In rural areas, sweet potatoes are an important food crop, however, many farmers often encounter problems when growing sweet potatoes, that is, sweet potatoes are not high-yielding, poor quality, and even insect pests. The reason is not just the poor selection or management of the land, but also the possible problems with the fertilization of the grower. The quality and application of fertilizers used in the growth of sweet potatoes have a direct impact on yield and quality.
Sweet potato fields are infested with insects, and many people mistakenly attribute them to soil quality or location. However, in fact, it has a strong relationship with whether growers use raw manure when fertilizing. Raw manure, i.e. animal manure that has not been fermented, can contain various eggs, germs and harmful bacteria. The smell of raw manure attracts a large number of bugs, including pests in sweet potato fields. Therefore, when fertilizing, we should avoid using raw manure that has not been fermented so as not to attract more pests.
Chicken manure is often used as an organic fertilizer in agricultural production, but we also need to be cautious when it comes to sweet potato cultivation. Although chicken manure is fermented, it is irritating in nature and contains high levels of ammonia nitrogen, which may adversely affect the growth of sweet potatoes. Too much ammonia nitrogen can cause the inactivation of microorganisms in the soil, affecting the ecological balance of the soil and making sweet potatoes more vulnerable to pests. Therefore, when applying chicken manure, we need to use it with caution, or mix and adjust it appropriately when using it to ensure that its use is within a controllable range and avoid negative effects on sweet potatoes.
Chemical fertilizers have some effect in improving soil fertility and promoting the growth of sweet potatoes, but excessive use may have adverse effects on sweet potatoes. Excessive nitrogen fertilizer can easily cause sweet potato plants to grow too luxuriantly, making them easier targets for pests. Therefore, when using chemical fertilizers, they should be applied reasonably according to the soil texture and the growth stage of sweet potatoes, and over-fertilization should be avoided. Too much chemical fertilizer not only increases the cost of cultivation, but can also adversely affect the environment.
Compared to excess raw manure and chemical fertilizers, organic fertilizers are more suitable for the cultivation of sweet potatoes. Organic fertilizer is rich in organic matter, which can improve soil structure, improve the water and fertilizer retention capacity of the soil, and help improve the resistance of sweet potatoes to diseases and pests. However, when choosing an organic fertilizer, it is also necessary to choose carefully to ensure that its composition and quality meet the growth needs of sweet potatoes.
Piling up waste containing harmful substances, such as waste plastics, chemical containers, etc., near sweet potato fields will release harmful gases and have a negative impact on the growth of sweet potatoes. At the same time, these wastes can become a hiding place for pests, increasing the chance of insect infestations. Therefore, keeping the area around the sweet potato field clean and avoiding stacking harmful substances can help reduce the occurrence of insect infestations.
In the cultivation of sweet potatoes, scientific and reasonable fertilization is one of the keys to ensure the healthy growth of sweet potatoes and improve the yield and quality. By avoiding the use of raw manure, using chicken manure carefully, avoiding excessive use of chemical fertilizers, not using waste containing harmful substances, and choosing the right organic fertilizer, the pest pressure of sweet potatoes can be effectively reduced, the yield can be increased, and better economic benefits can be brought to farmers. Therefore, in the cultivation of sweet potatoes, scientific and reasonable fertilization is an important link that farmers need to take seriously.
In addition, we learned that environmental sanitation near farmland is also closely related to the growth status of crops. Waste from the accumulation of hazardous substances can lead to the release of harmful gases, which in turn can have a negative impact on crops. This suggests that we should pay attention to the improvement of the surrounding environment of farmland, maintain cleanliness and hygiene, prevent waste pollution of crops and soil, and create a healthier growth environment for agriculture.
In future agricultural production, we need to rely more on scientific and technological means and use advanced technological means to guide agricultural production. The popularization of agricultural expertise and the application of scientific and technological means will help farmers better understand the soil conditions and crop growth conditions, so as to formulate more scientific and reasonable fertilization programs. The continuous development of agricultural science and technology will become an important support for improving agricultural efficiency and ensuring food security.
Finally, we feel the importance of environmental protection in agriculture. Choosing the right fertilizer and scientific fertilization can not only increase yields, but also reduce environmental pollution. Agricultural production and the ecological environment are not antagonistic, but can complement each other. By reducing the dependence on chemical pesticides and chemical fertilizers, the sustainable development of agriculture is not only conducive to the improvement of farmers' economic benefits, but also helps to maintain the ecological balance and protect the ecological environment of farmland.
In this era of continuous development, we should pay attention to learning from Xi and drawing on new agricultural scientific and technological achievements to improve the intelligent level of agricultural production. At the same time, it is necessary to strengthen the training of peasants, improve their understanding of scientific fertilization, enable them to make better use of scientific and technological means in actual operation, gradually get rid of the dependence on traditional agriculture, and realize the modern development of agriculture.
The selection and application of fertilizer in sweet potato cultivation provides us with rich experience and enlightenment. In the future development of agriculture, we need to pay more attention to scientific and technological innovation, strengthen the intelligent level of agricultural production, improve the cognitive level of farmers' scientific fertilization, and realize the sustainable development of agriculture. By continuously summing up experience and strengthening scientific and technological support, we are confident that we will usher in a better tomorrow in the field of agriculture.
