Tongtianbao soybean 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 soybean growth and yield formation, that is, temperature stress (high temperature and low temperature stress) and nutrient stress (poor soil), from the point of view of improving carbon and nitrogen metabolism, increasing the activity of stress protective enzymes (SOD, POD, CAT) and improving the utilization rate of nitrogen fertilizer, specific protein and plant growth substances were used to regulate the endogenous hormone levels in different growth stages and organs. Improve the growth and development process and yield formation process of soybean, so as to realize the optimal regulation of soybean morphological characteristics, physiological characteristics and yield formation, enhance stress resistance and saline-alkali tolerance, promote early maturity, improve quality, and achieve the effect of stable and high yield.

Efficacy:

Strong roots: establish a huge root system, enhance root activity and nutrient absorption capacity, and resist lodging. Promote nodule formation and enhance nitrogen fixation ability.

Strong stem: Dwarf plants, promote branching, make leaves thicker and bigger, and increase stem diameter, thus making plants strong.

Cold resistance: promote the formation of induced cold-resistant protein, increase chlorophyll content, strengthen plant nutrition, increase cell fluid concentration, improve quality, and enhance the ability of soybean to resist diseases, heavy crops and natural disasters such as environmental low temperature and cold. Generally, the yield of 10- 15% can be increased.

Prevention of flowering: increase the number of pods, promote pod growth, grain development and filling, promote early maturity and full beans, increase the weight of 100 seeds and increase production efficiently.

Improve the utilization rate of nitrogen fertilizer.

Spraying and effect description:

Soybean should be sprayed from branching to early flowering, and as far as possible in the branching period. The effect can be seen about 10 days after spraying. The leaves are thick green, the villi are thick and hard, and the stems are thick and hard, which can promote 1-3 multi-branching, and increase the number of flowers and pods per plant by 5-20. After 30 days, the number of 3 pods and 4 pods increased obviously, and the number of pods on the branches was large, and the pods were thick and insect-resistant. The taproot is stout, with a depth of 30-50 cm and 3-5 lateral roots. The fibrous roots are numerous and dense, and the nodules are large and full, with the number of 3- 10, and the nodule fluid is reddish brown. Strong nitrogen fixation ability. Generally, the yield of 10%- 15% can be increased.

Usage and dosage: 30mL water per mu 15-20 kg evenly sprayed from branches to early flowering, and evenly sprayed on leaves after 3 pm on sunny days. After spraying for 2 hours, the rainfall is halved, and after spraying for 4 hours, the rainfall has no effect on the effect.

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