小撬是一种专门制作的、简易、轻便的铁制打窝工具,用它能在每亩田里撬直径1.3—1.5寸、深度0.8—1.0寸的小窝。同时小窝子在全田密度大,分布匀,而每窝苗数较少,麦苗在田里呈“大分散、小集中”状态,即为疏株密植。故该技术称为小撬点播(或小窝)疏株密植技术。它是以大穗为基础,密匀为中心,播种质量为关键,重底肥早追肥为保证,深沟高厢防除病虫杂草为前提的配套栽培技术。该技术自1979年推广以来,经受了多年不同地区不同自然条件考验,均获得显著经济效益。截止1983年累计
Skid is a specially made, simple, lightweight iron nesting tools, it can be used in every mu of pry 1.3-1.5 inches in diameter, the depth of 0.8-1.0 inch nest. At the same time the small nest in the field density, distribution, and fewer seedlings per plant, wheat seedlings in the field was “big scattered, small concentration” state, that is sparsely populated. Therefore, the technology is called pry on-demand (or small nest) sparse planting technology. It is based on big ears, dense uniform center, sowing quality as the key, basal fertilizer top-dressing to ensure that the deep-groove high-speed pest control weeds as a prerequisite for supporting cultivation techniques. Since the technology was popularized in 1979, it has undergone many years of tests in different natural conditions in different regions, and has obtained remarkable economic benefits. As of 1983 cumulative
