摘要
研究证实，一穴多株的小群体范围内，存在着明显的边际效应。条形穴栽培与圆形穴栽培相比，能够发挥这种边际效应，提高大群体的群体数量与群体质量，起到增蘖增穗增粒而显著增产的效果。圆形穴栽培产量为１１６５１６７ｋｇ／ｈｍ２，条形穴栽培为１２３０２６７ｋｇ／ｈｍ２，比圆形穴栽培增产６５１００ｋｇ／ｈｍ２，增产率为５５９％。为水稻栽培上采用一穴两墩插秧、条形穴机插、条形穴盘育抛秧及摆秧提供了理论依据。
The research proved that the boundary effect of one drill with many plants in a small range was evidentCompared with the circular drill,the strip drill could make the effectIt could increase the quantity and quality of the large population,which could increase the number of tillers,spikes and grains so as to make the notable increase in the yieldThe yield of circular drill was 11 65167 kg/hm2,and that of strip drill was 12 30267 kg/km2,which was 65100*8]kg/hm2 more than the former and the rate was 559%The study gave the theoretical prooves to take the ways of one drill with two plants,strip hill-drop machine planting,strip drilldish-nursery-throwing-seedling and displaying seedlings in the cultivation of rice
