(1) scientific analysis, correct treatment, selection of high quality and low price, the effect of the ideal foliar fertilizer and regulator products. Treat the foliar fertilizers and conditioner products not to be rejected, and do not buy them at will. In the purchase, the main is to see whether the internal and external packaging is consistent, indicating whether the content is consistent with the internal content, "three licenses" that production license, product registration certificate, quality certificate is valid, is within the validity period. According to the trial and demonstration results of our Xiangfan Soil Fertilizer Station in recent years, among the more than 50 kinds of foliar fertilizers and regulators commonly found on the market, we use high-efficiency organic fertilizers, sprayed treasures, rare earths, high-efficiency fertilizers, and cuizhu brands. Plant growth regulators and other application effects are more ideal, and more than 10% production increase effect, stable and reliable, it is worth promoting. (2) Fertilizers cannot be replaced by foliar fertilizers or regulators. Excellent foliar fertilizers and regulators, although they have a relatively significant increase in production, and have a certain role in promoting the improvement of crop quality and stress resistance. However, they cannot be used as substitutes for fertilizers. They can only be "adding flowers to the cake" rather than "sending charcoal in the snow." They can only exert comprehensive effects on the basis of supporting measures for Liu production, such as adequate supply of fertilizer and water, and prevention of diseases and weeds. Therefore, the foliar fertilizer and NPK fertilizer should be taken into consideration. (3) Do not be greedy for more, beard and eyebrows, take advantage of efficiency. In the actual operation of some farmers' friends, they often prefer to use several kinds of foliar fertilizers or conditioners together. They think that the more effective the species is, the more effective it is. The other is spraying this kind of spray today and spraying it again tomorrow. This is a fallacy. From the current experimental demonstration results, the application of foliar fertilizers and regulators does not have an additive effect. Spraying even more will even affect each other's effects. In actual operation, one or two applications should be selected according to local conditions, avoiding unnecessary waste as much as possible. (4) Master the application method and control the application concentration. Foliar fertilizers and conditioner products are generally foliar sprays, and the use of dip seed dressings supplemented by spraying should be based on the optimum concentration of the species used, during the crop growth transition period, before 10 o'clock on a sunny day or in the afternoon. Afterwards, it is evenly sprayed on the leaves, young stems and ears of crops. Such as high efficiency should give birth to spirits should be 50 kg of water per 10ml; Cuizhu brand conditioner spray 50 kg per 10ml of water is the best concentration, and should not be arbitrarily increased the dose, arbitrarily increase the concentration. This will not only cause waste, but it will even have negative effects. Spraying requires sufficient dissolution, with the use of the distribution, and avoid strong evaporation of sunlight or rain leaching. (5) Be careful to save and prevent failure. Foliar fertilizers and conditioners are generally valid for less than 2 years and should therefore be used as much as possible during the period of validity. When not in use, it should be kept in a cool, dry and ventilated place.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.

At present, the application of foliar fertilizers and plant growth regulators is still very widespread in agricultural production. People often customarily call them "Jinhua" fertilizers, mainly because they can promote the growth and development of crops. Make the crops with good quality and high yield. However, in some places, some farmers have always been negative (refusing to use them) or ambiguous (with or without) attitudes, lack of scientific analysis and seeking truth from facts, thus affecting the use of foliar fertilizers and plant growth regulators. The promotion should be supplemented and the promotion and application of plant growth regulators. In fact, for all crops, the nutritional supplementation of foliar fertilizers and the control of plant growth regulators are effective. Many test results in various areas also show that as long as the correct application of foliar fertilizer and plant growth regulators, can generally increase crop yields, increase production rates up to 10% to 15%. However, when farmers' friends purchase and apply foliar fertilizers and plant growth regulators, they must pay attention to the following issues:
