不同水稻品种不同种植方式对水稻生长发育及产量的影响
摘 要
水稻是江苏省的第一种粮食作物,长期种植面积和总产量分别占该省粮食总产量的40%和60%,但江苏省的水稻种植格局则多种多样。种植模式的多样化妨碍了综合生产管理,妨碍了水稻规模标准化的发展,严重影响了大规模生产的平衡增长、水稻种植模式的科学选择以及稻米生产的平衡增长。根据对江苏省大型和中型农庄采用水稻种植技术的情况所作的统计分析,对不同种植方式的水稻生产及其特点以及不同种植方式的水稻生产和生产投入进行了一次详细的比较研究。此外,江苏省在选择稻米生产方式时,面临的挑战和进一步提高稻田生产的主要方向是一个重要的基准。这项研究对不同作物品种对稻米生产的影响及其经济效益进行了测试,这对于引导大规模的农业稻米生产十分重要。直播稻技术更多的是靠播种量来保证基本苗,进而保证成穗数,从而达到高产,而机插秧主要靠有效分蘖来保证成穗数进而达到高产,从整体效益上机插秧优于直播稻;品种比较试验表明,机插秧下南粳9108的平均产量最高,亩产量能高达708kg;肥料试验表明,机插秧下南粳9108在施氮量为240kg/hm2时亩产量达到最高,但其与施氮量为360kg/hm2的产量并无显著差异。

EFFECTS OF DIFFERENT RICE VARIETIES AND PLANTING METHODS ON RICE GROWTH AND YIELD
ABSTRACT
Rice is the first food crop in Jiangsu Province. The longterm planting area and total output account for 40% and 60% of the total grain output of the province respectively, but the rice planting pattern in Jiangsu Province is diverse. The diversification of planting mode hinders the comprehensive production management, the development of rice scale standardization and the balanced growth of largescale production. Therefore, a detailed comparative study on rice production and investment of different planting methods in Jiangsu Province was carried out. This study shows that the direct seeding rice technology is more to ensure the basic seedlings by sowing quantity, and then to ensure the number of panicles, so as to achieve high yield, while the machine transplanting rice mainly depends on effective tillering to ensure the number of panicles to achieve high yield, which is superior to the direct seeding rice from the overall benefit; the variety comparison test shows that the average yield of Nanjing 9108 under the machine transplanting is the highest, and the yield per mu can be as high as 708kg; the fertilizer test table The results showed that the yield of Nanjing 9108 was the highest when the nitrogen rate was 240kg / hm2, but there was no significant difference between the yield of Nanjing 9108 and that of 360kg / hm2.
