Description
Technical Field
The invention relates to the technical field of fertilizer manufacturing, in particular to a liquid fertilizer for root cultivation and a preparation method thereof.
Background
Compound fertilizers are one of the major development directions of the fertilizer industry in the world. The chemical fertilizer applied in developed countries in the world is mainly single fertilizer and mainly high-concentration compound fertilizer. 80% of nitrogen fertilizer and 90% of phosphorus fertilizer and potassium fertilizer are all processed into special high-efficiency compound fertilizer and then applied. Simple chemical fertilizers are generally not directly applied. The development direction of the fertilizer in the world is multifunctional, multielement, liquidized, high-efficiency compounded and secondary processing formula. The american compound fertilizer secondary processing plant has evolved from over three thousand in 1970 to nearly ten thousand in 1980, where liquid compound fertilizer production has accounted for about 1/3. By 1986, the effective utilization rate of the fertilizer in the United states has reached 60%, and the average effective component of the fertilizer is about 40%. In 1981, the production capacity of the liquid compound fertilizer in the United states reaches 300 ten thousand tons.
In 12 months in 1986, experts and scholars from all over the world in the association of liquid fertilizers held in new orleans city in the united states had a belief that "china should use liquid fertilizers to more effectively increase the yield per unit area of crops". The liquid fertilizer is the most novel comprehensive fertilizer in the world, and is flexibly applied along with each growth period of crops through a scientific formula according to the comprehensive requirements of the crops on different growth periods. According to the repeated practice in foreign countries, the liquid fertilizer is an effective means for ensuring high and stable yield, and is expected to be unique to any solid fertilizer.
The chemical fertilizer industry in China has been greatly developed since the establishment of the nation, and the total yield accounts for the third place in the world. But still has a great gap from the requirement of modern agricultural production. The proportion of nitrogen, phosphorus and potassium is seriously disordered, for example, in 1984, the total yield of the fertilizer in China is 1482 ten thousand tons according to effective components, the proportion of the three fertilizers is 1: 0.21: 0.003, the proportion of the three fertilizers is 1: 0.6: 0.5 in developed countries in the world, the proportion of the three fertilizers in developed countries is 1: 0.4: 0.25, and the proportion of the three fertilizers in developed countries in China is seriously deficient in phosphorus and potassium fertilizers. Secondly, because ammonium bicarbonate accounts for 60% of nitrogenous fertilizers in China and phosphate fertilizers are mainly ordinary calcium, the average effective components of the fertilizers in China are less than 20% and are only half of those in the United states. And thirdly, in many areas, the nitrogen fertilizer is lack of phosphorus and potassium and is applied to a part to increase the morbidity and pollution of crops and cause the waste of the nitrogen fertilizer. Fourthly, the yield of the compound fertilizer only accounts for one thousandth of the total yield of the chemical fertilizers in China, and the imported compound fertilizer is about 5 percent. Fifthly, a regular secondary processing factory is not provided, and particle compound fertilizer factories reconstructed by small fertilizer factories are fixed in proportion; the effective components are low, generally not more than 25%, and the process is mostly unreasonable, so the product quality is poor. A secondary processing factory for the compound formula fertilizer just starts in China. At present, the simple substance fertilizer is applied without being secondarily processed into a special compound fertilizer in China, so that the effective utilization rate of the fertilizer is 25-30% and is only half of that of the United states, and the yield of grains in unit area is only 54% of that of the United states although the fertilizing amount in unit area in China is similar to that of the United states. Therefore, from the long-term development, the correct technical and economic route of compound fertilizer production can be developed only in China by producing special efficient compound fertilizers, especially special efficient liquid compound fertilizers, and the formulas of various nutrient elements are carried out according to different soil conditions and the fertilizer demand of crops, so that the proportions of different nitrogen, phosphorus, potassium and trace fertilizers are determined, and the special efficient granular and liquid compound fertilizers are prepared by secondary processing. The invention aims to provide a liquid fertilizer with the functions of protecting and nourishing roots of crops.
