Tongtianbao wheat stress-resistant yield-increasing agent

Tongtianbao is a national invention patent product of Institute of Crop Science, Chinese Academy of Agricultural Sciences. Aiming at the limiting factors in the process of wheat growth, development and yield formation, that is, temperature stress (high temperature and low temperature stress) and nutrient stress (poor soil), from the perspective of improving carbon and nitrogen metabolism level, increasing the activity of stress protective enzymes (SOD, POD, CAT) and improving the utilization rate of nitrogen fertilizer, the growth and yield formation process of wheat was improved by adjusting the endogenous hormone levels in different growth stages and organs of wheat by using the combination of specific protein and plant growth substances. After several years of popularization and demonstration, after three times of comprehensive chemical control, the wheat yield increased by 200-300 kg, and the wheat yield in some planting areas exceeded the local high-yield record.

Special for cold resistance before winter

Promote tillering, resist cold, turn green quickly and have high seedling rate.

Spraying at the 3-5 leaf stage before winter can significantly improve the activity of protective enzymes, increase the sugar content of wheat tillers, induce the production of cold-resistant proteins, and enhance the cold resistance of plants. The root system has strong vitality, and 2-3 tillers are added before winter, and the number of effective spikes at harvest is increased by 20-30%.

Special for jointing stage

Lodging resistance of booting, strong roots and strong stems

Spraying at jointing and booting stage can promote the strength and uniformity of stems and enhance the lodging resistance. Promote large panicle breeding, promote effective tillers to become panicles, accelerate ineffective tillers to wither, and improve nutrient utilization rate.

Shaping ideal plant type and improving light distribution in field.

Special for grouting period

Strong disease resistance, fast filling, full seeds, strong resistance to dry and hot wind and high yield.

Spraying at grain filling stage can significantly increase chlorophyll content, enhance photosynthesis, delay plant senescence and resist dry-hot wind. The number of grains per panicle increased by 10-20%, and the 1000-grain weight increased by 1-2g.

Usage: 30ml/ mu each time, mixed with 15-20 kg water, and sprayed evenly (the rainfall is halved within 2 hours, and the rainfall effect will not be affected after 4 hours).

Note: If it is mixed with other pesticides, TPB must be diluted with water before adding other pesticides. Direct mixing of raw materials is prohibited. However, when diluted and mixed with herbicides, the weeding effect can be enhanced and the phytotoxicity to crops can be reduced. Diluted and mixed with bactericide can enhance the efficacy.
