Water Soluble Fertilizer (WSF) is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water, and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. The key point is that it can be applied to agriculture such as spraying and drip irrigation to realize the integration of water and fertilizer, and achieve the efficiency of the provincial water-saving province.
Water soluble fertilizer advantages:
One reason, nutrients
Water-soluble fertilizer not only has a large amount of elemental nitrogen, phosphorus, potassium, but also rich in trace elements such as molar water-soluble fertilizer containing iron, manganese, zinc, copper, calcium, magnesium, boron, molybdenum, etc., chelated trace elements are more easily Absorption and transformation, in addition to active organic matter such as amino acids and humic acid (regulating soil compaction). The general fertilizer is only a single element. Long-term use of the soil will cause consolidation and acid-base imbalance problems.
Second reason, the province of fertilizer
Conventional application of fertilizer to an area of more than 40 kilograms is a bag, and requires two people to operate very troublesome, and water-soluble fertilizer is only a fraction of chemical fertilizers, such as the German Moore soluble fertilizer 5 kilograms can be applied to a mu of land, One can quickly top-dress.
Reason three, low prices
A bag of ordinary chemical fertilizer is about 100 yuan, while the price of water-soluble fertilizer is similar to this, then from the comparison of fertilizer efficiency and dosage, it is natural that water-soluble fertilizer is practical and the investment cost is naturally reduced.
The fourth reason is that there is no pollution
The long-term use of chemical fertilizers will cause various degrees of damage to the soil and the environment. The water-soluble fertilizers themselves are all the nutrients needed by the plants. They are used in a large quantity without any pollution problems, and the newly mentioned humic acid component can also improve the acid-base imbalance of the soil. The problem can be described as two birds with one stone.
Reason 5. Development Trend
In recent years, China has introduced many preferential policies for agriculture, such as support for agricultural subsidies, subsidies for agricultural machinery, and the integration of water and fertilizer policies introduced in the No. 1 document of the Central Government. After large-area land circulation, large-scale mechanized planting and fertilizer management will be implemented. The specific analysis is as follows: :
(1) Water resources. China is one of the countries with a lack of freshwater resources in the world. Problems such as seasonality and uneven distribution of industries and regional water shortages are prominent. Water-soluble fertilizer as a new type of environmentally-friendly fertilizer can be sprayed, sprayed, and used in combination with drip irrigation to increase fertilizer utilization, save water for agriculture, reduce ecological pollution, improve crop quality, and reduce labor.
(2) Modern agriculture is essential, traditional agriculture pays attention to slash-and-burn, and modern agriculture pursues four major goals: green, high-efficiency (water-fertilizer integration), pollution-free, and production increase, and the emergence of water-soluble fertilizer just happens to promote rapid development. And the huge demand of the market.
(3) Soil circulation, large-scale planting will inevitably require lower cost operation, and fertilization is one of the major problems. Reducing the cost of fertilizer (amount, labor) is a necessary condition for increasing the profit of the acres, and the water-solubility mentioned before. The amount of fertilizers and the amount of labor required to meet these requirements are very good, and the demand for natural water-soluble fertilizers will also increase.
Water soluble fertilizer used 诀窍:
Although the use of water and fertilizer integration technology for the application of water-soluble fertilizers has brought a lot of convenience to agricultural production, the use of water-soluble fertilizers will also bring disasters. It is imperative to strictly apply fertilizing time and fertilizer usage.
Below, Xiao Bian came to show you some tips for using water and fertilizer.
When watering and fertilizing, the temperature of the water should be as close to the ground temperature and temperature as possible, and do not flood the area. Watering the greenhouse in winter, try to water in the morning; in the summer, try to choose to water in the afternoon or evening. If you don't use a dropper, try pouring water as little as possible. Flood irrigation can easily cause soil compaction, hindrance to root respiration, affect nutrient absorption, and easy rot and dead trees. Promoting "cultivation on ridges" is conducive to high crop yields.
Only scientific fertilization can produce ideal yield and quality. Scientific fertilization is not just about the distribution and quality, but also the amount of science. In general, terrestrial vegetables use 50% water-soluble fertilizer, and the amount of mu is about 5 kg, plus about 0.5 kg of water-soluble organic matter such as humic acid, amino acids, and chitin, in addition to the addition of nitrogen, phosphorus, and potassium nutrients. Improve crop disease resistance, drought resistance, cold resistance, and reduce the incidence of deficiency diseases.
Taking cucumber and tomato vegetable crops as an example, cucumber and tomato are crops that are continuously flowering, fruiting, and harvesting. According to the Ministry of Agriculture's test, about 3 kg of nitrogen, 1 kg of phosphorus pentoxide, and oxidizing 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 in the early period of vegetative growth of nitrogen fertilizer a large number of flowering can not lack phosphorus and boron, the results of the period to increase the amount of potassium and calcium, pay attention to supplement magnesium in the late. In other words, nutrient balance should be achieved throughout the growth period.
In the case of mastering the balance of nutrients, we must also pay attention to the use of water-soluble organic substances, including the use of carbon dioxide gas fertilizer.
In a word, the integration of water-soluble fertilizer and water and fertilizer is the development direction of China's agriculture, and it is the revolution of the fertilizer industry. We must continue to learn from foreign experiences, and we must continue to innovate, optimize resources, update formulas, and reform methods, adapt to the laws of crop growth, and obtain good yields and benefits on the basis of ensuring food safety.
