First, the application of silicon fertilizer to cucumber.
According to research, the application of silicon fertilizer to cucumber can increase production by about 1 time. The method is as follows: 10 kg of calcium silicate per acre is applied during the flowering fruit setting period. The 1:100 aqueous solution can be wetted near the root, but not directly in contact with the root. It can also be mixed in manure.
Second, the tomato leaves are sprayed with calcium chloride.
Calcium is effective in preventing umbilical rot of tomato, but calcium is applied to the soil and is easily fixed, and the crop is difficult to absorb. At the same time, after applying calcium, the pH of the soil will increase, which will affect the absorption of elements such as boron and manganese. The use of calcium chloride with root dressing can avoid the above phenomenon. The method is as follows: 15 days after the first flowering of the tomato, sprayed on the opposite side of the tomato leaf with a 0.5% aqueous solution of calcium chloride at about 5-6 pm every 10 days or so. It is better to spray wet.
Third, cucumber and tomato leaves spray borax.
Boron plays an important role in the development of floral organs and the transport of carbohydrates. In the past, China has applied more on rapeseed and cotton. According to the test, it is also obvious to prevent disease, increase yield and improve quality on cucumber and tomato. The application method and concentration are the same as those of the above calcium chloride. However, do not mix with calcium chloride, the application time should be staggered for 4-5 days, to prevent the leaf surface concentration is too high will affect the growth of crops.
