五十年代起,红花草一直是我县的主要冬季绿肥作物,历年种植面积在24～26万亩,平均亩产鲜草稳定在3,000斤左右,并出现过不少亩产6,000斤以上的高产垄片和万斤以上的高产田块。但从1978年开始,我县红花草种植面积不断减少,鲜草产量大幅度降低。由于红花生产的下降,致使土壤肥力得不到补偿,对粮食持续增产造成一定影响。因此,恢复和发展红花草生产已为当务之急。为此,我们于1982年,在本县高桥公社高桥三队的坑形垅建立了一片红花草高产示范样板,并设置了一系列附属对比试验。示范结果表明,只要把红花草生产认真当作一季作物来种,红花草生产不仅能够恢复,而且发展的潜力还很大。
Since the 1950s, safflower grass has been the main winter green manure crop in our county. Over the years, the planted area is between 24 and 26 million mu. The average yield per mu of fresh grass is about 3,000 kilograms. There have also been many high-yielding output of over 6,000 kg per mu Ridges and more than 10,000 pounds of high yield plots. However, since 1978, the planting area of safflower grass in our county has been continuously reduced, and the yield of fresh grass has been greatly reduced. Due to the decline of safflower production, the soil fertility will not be compensated, which will affect the continuous grain yield increase. Therefore, the restoration and development of red flowers and grass production has become a top priority. To this end, in 1982, we established a model demonstration of high yield of safflower in the pit form of the Takahashi three teams of Takahashi commune in Takahashi Prefecture and set up a series of subsidiary comparative experiments. Demonstration results show that as long as the production of safflower grass as a serious crop to species, safflower production not only to restore, but also great potential for development.
