根据典型半干旱区喀左县高油大豆生产现状,为促进高油大豆的生产,提高高油大豆的产量和品质,大力推广新技术。通过试验、调查掌握了高油大豆落花落荚的具体时间,以开花盛期、结荚初期脱落为最多。经过具体分析,明确了影响高油大豆花荚脱落的重要因素,主要是由于水、肥、光、热、病虫危害等一系列不合理的栽培及外界环境条件影响造成,详细阐述了综合防治高油大豆花荚脱落的技术措施,即选用优良品种、轮作倒茬、合理密植、深耕整地、增施农肥、配方施肥、适时灌水、及时摘心和防治病虫害,为高油大豆模式化高产栽培技术的推广提供依据。
According to the production status of high-oil soybean in Qazuo County in typical semi-arid area, in order to promote the production of high-oil soybean and increase the output and quality of high-oil soybean, the new technology is vigorously promoted. Through experiments, the investigation grasped the specific time of dropping soybean oil in high-oil soybean so as to bloom the peak of flowering and fall off in the early stage of podding. After a detailed analysis, it is clear that the important factors that affect the shedding of high-oil soybean flower pods are mainly caused by a series of unreasonable cultivation of water, fertilizer, light, heat and pests and diseases as well as external environmental conditions. The comprehensive prevention and treatment High-oil soybean flower pod shedding technical measures, that is, selection of fine varieties, rotation cropping, close planting density, plowing and land preparation, the application of fertilizer, formula fertilization, timely irrigation, in time topping and pest control for high-oil soybean high yielding cultivation techniques Promote provide basis.
