大豆窄行密植栽培是以选用宜密植、茎秆强壮、抗倒伏的矮秆或半矮秆品种为前提,进行缩垄增行,使单位土地面积上植株分布更合理、更均匀,从而充分利用土地及光能资源,增加群体干物质含量及绿叶面积,进而增加产量,经试验其增产效果在15%以上。现将大豆窄行密植栽培技术简述如下: 1.大垄窄行密植栽培法 常用的种植方式有两种:①垄距130~140厘米,垄上播6行,小行距16厘米。②
Slim narrow row close planting is based on the selection of dwarf or semi-dwarf varieties which should be close planting, strong stalks and lodging resistance, and the sowing is carried out by siding to make the distribution of plants in unit area more reasonable and uniform, so as to make full use of Land and light energy resources, increase the dry matter content of the population and the area of green leaves, thereby increasing the yield. The test results show that the yield increase effect is over 15%. Narrow row of dense planting cultivation technology now is as follows: 1. Wide ridge Narrow row close planting cultivation methods commonly used in planting there are two: ① Ridge 130 ~ 140 cm, sowing 6 rows, small row spacing of 16 cm. ②
