根据国营蘆台农场1950年经验,水稻旱直播播种后就灌水、洗碱、及时落乾,出苗率很高,一般在80%左右。仅个别排水不良地区,遭受涝害及碱害,出苗不良。1951年同样方法播种灌溉,结果却造成严重的缺苗现象,出苗率最低的仅20%左右,最高的亦不过70%左右。二年方法相仿,出苗情形相差很多。现在把两年的作业调查记载,大田观察及简单试验的结果提出来和大家讨论,以便对蘆台鉴碱地区水稻使用机器旱直播的出苗问题,作进一步的了解。
According to the state-owned Lutai Farm’s experience in 1950, irrigation and soil washing were carried out after dry seeding of rice and seeding. The germination rate was very high, generally about 80%. Only a few poor drainage area, suffered waterlogging and alkali damage, poor emergence. The same method of sowing irrigation in 1951 resulted in a serious shortage of seedlings with the lowest germination rate of only about 20% and the highest of about 70%. Two years similar method, the emergence of a lot of difference. We will now discuss the results of the two-year homework survey, field observations and simple tests in order to further understand the emergent problems of rice direct-seeded plants in Lutai Kam base area.
