:总结了拱圆形塑料大棚温室进行玉米加代种植的技术措施 ,对应用大拱棚温室玉米加代种植的效果进行了评价。采用三层膜加草苫的保温措施使大拱棚具有良好的保温性能 ,温室玉米生长发育的环境温度平均比外界气温高 9℃左右。加代玉米一般 1月上旬播种 ,5月 1 0日左右散粉 ,6月上中旬收获 ,生育期约 1 5 0 d,说明大拱棚温室能够满足玉米种子纯度种植鉴定及玉米加代育种、繁种的要求。在玉米生育前期进一步采取有效措施提高小拱棚内的温度 ,能相应缩短加代玉米的生育期
: Summarized the arch circular plastic greenhouse greenhouse corn planting and technical measures, the application of large arch greenhouse greenhouse corn planting effect were evaluated. Adopting the three-layer film plus grass 苫 insulation measures, the big arch shed has good heat preservation performance. The average ambient temperature of greenhouse corn growth and development is about 9 ℃ higher than the outside temperature. Additional generation of corn generally sown in early January, about May 10 loose powder, harvested in mid-June, the growth period of about 150d, indicating that the large arch greenhouse can meet the purity of maize seed planting identification and maize plus the breeding and breeding requirements . In the early stage of maize to take further effective measures to improve the temperature inside the small shed, which can shorten the corresponding generation of corn growth period
