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１１６５１６７ｋｇ／ｈｍ２，条形穴栽培为１２３０２６７ｋｇ／ｈｍ２，比圆形穴栽培增产６５１００ｋｇ／ｈｍ２，增产率为５５９％。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。 Studies have shown that there are obvious marginal effects in the small group of more than one point. Compared with round-hole cultivation, bar-shaped hole cultivation can exert this marginal effect and improve the population size and population quality of large groups, and increase the yield by increasing tillers and ears and increasing grains. The yield of round hole cultivation was 1165167kg / hm2, that of barrow cultivation was 1230267kg / hm2, and that of round hole cultivation was 65100kg / hm2, yield increasing rate was 559%. Rice cultivation for the use of a pier two pier transplanting, bar-shaped hole machine inserted, bar-hole tray throwing seedling and pendulum seedlings provide a theoretical basis.
