辑编同志: 我们这里种水稻按照老习惯是春节前三犁三耙,春节后又三犁三耙,这样过多地耖耙,结果产量低,费力不赚钱。我读了《四川农业科技》1982年第4、5两期上的《自然免耕理论在水稻和小麦生产上的运用》一文后,受到启发,便决定以1.5亩责任田来按照“自然免耕法”种水稻。1982年冬将这块谷板田翻耕一次,1983年栽秧前再耖耙一次,总共只搞了两犁一耙即栽秧。在施肥方法上也采用你刊所介绍过的“底追一道清”。栽后20天用扑草净进行化学除草。灌浆后用磷酸二氢钾作根外追肥。采取这一系列措施后,这块田比其他田秧苗返青快,分蘖力强,生长旺,出穗率高,成熟早,亩产达到1,45 0斤(杂交稻),比多犁多耙的稻田增产21％。事实教育了那些当初对我的作法抱怀疑态度的干部和社员,现在他们则说:“科学种田很重要,省工省肥产量高。”因此他们要求编辑同志多刊登一些浅显易懂的农业科技知识,引导大家积
Editorial Comrades: Here we grow rice in accordance with the old habit of three harrows before the Spring Festival, after the Spring Festival and Sanli three rakes, so much rake, resulting in low yields, laborious not to make money. After reading the article “Application of Natural No-Tillage Theory in the Production of Rice and Wheat” of “Sichuan Agricultural Science and Technology” in 1982 and April 1984, I was inspired to decide that 1.5 mu Tillage method “species of rice. In 1982 the winter of this trough paddy field plowing once again in 1983 before rake rake again, a total of only a two rake that is planted seedlings. Fertilization methods are also used in your magazine introduced ”bottom chasing a clear.“ 20 days after planting with prometryn for chemical weeding. After filling with potassium dihydrogen phosphate for top dressing. After taking this series of measures, this field is faster than other field seedlings, with strong tillering ability, strong growth, high ear emergence rate and early maturity, yielding 1,450 kg (hybrid rice) per mu, Of the paddy field yield 21%. Facts have educated cadres and members who were skeptical about my practice. Now they say: ”Science farming is very important and provincial labor and fertilizer production is high." They therefore asked editors to publish some plainly-understood agricultural science and technology Knowledge, guide you plot
