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

Embodiment

[0023] 1). Select high-quality seeds according to the types of grains to be sown. The specific selection requirements are: seeds with full grains, shriveled grains ≤ 5%, and germination rate ≥ 98%, that is, the quality of the selected seeds must meet the national standards. At the same time, a degradable film is prepared. The selection of the degradable film is characterized by a certain degree of firmness, no pollution, good water absorption, and a fast degradation cycle.

[0024] 2). The seeds selected in step 1) are soaked, dried, coated and sun-dried, specifically: the seeds are routinely soaked and then cleaned, and impurities such as grains and empty shells are removed, and the water is changed to continue soaking the seeds. Drain the excess water; dry the seeds until they are not sticky; then coat the seeds with a coating agent, preferably a coating agent (seeding agent) that can sterilize, kill insects, absorb moisture and retain water , the coating agent attached to t...

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...
