Abstract
The invention discloses a seed coating agent specially used for direct seeding rice, which is characterized in that the seed coating agent mainly contains the following ingredients by weight: 2 to 8 percent of super absorbent resin, 1 to 5 percent of oxygenates, 0.1 to 0.5 percent of sparrow and rat destruction agent , 0.5 to 2 percent of bactericide, 0.5 to 2 percent of pesticide, 0.02 to 0.2 percent of plant growth regulator, 3 to 10 percent of trace element fertilizer and the margin is special type mineral clay. The powder raw materials are crushed to more then 100 meshes and are mixed evenly, the mixture is coated on the surfaces of rice seeds by a seed-coating method for direct sowing, thus clay sacculus integrating 'a small water reservoir, a small oxygen reservoir, a small drug storage and a small fertilizer storage' are formed around the rice seeds and at the roots of seedlings; the seed coating agent has the effects of preserving and providing water, ventilating and providing oxygen, promoting seedling emergency, preventing diseases and killing pests, preventing mice and destructing sparrows, strengthening seedlings and roots and increasing production. The seed coating agent is also characterized by low dosage, low cost, simple and convenient operation, and the like, thereby being applicable to coating rice seeds which are directly sowed both on flooded paddy fields and dry paddy fields.
Description
technical field [0001] The invention relates to a preparation for treating crop seeds, in particular to a seed treatment agent for dressing rice seeds when direct-seeding rice is sown. Background technique [0002] With the development of rice cultivation technology, the improvement of rural economy, and the change of labor force structure, rice direct seeding is popular among farmers because of its simplicity and cost-saving features, and its application area is expanding rapidly. However, the output of direct-directed rice is unstable, which constitutes a prominent problem in current rice production. The key to the stable production of direct-directed rice is the emergence of seedlings. The main constraints are: first, the depth of the dry direct-directed seeds into the soil is different, and the degree of water absorption of the rice seeds is different, resulting in incomplete and uneven emergence, and severe bakanae disease, and the seedlings are slender and thin; It is...
