Influence of Basic Tillering and Panicle Nitrogen Proportion to the Quality and Output of Population of the Dry Derect Seeded Rice

[Objective]The study aimed to provide basis for comprehensive technique on large area production. [Method]With paddy Wandao 68 as test material,the influence of proportions of basic tiller fertilizer and panicle fertilizer on quality and output of the population of dry direct seeding rice was studied. [Result] The proportions of basic tillering and panicle Nitrogen with 6∶4 and 5∶5 have given the highest yield; No fertilizer of tillering was not good to enhance tillering rate and had very significant influence on the leaf age,but too much basic tiller fertilizer made ineffective tillers increased and effective leaf area ratio decreased; Proper tillering could raise the total amount of spikelet of unit area and the effective and high effective leaf chopper of population and grain-leaf ratio. [Conclusion]The best proportions of basic tiller fertilizer and panicle fertilizer were 6∶4 and 5∶5.
