Study on Fertilizer Application and Yield Model of‘Yongyou 12’and Its Fertilization Techniques in Super-high-yielding Cultivation Single Cropping Rice
摘要
Abstract
The relationship between fertilization level and yield of‘Yongyou 12’and the technique of fertilization for super high yield cultivation were studied in this research. Fertilization was conducted according to the soil fertile level under the unified cultivation technology. Follow up investigation was carried out of 12 demonstrations of different fertilizer combinations and the amount of fertilizer from 2012 to 2013. The rice yield was examined by the experts harvesting. Our data serve as a useful tool for elucidating the relationship between fertilization level and yield of‘Yongyou 12’and its fertilization techniques in super-high-yielding cultivation. The results showed that under moderate soil fertility levels, the yield (Y) of‘Yongyou 12’was accelerated with the increase of fertilizer application, according with the power function showed as Y=0.00003F2-0.2963F+11302 (Y=0.2301F+9258), Y=0.0504N2+24.566N+1953 (Y=51.243N-1543), Y=0.0361P2+26.596P+870 (Y=34.143P+8358), Y=0.0208K2+7.4996K+8499 (Y=17.793K+7306). Based on the function, the paper summarized a fertilizer combination for‘Yongyou 12’to obtain yield to 11000-12000 kg/hm2, in which, organic fertilizer was 8000-12000 kg/hm2, nitrogen (N) was 245-265 kg/hm2, phosphor (P2O5) was 75-105 kg/hm2 and potassium (K2O) was 210-265 kg/hm2, the structure of N, P, K ratio was 1.00:0.35:0.93. In another fertilizer combination for‘Yongyou 12’to obtain yield to 15000 kg/hm2, organic fertilizer was 15000-20000 kg/hm2, nitrogen (N) was 320 kg/hm2, phosphor (P2O5) was 190 kg/hm2 and potassium (K2O) was 410 kg/hm2, the structure of N, P, K ratio was 1.00:0.59:1.28, and this combination increased both production costs and risk remarkably. For living up to the expectations, a series of coordination measures were suggested including super cultivation, fertilizer application, water management and control of diseases and pets.关键词
