Parasites in the soil can help rice grow healthily
The parasites in the soil often feed on the roots of rice, causing minor damage to rice. However, a French study showed that without them, plant-parasitic nematodes would be flooded, and the loss of rice would be even greater. According to a study released by the French Development Research Institute on the 23rd, the weight of a single plant can be reduced by more than 82% if it is attacked by plant-parasitic nematodes after 90 days of rice planting. In contrast, nematodes or other insects that live in the soil pose a much smaller threat to rice, and some rice can even grow normally. The institution’s biologists explained that plant-parasitic nematodes often invade temperate or tropical plants such as rice, sugar cane, and rubber trees. They invade the plant's roots and settle down, where their activities greatly hinder the plant roots from transporting nutrients to the upper part of the plant. People often use pesticides to kill these pests, but this increases the cost of planting and pollutes the environment. French biologists believe that insects that infest the soil also feed on the roots of plants, but they are not harmful. They can also stimulate the plants continuously, forcing them to improve their physical conditions and stimulate their immunity and resistance. Plant parasitic nematodes in the roots of plants have been greatly reduced, or they have appeared very late. Therefore, these parasitic insects in the soil can help rice and other plants to avoid greater losses, but also will not pollute the environment.
