| In order to solve the provice high-yielding rice soil testing and formula in kaishantun town of longjing, using soil testing and formula fertilization experiment plan "3414" in 2014 and 2014 in a kaishantun town, light zhao village 7 group Cui Guangzhe rice farmers in the rice soil testing and formula fertilization "3414" research is obtained by establishing the fertilizer effect model of N, P, K elements affect and rice, to test the mountain town, the rationality of applying fertilizer of rice, and adjusted and perfected.Through the experiment of "3414" design and methods, related data of 14 treatments on the growth and development of rice in different periods and analysis of rice for the test of soil, according to in this two-year period, growth and development of rice phenology and reproduction traits investigation. Analysis rice water two years growth differences and form factors of the data according to the yield and yield of rice, the data were analyzed according to the means of production costs.By testing the following conclusions:1. The test of rice planting in Kaishantun village, fertilizer absorption affected by weather conditions, affected by the amount of fertilizer production.2. In Kaishantun soil environment, N fertilizer for rice production development has an important influence, particularly important in the tillering and jointing booting stage, plenty of N fertilizer applied, can effectively improve the effective panicles and grain number, you can also add income large economic benefits, but more than a certain amount of fertilizer, but affect the yield and economic benefit. P and K fertilizer fertilizer fertilizer is not large, indicating that P and K fertilizer fat content is not very lack of soil.3. As can be seen from the analysis data of two years,14 years and 15 years of relatively stable yield and economic benefit is N2P2Kiã€N2P1K1, but also for further field trials, ensure the improvement of the soil environment, improve the economic benefit. |
