Hi all, I'm the headline editor. Recently, the topic of straw returning to the field has caused quite a stir in the agricultural circle. Straw, once seen as a product of agricultural waste, is now being returned to the field in large quantities driven by environmental protection concepts. However, is straw returning really a "magic weapon" for sustainable agricultural development, as everyone thinks? Today, we will discuss it in depth.
Needless to say, the benefits of straw returning to the field can increase soil organic matter, improve soil structure, improve soil fertility, and provide a steady stream of power for agricultural production. Globally, more and more farmers are adopting the practice of returning straw to the field to achieve green and sustainable agriculture.
However, everything is too much. Excessive straw returning to the field may become a "stumbling block" to the sustainable development of agriculture.
First of all, the decomposition process of straw needs to consume nutrients such as nitrogen and phosphorus in the soil. If a large number of fields are returned to the field on a piece of land for many years in a row, it may lead to an imbalance of soil nutrients and affect the normal growth of crops.
Secondly, too much straw returning may make the soil too soft, affecting the permeability and drainage of the soil. Especially in the rainy season, the soil is prone to water accumulation, which leads to a lack of oxygen in the roots of crops and increases the risk of crop diseases.
In addition, straw returning can also cause pest and disease problems if it is not done properly. Some germs and pests can breed in the soil as the straw enters the soil, posing a threat to agricultural production.
So, how to balance the pros and cons of straw returning?
Scientific and reasonable straw returning method is the key. Farmers need to return to the field in an appropriate amount according to the actual situation of their own land, pay attention to the balance of soil nutrients, and avoid over-reliance on the short-term benefits brought by straw returning. At the same time, it is important to adopt the correct method of returning to the field. For example, the straw is crushed and evenly scattered on the ground, or the straw is fermented with other organic waste by composting, which can effectively reduce the breeding of germs and pests.
In addition, the government and relevant agencies also need to strengthen supervision and training. Through policy guidance and technical support, we will help farmers to return straw to the field correctly and scientifically, and improve their environmental awareness and sustainable production capacity. At the same time, we should strengthen investment in scientific research, develop more efficient and environmentally friendly straw treatment technology, and provide strong scientific and technological support for the sustainable development of agriculture.
To sum up, straw returning to the field is a double-edged sword. Appropriate and scientific return to land is conducive to the sustainable development of agriculture, but excessive return to land may bring a series of negative effects. As farmers, we must learn to adjust the strategy of returning to the land according to the actual situation of the land; as the government and relevant institutions, we must strengthen supervision and training, and promote scientific and environmentally friendly straw treatment methods; as ordinary consumers, we should also pay attention to the sustainability of agricultural production and choose green and environmentally friendly agricultural products. Only in this way can we give full play to the advantages of straw returning to the field and promote the green and sustainable development of agriculture.
