历来我区稻田一年三熟的主要轮作方式是早、晚稻冬薯。这种轮作方式晚稻、冬薯受灾害性天气影响很大,单产和总产不稳定。最近两年,特别今年以来,在英明领袖华主席提出的“抓纲治国”的伟大战略决策的指引下,全区大抓改制,一年三熟以稻、稻、薯为主,因地制宜,积极发展,改变种植时间,真正做到多种一造面积,多收一造产量,并要求达到造造高产。因此,提出改制就是要做到“一早、二改、三优势”。一早,即把种植季节提早;二改,即改晚造为中造,改冬薯为秋薯;三优势,即早造利用冬暖春早,在水利过关条件下,自然灾害少,温光好,发挥“科字号”品种迟 Historically, the main rotation pattern of paddy fields in our area has been early morning and late rice winter potato. This rotation mode late rice, winter potato affected by disastrous weather, yield and output is not stable. In the past two years, especially since the beginning of this year, guided by the great strategic decision of Chairman Hua of the wise leadership, “Grabing Gang with Governing the Country”, the whole district is paying great attention to reforming its system. Development, change planting time, a truly multi-area, more than a production, and requires the achievement of high yield. Therefore, the proposed reform is to achieve “early morning, the second reform, the three advantages.” Early in the morning, that is, the planting season earlier; second change, that is, to make late construction made in the change of winter potato for the autumn potato; three advantages, that is, early use of winter and warm spring early in the water clearance conditions, less natural disasters, temperature light Well, play “Section number” varieties late
