小麦产量由亩穗数、穗粒数和粒重三因素所构成。它们之间的关系是否合理协调,乃是小麦产量丰欠的关键。为此,我们进行了多年的观察、分析,探索调节最佳成产因素结构。一、小麦叶、蘖发生规则小麦叶蘖的发生按照一定顺序位次和数目出现的规则。在实际应用中,由于品种特性、播期、播量、播种深浅以及水、肥、温、光等条件的影响,分蘖数并非完全符合其规则:但在一般正常情况下,在主茎7叶令以前,大都基本符合:而主茎7叶令以
Wheat yield by the number of acres per spike, grain number and weight of three factors. Whether the relationship between them is reasonably coordinated is the key to the abundance of wheat. To this end, we conducted years of observation, analysis, exploration and adjustment of the optimal production structure. A wheat leaf, tiller rules Wheat tiller occurs according to a certain order of order and number of rules. In practical application, due to the characteristics of varieties, sowing date, sowing quantity, sowing depth, and the influence of water, fertilizer, temperature and light, the number of tillers is not in full compliance with its rules. However, under normal circumstances, In the past, most basically in line with: while the main stem 7 leaf order
