合理密植是大豆机械化栽培的主要增产措施之一。在合理的密度范围内,植株的田间分布状况对大豆单株生长发育影响甚大。因而,植株分布匀度是合理密植,发挥群体增产作用的前提。 田间植株分布不匀是当前大豆生产中的普遍现象,是影响大豆进一步高产的因素之一。因此,对大豆分布匀度问题做出客观的估价十分必要。我们于1979—1980两年,就大豆植株田间分布匀度问题进行了调查研究。下面结果仅供参考和商榷。
Reasonable close planting is one of the major measures to increase soybean mechanized cultivation. Within a reasonable range of density, the field distribution of plants had a great influence on the growth and development of soybean plants. Therefore, the distribution of plant density is reasonable close planting, play a role of group production increase. Uneven distribution of plants in the field is a common phenomenon in the current soybean production is one of the factors that affect further soybean production. Therefore, it is necessary to make an objective appraisal of the distribution of soybean. In the two years from 1979 to 1980, we conducted a survey on the field distribution uniformity of soybean plants. The following results for reference and discussion.
