Problems solved by technology

[0002] In the existing rice soaking agents, the control of rice diseases and insect pests, the provision of rice corresponding nutrient elements or the use of some growth regulators are considered, but some signal molecules needed in rice are not considered; and the current rice soaking agents neither consider The problem of rapid regreening of direct-directed rice after germination has not been focused on whether it can help rice germinate quickly on acidic soil; in addition, the current soaking agents are mostly powder or liquid bags, and there is no soaking agent in the form of effervescent tablets appear, its use is inconvenient, and its manufacturing cost is high

Embodiment 1

[0038] The invention provides a rice soaking agent, the rice soaking agent is an effervescent tablet suitable for sowing direct-seeded rice in acidic soil, which comprises: 0.08 parts of Bacillus thuringiensis wettable powder, 25% 0.08 parts of carbendazim wettable powder, 0.16 parts of disodium edetate, 5 parts of polyvinylpyrrolidone, 2.5 parts of polyethylene glycol, 0.25 parts of sodium hydrosulfide, 18 parts of sodium carbonate, and 60 parts of tartaric acid.

[0039] The preparation process is as follows: the above-mentioned components are dried and powdered separately, then granulated and dried, mixed and moistened with absolute alcohol containing polyvinylpyrrolidone, then polyethylene glycol is added as a lubricant, and extruded into 1000 effervescent tablets are enough.

[0040] In this example, Zhongzheyou No. 1 was selected as the rice variety to be soaked, and 1 piece of effervescent tablet was put into 1 liter of water to dissolve first, and then Zhongzheyou No. ...

Embodiment 2

[0044] The only difference between this example and Example 1 is that the rice seed soaking agent is an effervescent tablet, which includes: 0.12 parts of 10% imidacloprid wettable powder, 25% carbendazim 0.12 parts of wet powder, 0.24 parts of disodium edetate, 10 parts of gum arabic, 5 parts of polyethylene glycol, 15 parts of sodium nitroprusside, 25 parts of potassium bicarbonate, 70 parts of malic acid.

[0045] According to statistics, after sowing, as shown in Table 1, the germination rate of the control group is 81%, and the germination rate of the soaking group is 95%. It can be seen that the effervescent tablet soaking agent of the present invention can significantly improve the direct-directed rice in acidic soil. germination rate in . At the same time, the chlorophyll content of the shoot was measured three days after germination, and it was found that the chlorophyll content of the control group was 0.43, and that of the soaking group was 0.65. Thus, it is illust...

Embodiment 3

[0047] The only difference between this example and Example 1 is that the rice seed soaking agent is an effervescent tablet, which includes: 10% imidacloprid wettable powder + 20% acetamiprid soluble powder for supply 0.1 part, 0.1 part of 25% carbendazim wettable powder, 0.2 part of disodium edetate, 7 parts of paraffin, 3.5 parts of polyethylene glycol, 8 parts of sodium nitroprusside + sodium hydrosulfide, magnesium carbonate + bicarbonate A total of 25 parts of salt, 70 parts of malic acid + citric acid.

[0048] According to statistics, after sowing, as shown in Table 1, the germination rate of the control group is 79%, and the germination rate of the soaking group is 98%. This shows that the effervescent tablet soaking agent of the present invention can significantly improve the direct-directed rice in acidic soil. germination rate in . At the same time, the chlorophyll content of the shoot was measured three days after germination, and it was found that the chlorophyll...

Abstract

The invention relates to a rice seed soaking agent. The rice seed soaking agent is an effervescent tablet, and comprises the following components in parts by weight: 0.08-0.12 part of an insecticide,0.08-0.12 part of a bactericide, 0.16-0.24 part of a chelating agent, 5-10 parts of an adhesive, 2.5-5 parts of a lubricant and 0.25-15 parts of a signal molecular donor. The seed soaking agent is designed into an effervescent tablet form, and thus is easy to carry, and the effective components rapidly exert functions after water is added. Meanwhile, the signal molecule donor is added into the seed soaking agent, so that the growth of rice can be promoted.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a rice seed soaking agent. Background technique [0002] In the existing rice soaking agents, the control of rice diseases and insect pests, the provision of rice corresponding nutrient elements, or the use of some growth regulators are considered, but some signal molecules needed in rice are not considered; and the current rice soaking agents neither consider The problem of rapid regreening of direct-directed rice after germination has not been focused on whether it can help rice germinate quickly on acidic soil; in addition, the current soaking agents are mostly powder or liquid bags, and there is no soaking agent in the form of effervescent tablets Occurs, it is inconvenient to use, and the manufacturing cost is high. Contents of the invention [0003] Aiming at the above-mentioned technical problems in the prior art, the present invention provides a rice seed soak...
