我区50年代中期植蔗面积曾达33.5—38.8万亩,单产上升到3.0—3.1吨。由于左倾路线的影响,1959年以后植蔗面积和产量均大幅度下降。1961年面积降到15.8万亩,单产仅0.86吨。1964年以后虽有回升,但面积一直在20—25万亩内波动,单产在2.5吨内徘徊。党的十一届三中全会以后,农村各项政策均得到调整和落实,对甘蔗生产的恢复和发展十分有利,1982年全区单产达2.8吨,但仍低于50年代最高单产水平,也低于全省和全国平均水平。这说明我区单产潜力很大,而且急待提高。影响甘蔗产量的原因是多方面的,本文仅从技术方面来谈谈自己的看法和建议。一、内江蔗区自然特点我区地处四川盆地中心,属中亚热带湿润
In the mid-1950s, the area of sugarcane in our area reached 33.5-38.8 mu, and the yield rose to 3.0-3.1 tons. Due to the left-leaning route, the area and yield of sugarcane dropped significantly after 1959. In 1961, the area dropped to 158,000 mu, yielding only 0.86 tons. Although 1964 after the rebound, but the area has been fluctuating within the 20-25 million mu, hovering within 2.5 tons. After the Third Plenary Session of the 11th CPC Central Committee, all rural policies were readjusted and implemented, and the recovery and development of sugar cane production was very favorable. In 1982, the yield in the entire region reached 2.8 tons, but still lower than the highest yield in the 1950s. Lower than the province and the national average. This shows that my district yields a lot of potential, but also urgent need to improve. There are many reasons that affect the output of sugarcane. This article only talks about your own opinions and suggestions from the technical aspects. First, the natural characteristics of Neijiang sugarcane area I District is located in the center of Sichuan Basin, is a subtropical humid
