The multiple mysteries and new explorations of agricultural production

Agriculture, as the foundation industry for human survival and development, has always carried the heavy responsibility of ensuring food supply and maintaining ecological balance. In this vast field, the growth and development of crops is like an exquisite dance of life, and various growth conditions are the rhythm and melody of this dance. At the same time, their rich nutritional value injects endless vitality into human reproduction. In recent years, new achievements have continued to emerge in the field of agricultural science and technology, bringing the dawn of innovation to traditional agricultural production.
Light is like the "energy code" for photosynthesis of crops. It is an essential element for the healthy growth of chloroplasts and the smooth synthesis of chlorophyll. Within a certain range of light intensity, as the light increases, the efficiency of photosynthesis is significantly improved, and crops can efficiently convert light energy into chemical energy for their own growth and development. However, when the light intensity exceeds the light saturation point, the photosynthesis intensity will no longer increase, and even too strong light will destroy protoplasm, causing chlorophyll decomposition, stomata closure, and photosynthesis forced to weaken or even stop. When the light is too weak, the organic matter produced by crops is not even enough to make up for the consumption of respiration, and growth stagnates. For example, in a strong light environment, wheat plant height decreases, internodes shorten, leaves are thick and dark green, grains are full, and root systems are well developed; while in a weak light environment, internodes are elongated, plant height increases, root systems are poorly developed, and resistance is reduced.
The growth of crops has strict requirements on temperature, and most crops are suitable for growing in a temperature range of 15 degrees Celsius to 40 degrees Celsius. Temperature profoundly affects a series of physiological and biochemical processes of crops, such as photosynthesis, respiration, and transpiration. Taking photosynthesis as an example, photosynthesis increases at the beginning of temperature rise, but when the temperature exceeds the optimum temperature, the enzymes that catalyze dark reactions will gradually become passivated, denatured, or even destroyed, and the chloroplast structure will also be damaged, leading to a decrease in photosynthetic rate. Respiration is also affected by temperature. When the temperature rises, respiration increases, but at extremely high temperatures, the respiration rate will drop sharply after a short increase.
Water occupies a pivotal position in crops, accounting for about 70%-90% of their body weight. It is not only a key component of crops, but also an indispensable substance for crops to carry out photosynthesis, respiration, and absorb soil nutrients and other physiological activities. Reasonable water supply is an important guarantee for the normal growth and development of crops. When there is insufficient water, the young branches and leaves will wilt, seriously affecting growth and development; while too much water will cause the plants to grow too long, the roots will lack oxygen, respiration will be blocked, and it will be difficult to absorb nutrients, eventually causing the crops to wither and die.
Crops are not only the main source of human food, but also contain rich nutritional value. Cereal crops such as wheat, rice, and corn mainly provide the human body with rich starch, plant protein, and various vitamins. For example, wheat is rich in starch, protein, fat, minerals, and various vitamins. Its protein content varies depending on the growth environment. The protein content of wheat grains grown in continental arid climate zones can reach 14%-20%, and the gluten is strong and elastic, which is very suitable for making bread; while the protein content of wheat grains grown in humid environments is 8-10%, the grains are soft, and the gluten is poor. Legumes such as soybeans and broad beans are high-quality sources of protein and fat, which provide the human body with necessary nutrients. Tuber crops such as sweet potatoes and potatoes are rich in starch and vitamins. Taking sweet potatoes as an example, their average vitality index is 20.225 and their disease prevention index is 20.18, which has high nutritional value.
In today's world where agricultural science and technology is constantly developing, manganese dioxide catalysts, as an innovative means, are playing an important role in the field of pest control. Pests such as aphids and red spiders seriously threaten the growth of crops. Although the large-scale use of traditional chemical pesticides can have a certain control effect, it is easy to cause environmental pollution and excessive pesticide residues in agricultural products. Manganese dioxide catalysts can be used as insecticides to oxidize and destroy the pest epidermis. The principle is to use the characteristics of the catalyst to accelerate the chemical reaction related to the pest epidermis, so that the pest epidermis structure is damaged, thereby achieving the purpose of pest control. This method can not only effectively prevent and control common pests such as aphids and red spiders, but also greatly reduce the use of chemical pesticides, help the green and sustainable development of agriculture, and protect the ecological environment and agricultural product quality and safety while ensuring crop yields.
Agricultural production is a complex and delicate system. Light, temperature, water and other conditions precisely regulate the growth of crops, and the rich nutritional value of crops nourishes humans. The emergence of new agricultural technologies such as manganese dioxide catalysts has injected new vitality into agricultural development. In the future, with the continuous advancement of science and technology, we are expected to explore more innovative methods to promote agriculture in the direction of efficiency, greenness and sustainability, and create a better life for mankind.
