种植模式对不同夏玉米品种农艺性状、籽粒灌浆特性及产量的影响
Effects of Planting Patterns on Agronomic Traits,Grain Filling Characteristics and Yield of Different Summer Maize Varieties
摘要
Abstract
The main summer maize varieties Jingke 938(JK938)and Denghai 605(DH605)in Huang-Huai-Hai summer maize production area were selected as experimental materials,three treatments were set up,namely,single cropping with equal row spacing(60 cm,ER),single cropping with wide and narrow rows(80 cm+40 cm,WNR)and intercropping with 2:2 wide and narrow rows(WNRI),and the effects of planting patterns on agronomic traits,grain filling characteristics and yield of different summer maize varieties were studied,so as to screen the high-yield and high-efficiency planting patterns suitable for two varieties,and provide theoretical basis and practical reference for the optimization of maize cultivation techniques.The results showed that the plant height and panicle position height of JK938 and DH605 all exhibited WNR>WNRI>ER.The dry grain weight and harvest index of JK938 and DH605 generally exhibited WNRI>WNR>ER,and the harvest index of WNRI treatment significantly increased by 20.75％and 19.61％respectively,compared with ER treatment.For JK938 and DH605,the time when the maximum filling rate appeared,the filling amount when the maximum filling rate appeared,the maximum filling rate and the average filling rate were the largest under ER treatment,and the active filling period was generally the longest under WNRI treatment,which was 10.12 d and 20.28 d longer than ER treatment respectively.At 50 days after anthesis,the 100-grain weight of JK938 and DH605 were the highest under WNRI treatment.The orders of yields of JK938 and DH605 were WNRI>WNR>ER,and WNRI treatment significantly increased by 4.38％and 4.05％respectively,compared with ER treatment.DH605 had no bald tip under WNRI treatment.To sum up,in Huang-Huai-Hai summer maize production area,for JK938 and DH605,intercropping with 2:2 wide and narrow rows can coordinate the population structure,improve the distribution efficiency of photosynthetic products to grains,prolong the active filling period,and then promote the increase of maize yield.关键词
