Problems solved by technology

Sustained low temperature during the budding stage of rice will lead to a decrease in the ability of the root system to absorb water and mineral nutrients, damage to the cell membrane structure, imbalance of assimilate metabolism, and abnormal respiration, resulting in rotten seedlings, dead seedlings, reduced seedling rate, and delayed growth and development, thereby reducing yield
Therefore, cold damage and flooding lead to the "difficulty of full seedlings" of direct-d

Abstract

The invention relates to the technical field of agriculture. The invention provides a cold-resistant flooding-resistant seed coating agent for direct seeding rice. The cold-resistant flooding-resistant seed coating agent comprises a cold-resistant active component, a penetrant, an oxygen producer, an insecticidal bactericide, a trace element fertilizer, a plant growth regulator, an adhesive and anatural pigment. The invention also provides a preparation method of the cold-resistant flooding-resistant direct seeding rice seed coating agent. The preparation method comprises the following steps:accurately weighing the cold-resistant active component, the penetrant, the oxygen producer, the insecticidal bactericide, the trace element fertilizer and the plant growth regulator in proportion, conducting uniform stirring to obtain a mixture, grinding the mixture, weighing the adhesive and the natural pigment, adding the adhesive and the natural pigment into the mixture, conducting uniform stirring, performing quantitative packaging and carrying out hermetic storing. According to the invention, the cold resistance and flooding resistance of the direct seeding rice can be improved, seedling quality is improved, seedlings and roots are strengthened, the use amount of the agent is small, components are easy to obtain, cost is low, and the preparation method is simple.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a cold-resistant and flood-resistant seed coating agent for direct-seeding rice, a preparation method and a use method thereof. Background technique [0002] Direct-seeding rice is a primitive cultivation method. Because of its labor-saving operation, high yield, short growth period and good for large-scale production, the planting area has been expanding year by year, but direct-seeding rice production also faces many problems. Direct-directed rice is exposed in the field after sowing, and is vulnerable to environmental stress, especially low temperature and flooding in early spring, which seriously restrict the growth and development of rice. Every year, 3-5 billion kilograms of rice production is lost due to low temperature and chilling damage, and the planting area of ​​crops affected by flooding accounts for 12% of the world's total. [0003] Rice roots have develope...
