Grain seed direct sowing method

Abstract

The invention discloses a grain seed direct sowing method. The method comprises the following steps that quality seeds are selected, degradable thin film is prepared and made from a PBAT material; theselected seeds are soaked and aired and subjected to coating and seed drying treatment; the selected seeds regularly adhere to the degradable thin film according to the sowing technology of the seeds; the degradable thin film is regularly laid on a big field, and the degradable thin film laid on the big field is pressed by a heavy object, a plate-shaped object or a pressing roller and the like; under the premise of not influencing the sowing efficiency obviously and effectively ensuring reliable growth of seeds, scientific and accurate sowing is achieved, the starting points of seed groups are consistent, and the method is beneficial for saving the seeds, controlling planting cost and greatly increasing the yield.

Description

technical field [0001] The invention relates to agricultural sowing technology, in particular to a method for directional sowing rice. Background technique [0002] Rice is one of the main crops in my country. In recent years, due to the continuous decline in production efficiency and the excessive use of chemical fertilizers, pesticides, and herbicides, serious agricultural non-point source pollution has been caused. Moreover, the invasion of a large number of malignant weeds in rice fields and the continuous reduction of rural agricultural labor force have made the rice industry and rice food safety worse. Rice is a widely planted crop around the world. Eastern Asia is the largest production area. In recent years, countries have been facing similar problems such as frequent droughts, aging agricultural labor force, and erosion of farmland vicious weeds. [0003] There are two methods of sowing rice: direct seeding and transplanting. The direct broadcast method is to dire...

Problems solved by technology

The direct broadcast method is to directly sow dry seeds or soaked and accelerated germination seeds into the field according to the required sowing rate; compared with the transplanting method, the direct broadcast method saves two links of seedling raising and seedling transplanting, which is more labor-saving and labor-saving. At present, the planting area of ​​direct-directed rice in my country has an increasing trend year by year; however, there are the following problems when direct-directed rice: because the seeds are soaked, the wet seeds are prone to stick when sowing, resulting in uneven density of seedlings; On the soil surface, its roots are not firm, and it is easy to cause the plant to fall
