Corn and peanuts are short and strong, so does rice also need to be short and strong?
The answer is yes. Dwarf and strong agent is an antagonist of gibberellin. As a plant growth regulator, it can effectively control plant overgrowth, promote reproductive growth, shorten plant internodes, grow short, strong, thick, well-developed root system, and resist lodging. At the same time, it also deepens color, thickens leaves, increases chlorophyll content and photosynthesis, so as to improve crop yield and quality.
When is the right time?
The dwarf agent can enter the interior of the plant through leaves, stems, roots and seeds, so it can be mixed, sprayed and irrigated. However, the purpose of application is different, and the application time is also different. Here are two commonly used examples.
One is anti-lodging.
In general, the use of dwarf agent in rice is to resist lodging, the principle of lodging resistance is to control the elongation of the first and second nodes of rice base, thicken the stem and improve the ability of lodging resistance. therefore, application after jointing can not play the role of lodging resistance. Therefore, the application time is particularly important, the effect is the best when the first section of rice begins to elongate, no later than the early stage of jointing, the dosage: diluting 300 times with 50% water agent, spraying the whole plant, it can be dwarfed, resistant to lodging, make the grain full and increase the yield.
The second is to improve resistance.
To improve the resistance, the seeds can be mixed with dwarf agent or soaked in 30 times solution for about 10 hours. the main principle is to promote the development of root system, increase the content of chlorophyll and improve the resistance of rice.
Note: when using in the land with better water and fertilizer conditions, pay attention to read the instructions before use and control the drug concentration.
The above comes from promoting agriculture through science.
