小麦精量播种是在地力、肥力条件较好的基础上,通过适期早播,高质量播种,减少基本苗,冬前培育壮苗等综合配套技术措施,以协调群体与个体、高产与倒伏的矛盾,使麦田群体动态结构比较合理,改善群体内光照条件,以争取分蘖成穗为主,达到穗足、穗大、粒多、粒重、高产。主要配套技术如下。一、选用优良品种小麦精播高产栽培应选用分蘖成穗率高、丰产潜力大、耐水耐肥、抗倒伏、株型紧凑、光合能力强、落黄好、抗病抗逆性好的优良品种。如百农矮抗58、郑麦366、西农979等品
Precision sowing wheat is based on the better soil fertility conditions, through early sowing the appropriate period, high-quality sowing, reducing the basic seedlings, seedlings and other comprehensive training measures before winter to coordinate groups and individuals, high yield and lodging The dynamic structure of wheat field is more reasonable and the light conditions in the population are improved so as to achieve tillering and earning, reaching ear foot, ear, grain, grain weight and high yield. The main supporting technologies are as follows. First, the selection of fine varieties of wheat sowing high-yielding cultivation should use tillering rate of high spikes, high yield potential, water and fertilizer, lodging, compact plant type, strong photosynthetic ability, good yellow, good resistance to disease resistance varieties . Such as hundred agricultural short anti-58, Zheng Mai 366, Weston 979 and other products
