根据近几年的生产实践以及对高产田的连续调查,总结了南疆复播玉米高产栽培技术。 一、精细播种。打好一播全苗的基础 1、播前选纯度高,均匀一致的大粒种子,提高出苗率。 2、早播,复播玉米早播就意味着延长籽粒灌浆期,提高产量。播种深浅一致,确保出苗整齐。 3、种肥隔离(施在种子一侧或二侧),种子距肥7-8厘米,以免种肥接触,引起烧种。土壤墒情要足,避免种子落干。 According to the production practice in recent years and the continuous investigation of high-yielding fields, the high-yielding cultivation techniques of corn replanting in southern Xinjiang were summarized. First, fine sowing. Lay a good foundation for planting seedlings 1, sowing before the election of high purity, uniform large seeds, improve the emergence rate. 2, early sowing, sowing corn early broadcast means to extend the grain filling period, increase production. Sowing the same depth, to ensure that the emergence of neat. 3, the kind of fertilizer isolation (applied to one or both sides of the seed), seed 7-8 cm away from fertilizer, so as to avoid fertilizer contact, causing burning seed. Soil moisture content should be enough to avoid the seeds fall dry.
