1976年我省杂交水稻试种面积130万亩,分布在全省各个公社,基本上是成功的。在现有生产条件下,杂交水稻一般比常规稻当家品种每亩增产100—200斤。不少地方创造了一季亩产1,300—1,400斤的高产量。现将去年大面积试种示范的栽培经验,综合归纳如下。一、合理布局(一)作一季中稻栽培的适宜播期和插期在海拔较高,由于光温条件的限制,不适宜种植双季稻的地方,杂交水稻可作为一季中稻栽培,实行稻麦两熟、稻薯(马铃薯)两熟或稻油两熟。为了保证安全齐穗,海拔1,000米以上的地方,要在4月上旬播种,5月
In 1976, the area of hybrid rice planted in our province was 1.3 million mu, which was basically distributed in various communes in the province and was basically successful. Under the current production conditions, hybrid rice generally yield 100-200 kg per mu than conventional rice varieties. In many places, a high yield of 1,300-1,400 jin per mu was produced in the first quarter. Now last year, large-scale demonstration of planting cultivation experience, summarized as follows. First, a rational layout (A) for a quarter of midseason cultivation sowing and insertion at high altitude, due to light and temperature conditions, is not suitable for planting double cropping paddy rice, hybrid rice can be used as a quarter of rice cultivation, the implementation of rice and wheat Two ripening, rice (potato) two cooked or rice oil two cooked. In order to ensure the safety of the ear, more than 1,000 meters above sea level, to sow in early April, May
