Rice grows and kills insects in vegetable fields

When the rice in other parts of Foshan has not yet started to boot, the experimental mid-late rice field in Tangbian village of Shihai, South China Sea, has already reached the harvesting season. “Originally, when growing melons in the fields, they were always long bugs and they used drugs to kill them. After a season of mid-late rice experiments this year, the rice grew surprisingly well.” Yesterday, farmers standing in a golden rice paddy Tang Shu, happy laughter was quickly overwhelmed by the sound of the booming and booming harvester. “It is not a mistake to grow vegetables and rice, and there is no need to eat!” This is a summary of the image of the Shishan farmers' experiments on the “middle-late rice and cum farming system reform in one season” experiment. This year, the Rice Research Institute of the Provincial Academy of Agricultural Sciences cooperated with Nanhai to start a pilot demonstration project of mid-late rice in Shishan, effectively preventing pests and rationally using cultivated land, and at the same time safeguarding grain production. Land consolidation has puzzled agriculture In recent years, the adjustment of crop structure in the South China Sea has been particularly rapid, and rice and other food crops with low economic benefits have been greatly reduced, while the cultivation of high value crops such as vegetables and flowers has increased substantially. Due to the long-term continuous cultivation of the same vegetable species or the same type of vegetables, the farmers are forcing long-term overload production of vegetable fields, and the negative effects are becoming heavier. For example, some soils appear acidified and hardened, some of the soils are seriously deficient, soil fertility is reduced, and the soil is toxic. Increase in harmful substances. In addition, the high-temperature, high-humidity climate in Foshan from June to the end of September each year is not suitable for growing vegetables such as melons, solanaceous vegetables, and leafy vegetables. This not only greatly plagues the production of local vegetables, but also has a serious impact on the sustainable development of agriculture. The experts said that the experimental field adopts the “vegetable-middle rice-vegetable” planting model. The specific planting period is from January to May, and the vegetables are planted in June. Planting rice in September and planting vegetables in October and December. From June to September, due to the high temperature, rainy and strong light weather, the impact of planting of vegetable crops was greatly disturbed. During this period of time, rice was transplanted, crop structure can be reasonably arranged, crop rotation can be achieved, and farmland quality and production capacity can be adjusted to achieve agricultural production. Virtuous circle. Especially when the fields are filled with water, many pests and diseases, especially underground insects, are drowned and the pests and diseases are well controlled. Authoritative experts of the province believe that the rotation of vegetables and rice is a new pattern of rice field cultivation explored in the adjustment of agricultural structure in the economically developed areas of Guangdong Province. This model has improved the ecological environment, increased the acreage of grain, and improved the comprehensive benefits of paddy fields. It is a pioneering practice in the traditional rice cultivation system in Guangdong Province. It is important for the reform of the planting system after the traditional rice fields in Guangdong are adjusted to horticultural crops such as vegetables. Realistic guidance significance.
