为验证马拉松~缓释肥料对水稻生产的节肥、省工、节本、增产、增效作用,特进行了马拉松~缓释肥料的应用效果试验示范。结果表明,在水稻分蘖期,处理(2)(缓释肥区)每667 m~2只施促蘖肥马拉松R缓释肥25kg、不施保蘖肥,在比处理(1)(常规肥区)每667 m~2减施N 3.05 kg、P_2O_5 0.1 kg、K_2O 0.5 kg的条件下,肥料用量减少14.9%,成穗率提高6.3%,每穗实粒数增加5.01%,理论产量和实收产量分别增产3.69%、2.04%,每667 m~2节本增效55.97元。
In order to verify the marathon ~ slow-release fertilizer on rice production of fertilizer, labor-saving, section, increase production, synergistic effect, special marathon ~ slow release fertilizer application effect demonstration. The results showed that in the tillering stage of rice (2) (slow-release fertilizer zone), only 66kg straw-maturity slow-release fertilizer 25kg was applied per 667m 2, no tillering fertilizer was applied, Under the conditions of N 3.05 kg, P 2 O 5 0.1 kg and K 2 O 0.5 kg per 667 m ~ 2, the amount of fertilizer decreased by 14.9%, the rate of ear formation increased by 6.3% and the number of grains per panicle increased by 5.01% Yields were increased 3.69%, 2.04%, every 667 m ~ 2 cost-effective 55.97 yuan.
