小麦浇水是一项增产效果明显的技术措施,在小麦生产中人们往往只重视越冬水和拔节水,而对早春水有所忽视,但近年来根据我们试验发现,小麦早春适时浇水增产效果显著。 早春浇水可以增加春季分蘖,巩固冬前分蘖,增加亩穗数,从而增加产量。经多年试验,对中低产田如能配以施肥,增产效果更显著。早春浇水可以保持适宜的土壤水份,对麦苗返青生长和幼穗分化都有良好的作用,不仅弥补了墒情的不足,也可使田间原有肥效与新施肥料相互补
Wheat watering is a technical measure with obvious yield increasing effect. People pay more attention to winter wintering and jointing water in wheat production, but neglect early spring water. However, according to our experiments in recent years, Significant. Early spring watering can increase spring tillers, consolidate winter tillers, increase the number of acres per acre, thereby increasing production. After many years of experiment, if medium and low yield fields can be allocated with fertilization, the yield increase effect is more remarkable. Early spring watering can maintain the appropriate soil moisture, green shoots growth and spikelet differentiation have a good role, not only to make up for the lack of moisture, but also make the original fertilizer and field fertilizers complement each other
