The Effects of Trickle Irrigation Culture and Catch in the Rain on Seed Production of Onion
점적관수(點滴灌水) 재배(栽培)가 양파의 채종량(採種量)에 미치는 영향(영향)을 구명(究明)코자 시험(試驗)하였던바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1 생육형질(생육혈질)로서 분약수(分藥數), 엽수(葉數), 초장(草長), 엽견장(葉堅長) 관화율(關花率)은 2월(月)-3월(月) 비닐하우스피복구(被覆區)와 3월(月) 비닐하우스 피복구(被覆區)에서 점적관수(點滴灌水)로 재배(栽培)할때에 가장 양호(良好)하였다. 2. 채종량(採種量)의 구성형질(構成形質)로서 화륜경(花輪梗핵), 화경당(花梗當) 소화수(小花數), 임실율(稔實率)은 2월(月)-3월(月) 비닐하우스 피복구(被覆區)나 3월(月) 비닐하우스 피복구(被覆區)에서 점적관수(點滴灌水)로 재배(栽培)할때에 가장 양호(良好)하였기에 채종량(採種量)도 가장 많았다.
The study was conducted to investigate the effect of the culture with trickle with trickle irrigation in transparent vinyl house on the seed productivity of onion. Growth, number o tiller and leavers, plant height, leaf sheath length, flowering rate, diameter of flower wheel, number of little flower per flower stalk and fertilization rate are best in the case of the seed production under the culture with trickle irrigation in transparent vinyl mulching house, catch in the rain with vinyl from February to March, so it is found that it is appropriate to plant the onion mother bulb under the culture with trickle irrigation in transparent vinyl mulching house, catch in the rain with vinyl from February to March in the Southern areas of Korea.
