I. Why are medium-element water-soluble fertilizers used for fertilizing fruit trees? 1. The soil is not lacking in calcium fertilizer; what is lacking is mobile ionic calcium, so when choosing fertilizer, be sure to choose a calcium fertilizer that dissolves quickly in water. Research shows that crops such as ginger, watermelon, chili pepper, eggplant, tomato, and grape absorb calcium far...
With the rapid development of science and technology, there are more and more types of foliar fertilizers on the market. Most contain nutrient elements essential to crops and can prevent various physiological diseases caused by nutrient deficiencies in crops. Some foliar fertilizers contain humic acid, growth aids, and physiologically active substances, and have effects such as promoting crop growth and enhancing stress resistance. Correct use of foliar fertilizer has a certain effect on improving crop quality and increasing yield. However, most foliar fertilizers do not contain fungicides or insecticides, and have no direct control effect on infectious diseases caused by fungi, bacteria, or viruses. However, in order to promote sales and obtain higher economic benefits, some foliar fertilizer manufacturers and dealers work hard on wording, describing product effects as omnipotent, such as being able to effectively control damping-off, rust, smut, soft rot, and Verticillium wilt; some product introductions say that spraying at different growth stages can prevent wheat powdery mildew, sheath blight, smut, and dwarf bunt, claiming control effects even better than some pesticides currently in use. Here, farmers are reminded that the use of foliar fertilizer should be targeted, and corresponding fungicides and insecticides should be selected to control crop diseases and insect pests. Never use foliar fertilizer as pesticide, so as to avoid losses.
