Last year was the year of Guangdong Province's agricultural science and technology activities. The provinces and cities have promoted the first of 10 agricultural science and technology—one-step rice fertilization with controlled-release fertilizer. Yangjiang City in all counties and districts throughout the demonstration and demonstration process shows that the application of rice controlled-release fertilizer one-time fertilization technology's biggest advantage is to ensure steady growth of rice, increase production, while saving a lot of labor, a rice only need Once fat, it was deeply welcomed by the demonstrative people. The masses called the rice controlled-release fertilizer a “lazy manureâ€. Although it is lazy manure, the application of controlled-release fertilizers in Yangjiang City last year requires that the people's application techniques need to be improved. At present, the province's spring plowing and transplanting will enter the peak period. According to the experience of Yangjiang City agronomist, it is believed that the full use of the benefits of controlled-release fertilizer in one-time application of rice must master the following technologies: First, to determine the application of controlled-release fertilizer. Dosage, generally 40-45 kilograms per acre in paddy fields in our province, because controlled-release fertilizers slowly release nutrients, high absorption and utilization, excessive application will not only increase costs, cause waste, but also cause some pollution to the environment like ordinary chemical fertilizers. The second is to determine the application time, generally spread evenly before the last paddy field, after the application must be plowing field once, and then carry out throwing hoe, otherwise prone to growth imbalance; The third is generally no longer fertilizer in the rice growing period, because Controlled release fertilizers have a scientifically-designed ratio of nutrients and can meet the nutritional needs of rice for a lifetime. It is noteworthy that the application of controlled-release fertilizer in rice, leaf color is slightly lighter, is a green-green, different from the normal green fertilizer, green, leaf color blue green carbon nitrogen ratio in the plant is reasonable, help to improve resistance to disease and resistance Force is a kind of leaf color that is beneficial to stability and stability, and should not be blindly applied to nitrogen fertilizer because of the pale leaf color. Especially in the middle and late growth stages, if excessive nitrogen fertilizer is applied, the green color of the leaves will cause a “good and bad valley†phenomenon. The last point is to pay attention to the number of seedlings to be thrown (planted) in the seedlings, because the controlled-release fertilizers are slow-acting fertilizers. The supply of nutrients needed for early delivery is slightly insufficient, and the number of tillers is too small. Generally, early quality hybrid rice should be thrown 20000 basic seedlings, high-quality conventional rice to throw 30000 basic seedlings.
