The common weeds in the rice fields cause great trouble to the growth of rice. To solve this problem, many farmers choose to use herbicides to control the growth of weeds. However, if herbicides are used in excess, they can cause serious damage to rice.
Let's analyze the causes of herbicide pesticide damage in paddy fields. Excessive consumption of herbicides is one of the most common causes of pesticide damage. The active ingredient in the herbicide is in contact with the rice leaves for too long and for too long, which can cause the rice leaves to mutate and even die. Therefore, when using herbicides, be sure to pay attention to the dosage and method of use, and apply the herbicide in strict accordance with the instructions.
What are the common weeds in rice fields?What kind of harm do these weeds have to rice?Weeds in rice fields are generally more moisture-tolerant and have strong vitality. For example, barnyard grass, heterosexual sedge, duck tongue grass, goldenrod, water triangular, double-spike paspalum, eyeweed, scorched grass, etc. These weeds compete with rice for nutrients and sunlight, causing poor growth, reduced yields, and the potential for pests and diseases.
If a rice field is oversprayed with herbicides, how can we remedy it?First of all, the pesticide damage can be reduced by spraying with water. Once excessive herbicide spraying is found, the spraying should be stopped immediately and the freshly applied rice should be sprayed with water to remove the residual herbicide on the leaf surface and reduce the possibility of the pesticide infiltrating into the rice leaves.
In addition to this, antidotes can also be used to help rice regain its growth. Injuries caused by excessive herbicide spraying in rice can be achieved by spraying 4000 times liquid brassinolide, 4000 times liquid gibberellin, 01% ferrous sulfate and other mixed liquids are sprayed on the rice to reduce the degree of pesticide damage as much as possible and promote the rapid recovery and growth of rice.
In addition, strengthening fertilizer and water management is also an important remedy. Rice is highly resistant to specialized herbicides in the field. Even if the leaves are damaged by external pesticides, as long as the heart leaves do not die, they still have the ability to continue to grow. Therefore, strengthening fertilizer and water management and promoting the growth of new leaves did not have much impact on rice as a whole.
In addition to the above methods, attention should also be paid to the prevention and control of rice diseases and pests. Red beans, like other legumes, need to be treated in a timely manner against pests such as powdery mildew, rust, aphids and spider mites. Only by maintaining good hygiene and ecological balance in the field can the harm of rice be minimized.
The main cause of herbicide damage in paddy fields is excessive herbicide use. In order to reduce the damage of paddy fields, on the one hand, it is necessary to control the amount and use of herbicides, and on the other hand, it is necessary to strengthen the prevention and control of weeds, diseases and pests. In addition, timely remedial measures, such as water spraying and the use of antidotes, as well as enhanced fertilizer and water management, can also help rice to recover growth as soon as possible. Maintaining field hygiene and ecological balance is also an important means to reduce the damage of rice.
From another point of view, weeds in rice fields also have their own reasons for survival. Although they are seen as the enemies of rice, they are also children of nature. If we can find a more coordinated way to manage weeds, we may be able to avoid the undesirable effects of herbicide use. This will undoubtedly require more research and practice to solve, but it is also part of our pursuit of sustainable agriculture.
Driven by agricultural modernization, farmers pay great attention to improving yields and efficiency, but sometimes they also ignore the balance of the agricultural ecological environment. The use of herbicides in rice fields is a short-term solution, but in the long term, we need more innovation and exploration to find more environmentally friendly and sustainable agricultural management.
Therefore, we should not only pay attention to the improvement of herbicide use technology in paddy fields, but also pay attention to the research and development of rice disease and pest control technology. Only by comprehensively using various means can we minimize the harm of rice fields and achieve sustainable agricultural development. The answer to this question is not simple, and there is no set standard answer. Each farmland is unique and needs to be considered based on factors such as local climate, soil and rice variety. Therefore, we need to continue to explore and summarize experience in order to better solve the problem caused by excessive herbicide use in rice fields.
