

According to the situation of weeds, it can be refined and killed steadily, and 30-45 ml of fine grass can be added per mu. Note: The bed surface should be moist when spraying, so that the effect will be good.

3) The resistance of conifers to forest huil also varies. The resistance of cypress to Huil is less than that of pine (denoted by a sign of less than later); spruce, larch, pine, Korean pine; New seedlings, change bed seedlings, keep bed seedlings. Therefore, the dosage of cypress should be lower than that of pine, and the new seedlings should be lower than the seedlings with beds and the seedlings with new beds.

When the seedlings are diseased, they should not be used.

4) Some broad-leaved trees such as poplars and willows should be medicated before germination and leaf development.

Because herbicides are affected by soil and region, it is recommended to take a small dose for the first use, and then increase it after experience. You can also do a small-area test, and the effect can be seen in 7-10 days. When the seedlings (change the bed seedlings, leave the bed seedlings) germinate, the dosage should be taken in a small dose.

Notes:1Read the instructions carefully and operate in strict accordance with the instructions.

2.When using herbicides, it is advisable to choose windless weather. Pay attention to the characteristics of the herbicide. The medicine bag should be kept properly and should not be thrown away. Herbicides should be kept properly and should not be taken by mistake.

3.The sprayer should be cleaned in time after use, and it is best to use it specially.

4.For individual stubborn weeds, forest Huier + Jingwen can be used to kill or forest Huier + glyphosate compound directional control, with good effect.

5.For first-time users, a small area trial (2 square meters is sufficient) should be conducted first, and then a large area will be promoted after gaining experience. Yangling Green Protection.

For pine seedlings such as Huashan pine, larch, spruce, and pine sylvestris, weeding in nurseries and woodlands is a major job, and its production cost basically accounts for more than 50% of the production cost. Therefore, it is particularly important to choose a safe and efficient herbicide. In recent years, with the support of the forestry departments of Shaanxi, Ningxia, Gansu and other places, Yangling Green Protection Company has carried out an experimental study on the use of chemical herbicides to --- forest Huier and tending coniferous seedlings in young forests, and the results show that in the spring weeds have just begun to germinate, the single use of forest Huier can effectively close the weeds, and the validity period is more than 35 days.

The second trillion stops the weeds grow about 5cm, and the use of forest Huier + Jinghe grass gram or forest Huier + Jingwen killing, sealing and killing both, the effect is very good.
