Description
Technical Field
The invention relates to the technical field of crop fertilizer formulas, in particular to a spring corn synchronous nutrition formula fertilizer.
Background
Corn is an important grain crop in China, and has become the first agricultural product integrating grains, feed and processing raw materials in China according to the planting area and total yield of the grain crop. With the increasing population of China, the quality and the level of life of people are improved day by day, so that the demand of corn is increased continuously. The southwest area is one of three production bases of corn in China, the corn is one of main food crops in the area, and the sowing area and the yield of the corn account for about 15 percent of the total sowing area and the total yield of the corn in China. Meanwhile, the region is also the largest feed production region in China and the largest corn-blending region. At present, more than 70% of corns in southwest areas are distributed in mountainous areas and hills for planting, the plots are scattered, full mechanization cannot be realized, and the manual topdressing cost is high. In the area, the water and soil loss is serious, the high temperature, high humidity and high leaching are carried out under the climatic conditions, the soil fertility is lower and the spatial variation is large compared with the northern area, and the problems of overhigh fertilizing amount, low fertilizer utilization rate and the like of the corn generally exist.
According to the previous researches, nitrogen, phosphorus and potassium are essential nutrient resources for the growth and development of crops, and a large number of field experiments show that the application of nitrogen, phosphorus and potassium fertilizers can obviously improve the yield of corns. The nitrogen is the most important limiting factor influencing the corn yield, but the corn has low nutrient utilization efficiency, and researches such as Zhangfu and the like show that the agricultural efficiency of the nitrogen, phosphorus and potassium fertilizers of the corn in China is averagely 9.8, 7.5 and 5.7 kg.kg < -1 >, the utilization rates are 26.1%, 11.0% and 31.9%, wherein the utilization rate of the nitrogen fertilizer is lower than 60% of the total samples, and the main reason is that the excessive fertilization and the soil nutrient utilization are neglected.
Studies have shown that the postanthesis process accumulates approximately 50% of the dry matter during the development of maize, which plays an important role in kernel formation. At the same time, with increasing levels of yield (7.0Mg ha-1 to 13.0Mg ha-1), the proportion of dried matter after flowering increases from 47% to 60% and nitrogen uptake increases from 12% to 32%. However, in southwest areas, the fertilization before flowering is more, and the utilization rate of the fertilizer is low; insufficient topdressing after flowering and higher cost.
