Research on High-yield and Efficient Planting Technology of Summer Corn Cangnong 199
摘要
Abstract
In order to explore the high-yield and efficient planting technology of summer maize Cangnong 199,field experi-ments were conducted from 2021 to 2023,with different sowing dates(June 7,June 14,June 21),planting densities(60 000,67 500,75 000 plants/hm2)and plant models(60 cm equidistant rows,55 cm equidistant rows,70 cm/40 cm wide and narrow rows).The agronomic traits,yield and output value of summer maize Cangnong 199 in Cangzhou area un-der different treatments were comparatively analyzed.The results showed that compared with June 7 sowing date treatment,the yield of corn in June 14 and June 21 sowing date treatments increased by 16.72%and 16.37%;the yield of corn of 65 000 and 75 000 plants/hm2 planting density treatment increased by 5.36%and 4.89%respectively compared the planting density of 60 000 plants/hm2;the yield of corn of the wide and narrow rows 70 cm/40 cm model treatment increased by 5.70%and 5.84%compared with the equidistant rows 60 cm and equidistant rows 55 cm treatment.From the comprehensive analysis,the suitable sowing time of Cangong 199 is June 14-21,the suitable planting density is 67 500 to 75 000 plants/hm2,and the planting model is wide and narrow rows 70 cm/40 cm.关键词
