研究表明,(1)地膜玉米中单2号雄穗和雌穗分化历时分别为 34,26 d时,分化始期的可见叶和叶龄分别为 8.8,6.5和 11.0,7.7。与露地玉米相比,雄穗分化期缩短 16 d,雌穗分化期缩短12人在穗分化的前期和中期,地膜玉米的叶数均显著多于露地玉米。(2)地膜玉米雌雄穗分化期的对应关系与露地玉米基本一致。(3)地膜玉米要求栽培措施比露地玉米早而及时。前期和中期管理的叶龄值比露地王米多1,后期与露地玉米基本一致。(4)地膜玉米各分化期的叶面系数均显著大于露地玉米是其增产的主要原因之一。
The results showed that: (1) When the number of single tassel and ear of maize in the mulched corn lasted for 34 and 26 days respectively, the visible leaf and leaf age at the beginning of differentiation were 8.8, 6.5 and 11.0, and 7.7, respectively. Compared with the field maize, the tassel differentiation stage was shortened by 16 days and the ear differentiation stage was shortened by 12. In the early and middle stages of panicle differentiation, the number of maize leaves was significantly more than that of the field maize. (2) The corresponding relationship between maize and maize differentiation stage of maize was basically the same as that of maize. (3) Plastic film corn requires cultivation measures earlier and faster than the field corn. Prophase and mid-term management of the leaf age value of more than a meter open field rice, late and open field corn is basically the same. (4) The leaf surface coefficient of plastic film corn was significantly higher than that of open field corn at one time.
