Description

Fertilizer injection unit for rice planting

Technical Field

The utility model relates to a rice fertilization equipment design field especially relates to a fertilizer injection unit is used in rice planting.

Background

The rice is annual gramineous plant, is one of the most important grain crops in the world, the rice yield is influenced by a plurality of factors such as rice field water management, climate, fertilization and the like, and the fertilization is one of effective measures for ensuring the high and stable yield of the rice, can improve the soil environment and the soil fertility, and further enables the yield to be stably increased. The fertilizer is an important agricultural production data, and among various yield increasing factors, the fertilizer has the effect of increasing the yield by 40-65%. At present, china is one of the countries with the most fertilizer consumption in the world, and nitrogen is an important limiting major element for rice production and also an important factor for increasing the yield of rice. In recent years, the rice planting area of China accounts for 20% of the world, the nitrogen fertilizer consumption accounts for 37% of the world, and the average single-season nitrogen fertilizer consumption of the rice field of China is 180kg/hm ² The usage amount of the product is 75 percent higher than that of the unit area of the world. After the nitrogenous fertilizer is applied to irrigated rice fields, the utilization rate of the nitrogenous fertilizer is relatively low because the nitrogenous fertilizer is lost due to volatilization, denitrification, surface loss, leakage and the like of ammonia in a soil-water system. After nitrogen fertilizer is applied, the concentration of ammonium nitrogen in the water on the surface of the rice field is increased, and the pH value is increased, so that the volatilization loss of ammonia is caused. The deep application of the nitrogen fertilizer is the most effective way for improving the utilization rate of the nitrogen fertilizer in flooded rice fields. Compared with the traditional surface application method, the deep application of the nitrogen fertilizer can not only reduce the loss of nitrogen, but also increase the yield. Therefore, the deep application of the nitrogen fertilizer can often obtain higher utilization rate. The ultra-large granular urea adopts a deep application method, and the dosage of the suitable nitrogen fertilizer is 76 to 93 percent of the optimal dosage required by the traditional fertilization method. Although a rice fertilizing device is developed at present, the problem that a fertilizing pipe is blocked and ditched to cause mud to be accumulated near seedlings easily occurs when the current fertilizing device deeply applies nitrogen fertilizer, and the fertilizing device cannot be widely used due to high cost and inconvenient use, so that most of the prior fertilizing devices cannot be widely usedThe rural area still adopts the manual work to lose and spill and fertilize to the rice, and fertilization not only wastes time and energy like this, and the fertilizer utilization ratio is also relatively lower moreover.
