Water Soluble Fertilizer (WSF) is a multi-component fertilizer that can be completely dissolved in water. It can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high. The key point is that it can be applied to facility agriculture such as drip irrigation to achieve water and fertilizer integration, and achieve the efficiency of water saving and fertilizer saving.
Advantages of water soluble fertilizer:
The first reason is that the nutrients are all
Water-soluble fertilizer not only has a large amount of elements nitrogen, phosphorus, potassium, but also rich in medium and trace elements such as Molybdenum, which contains iron, manganese, zinc, copper, calcium, magnesium, boron, molybdenum, etc., and chelated trace elements are more easily Absorption conversion, in addition to active organic matter such as amino acids and humic acid (regulation of soil compaction). The general fertilizer is only a single element, and the long-term use will cause the problem of compaction and acid-base imbalance.
Reason two, provincial fertilizer
Conventional application of chemical fertilizers for an acre of land requires more than 40 kilograms, which is a bag, and it takes two people to operate very troublesome, and water-soluble fertilizer is only a fraction of that of chemical fertilizer. For example, 5 kilograms of German Moorish water soluble fertilizer can be applied to one acre of land. One person can quickly topdress.
Reason three, low price
A common chemical fertilizer bag is about 100 yuan, and the price of water-soluble fertilizer is similar to this. From the comparison of fertilizer efficiency and dosage, it is naturally beneficial to water-soluble fertilizer, and the investment cost is naturally reduced.
Reason four, no pollution
The long-term use of chemical fertilizers will cause different degrees of damage to the soil and the environment, and the water-soluble fertilizer itself is all the nutrients required by the plants, and there is no pollution problem in large quantities, and the humic acid component just mentioned can also improve the acid-base imbalance in the soil. The problem can be described as two things.
Reason five, development trend
In recent years, China has introduced a number of preferential policies and regulations on agriculture, such as supporting agricultural subsidies, agricultural machinery subsidies, and water and fertilizer integration policies introduced by the Central No.1 document, realizing large-scale land transfer and mechanized large-scale planting and fertilization management, etc. :
(1) Water resources, China is one of the countries with poor global freshwater resources. The problems of seasonal and industrial distribution of agriculture and regional water shortage are prominent. As a new type of environmentally friendly fertilizer, water-soluble fertilizer can be sprayed, applied and used in combination with drip irrigation to improve fertilizer utilization, save agricultural water, reduce ecological pollution, improve crop quality and reduce labor.
(2) Modern agriculture must be, traditional agriculture pays attention to slash-and-burn, modern agriculture pursues four goals of green, high efficiency (water and fertilizer integration), pollution-free, and increased production, and the timely emergence of water-soluble fertilizer just promotes rapid development. And the huge demand of the market.
(3) In the soil circulation, large-scale large-scale planting will inevitably require lower cost operation, and fertilization is one of the big problems. Reducing the cost of fertilization (dosage, labor) is a necessary condition for increasing the profit of the mu, and the previously described water-soluble The amount of fertilizer and the amount of labor and the amount of labor are well satisfied to meet these requirements, and the demand for natural water-soluble fertilizers will also rise.
Water soluble fertilizer use 诀çª:
Although the application of water-fertilizer integration technology to water-soluble fertilizers brings a lot of convenience to agricultural production, poor use can also bring disasters, and strict fertilization time and fertilizer dosage must be used.
Below, Xiaobian will bring you to understand some tips on using water and fertilizer.
Fertilization time:
When watering and fertilizing, the temperature of the water should be as close as possible to the ground temperature and temperature, and do not flood the water. Watering the greenhouse in winter, try to water in the morning; try to water in the afternoon or evening in summer. If you do not use a dropper, try to pour as little water as possible. Flooding of large water is easy to cause soil compaction, root respiration is blocked, affecting nutrient absorption, and it is easy to rotten roots and dead trees. Promoting "cultivation on the ridge" is conducive to high yield of crops.
Fertilizer dosage:
Only scientific fertilization can achieve the desired yield and quality. Scientific fertilization is not only about the distribution of the party, the quality, but also the scientific use. Generally speaking, terrestrial vegetables use 50% water soluble fertilizer, the amount of mu is about 5 kg, plus about 0.5 kg of water-soluble organic humic acid, amino acid, chitin, etc., in addition to increasing nitrogen, phosphorus and potassium nutrients, Improve crop disease resistance, drought resistance, cold resistance, and reduce the occurrence of deficiency syndrome.
Take vegetable crops such as cucumber and tomato as examples. Cucumber and tomato are crops that are continuously flowering, fruitful, and harvested. According to the Ministry of Agriculture, about 3 kg of nitrogen, 1 kg of phosphorus pentoxide, and oxidation are required for every 1000 kg of cucumber produced. Potassium 2.5 kg, calcium oxide 1.5 kg, magnesium oxide 0.5 kg.
Cucumber, tomato and other crops have a higher amount of vegetative growth nitrogen fertilizer in the early stage, and can not be deficient in phosphorus and boron during flowering. In the end, potassium and calcium should be increased, and magnesium fertilizer should be added in the middle and late stages. In other words, nutrient balance should be achieved throughout the growth period.
In the case of mastering the balance of nutrients, it is also necessary to pay attention to the combined use of water-soluble organic matter, including the use of carbon dioxide gas fertilizer. All in all, the integration of water-soluble fertilizer and water and fertilizer is the development direction of China's agriculture and a revolution in the fertilizer industry. We must continue to learn from foreign experience, and we must continue to innovate, optimize resources, update formulas, reform methods, adapt to crop growth patterns, and obtain good yields and benefits on the basis of ensuring food safety.
