The Regulatory Effects of Sodium Nitrophenolate·Naphthaleneacetic Acid Composite Agent at Different Concentrations on Direct-seeded Glutinous Rice'Xinyunuo 232'
摘要
Abstract
In order to investigate the application effect and appropriate concentration of 2.85%sodium nitrophenolate·naphthale-neacetic acid soluble concentrate on direct-seeded glutinous rice,a field plot experiment was conducted using'Xinyunuo 232'as ma-terial.Four dilution treatments of the agent were set up:2 000×(T1),3 000×(T2),4 000×(T3),and 5 000×(T4),with 1.4%sodium ni-trophenolate aqueous solution(2 500×)and 1%naphthaleneacetic acid aqueous solution(500×)as single-agent controls,and a blank control(clear water).Growth,development,and yield indicators were systematically measured.The results showed that 2.85%SNN soluble concentrate could significantly promote the growth and development of direct-seeded glutinous rice and optimize yield compo-nents.Among them,the 2 000×dilution treatment(T1)performed the best,with a basic seedling number of 136.8×104 plants·hm-2,maximum tiller number of 497.25×104 plants·hm-2,effective panicle number of 392.4×104 panicles·hm-2,1 000-grain weight of 22.03 g,seed setting rate of 95.2%,and a yield of 9.02×103 kg·hm-2,representing a 22.57%increase compared to the blank control(7.36×103 kg·hm-2).The yields for the T3 and T2 treatments were 8.75×103 kg·hm-2 and 8.72×103 kg·hm-2,with increases of 18.95%and 18.49%,respectively.The agent primarily achieved yield increases by promoting tiller occurrence,improving productive tiller percent-age,increasing effective panicle number and 1 000-grain weight.It was safe to rice within the tested concentration range,with no ob-served phytotoxicity.关键词
