Sugarcane [scientific name] Saccharum officinarum Poaceae Sugarcane

Triacontanol

The middle and upper stems of plants with uniform size and no pests and diseases were selected, cut into single sprouts, dipped in 0.5-2.0mg/L solution for 30 hours and sown, which had a significant effect on the germination of sugarcane buds.

Gibberellic acid

Seed soaking with 100mg/L gibberellic acid solution for 24h can significantly promote sugarcane seed germination and seedling growth.

Indolebutyric acid

Soaking seeds with 50 mg/L indole butyric acid solution for 24 hours had a prominent effect on promoting seed germination and seedling growth.

6-BA

Soaking seeds with 10mg/L6-BA solution for 24h promoted the germination of sugarcane seeds and the growth of seedlings.

Sodium Nitrophenolate

Seed soaking with 9mg/L sodium nitrophenolate for 30min increased the final germination rate by 10% to 27% and the final tiller rate by 1% to 3% compared with the control, thus increasing the yield by 2% to 23%.

【2】Adjust sugarcane growth and increase quality

Gibberellic acid

From the end of tillering to the early stage of jointing, spray 25-30kg per mu with 40-50mg/L gibberellic acid solution, and then spray once every 15d, for a total of 2-3 times. Generally, for the first-plant sugarcane fields with good fertility, spraying 1-2 times is enough; for the fields with poor fertility and sugarcane planting for many years, it is appropriate to spray 3 times, which can adjust the physiological function of sugarcane and improve the carbon and nitrogen of the plant. ratio, improve photosynthesis efficiency, accelerate the growth of sugarcane stalks, and the effect of increasing sugar is remarkable. The edible stalk of sugarcane using gibberellic acid is increased by 10-15cm, the plant height is increased by more than 15%, the internode is increased by 18%-20%, and the yield is increased by 15%-20%. It was determined that the sugar content of sugarcane increased by about 5% compared with the control. At present, the use of gibberellic acid technology in sugarcane has been widely used. (Note: Gibberellic acid can promote the growth of stems and leaves, but increasing the concentration does not increase the growth effect, so the concentration should be controlled.)

Sodium Nitrophenolate

Spraying 12-24mg/L sodium nitrophenolate solution in seedling stage, tillering stage and elongation stage can increase tillering, promote precocious yield and increase sugar content.

Brassinolide

Use 0.01～0.04mg/L Brassinolide solution to spray twice continuously on the surface of sugarcane during the elongation period, which can make sugarcane leaves dark green, effective stem, plant height, stem diameter, single stem weight, growth rate, etc. All physiological indicators can be significantly improved, and the effect of increasing production and increasing sugar is remarkable.

Choline chloride

Spraying 500mg/L choline chloride liquid once in the tillering period and twice in the elongation period with an interval of 20 days can significantly increase the chlorophyll content of sugarcane, improve the photosynthetic rate, and affect the plant height, Stem thickness and sugar content in cane stems also increased.

Paclobutrazol

Within the concentration range of 60-200 mg/L, sugarcane tillers can be increased, leaf area expanded, growth accelerated, plants increased, and stem diameter increased, thereby increasing the actual yield of sugarcane by 1825-2334 kg per mu, with an increase of 26.02%-33.28%. In the concentration range of 100～150mg/L, paclobutrazol can increase the sugar cane sugar content, cane juice sucrose content, pure purity, etc., and reduce the reducing sugar. Beyond this concentration range, it will have a negative effect on sugarcane technological properties.

Trinexapac-ethyl and Brassinolide

In the early stage of tillering, spraying with 1g of active ingredients per mu after mixing with water can promote tillering, increase the number of effective stems, and increase the yield. In addition, 0.75mg of brassinolide is compounded to improve various indicators and yield.

Has a significant synergistic effect.
