使用机械插稻秧,首先要求秧苗符合机插条件。国内外在推广使用机械代替手工插秧的过程中,一条共同的经验,就是研究使用插秧机和改革手插时的育秧法,同时,还要建立一套培育机插秧苗的农艺措施。日本:1968年,日本有5,700多万亩水稻,由于沿用手插时的育秧法,虽有1.4万台插秧机,也发挥不了作用,1971年机插面积只占种植面积的9%。自从研究成功了室内培育带土小苗,又相继发展了室内培育带土中苗和相配套的带土苗插秧机以后,机插面积才迅速扩大。自1972年起,插秧机械化以每年7.8—15.6%的速度发展。1977年机插面积占种植面积的80.6%。室内培育带土小苗(叶龄2—2.5,苗高10—15厘米),发芽、绿化在室内。培育带土中苗时
The use of mechanical insertion of rice seedlings, the first requirement of seedlings meet machine insertion conditions. At home and abroad promote the use of machinery instead of hand-transplanting in the process, a common experience is to study the use of rice transplanter and hand when the practice of seedling raising law, at the same time, but also to establish a set of planting machine seedling agronomic measures. Japan: In 1968, Japan had more than 57 million mu of rice. Because of the seedling raising method when it was used in hand, there were 14,000 rice transplanters that did not work. In 1971, the area for machine-in was only 9% of the planted area. Since the successful research indoors nurturing soil seedlings, and have developed indoor nurturing soil with seedlings and supporting soil and seedlings with rice transplanter, the machine area was expanded rapidly. Since 1972, planting mechanization has been growing at a rate of 7.8-15.6% per annum. Machine inserted in 1977 accounted for 80.6% of acreage. Indoors nurturing soil seedlings (leaf age 2-2.5, seedling height 10-15 cm), germination, greening indoors. Cultivation with soil seedlings
