在我国一年多熟制的省区,在栽培上我们既要满足作物的生育期,又要不误农时,因此要千方百计,采取各种措施,做到一早带多早,以达到全年稳产高产的目的。这里如何促进作物早熟有着十分重要意义。在一年一熟制的地区,要争取做到一年二熟,增加复种指数;在部分高寒地区要使作物免于生育后期受早霜危害,促进作物提早成熟就有着更大的现实意义。从1970年开始,我们在青海及浙江省的一些地方在麦类作物(大麦、小麦、青稞)的乳熟后
In our cooked-to-do provinces and autonomous regions for more than a year, we must not only cultivate the crops but also cultivate them. Therefore, we should try our best to take early measures to ensure that the crops are stable throughout the year The purpose of high yield. Here is how to promote crop precocity is very important. In a region cooked in a year, it is necessary to strive to achieve double cropping for one year and increase the multiple cropping index.
