What weeds in the countryside can cause crops to wither?

In the countryside, many things are very scarce compared to those in the city, but there are some things that are not lacking at all. These are all kinds of wildflowers and grasses, whether they are in the fields or in the mountains, they can be found everywhere. But the city is full of high-rise buildings, and there are few other green plants except for the uniform green trees on the roadside.

The weed that I want to introduce to you today, known as "plant vampires", often grow in the fields to harm crops, but I don't know that it is a precious Chinese medicinal material.

A weed in the countryside, known as a "plant vampire", scourges crops and makes people dislike, and I don't know if it is a precious herb. This kind of "plant vampire" is actually dodder seed, which is a precious Chinese medicinal material. It is a vine plant, its vine is very slender and small, and it is golden yellow, and it likes to be wrapped around trees or plants, and it looks like a golden ocean from a distance, which is very beautiful.

But don't be fooled by its appearance, this plant is actually a pest of grass, specifically pesting crops.

Why is it said to be a pest that harms crops? Because this plant cannot survive on its own, it is specially attached to various crops and fruit trees, absorbing and robbing the nutrients of fruits and trees, resulting in a decrease in the yield of crops and fruits, so it is also known as "plant vampires". The vitality of dodder is very vigorous, and a dodder seed can produce thousands of seeds, blowing with the wind, and then there will be seeds of dodder everywhere, in the spring, it will grow and sprout, continue to wrap around the grass and trees, to grab nutrients for its own development, don't look at the small and beautiful dodder seed, in fact, it can be "ruthless".

Cuscuta is a kind of temperature-loving plant, so in the south of our country a large number of survival, generally we go to the countryside as long as we see a piece of golden, wrapped in farmland or trees, then it is dodder seed. When we were children, we saw this plant and ripped off its vines and made them into garlands to wear on our heads to show off. In autumn, the dodder seeds will also wither, and at this time the dodder seeds can be much more difficult to handle, not only the branches are thicker, but also more difficult to tear off the trees after aging.

Dog's tail grass can cause crops to wither because it absorbs nutrients from crops and the like, causing crops to not grow properly.

Fireweed. This kind of grass looks very similar to crops, and is often mixed in it, absorbing the nutrients of crops, and it is not easy to get rid of them.

This weed is a common fireweed in the countryside. It damages the crops, and where it is, the crops will wither in patches, much to the annoyance of the farmers.

I have lived in the orchid room for a long time without smelling its fragrance, and I have lived in the abalone room for a long time without feeling its smell. Those who are close to Zhu are red, and those who are close to ink are black. Advocating virtue will make the soul noble, and following the crowd will become superficial.

Never get close to the fight, never ask about evil things. If you see too many strange things, you will not be surprised, but I feel normal. Therefore, we must not see, hear, speak, and act indecently.

In short, every word and deed, every action should be done in accordance with the teachings of the sages, that is, do not act if you are not virtuous. Some people say that the current Internet ** is a big sewage dye vat, full of monetary interests and erotic violence, poisoning the minds of many teenagers. Correction can only make up for small mistakes, and prevention can put an end to big mistakes, so we keep ourselves clean, stay away from the bad atmosphere of the Internet, and protect the pure land in our hearts.

The mind is a field, and the external envy of the world always affects our inner world, so it is natural for weeds to breed in the heart. If it grows, don't let the weeds grow and spread at will, and wait for the field to become barren and finally the grain will not be harvested. As the Zen master Shenxiu Bodhi said:

The body is a Bodhi tree, the heart is a mirror platform, always wipe diligently, do not cause dust, we should diligently remove the weeds in our hearts.

Wild grass and weeds, wildfires are inexhaustible, and the spring breeze blows and grows. The best way to get rid of weeds in the wilderness is to plant crops on them, so that the weeds have no room to survive and not have the slightest chance of rebirth. In the same way, the best way to keep the soul free of distractions is to occupy it with virtue.

Friends, let us listen to the teachings of the saints, learn the ancient and great spiritual culture and wisdom, sow the seeds of virtue in our hearts, and water them diligently with the sweat of the crystal. Let it grow real leaves, bloom good flowers, bear beautiful fruits, and let our hearts become a beautiful and fragrant garden!

Weeds are generally for crops, it grows in farmland or ridges, tenacious vitality, easy to reproduce, fast growth, and crops compete for nutrients, compete for living space, and spread pests and diseases, affect the growth and development of crops, if the prevention and control is not timely, it will reduce crop yield, quality, and bring great losses to agricultural production.

There was a farmer who happened to meet a rabbit who died on a tree stump when he was hoeing in the field, and he felt very lucky, so he didn't hoe the grass every day, just to wait for the rabbit to die on the stump again, but after a few months passed, he didn't wait for the rabbit, and the crops let the grass go out. It shows that when weeds are seriously harmed, the farmland can be harvested in one season. Many weeds are perennial plants, such as spiny cabbage, Siberian ice grass, etc., the root system is developed, the ability to resist the external harsh environment is stronger than crops, crops can freeze to death, but it can survive, its root tentacles stretch to the middle of the field, compete for nutrients, absorb nutrients strongly, grow fast, and also bully seedlings to shade, greatly affecting the growth and development of crops.

At the same time, it also spreads pests and diseases, and is the parasitic owner of many germs, viruses or pests, and the germs and insect eggs live and hibernate in weeds in winter, and when the temperature is suitable in spring, they will infect crops.

These 4 points are particularly harmful:

1.Seize the living space of crops, so that crops have nowhere to grow;

2.Weeds have well-developed root systems and strong ability to absorb water and fertilizer, and crops either die due to lack of water and fertilizer, or suffer from poor growth. At this stage, fertilization water is also a problem, without crop fertilizer and lack of water, most of it is absorbed by weeds;

3.Weeds are the hosts of some pests and diseases, which can transmit pests and diseases to crops;

4.Every year, weeding consumes a lot of labor, and a large number of herbicides are used to adversely affect soil searching.

The easiest way to deal with these weeds is: manual weeding, squatting in the ground to uproot the weeds by hand, but this method is the most tiring, if there is more land at home, it is necessary to use pesticides and herbicides, although this method is fast, but the poison will flow into the underground river with the rain, and the water is also a kind of pollution. This is the more common method and a very popular way.

It's going to die. Diquat fast, generally used as a conductive herbicide, can be quickly absorbed by green plant tissues, and quickly lose its activity after contact with soil. It is used for weeding in fields, orchards, non-arable land, before harvesting, etc., and can also be used as the stem and leaf drying of potatoes and sweet potatoes.

Diquat fast herbicide can be used to control soybean, sweet potato, cotton and other crops before harvest withering and defoliation.

How to use diquat fast.

1) No-tillage field weeding: used for weeding wheat and rape no-tillage planting after rice harvesting, 2 to 3 days before planting, 80 to 130 ml of 20% water agent per mu, 25 to 30 kg of water, spray weed stems and leaves.

2) Withering and defoliation: 6 to 8 days before the harvest of rice and wheat, at the early stage of cereal waxing, that is, when the green grains only account for 4% to 5%, pesticides can be applied to promote drying. 100 to 150 ml of 20% water solution per mu, a conventional spray on water.

150 to 200 ml of soybean and 200 ml of potato and 200 to 250 ml of potato per mu.

Precautions for the use of diquat fast:

1. Wear protective equipment when using this product and avoid inhaling the liquid. Do not eat or drink during the application period. Hands and face should be washed in time after application.

2. Check the sprayer before spraying to ensure that there is no leakage of the spraying instrument.

3. Within 7 days after application, do not graze or mow grass in the application area.

4. It is forbidden to clean pesticide application equipment in rivers and ponds and other waters to avoid causing harm to other organisms in the environment. Red-eyed bees and other natural enemies are prohibited in the release area. It is forbidden to discharge the wastewater from cleaning the pesticide application equipment into rivers and ponds and other water bodies for hail excavation.

Used containers should be disposed of properly, not for other purposes, and not discarded at will.

5. Do not apply pesticides when it is windy to avoid the mist drifting to crops or adjacent plots.

6. This product is harmful to bees, fish and other aquatic organisms and silkworms, and the impact on the surrounding bee colonies should be avoided during the application period, and it is forbidden to use it near the flowering period of flowering plants, silkworm rooms and mulberry gardens.

People have the impression that the herbicides used in agriculture to remove weeds will only remove weeds and will not damage crops. In fact, this view is one-sided. Among herbicides, there is a large category of herbicides that have no selectivity, which kill grass on sight, regardless of whether it is crops or grass.

There are also some herbicides, although they have the selectivity of killing weeds without harming crops, but not all grasses can be removed. Therefore, when using herbicides to control weeds, it must be strictly implemented according to the respective weeding characteristics of various herbicides. At the same time, from the perspective of protecting the environment, herbicides should also be used as little as possible.
