怎样种好小麦?从小麦产量结构上说,穗多、粒多、粒重就能高产。目前小麦生产存在的问题主要是穗数不足,粒重不稳。我们分析了554份资料,初步看出:小麦亩产450斤以上,要有基本苗20万,有效穗31万,每穗实粒数29粒,千粒重34.5克。要具备这样的群体结构,必须以农业“八字宪法”为指针,首先抓好土、肥、水、种四大物质基础;然后围绕着抓苗增穗、提高粒重的主攻目标,采取相应的技术措施。现就小麦播种至成苗这个阶段,根据多年的试验和调查结 How to grow good wheat? From the wheat yield structure, spikes and more, more grain, grain weight can be high yield. At present, the main problems in wheat production are insufficient spikelets and unstable grain weight. We analyzed 554 data, initially found: more than 450 pounds of wheat per mu to have 200,000 basic seedlings, 310,000 effective spikelets, grains per spike 29 grains, grain weight 34.5 grams. In order to have such a group structure, we must take the “Eight-Character Constitution” of agriculture as the guideline and first grasp the four material foundations of soil, fertilizer, water and seed. Then, focusing on the main goal of grasping seedlings and increasing grain weight, Technical measures Wheat is now sown to this stage of development, according to many years of testing and survey results
