Deep application of fertilizers, on the one hand, can reduce the loss of nutrients caused by rain, evaporation, etc., and directly achieve the purpose of saving fertilizer; on the other hand, deep application can increase the absorption rate of nutrients by roots, and cultivate large and thick roots, which can Effective anti-falling effect, reducing losses. For example, after deep application of fertilizer, the amount of root coefficient in rice can be increased by 50%, which enhances the lodging resistance.
Lodging is one of the important causes of rice yield reduction, including root lodging and stem lodging. The root lodging is mainly caused by the shallow roots of rice and the poor development of the lower roots, and the stem lodging is mainly caused by the thin base of the stem and the undeveloped mechanical structure. In recent years, with the promotion of high-yield and high-yield rice varieties, lodging has been a major threat to the yield potential of these varieties.
The root system is an important organ for crops to absorb nutrients. The vigorous roots are derived from a good soil nutrient environment and are also feedback of the vigorous growth of the aboveground parts. The cultivation of large roots in production can significantly increase above-ground biomass, enhance lodging resistance, and increase crop yield. Deep application of fertilizer can significantly increase the dry weight and volume of rice roots, help to increase root retention and enhance the ability of rice to resist lodging.
However, there are some problems with deep application of fertilizer in rice. For example, when rice is transplanted, it is impossible to apply deep fertilizer. This requires all the nutrients needed for growth and development to be applied at a time before rice transplanting, and rice controlled release fertilizer can solve this problem.
Fertilizer deep application method
The most direct and simple way to save fertilizer is to carry out deep application of fertilizer. Taking urea as an example, the utilization rate after deep application can reach 47%-50%, and the utilization rate after the application is only 25%. Obviously, deep application can significantly improve fertilizer utilization and save fertilizer costs.
