Can orchards be weeded by hand if herbicides are not used?

Orchard weeding is a more "headache" problem for growers, at present, most growers will choose to spray herbicides, but there will be two situations, one is that the weeding effect is not good, the other is afraid of pesticide damage to fruit trees, there are friends will have questions, if herbicides are not applied, what other ways can weeding in the orchard?

The little helper talked to some friends who planted orchards about this problem some time ago, in addition to herbicides, they commonly use the following 3 kinds, let's take a look:

1. Manual weeding.

This method is safe and effective, but it is time-consuming and laborious, for the orchard with a small planting area, if the orchard area is large, I believe that no one will choose this method, but as the earliest weeding measure, at the appropriate time, it is still worth using, especially some perennial weeds that are difficult to control, herbicides do not play a good role, and the effect of manual weeding is still OK.

2. Grass to control grass.

Using weeds to control weeds is also a good method, at present, many growers are using, some people will have doubts, the purpose is to weed, and now a lot of grass is planted, there are more weeds in the field.

This is not the case, because the grass planted is not an ordinary weed, the grass is a vegetatively reproduced weed, there is no need to worry about its large area of growth, at the same time, it does not need to control pests and diseases, and it does not grow tall, and at the same time, the absorption of water and nutrients in the field is also very small, and it will not affect the normal growth of fruit trees.

At present, the method has not been widely popularized, the specific details and operation methods, but also need to be explained in detail by professionals, interested friends, you can learn more.

3. a weeding truck.

About the weeding car, the little helper has not seen the real thing, just listened to some growers said, can cut the weeds in the orchard into grass, so that it does not affect the normal growth of fruit trees, generally can not be rooted, in addition, ** is not cheap, interested in this friends, you can search, detailed consultation dealers.

In addition, there are farmers who use black film to cover weeding, destroy the photosynthesis of weeds, and play the purpose of weeding, but there are also other farmers who react, and there is also a certain inhibitory effect on fruit trees.

The above are several methods of weeding in orchards without herbicides, you can choose according to the actual situation, if there is no suitable measure for yourself, or use herbicides.

If you don't use herbicides and are too tired to weed manually, you can now use a rotary tiller to weed, which saves time and effort, and all kinds of weeds can be wiped out in one net, and you can also choose the model that suits you.

Yes, if herbicides are not used, they can only be weed by hand, otherwise the growth of the fruit trees will be affected.

Hello, you can, but you need to follow the principle of pesticide mixing. Mixing principle: 1. After the two are mixed, no hydrolysis, alkaline hydrolysis, acidolysis or redox reaction will occur.

2. After the two are mixed, it will not affect the physical properties of the liquid medicine, that is, there will be no stratification, precipitation, emulsification, suspension rate reduction and other phenomena. 3. After the two are mixed, it will not increase toxicity and produce drug damage. 4. Organophosphorus and organosulfur pesticides cannot be mixed with copper-containing pesticides.

When is the herbicide sprayed with a good effect 1. If it is a season with low temperature such as winter, spring, and autumn, it is generally chosen to use the medicine from 10 am to 3 pm, and the temperature is more suitable at this time. 2. If it is a summer with high temperature, generally choose to take medicine before 9-10 am or after 4-5 pm. If the medicine is used at high temperature at noon, on the one hand, the water in the liquid medicine evaporates quickly, which is easy to lead to an increase in the concentration of the liquid medicine, resulting in the void tremor of the drug.

On the other hand, when the temperature is too high, the stomata on the foliar surface of weeds are closed, and the absorption rate of the liquid medicine decreases. 3. Spraying herbicides is generally carried out on sunny or cloudy days, requiring no wind or light breeze (wind below level 3), temperature above 10, and no dew on the leaf surface. Spring spraying time or according to the season to choose, such as spring, autumn weeding, the afternoon dark is relatively early and the weather temperature is low, in this case it is best to choose about ten o'clock in the morning to spray herbicide, at this time the dew in the field is basically gone, after the herbicide spraying is also conducive to the herbicide absorption and utilization.

Summer spraying and summer temperature is higher, the morning is relatively early, basically more than nine o'clock in the morning, the dew has basically dried, and seven o'clock in the afternoon before the gradual dew, it can be said that the morning cavity finch at 9 o'clock and the next Wu loss at four or five o'clock in the morning and noon spraying herbicides are a good choice. From the perspective of safety, it is basically very hot at 9 o'clock in the morning in summer, and the transpiration effect is relatively large, so if the safety of the herbicide itself cannot be fully guaranteed, it is more recommended to spray in the afternoon. Wheat field herbicide is a selective chemical agent, for the control of broad-leaved weeds such as pig seedlings, sowing Artemisia annua and camellia, etc., with 10% phenyiomilon 10 grams or 75% superstar 1 gram per mu, mixed with 40 kg of water evenly sprayed, the control effect can reach more than 95%.

For the control of grass weeds such as wild oats, knotweed and candle grass, 40-50 ml of huss or 20-25 ml of 3% shima per mu, and 50-100 ml of the product additives are mixed, mixed with 40 kg of water and sprayed evenly, and the control effect can reach more than 85%.

The first can be free-range, so that the livestock can eat weeds, and the second can be weeded manually, and the workload is relatively large.

Turning the soil frequently, you can also put a few chickens in the orchard, or put a few ducks can play an effective role in weeding.
