The mainland is a big agricultural country, but the cultivated land area is far lower than the world average while the agricultural population base is large, accounting for 8% of the world's arable land but feeding 19% of the population, agricultural production pressure is great. The mainland attaches great importance to the issue of food security, and in recent years, Document No. 1 of the Central Committee has always put forward important guidelines for the "three rural issues".
With the recent global extreme climate changes such as "El Niño" and "La Niña phenomenon", it has greatly affected the development of mainland agricultural production and seriously threatened mainland food security.
In the first half of 2022, natural disasters such as low temperature, hail, and floods caused crop damage to 3,618.9 thousand hectares, and in the second half of the year, the country continued to be hot, and the citrus industry suffered great losses due to four consecutive months of high temperature and drought in Hunan Province, resulting in nearly one-tenth of citrus deaths.
From August to October, Jiangsu late rice successively suffered high temperature in the breaking stage and low temperature in the filling stage, and the early pollination was insufficient to form empty grains, and the late key temperature was insufficient to form deflated grains, resulting in the loss of more than 10% of the yield of Jiangsu late maturing japonica rice.
According to statistics, the loss of crop yield caused by natural disasters caused by extreme weather has exceeded the yield loss caused by biological stress such as pests and diseases. Therefore, how to solve or reduce the impact of abiotic stress on crop yield, and reduce yield loss, is more important to ensure the food security of the continent and even the world in the future climate change. Studies have found that plant growth regulators can regulate the levels of endogenous hormones in crops and improve the resistance of crops to adversity.
Plant hormones: refers to trace organic substances naturally present in plants that have a significant effect on plant growth and development, also known as plant natural hormones or plant endogenous hormones. Its existence can affect and effectively regulate the growth and development of plants, including a series of plant life processes from cell growth and division to rooting, germination, flowering, fruiting, maturation and shedding.
Plant growth regulator: is after people understand the structure and mechanism of natural plant hormones, through artificial synthesis or plant extraction of substances with similar physiological and biological effects to plant hormones, used in agricultural production, in order to effectively regulate the growth process of crops, to achieve stable yield and increase yield, improve quality, enhance crop stress resistance and other purposes. Five major plant growth regulators were first discovered: biotin, gibberellin, cytokinins, abscisic acid, and ethylene.
With the continuous exploration and research of scientists, it has been found that brassica has the function of auxin, cytokinin, gibberellin and other plant growth regulators, so brassica is known as the "sixth largest plant growth regulator". Brassica has excellent performance in the stress resistance effect on crops, such as preventing spring cold of fruit trees, preserving flowers and fruits, preventing dry hot and dry wind of wheat, and promoting seedlings at low temperature.
New Chaoyang crystal type 14-hydroxybrassicin sterol is the world's only certified organic brassica, and it is also the only natural brassicinsterol, derived from rape pollen and its derivatives, which is affinity for plants, has fast effect, high activity and safety. Not only is it widely used in crops, but it can be used at various stages of growth and development of different crops, and no drug damage problems will occur when used for multiple times, which is incomparable with other brassica.
With the continuous in-depth research of natural brassica by New Chaoyang Company, after 4 technical upgrades, it has now ushered in the fifth generation of natural brassica-crystalline 14-hydroxybrassicin sterol. Through the screening of dominant crystal forms and successfully applied to the product, the activity is increased by 50%, the same day of use, the same day of effect, three days of visible effect to the naked eye, changing the previous brassica "effect is not obvious, not intuitive" problem. Since its listing in 1999, New Chaoyang Company has continuously made outstanding contributions to the development of mainland agriculture, and now with the frequent occurrence of extreme weather such as low temperature, high temperature, hail, flood and typhoon, New Chaoyang natural crystal form brassica will escort the food security of mainland China and the stable production and supply of important agricultural products.
