Abstract

The invention belongs to the technical field of rice planting, and particularly relates to a regulating agent for promoting flood-resistant growth of direct seeding rice and a using method thereof.The growth regulating agent is prepared from, by weight, hydroxy propyl cellulose, sodium alginate, starch, gibberellin, hydroxymethyl chitosan, inorganic salt, a bactericide, an insecticide, an oxygen producer and water; the use method comprises the following steps: mixing gibberellin, hydroxymethyl chitosan, inorganic salt, bactericide and insecticide to form a mixture A; mixing hydroxy propyl cellulose, sodium alginate and starch to form a mixture B, and then adding the mixture A to obtain the growth regulating agent; before sowing, direct sowing rice seeds are completely soaked in a growth regulating agent solution. Hydroxyl forms hydrogen bonds to form a mixed film with good performance, the slow release function is improved, the permeability of the film is improved, then rice seeds can be prevented from being in a long-term waterflooding state, rice growth is promoted, the stress resistance of crops is improved, and the product yield can be increased.

Description

technical field

[0001] The invention relates to the technical field of rice planting, in particular to a flood-tolerant growth-promoting regulator for direct seeding rice and a method for using the same. Background technique

[0002] Rice is one of the important food crops in China. Rice direct seeding refers to a cultivation method in which seeds are directly sown in the field without raising seedlings and transplanting. The advantages of labor, labor saving, seedling saving and high efficiency can realize the mechanization and light weight of rice planting, and become the first choice for farmers who lack labor.

[0003] In the wet direct seeding cultivation mode commonly used in my country, the construction of a field water layer through the seedling stage of direct seeding rice can achieve a good effect of closing the field and preventing weeds, but it often leads to the long-term flooding of rice seeds, and the flooded conditions when the seeds germinate. , the rate of ...
