不同种类缓混肥对常农粳12号水稻生长的影响研究

随着农业高质量发展的不断推进,传统的施肥模式已无法满足农业生产转型,缓混肥应用技术不断普及,市场上涌现出了大量不同品种的缓混肥,筛选一款适合本地区农业生产的缓混肥尤为重要,对推动本地区农业现代化发展具有重要意义。本试验通过选取3个不同品种的缓混肥,研究分析了其对常农粳12号水稻生长的影响。研究结果表明：不同品种缓混肥对常农粳12号水稻生长及其产量存在一定的差异,其中汉枫(30-6-12)效果最佳。其能有效提高常农粳12号的最高分蘖数,比施用艾萨斯(33-5-12)提高了10.6%。其在抽穗前期及成熟期能有效提高剑叶SPAD值。其可提高常农粳12号水稻植株关键生育期各部位的全氮含量,为水稻生长提供充足养分支撑。施用汉枫(30-6-12)缓混肥同样能提高常农粳12号水稻的生物量,在成熟期分别比施用艾萨斯(33-5-12)和华昌(26-10-15)高1.2%和0.8%。在水稻产量方面,施用汉枫(30-6-12)缓释肥后理论产量分别比施用艾萨斯(33-5-12)和华昌(26-10-15)提高了0.07%和0.15%,实际产量分别提高了9.6%和6.1%。

Effect of Different Slow Mixed Fertilizers on the Growth of Changnongjing 12 Rice

With the continuous promotion of high-quality agricultural development, the traditional fertilization mode has been unable to meet the transformation of agricultural production, and the application technology of slow mixed fertilizer has been popularized. A large number of slow mixed fertilizers of different varieties have emerged in the market. It is particularly important to select a slow mixed fertilizer suitable for agricultural production in this region, which is of great significance to promote the development of agricultural modernization in this region. In this experiment, three kinds of slow mixed fertilizers were selected to study their effects on the growth of Changnongjing 12 rice. The results showed that different varieties of slow mixed fertilizers had certain differences in rice growth and yield of Changnongjing 12, among which Hanfeng (30-6-12) had the best effect. It can effectively increase the highest tiller number of Changnongjing 12, which is 10.6% higher than that of Aisas (33-5-12). It can effectively improve SPAD value of flag leaves in the early heading stage and maturity stage. It can increase the total nitrogen content in all parts of rice plant during the key growth period of Changnongjing 12, and provide sufficient nutrients for rice growth. The application of Hanfeng (30-6-12) slow mixed fertilizer can also improve the biomass of Changnongjing 12 rice, which is 1.2% and 0.8% higher than that of Aisas (33-5-12) and Huachang (26-10-15) respectively at the mature stage. In terms of rice yield, after applying Hanfeng (30-6-12) slow release fertilizer, the theoretical yield increased by 0.07% and 0.15% respectively compared with that of Aisas (33-5-12) and Huachang (26-10-15), and the actual yield increased by 9.6% and 6.1% respectively.
