生产实践和科学研究证明,要使小麦低产变中产,在栽培技术上的关键是处理好小麦植株的生长发育与土、肥、水生产条件的矛盾。因此,首先必须大搞以土、肥、水为中心的农田基本建设,并随着土、肥、水生产条件的改善,逐步增加播种量,缩小行距,实行合理密植,依靠主茎穗,争取穗多增产。但穗数到了一定程度,例如在山东省,“蚰包麦”每亩达到50—60万穗,“泰山4号”等品种每亩达到40—50万穗,再增加穗数,
Production practice and scientific research have proved that in order to make wheat low-yield change in the middle of the production technology, the key is to deal with the contradiction between the growth and development of wheat plants and soil, fertilizer and water production conditions. Therefore, first of all, we must vigorously promote farmland construction centered on soil, fertilizer and water. With the improvement of production conditions of soil, fertilizer and water, we should gradually increase the seeding rate, narrow the line spacing, implement a rational close planting and depend on the main stem spike Spike more production. However, the number of spikes reached a certain level. For example, in Shandong Province, “Shuo Baomei” reached 50-60 million spikes per acre and that of “Taishan No.4” reached 40-50,000 spikes per acre,
