Advantages of water-soluble fertilizer:
Compared with traditional superphosphate and granular compound fertilizer, water-soluble fertilizer has obvious advantages. It is a quick-acting fertilizer with good water solubility and no residue. It is completely soluble in water and can be directly absorbed and utilized by the roots and leaves of crops. The integration of water and fertilizer is realized through the simultaneous use of water and fertilizer, and its effective absorption rate is more than twice that of ordinary chemical fertilizer, reaching 80%-90%; But also has fast fertilizer efficiency and can meet the nutritional needs of high-yield crops in the rapid growth period. The water demand of drip irrigation system is only 30% of that of ordinary chemical fertilizer, and the fertilization operation can be almost labor-free, which greatly saves labor costs. More and more soil and fertilizer experts, agricultural technology experts, agricultural distributors and farmers have realized the importance of water-soluble fertilizers.
Selection of water-soluble fertilizer for production;
When choosing water-soluble fertilizers, it is best to choose brands registered in the Ministry of Agriculture, and it is best to choose special water-soluble fertilizers. Those enterprises with good agrochemical services and unique brand positioning have developed rapidly. For example, the water-soluble fertilizer of German Xinlu International Group has occupied about 50% of the water-soluble fertilizer market in Chinese mainland; At the same time, Germany's Xinlu International Group successfully passed the approval of CCTV's corporate channel and became a partner of CCTV, which is conducive to accelerating the pace of the company's independent brand building. At the award ceremony, the chairman of Germany Xinlu International Group received the plaque symbolizing authoritative certification from the relevant person in charge of CCTV Enterprise Channel, marking the official establishment of cooperative relationship between Germany Xinlu International Group and CCTV Enterprise Channel.
Methods and skills:
Nowadays, as a new type of fertilizer, water-soluble fertilizer is not only diverse in formula, but also very flexible in application method. Soil can be used for irrigation, so that the roots of plants can be fully exposed to fertilizers and breathe various nutrients. Can be sprayed on the leaves and enter the plants through the pores on the leaves, so as to improve the absorption and utilization rate of the fertilizer; Drip irrigation and soilless culture can also be used to save irrigation water and improve labor productivity. In the process of fertilization, it is necessary to combine the characteristics of water-soluble fertilizers and master certain fertilization skills in order to achieve the best results.
1. Avoid direct application of water-soluble fertilizer, and adopt secondary dilution method. Because water-soluble fertilizer is different from general compound fertilizer, farmers can't apply fertilizer according to conventional methods, resulting in uneven fertilization, burning seedlings, damaging roots and weak seedlings. Secondary dilution ensures uniform fertilization and improves fertilizer utilization rate.
2. Strictly control the amount of water-soluble fertilizer. Water-soluble fertilizer has higher nutrient content and less dosage than general compound fertilizer. Because of its quick effect, it is difficult to remain in the soil for a long time, so it is necessary to strictly control the amount of fertilization to avoid fertilizer loss, that is, to reduce the economic benefit of fertilization and achieve the goal of high yield, high quality and high efficiency.
3. Try to use it alone or mixed with non-alkaline pesticides. For example, when vegetables have element deficiency or poor root growth, many farmers use the method of spraying water-soluble fertilizer to alleviate it. Farmers are reminded that water-soluble fertilizers should be applied alone or mixed with non-alkaline pesticides as far as possible to avoid metal ion precipitation, causing fertilizer damage or phytotoxicity to leaves.
Precautions:
1. When using water-soluble fertilizer for the first time, please reserve a small plot for comparative test.
2. Foliar spraying should be carried out in the early morning or evening. If it rains within six hours after spraying, it needs to be sprayed again. Avoid mixing with strong alkali pesticides.
3. Keep it in a cool, dry and ventilated place.
4. Water-soluble fertilizer is instant, easy to absorb moisture, and may agglomerate, but it will not have any impact on product quality.
