亩产450斤大豆是当前可以普及的高产栽培产量指标。根据近几年试验结果,提出亩产450斤的各项生理参数及栽培措施。1.叶面积指数动态和最大叶面积指数试验证明,大豆的最大叶面积指数与生物产量和籽粒产量相关极显著。由于大豆单株自身调节能力极强,高产大豆的种植密度幅度很大。重要的是要保证群体相当繁茂,但又不郁蔽。要达到大豆亩产450 450 kg per mu yield of soybean is currently available high yield cultivation index. According to the test results in recent years, the proposed 450 kg per mu of physiological parameters and cultivation measures. 1. Leaf area index and maximum leaf area index test showed that the maximum leaf area index of soybean was significantly correlated with biomass and grain yield. Due to its strong ability to regulate the individual soybean, high-yielding soybean planting density range. It is important to ensure that the community is quite lush but not gloomy. To reach 450 acres of soybean
