寒地水稻氮素调控新型施肥技术示范

【研究目的】研究新型氮素调控技术对水稻生长发育和产量的影响；【方法】利用大区对比的方法；【结果】INM处理株高比FFP处理高，分蘖比FFP处理多，水稻鞘腐病和褐变粒均明显比FFP处理轻。INM处理穗大且整齐，剑叶大，倒伏明显比INM处理轻，水稻植株衰老过程慢，根系颜色新鲜，白根多，根系活力强，平方米有效穗、穗实粒数、穗瘪粒数、产量均比FFP处理高，穗长和千粒重接近。平方米有效穗多15．2个、穗实粒数多2．8个，公顷产量达到11．679t，增产16．8％。【结论】INM施肥方式明显优于FFP。

The Demonstration about New Applying Fertilizer Technology of Paddy Rice in The Cold Place

OBJECTIVE]It is studied that the effect by new applying nitrogen technology on growth and output ot paddy rice;METHOD]using district contrast method; RESULTS]The plant of INM treatment is higher and tillers are more than the FFP treatment, The vagina rotten disease and brown granule are obvious lighter. The tassel is big and tidy, the sword leaf is longer, Beating down is obvious lighter, the senility is slower, The root is stronger than the FFP treatment, The effective ear and the granule and output are higher. The effective ear of square meter and ear＇s reality granule of the INM treatment are more 15.2 and 2.8 respectively than the FFP treatment, output of the INM treatment reaches ll.679t/hm^2, the production increases by 16.8%.CONCLUSION]INM is obvious better than FFP.
