The key to formulating fertilization by soil testing is to determine the type and amount of fertilizer. There are many ways to determine the type and amount of fertilizers, such as soil and plant test recommended fertilization method, fertilizer effect function method, soil nutrient abundance index method, nutrient balance method and so on. In China, there are many reports on the research of soil testing and fertilization for rice, but there are few reports on soil testing and fertilization for no-tillage and throwing rice. Based on the climate and soil characteristics of Guangxi, the effects of soil fertigation and formula fertilization on no-tillage and cast transplanted rice were discussed. The dependence of no-tillage and castrated rice yield on soil nutrient and the agreement between soil test fertilization and target yield were analyzed. This provides a reference for production.
The experiment was carried out in 2006 at Gaopo 2 Team, Gaoqiao Village, Qingfeng Town, Gangbei District, Guigang City, Guangxi Province. The rice crop was pre-planted, and it was not plowed in winter. The soil was in a shallow iron field with uniform fertility, flat terrain, and convenient drainage and irrigation. Before the test, the soil of the cultivated layer was used for the soil testing formulation by the soil testing and fertilization information inquiry machine. According to the results of the diagnosis, the intelligent expert decision-making system put forward the target yield and fertilization recommendations. The predicted target yield is 6750 kg/hm2. To achieve this goal, the fertilization proposal gives seven fertilization plans, from which option 3 is selected for testing.
From the comparison of soil fertility and conventional fertilization in soil testing formulation fertilization information inquiry machines, it was found that the yields were 106123% and 10128%, respectively; and the differences between treatments were significant. The effective panicle, plant height, panicle length, number of panicles, number of grains, and seed setting rate of soil testing and formula fertilization were significantly higher than those of no fertilization. Compared with conventional fertilization, except for the significant difference in plant height, the other traits were not significantly different. . The tendency of tillering of formula fertilization by soil testing was consistent with that of conventional fertilization, and the number of tillers per plant was much higher than that of no fertilization. The coincidence of yield and target yield of the formula fertilization for no-tillage and cast transplanted rice was 106115%, which was basically consistent with the previous research results. This shows that soil testing and fertilization on no-tillage and cast transplanted rice can adjust and solve the contradiction between crop demand fertilizer and soil fertilizer supply, realize various balanced nutrient supply, increase fertilizer utilization and reduce fertilizer use, increase production, The purpose of saving and increasing income.
Application of Soil Testing and Formula Fertilizing Information Query Machine in No-tillage and Seedling-casting Rice Soil Testing Formulation
In recent years, in order to improve the rising cost of agricultural production in rural areas, aggravate environmental pollution, improve the quality and safety of agricultural products, and vigorously promote the new techniques of soil testing and fertilizer application. The basis of this technology is based on soil testing and fertilizer field trials, combined with the requirements of crops, soil fertility and the effects of fertilizers, and put forward reasonable application rates, application periods, and technical measures for application methods. The core of this technology is to solve the contradiction between crop demand fertilizer and soil fertilizer supply, realize the balance between supply and demand, increase the utilization of fertilizer and reduce the amount, so as to achieve the increase of crop yield, improve the quality of agricultural products and reduce production costs, protect the ecological environment, and promote The purpose of sustainable development. While vigorously promoting the technology, the soil testing and fertilizing information inquiry machine was also born and gradually improved.
