大豆的亩产量究竟有多高?影响大豆产量的主要因素是什么?这是现在乃至将来的研究内容。我们认为提高大豆亩产,必须是单株管理,提高单株产量。怎样提高单株产量,首先要弄清如下问题:①大豆单株要有标准极限的营养面积,以便从土壤中得到充足的养分。②大豆单株要有标准极限的空间(通风量也叫空气补给量),以便满足对氧气和二氧化碳的需用量。③大豆单株要有标准极限的光照量(强度和时间)以便满足光合作用需要。④大豆单株要有标准极限的各种元素的供给量和吸收量。⑤大豆单株要有标准极限的需水量和供给量。⑥大豆病虫害破坏的叶片影响单株多少光合产物。⑦大豆单株管理在花荚期使
What is the high yield of soybean per acre? What are the main factors affecting soybean yield? This is the research content now and in the future. We think raising soybean production per mu must be managed on a single plant basis to increase yield per plant. How to improve the yield per plant, we must first understand the following questions: ① Soybean plants have a standard limit of nutrient area, in order to get enough nutrients from the soil. ② Soybean should have the standard limit of space (ventilation is also called air supply), in order to meet the oxygen and carbon dioxide consumption. ③ Soybean should have the standard limit of light intensity (intensity and time) in order to meet photosynthesis needs. ④ Soybean should have a standard limit of the supply of various elements and absorption. ⑤ soybean single standard limit of water demand and supply. ⑥ damage to soybean pests affect the number of leaves per plant photosynthetic products. ⑦ soybean plant management in the flower pod
