The application of micro-fertilizer in vegetable production increased significantly, the ratio of production to investment was high, and the economic benefit was obvious. First, cucumber applies silicon fertilizer. According to studies, cucumbers can increase silicon production by about one-fold. Method is: In the flowering and fruiting period, apply 10 kg of calcium silicate per acre. A 1:100 solution can be wetted near the root, but do not touch the root directly. Can also be mixed in manure water application. Second, spray tomato calcium chloride. Calcium is effective in preventing tomato umbilical rot, but calcium is applied to the soil and it is easily fixed and the crop is difficult to absorb. At the same time, applying calcium will increase the pH of the soil and affect the absorption of elements such as boron and manganese. The use of calcium chloride with extra-root fertilizer can avoid the above phenomenon. The method was as follows: 15 days after the first flowering of the tomato, about 0.5 days of calcium chloride solution was sprayed on the opposite side of the tomato leaf every 10 days at about 5-6 pm. To wet it is appropriate. Third, cucumber, tomato foliar spray borax. Boron plays an important role in the development of floral organs and the transport of carbohydrates. China has used more oilseed rape and cotton in the past. According to experiments, the effect of preventing diseases, increasing yield, and improving quality is also evident in cucumbers and tomatoes. The application method and concentration are the same as those of calcium chloride described above. But do not mix with calcium chloride, application time should be staggered with 4-5 days, to prevent the high foliar concentration will affect the growth of the crop.
