中文摘要:
      为探明直播稻在不同的播量和施氮量条件下产量和品质的表现,研明直播稻高产优质适宜的播量和施氮水平,以新稻567、新稻568和新科稻31为试验材料,分别设置5个播种量和3个施氮水平,研究不同播量和施氮水平对直播稻产量和品质的影响。结果表明,在不同播量处理下,对于新稻567,在97.5 kg/hm2播量水平下产量最高为9.78 t/hm2,稻米的垩白粒率、垩白度较低,加工品质各播量间差异不显著;对于新稻568,在75 kg/hm2播量水平下产量最高,为9.58 t/hm2,且与各处理间差异达显著或极显著水平,稻米的加工品质和外观品质处理间差异不显著。稻米的食味品质在两品种不同播量间差异不显著,但总体表现为新稻567的食味值高于新稻568。在不同氮肥处理下,直播稻品种的产量基本表现为随着施氮量的增加呈先增加后降低的趋势,在255 kg/ hm2处理下产量达最大;稻米的加工品质各施氮处理间差异较小,外观品质差异较大,垩白粒率和垩白度基本表现为不施氮处理较小,施氮处理较大。这说明,在适宜播量下对于不同的直播稻品种可以实现高产和优质的协同提高;在适宜的氮肥处理下可以获得水稻的高产水平,但增施氮肥水稻的外观品质变劣,因此,协同直播稻的高产优质仅靠氮肥调控仍存在一定的局限性。
英文摘要:
      To find out suitable sowing amount and nitrogen application level for high yield and good quality direct sowing rice, and identify the yield and quality under different sowing amounts and nitrogen application rates,‘Xindao 567’,‘Xindao 568’and‘Xinkedao 31’were used as experimental materials, five sowing amounts and three nitrogen application levels were set up respectively to study the effects on yield and quality of direct sowing rice. The results showed that under different sowing amounts, the yield of‘Xindao 567’ reached 9.78 t/hm2 under the sowing amount of 97.5 kg/hm2. The chalky grain rate and chalkiness decreased. The processing quality of rice was not significantly different among different sowing amounts. The yield of ‘Xindao 568 reached the highest of 9.58 t/hm2 under the sowing rate of 75 kg/hm2, which was significantly different or extremely and significantly different among different sowing amounts. Rice taste quality had no significant difference among treatments of these two varieties, but the overall performance of‘Xindao 567’was higher than that of‘Xindao 568’. In different nitrogen treatments, the yield of direct sowing rice increased first and then decreased with the increase of nitrogen level, and the maximum yield was under the treatment of 255 kg/hm2. The processing quality was little different among different nitrogen treatments, and the appearance quality was largely different. The chalkiness rate and chalkiness degree were low under no nitrogen treatment, and higher under nitrogen treatments. The results showed that the suitable sowing amount of different varieties could achieve synergy of high quality and yield, and the high yield could be obtained by suitable nitrogen level. But the appearance quality decreased with the increase of nitrogen fertilizer. Therefore, only nitrogen fertilizer regulation has certain limitation on the cooperative development of yield and quality of direct sowing rice.
