Water-soluble fertilizer is a new type of environmentally-friendly fertilizer that is easy to use, can be sprayed, sprayed, and used in conjunction with drip irrigation to increase fertilizer efficiency, save water for agriculture, reduce ecological pollution, improve crop quality, and reduce labor. obvious advantage. Due to the high price of water-soluble fertilizers, China has not yet widely spread.
With the intensification and large-scale development of China's agriculture, the water-saving facilities such as drip irrigation and sprinkler irrigation have expanded rapidly, and the application prospect of water-soluble fertilizers will be very broad.
Choose more efficient crops
The water-soluble fertilizer not only has relatively comprehensive nutrient elements, but also has a rapid fertilizer effect. After application, it can achieve the desired effect in a relatively short period of time. In addition, special fertilizers for different fertilizers can be produced according to the characteristics of fertilizers required for different crops, which are currently sold on the market. There are special water-soluble fertilizers for various crops such as vegetables, fruit trees, flowers, grain, cotton, and oil. However, the price of water-soluble fertilizers is much higher than that of solid fertilizers. Therefore, when selecting crops, it is best to target crops with higher yields, such as strawberries, vegetables and fruits, in order to obtain the best benefits; Lower, generally do not use water-soluble fertilizer (except potassium dihydrogen phosphate spraying on wheat).
At present, the practical application of water-soluble fertilizer production in China shows that this is also the case. The survey shows that the current application of water soluble fertilizers in China mainly focuses on greenhouse vegetable production bases, fruit tree production bases, and some flower and other planting areas, such as Liaoning, Hebei, Shandong, Xinjiang, Sichuan, Guangxi, Yunnan, and Hainan. Due to the short growth cycle of vegetables and high economic benefits, consumers have high demands on the quality of vegetables, and vegetable growers have higher requirements for fertilizers. Water-soluble fertilizers have become the fertilizer of choice for vegetable farmers. The quality vegetables grown can be sold at a good price. , Bringing high profits, so vegetables become the main consumer of water-soluble fertilizers. For field crops, because of their high cost, people are generally unwilling to invest or accept only traditional fertilizers.
Combining the characteristics of water-soluble fertilizers to master fertilization skills
Avoid direct flushing and adopt secondary dilution method. Since water-soluble fertilizers are different from general compound fertilizers, they should not be applied in accordance with conventional methods when they are applied, so as to avoid the occurrence of burning seedlings and roots caused by non-uniform fertilization; secondary dilution is not only beneficial to the uniform application of fertilizers. It can also increase fertilizer utilization.
Strictly control the amount of fertilizer. Water-soluble fertilizers have higher nutrient contents than conventional compound fertilizers and use less amount. Because of its fast-acting nature, it is difficult to retain in the soil for a long time. Therefore, it is necessary to strictly control the amount of fertilizer to avoid the loss of fertilizer, that is, to reduce the economic benefits of fertilization and fail to reach the goal of high yield, quality, and efficiency.
Use as much as possible or mix with non-alkaline pesticides. For example, in the absence of vegetables or poor root growth in vegetables, many farmers use more methods of spraying water-soluble fertilizer to ease. In this remind farmers friends, water-soluble fertilizer should be applied as far as possible alone or mixed with non-alkaline pesticides, in order to avoid precipitation of metal ions, resulting in leaf damage or injury.
Reasonable use and frequency
Generally speaking, water-soluble compound fertilizer formula is more reasonable, more nutrients, more targeted for the crop. However, unreasonable use in production can also result in waste of fertilizer and even negative effects.
Apply in small quantities. This is the most important principle for the application of water-soluble fertilizers, because this method not only meets the characteristics of uninterrupted nutrient absorption of plant roots, but also meets the characteristics of water-soluble nutrients that are easily lost. A small number of multiple applications can also greatly improve the utilization of water-soluble fertilizers.
Pay attention to nutrient balance. Water-soluble fertilizers are generally poured, sprayed, or mixed into water and applied with irrigation (drip irrigation, sprinkler irrigation). What needs to be reminded here is that when drip fertilization is used, the root growth is intensive and the quantity is large. At this time, the dependency on the supply of nutrients to the soil is reduced, and it is more dependent on the nutrients provided by drip irrigation. There is a higher demand for a reasonable ratio and concentration of nutrients. If the formula is not balanced, it will affect crop growth. In addition, water-soluble fertilizers should not be applied with conventional irrigation methods such as flood irrigation or flowing water irrigation to avoid fertilizer waste and uneven application.
Safe application to prevent burning of leaves and roots. Inappropriate application of water-soluble fertilizers, especially when applied together with sprinkler irrigation and micro-spraying, it is extremely prone to burning leaf and burning roots. The fundamental reason is that the fertilizer is too soluble. Therefore, in the deployment of fertilizer concentration is to be in strict accordance with the instructions of the concentration of deployment. However, due to different salt levels in different areas, the same concentration of burned leaves and roots occurred in individual areas. The safest method in production is to find the appropriate concentration of fertilizer in the region through fertilizer concentration tests.
Drip irrigation precautions
Water soluble fertilizers are applied along with drip irrigation and are the most common method in current production.
break off both ends. First drop water and add fertilizer after the pipeline is filled with water to avoid no fertilizer in the front section. Immediately after fertilization, drip water for 20 to 30 minutes and drain the remaining fertilizer from the pipeline (a conductivity meter can be used to monitor whether it is completely discharged); If the tube is not washed, moss, algae, and other low-grade plants or microorganisms may grow at the dripper, clogging the dripper and damaging the equipment.
Prevent the accumulation of salt on the surface. In greenhouses or greenhouses, long-term fertilization with drip irrigation can cause surface salt accumulation and affect root growth. Irrigation under the membrane can be used to inhibit salt migration to the surface.
Do it evenly. Pay attention to the uniformity of fertilization, drip fertilization in principle, the slower the better the fertilization. Especially for elements with poor mobility in the soil (such as phosphorus), extending the fertilization time can greatly improve the utilization of difficult-to-shift nutrients. In drip fertigation in the dry season, fertilization is recommended to be completed in 2 to 3 hours. In the absence of water in the soil, as soon as the uniformity is guaranteed, the sooner the better.
Avoid excessive irrigation. When irrigation is the main purpose of irrigation, it can reach the depth of root moisture. Different crop root depths are very different. You can use shovel to dig the soil at any time to know the depth of the root layer. Excessive irrigation not only wastes water, but also causes nutrient dialysis below the root layer, crops cannot be absorbed, and fertilizers are wasted; especially urea, nitrate nitrogen fertilizer (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate fertilizer, and water-soluble containing nitrate nitrogen Fertilizer) is extremely easy to lose with water.
With application. Water-soluble fertilizers are quick-acting fertilizers that can only be used as top dressings. Especially in conventional agricultural production, water-soluble fertilizers cannot replace other conventional fertilizers. Therefore, the practice of replacing other fertilizers with water-soluble fertilizers must not be adopted in agricultural production. The combination of basal fertilizers and top dressings, organic fertilizers and inorganic fertilizers, and combination of water-soluble fertilizers and conventional fertilizers must be used in order to reduce costs and provide various benefits. Fertilizer advantage.
