Tongtianbao corn lodging-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 maize growth and yield formation, from the perspectives of improving the level of carbon and nitrogen metabolism, increasing the activity of stress protective enzymes (SOD, POD, CAT) and improving the utilization rate of nitrogen fertilizer, the compound of specific protein and plant growth substances was used to improve the process of maize growth and yield formation by adjusting the endogenous hormone levels in different growth stages and organs of maize, so as to realize the optimal regulation of maize morphological characteristics, physiological characteristics and yield formation, and achieve the effect of stable and high yield.

Efficacy:

Strong roots: Promote the growth of maize roots, increase the aerial roots by 65,438+0-2 layers, make the roots long and strong, and improve the fixation of the roots on the soil after forming huge roots, thus resisting root dropping. Root system has strong vitality and strong ability to absorb nutrients and water. Significantly improve the stress resistance of plants in the growth period.

Height reduction: the internode below the ear position becomes shorter, the internode above the ear position becomes longer, the stem becomes thicker, the stem wall becomes thicker, and the degree of lignification is high. The plant height is dwarfed, the ear position is reduced 15-30 cm, the center of gravity of maize plants moves down, and the roots resist lodging.

Strong source: weak seedlings promote strong, big seedlings dwarf, and build a neat and consistent high-yield population structure. The leaves are thick and dark green, chlorophyll increases, the functional period of leaves is prolonged, photosynthesis is enhanced, and the 1000-grain weight is increased, which promotes early maturity.

Increase storage: promote panicle growth, reduce bald tips, reduce grain moisture by 2-3% at harvest, improve commodity grain quality, and increase yield per mu by 100-300 kg.

Suggestion: This product is suitable for maize varieties with planting density above 3600 plants/mu or prone to lodging.

Usage: When there are 8-9 leaves of corn, the dosage is 30ml per mu, mixed with 15kg of water, and evenly sprayed on the leaves after 3 pm on sunny days.

Note: When mixed with other pesticides, TPB must be diluted with water before adding other pesticides. Direct mixing of raw materials is prohibited. Use with caution in severe drought.
