S-decoction (abscisic acid, S-ABA), like a vaccine, can activate the plant's own resistance or adaptation mechanism to adversity and improve the plant's The ability of drought resistance, cold resistance, disease resistance, etc., maintains the growth ability of crops under abnormal climate, soil and environmental conditions, and obtains a good harvest. Along with auxin, ethephon, gibberellin, and cytokinin, it ranks as the five major natural growth regulators for plants, and is an internationally recognized biological pesticide for plants to resist "adversity" disasters.
S-Yuhangsu has been widely used in agricultural production abroad, especially in the United States, Japan, Southeast Asia and other places, and has gradually been widely promoted in agricultural production in my country. In order to give farmers a better understanding of S-allotoxins, the author interviewed authoritative experts in the field of S-allotoxins who have been devoted to the research, development and promotion of plant regulators for many years-Professor George Walkerton, Washington State University, USA .
In the United States, S-allocin has become a must-use agent for the production of high-quality grapes; the grapes that use S-allocin in the United States can achieve high-quality results. At present, the application of S-allocin in the United States is mainly reflected in four aspects:
First, the new shoots are drawn and the flowering period is the same, and the full flowering period is about 10 days earlier. The method of use is from the water absorption period to the early stage of germination, using 1-2 ppm S-induction solution for root irrigation. It should be noted that from the water absorption period to the early stage of budding, the spraying treatment has no effect because the buds have not yet fallen off.
The second is to enhance the initial expansion of seeded grapes. The method of use is to spray the whole plant with 20 ppm S-pyramidin solution twice or irrigate the roots with 1-2 ppm S-pyramidin solution 10 to 15 days before the first flowering and at the end of the flowering period.
The third is to reduce the hardening of fruit stems in seedless cultivation, promote fruit hypertrophy, reduce fruit cracking, reduce grain drop, and promote coloring and early maturity. The method of use is to add 25 ppm S-ducine solution to the conventional treatment solution of gibberellin.
The fourth is to improve the poor coloring and high temperature obstacles during the high temperature period in summer, promote fruit hypertrophy again, advance the harvest period by 1 to 2 weeks, and improve fruit quality and taste. The method of use is when about 1/3 of the orchards in the orchard begin to color, use 1-2 ppm S-inducing antibiotic solution for root irrigation or use a special sprayer to prevent fruit powder from being soiled for fruit spraying. Regardless of whether there is a bag or no bag, the root irrigation treatment will not affect its effect, and there is no need to worry about the fruit surface being polluted. It should be noted that during fruit spraying, the promotion of coloring is faster, but the improvement of taste is slow, so the standard of harvesting should not only be marked by the degree of coloration, but after the sugar content is confirmed at the same time. reward. Negative effects such as quality degradation and unfavorable preservation.
In 2002, Tianjiao International Group of the United States invested and introduced the technical achievement project of fungal liquid submerged fermentation to produce S-inducing antibiotics, and established Tianjiao International Group (China) Co., Ltd. After years of hard work, it successfully developed a "high crop yield" suitable for China's soil conditions. ", “Nobel Fung” and other products.

　　With the continuous expansion of the planting area of ​​fresh table grapes in China in recent years and the improvement of the consumption level of Chinese residents year by year, domestic growers, distributors and consumers are now paying more attention to the safety, quality and taste of grapes. The functions of the vinaigrette in the process of grape cultivation make it a reality to produce green and safe grapes with excellent fruit shape and color and pure taste.
At present, the application of S-inducing antibiotics produced by Tianjiao International Group on grapes has been applied and verified in many provinces in China, and the feedback is very satisfactory. And through years of verification in many places, "more crops and more harvests" is more in line with the cultivation habits and medication habits of Chinese grapes.
In the United States, high-quality fruit can be produced with a reasonable combination of S-attractant and correct cultivation techniques, but there are still some differences in the cultivation conditions between China and the United States. First of all, the soil and climatic conditions in China are different from those in the United States. Therefore, when promoting the application of S-allotoxins from the United States in China, more consideration should be given to the actual situation in China and adjustments should not be made. The good news is that Tianjiao International Group Co., Ltd. has been devoted to the exploration and verification of the application of S-induced antibiotics on Chinese grapes for many years, and has now concluded a set of drug regimens suitable for the current situation of Chinese viticulture.
For example, when "harvest more crops" is irrigated on table grapes, it should be irrigated once 10 to 15 days before flowering, after fruit thinning and in the early stage of coloring (does not affect bagging), and the concentration of the drug is 1000 times diluted (every 1000 The liter of water contains 20 grams of over-harvest irrigation), and the amount of irrigation per plant = 1000 liters of water/number of plants. It can play the role of uniform coloring of fruit grains, increased sweetness, early market launch, and market preservation.
It is applied during the color change period of fresh table grapes (when 10% of the fruit is colored), and the concentration of the drug is 250-500 times diluted by spraying and dipping the fruit, which can promote coloring, market early, reduce acidity, increase sugar content, and improve cyanine. nutrient content and fruit quality, storage and transportation. At the same time, it can effectively avoid negative effects such as fruit drop, tree damage, fruit softening, quality decline, and unfavorable preservation.
