摘要
根据近年来的小区试验和潍坊市麦套紧凑型夏玉米单产 1 0 5 0 0～ 1 1 2 5 0kg/hm2 的生产实践 ,总结出了提高麦田套种紧凑型夏玉米创高产的 1 3项关键配套栽培技术 :即增加有机肥用量 ;足墒匀墒播种 ;确保一次播种保全苗 ;合理增株 ,充分发挥群体的增产优势 ;预防大小苗 ,提高苗期田间整齐度 ;苗期早管 ,促苗早发培育壮苗 ;重施孕穗肥 ,为高产奠定基础 ;防虫治虫 ,为玉米创造良好生育环境 ;及时中耕松土 ,提高土壤的通透性 ;及时去雄 ,改变养分分配方向补施攻粒肥 ,促穗大增粒重 ;及时灌溉 ,满足生理用水 ;适当晚收 ,增加光合积累等配套栽培技术 。
According to the plot experiments and high yield experiences of summer maize with 10 500～ 11 250 kg/hm 2 in Weifang, thirteen items of crucial culture techniques were summed up to reach high yield by interplanting erectophile type summer maize in the wheat field. Namely: Increase the content of organic manure and fertilize adequate base fertilizer with formula; Choose the erectophile type varieties to play its full role in raising yield; Sow the summer maize under the condition of enough and equal soil moisture to make the seedlings sufficient by only sowing once; Increase reasonably the plant density of maize to make full use of the canopyshigh yield potential; Prevent the Seedlings from having large or small ones to increase its symmetrical degree; Promote the seeds to emerge early and train strong seedlings; Fertilize enough booting manure so as to get high yield; Prevent and kill pests to create a good environment for maizes growth and development; Cultivate and loosen the soil in time to increase its gas permeability; Emasculate in time to change the distribution of nutritious matter; Supplement filling grain manure to from big ears and raise its kemel weight; Irrigate in time to meet the needs of phisiological water for maize to increase photosynthetic accumulation, etc. The application of all the techniques can increase significantly the summer maize yield.
