在毛主席革命路线指引下,我省从1972年开始用水稻雄性不育系配制杂交种,进行优势观察和小面积生产鉴定,1975年分别在山、丘、湖区上百个人民公社、国营农场和科研单位进行了较大面积的高产示范,都取得良好成绩。杂交水稻在丰产栽培条件下,比当家良种可增产2—3成,一般亩产1,000斤,少数丘块达1,300—1,400斤。在条件较差、产量较低的农田种植,增产幅度更大,甚至可成倍增产。而且米质较优良。杂交水稻的育成和推广,开辟了低产变高产,高产更高产的新途径。现将几年来的实践和应用上的一些经验体会分述如下。
Under the guidance of Chairman Mao’s revolutionary line, in 1972, our province began to formulate hybrids with male sterile lines of rice for superiority observation and identification of small-area production. In 1975, And scientific research units conducted a large area of high-yield demonstration, have achieved good results. Under high-yielding cultivation conditions, hybrid rice can increase yield by 2-3% compared with that of the elite. Generally, the yield per mu is 1,000 kg and the number of small plots reaches 1,300-1,400 kg. In poor conditions, the yield of low-yielding farmland, a greater yield increase, or even doubled production. And quality is better. The breeding and popularization of hybrid rice has opened up new ways for low-yielding and high-yielding, high-yielding and high-yielding. Now several years of practice and application of some experience on the experience are as follows.
