Calcium cyclamate (the leader of Quanfeng wheat) is a new type of plant growth regulator with high activity. It was developed by Japan Combined Chemical Industry Corporation in 1994 and successfully developed by Professor Zhang Jun of China Agricultural University in China. The acute toxicity of calcium tranexate in rats is more than 5000mg/kg. The environmental toxicology and environmental behavior tests show that calcium tranexate is slightly toxic, safe to the environment, with a half-life of 1 to 4 days in soil, and low residual risk. Calcium cyclamate is an inhibitor of gibberellin biosynthesis. It can control the growth of crops by inhibiting the biosynthesis of gibberellin.

In foreign countries, calcium cyclamate has been registered in wheat, barley, rice, peanut and apple, and has also been applied in the control of flower length and lawn length; China has obtained provisional registration on rice. Although calcium naphthenate has been registered on many crops, its use is too high, which restricts the promotion and application of the product. Professor Zhang Jun of China Agricultural University combined the new plant physiology principle with the application technology, and achieved success through the combination screening test in different physiological stages and products of rice. Calcium cyclamate regulates the growth and lodging resistance of rice, and the dosage per mu is only 1 gram. In 2010, Quanfeng Company cooperated with Professor Zhang Jun of China Agricultural University to develop new plant growth regulators, set up laboratories in Anyang Quanfeng Company, China Agricultural University and Sanya, Hainan, and carried out the growth control test of calcium cyclamate on wheat.

Although calcium naphthenate has been used in wheat, the amount of calcium naphthenate is too large, the use cost is too high, and the market promotion is not smooth. "Canopy", a product developed by BASF, contains 5% calcium tranexate and 30% methylphenidate?, 60-100g per mu; In a master's thesis in China, calcium cyclamate is used to control the growth of wheat. The amount of effective ingredients is more than 50g/mu, the cost is high, and it is not competitive in the market. Other growth inhibitors, such as paclobutrazol, uniconazole, chlormequat, and chlorhexidine, have problems such as large dosage, high residue, and affecting spike differentiation. Since 2010, under the leadership of Professor Zhang, we have studied the regulation of wheat growth by calcium cyclamate, and screened more than 240 formulations. In order to speed up the test progress and obtain more experimental data, we entered Sanya, Hainan, every November for three consecutive years, until the end of March of the next year, and carried out the test by taking advantage of Hainan's climate advantages. After the preliminary results were obtained, we promptly carried out the validation test in the main winter wheat production areas in the north, and then adjusted the composition according to the validation test results. The preliminary baking results of wheat in Sanya this year showed that the inhibition rate of wheat growth was 8% - 25%, the yield was as high as 30%, and the amount of calcium cyclamate per mu was reduced to about 2 grams. After the application of calcium cyclamate, wheat showed short and strong plants at seedling stage, dark green leaves, developed roots, large panicles and full grains, significantly increased yield, and was safe for wheat growth and development. This year, in cooperation with Hubei Provincial Agricultural Technology Station, it is planned to carry out a demonstration test of 100 mu square meters in Jianli, Zaoyang and Huaxian County, Huaxian County, laying a solid foundation for product promotion next year.

Wheat lodging is one of the main factors restricting the increase of yield. In order to avoid wheat lodging, dwarf varieties are generally selected for cultivation. High-root crops have higher yield, which is a consensus in breeding and cultivation. However, due to the problem of lodging, the planting area of high-stalk wheat varieties is very small. With several years of experiments, calcium cyclamate has entered the stage of application and popularization in wheat. We are going to change the name of this product to wheat navigator. The successful development of this product will bring a great change to China's wheat planting.
